The Disclaimer Trust in Minnesota: Minnesota Sets No Deadline, and Federal Law Gives You Nine Months

The structure, and the Minnesota problem it answers

Minnesota’s estate tax exclusion is $3,000,000, and Minnesota does not let a widow or widower use whatever the first spouse did not. Both facts are set out, with the statutes and the Department of Revenue’s own statement, on the Minnesota estate tax page and the 2026 exemption card. This page assumes them and does not re-argue them.

The arithmetic they produce is what drives the structure described here. A married couple who leave everything to each other outright pay no estate tax at the first death, because 26 U.S.C. § 2056(a) allows a deduction from the gross estate, “except as limited by subsection (b),” of

an amount equal to the value of any interest in property which passes or has passed from the decedent to his surviving spouse, but only to the extent that such interest is included in determining the value of the gross estate.

That assumes a citizen spouse. Section 2056(d)(1)(A) provides that if the surviving spouse “is not a citizen of the United States,” then “no deduction shall be allowed under subsection (a)” — with the qualified domestic trust in § 2056(d)(2) as the exception to that exception.

Everything then sits in the survivor’s estate, where one $3,000,000 exclusion meets the whole pile. The first spouse’s exclusion is used on nothing and expires with them.

The classic answer is a mandatory bypass trust: the first spouse’s will or trust funds a family trust up to the exclusion no matter what, and the survivor never owns that money outright. Plenty of couples do not want that, and say so in the drafting meeting.

The disclaimer trust is the version that defers the decision. The will or revocable trust leaves everything to the surviving spouse outright and adds a provision that anything the surviving spouse refuses passes instead into a bypass trust for the surviving spouse’s benefit. Nobody has to guess, years in advance, what the estate will be worth or what the exclusion will be. The survivor decides afterward, with the actual balance sheet and the actual figure in front of them.

The cost of that flexibility is that everything now depends on an act the survivor has to perform correctly, on a clock, in the worst months of their life. The rest of this page is that act.

Minnesota’s disclaimer act, and the deadline it does not contain

Minnesota enacted the Uniform Disclaimer of Property Interests Act in 2009. Minn. Stat. § 524.2-1101:

Sections 524.2-1101 to 524.2-1116 may be cited as the “Uniform Disclaimer of Property Interests Act.”

That is sixteen sections, § 524.2-1101 through § 524.2-1116. There is no § 524.2-1117. All sixteen were enacted by Laws 2009, ch. 67; seven of them — §§ 524.2-1103, -1104, -1106, -1107, -1114, -1115 and -1116 — were amended by Laws 2012, ch. 143, art. 4. Nothing in the subpart has been touched since.

Section 524.2-1103 makes the act the only route:

Sections 524.2-1101 to 524.2-1116 are the exclusive means by which a disclaimer may be made under Minnesota law regardless of whether it is qualified under section 2518 of the Internal Revenue Code of 1986 as defined in section 291.005, subdivision 1, clause (3).

Read the last clause. The act contemplates disclaimers that are not qualified under § 2518, which tells you the two systems are separate — and § 524.2-1105 confirms it in a single sentence:

A disclaimer may be made at any time unless it is barred under section 524.2-1106.

At any time. Minnesota’s act imposes no nine-month limit, no six-month limit, and no limit at all. What it imposes are the bars in § 524.2-1106, and those are about conduct, not the calendar.

What Minnesota requires on the face of the document

Section 524.2-1107(a) sets who may disclaim and what:

A person may disclaim, in whole or in part, any interest in or power over property, including a power of appointment. A person may disclaim the interest or power even if its creator imposed a spendthrift provision or similar restriction on transfer or a restriction or limitation on the right to disclaim.

Paragraph (c) sets the form — one sentence about what the document must be, a second about what must happen to it. No count is stated here for the same reason none is stated for paragraph (d) below: the statute does not number the items, and the fourth predicate is a compound that can be read as one requirement or two.

To be effective, a disclaimer must be in writing, declare the writing as a disclaimer, describe the interest or power disclaimed, and be signed by the person or fiduciary making the disclaimer and acknowledged in the manner provided for deeds of real estate to be recorded in this state. In addition, for a disclaimer to be effective, an original of the disclaimer must be delivered or filed in the manner provided in section 524.2-1114.

Writing; self-identification as a disclaimer; description of the interest or power; signature; acknowledgment to the standard Minnesota uses for deeds that are going to be recorded; and then delivery or filing of an original. A signed letter to the trustee saying “I don’t want it” is a writing and it is signed. It does not declare itself a disclaimer, it does not describe the interest, and it is not acknowledged.

Section 524.2-1114 says where the original goes, and the answer depends on what is being disclaimed. For an interest created by will other than an interest in a testamentary trust, it goes to the personal representative of the estate, or, if none is serving, it is filed with the court in a county where venue for administration would be proper. For an interest in a testamentary trust, it goes to the trustee then serving, or to the personal representative if no trustee is serving. For an interest in an inter vivos trust, it goes to the trustee then serving. Delivery “may be effective by personal delivery, first-class mail, or any other method that results in its receipt.” Only one class of mail gets the postmark rule: “A disclaimer sent by first-class mail is deemed to have been delivered on the date it is postmarked.” Delivery by any other method is effective on receipt. Where real estate is involved, paragraph (l) presumes delivery on recording, and § 524.2-1115 adds that the disclaimer does not give constructive notice to the world unless it contains a legal description and is recorded with the county recorder or registrar of titles.

Paragraph (e) of § 524.2-1107 is the one that ends the conversation:

A disclaimer becomes irrevocable when the disclaimer is delivered or filed pursuant to section 524.2-1114 or it becomes effective as provided in sections 524.2-1108 to 524.2-1113, whichever occurs later.

And paragraph (f) forecloses the natural workaround: “A disclaimer made under sections 524.2-1101 to 524.2-1116 is not a transfer, assignment, or release.” A surviving spouse who signs the wrong thing and then tries to fix it by handing the property along has made a gift, not a disclaimer.

The five bars

Section 524.2-1106 is short and worth reading whole:

(a) A disclaimer is barred by a written waiver of the right to disclaim.

(b) A disclaimer of an interest in property is barred if any of the following events occur before the disclaimer becomes effective:

(1) the disclaimant accepts the portion of the interest sought to be disclaimed;

(2) the disclaimant voluntarily assigns, conveys, encumbers, pledges, or transfers the portion of the interest sought to be disclaimed or contracts to do so;

(3) the portion of the interest sought to be disclaimed is sold pursuant to a judicial sale; or

(4) the disclaimant is insolvent when the disclaimer becomes irrevocable.

(c) Acceptance of a distribution from a trust shall constitute acceptance of only that portion of the beneficial interest in that trust that has been distributed, and shall not constitute acceptance or bar disclaimer of that portion of the beneficial interest in the trust that has not yet been distributed.

(d) A disclaimer, in whole or in part, of the future exercise of a power held in a fiduciary capacity is not barred by its previous exercise.

(e) A disclaimer, in whole or in part, of the future exercise of a power not held in a fiduciary capacity is not barred by its previous exercise unless the power is exercisable in favor of the disclaimant.

(f) A disclaimer of an interest in, or a power over, property which is barred by this section is ineffective.

Five bars: a written waiver, plus the four events in paragraph (b). Clause (b)(4) is the one that catches people by surprise, because it has nothing to do with estate planning — a disclaimant who is insolvent when the disclaimer becomes irrevocable cannot disclaim, and § 524.2-1102(9) defines insolvent as debts greater than assets at fair valuation, with a presumption of insolvency for a person “generally not paying debts as they become due.” The same clause carries two carve-outs that cut both ways: assets do not include property transferred, concealed or removed to hinder, delay or defraud creditors, or transferred in a manner making the transfer voidable, and debts do not include an obligation “to the extent it is secured by a valid lien or property of the debtor not included as an asset.” Federal law reaches the same place from the other side: 26 C.F.R. § 25.2518-1(c)(2) provides that a disclaimer voidable by creditors is still capable of being qualified, but “a disclaimer that is wholly void or that is voided by the disclaimant’s creditors cannot be a qualified disclaimer.”

Where the property actually goes

Section 524.2-1108 answers this, and it starts by saying where it does not apply. Paragraph (a):

Except for a disclaimer governed by section 524.2-1109 or 524.2-1110, the rules in paragraphs (b) to (d) apply to a disclaimer of an interest in property.

Hold those two exceptions — jointly held property and a trustee’s disclaimer — and read on. For everything else, paragraph (c) is the sentence the structure hangs on:

The disclaimed interest passes according to any provision in the instrument creating the interest providing for the disposition of the interest, should it be disclaimed, or as disclaimed interests in general.

That clause is why a disclaimer trust has to be drafted before the first death. The bypass trust is a provision in the will or the revocable trust “providing for the disposition of the interest, should it be disclaimed, or as disclaimed interests in general.” Without it, paragraph (d) takes over: an individual disclaimant is treated as having “died immediately before the interest was created,” subject to two qualifiers written into the same clause — if the interest was contingent on surviving to the time of distribution, the disclaimant is treated as dying immediately before the time for distribution instead, and if the disclaimant’s descendants would share by representation, the interest passes only to those descendants who survive the time of distribution. A non-individual disclaimant is treated as if it did not exist. And a future interest held by someone else accelerates, while a future interest held by the disclaimant does not.

So within § 524.2-1108 the property does not float. It goes to whoever the instrument names as the next taker — the children, outright, in most simple wills. If the instrument names nobody, Minn. Stat. § 524.2-604 routes a failed devise, in both of its paragraphs and in both cases “[e]xcept as provided in section 524.2-603”: a failed non-residuary devise “becomes a part of the residue,” and a failed residuary share passes “to the other residuary devisee, or to other residuary devisees in proportion to the interest of each in the remaining part of the residue.” Section 524.2-603 is Minnesota’s antilapse rule, and its subdivision 1 reaches a devisee who “is dead at the time of execution of the will, fails to survive the testator, or is treated as if the devisee predeceased the testator,” where that devisee is a grandparent or a lineal descendant of a grandparent of the testator, and sends the devise to that devisee’s issue who survive the testator by 120 hours. Whether it is triggered by a disclaimant whom § 524.2-1108(d)(1) treats as having died immediately before the interest was created is a question of law this page does not answer. Section 524.2-101(a) catches whatever is left: the intestate estate “consists of any part of the decedent’s estate … not disposed of by will,” and it “passes by intestate succession to the decedent’s heirs as prescribed in this chapter, except as modified by the decedent’s will.”

A disclaimer aimed at a trust that does not exist in the document is a disclaimer in favor of whoever those rules produce, with no trust, no trustee, and no continuing benefit to the surviving spouse.

The joint homestead and the joint account run on different rules

The first of the two categories § 524.2-1108(a) sets aside is jointly held property, which is how most married Minnesotans hold the house and the accounts. Both the Minnesota routing rule and the federal clock change for it, and they change in the direction that hurts. The second category — a trustee’s disclaimer under § 524.2-1110 — is a fiduciary act rather than a form of co-ownership, no federal clock changes for it, and it is treated on its own further down.

Jointly held property — where it goes. Minn. Stat. § 524.2-1109(c):

An interest in jointly held property disclaimed by a surviving holder of the property passes as if the disclaimant predeceased the holder to whose death the disclaimer relates.

That is a statutory destination, not the instrument’s. The will’s bypass-trust provision does not reach it, because the paragraph that sends a disclaimed interest where the instrument says — § 524.2-1108(c) — is one of the paragraphs § 524.2-1108(a) switches off for a disclaimer governed by § 524.2-1109.

Jointly held property — how much of it. Paragraph (a) of the same section gives a fraction, not the whole:

(a) Upon the death of a holder of jointly held property:

(1) if, during the deceased holder’s lifetime, the deceased holder could have unilaterally regained a portion of the property attributable to the deceased holder’s contributions without the consent of any other holder, another holder may disclaim, in whole or in part, a fractional share of that portion of the property attributable to the deceased holder’s contributions determined by dividing the number one by the number of joint holders alive immediately after the death of the holder to whose death the disclaimer relates; and

(2) for all other jointly held property, another holder may disclaim, in whole or in part, a fraction of the whole of the property the numerator of which is one and the denominator of which is the product of the number of joint holders alive immediately before the death of the holder to whose death the disclaimer relates multiplied by the number of joint holders alive immediately after the death of the holder to whose death the disclaimer relates.

Paragraph (b) fixes the timing: a disclaimer under paragraph (a) “takes effect as of the death of the holder of jointly held property to whose death the disclaimer relates.”

The other excepted section is short. Minn. Stat. § 524.2-1110:

If a trustee having the power to disclaim under the instrument creating the fiduciary relationship or pursuant to court order disclaims an interest in property that otherwise would have become trust property, the interest does not become trust property.

The federal clock is the harder half. 26 C.F.R. § 25.2518-2(c)(4)(i) runs two clocks on one house:

Except as provided in paragraph (c)(4)(iii) of this section (with respect to joint bank, brokerage, and other investment accounts), in the case of an interest in a joint tenancy with right of survivorship or a tenancy by the entirety, a qualified disclaimer of the interest to which the disclaimant succeeds upon creation of the tenancy must be made no later than 9 months after the creation of the tenancy regardless of whether such interest can be unilaterally severed under local law. A qualified disclaimer of the survivorship interest to which the survivor succeeds by operation of law upon the death of the first joint tenant to die must be made no later than 9 months after the death of the first joint tenant to die regardless of whether such interest can be unilaterally severed under local law and, except as provided in paragraph (c)(4)(ii) of this section (with respect to certain tenancies created on or after July 14, 1988), such interest is deemed to be a one-half interest in the property.

The half the survivor took on creation of the tenancy had its own nine months, and they ran from the creation, not from the death. The regulation’s own examples say so without hedging. Take Example (7), a joint tenancy with right of survivorship that state law lets either tenant sever. The regulation’s own words, conditional and all: “Assuming that the other requirements of section 2518(b) are satisfied, A has made a qualified disclaimer of the one-half survivorship interest (but not the interest retained by A upon the creation of the tenancy, which may not be disclaimed by A). The result is the same whether or not A and B are married and regardless of the proportion of consideration furnished by A and B in purchasing the property.” Example (8) puts the identical parenthetical on a tenancy by the entirety between spouses that state law does not permit either tenant to sever. The conditional governs whether the disclaimer is qualified. The parenthetical does not: what the survivor already owned is outside the disclaimer either way.

That is the case, the regulation adds, “regardless of the portion of the property attributable to consideration furnished by the disclaimant and regardless of the portion of the property that is included in the decedent’s gross estate under section 2040 and regardless of whether the interest can be unilaterally severed under local law.” Paragraph (c)(4) “is applicable for disclaimers made on or after December 31, 1997.”

Joint accounts are carved out and treated differently. Section 25.2518-2(c)(4)(iii) covers joint bank, brokerage and other investment accounts. Where the transferor could unilaterally regain their own contributions without the other cotenant’s consent, so that the transfer was never a completed gift, “the transfer creating the survivor’s interest in the decedent’s share of the account occurs on the death of the deceased cotenant. Accordingly, if a surviving joint tenant desires to make a qualified disclaimer with respect to funds contributed by a deceased cotenant, the disclaimer must be made within 9 months of the cotenant’s death.” Then the limit: “The surviving joint tenant may not disclaim any portion of the joint account attributable to consideration furnished by that surviving joint tenant.”

What makes it a qualified disclaimer

The tax consequence is entirely federal. 26 U.S.C. § 2518(a):

For purposes of this subtitle, if a person makes a qualified disclaimer with respect to any interest in property, this subtitle shall apply with respect to such interest as if the interest had never been transferred to such person.

26 U.S.C. § 2046 carries that into the estate tax in one line: “For provisions relating to the effect of a qualified disclaimer for purposes of this chapter, see section 2518.” And § 2518(b) defines the term:

For purposes of subsection (a), the term “qualified disclaimer” means an irrevocable and unqualified refusal by a person to accept an interest in property but only if—

(1) such refusal is in writing,

(2) such writing is received by the transferor of the interest, his legal representative, or the holder of the legal title to the property to which the interest relates not later than the date which is 9 months after the later of—

(A) the day on which the transfer creating the interest in such person is made, or

(B) the day on which such person attains age 21,

(3) such person has not accepted the interest or any of its benefits, and

(4) as a result of such refusal, the interest passes without any direction on the part of the person making the disclaimer and passes either—

(A) to the spouse of the decedent, or

(B) to a person other than the person making the disclaimer.

Four numbered requirements, sitting under a lead-in that adds two more adjectives — the refusal must be irrevocable and unqualified. The regulation splits the same content into five: 26 C.F.R. § 25.2518-2(a) lists irrevocable and unqualified, in writing, delivered to the right person within the time limit, no acceptance of the interest or its benefits, and passage to the decedent’s spouse or to someone other than the disclaimant without direction by the disclaimant.

Two of the five carry detail the statute leaves out. On the document, § 25.2518-2(b)(1): “A disclaimer is a qualified disclaimer only if it is in writing. The writing must identify the interest in property disclaimed and be signed either by the disclaimant or by the disclaimant’s legal representative.” Federal law wants the interest identified and the paper signed. It does not want it notarized — no form of the word “acknowledge” and no form of the word “notary” appears anywhere in 26 U.S.C. § 2518 or in 26 C.F.R. §§ 25.2518-1, -2 or -3, all four of which were searched in full for this page. The acknowledgment is Minnesota’s requirement under § 524.2-1107(c) and nobody else’s. What the Minnesota act then does with a disclaimer that is qualified under § 2518 is § 524.2-1104’s subject, and that section is quoted below.

On delivery, the regulation’s list at paragraph (b)(2) is one name longer than the statute’s: the transferor, the transferor’s legal representative, the holder of legal title, or the person in possession of the property.

For a death-time transfer the clock starts at the death. Paragraph (c)(3)(i) of the regulation: “With respect to transfers made by a decedent at death or transfers that become irrevocable at death, the transfer creating the interest occurs on the date of the decedent’s death, even if an estate tax is not imposed on the transfer.” Two mechanical softenings exist, and no more. Paragraph (c)(2) treats a timely mailing as a timely delivery if the mailing requirements of paragraphs (c)(1), (c)(2) and (d) of 26 C.F.R. § 301.7502-1 are met, and if the last day of the nine months falls on a Saturday, Sunday or legal holiday, delivery on the next day that is not one of those is timely.

What does move is the day the nine months start from, and paragraph (c)(3)(i) is a list of the ways. A person under 21 gets a later start date rather than an extension — § 2518(b)(2)(B) measures from the day they attain age 21, and § 25.2518-2(d)(3) gives them until nine months after their twenty-first birthday. The holder of a general power of appointment runs nine months from the transfer creating the power. For a nongeneral power, the holder, the permissible appointees and the takers in default “must disclaim within a 9-month period after the original transfer that created or authorized the creation of the power.” A remainderman of property an executor elects to treat as qualified terminable interest property “must disclaim within 9 months of the transfer creating the interest, rather than 9 months from the date such interest is subject to tax under section 2044 or 2519.” A person who takes because someone else made a qualified disclaimer runs from “the transfer creating the interest in the preceding disclaimant.” And jointly held property runs on the two clocks set out in the section above.

The effect, once it works, is stated at § 25.2518-1(b): the disclaimed interest “is treated as if it had never been transferred to the person making the qualified disclaimer,” is “considered as passing directly from the transferor of the property to the person entitled to receive the property as a result of the disclaimer,” and the disclaimant “is not treated as making a gift.” 26 C.F.R. § 20.2056(d)-2(a) applies that to the surviving spouse specifically: the effectiveness of a spouse’s disclaimer “will be determined by section 2518 and the corresponding regulations,” and a qualified disclaimer means “the property interest disclaimed is treated as if such interest had never been transferred to the surviving spouse.”

That is the whole mechanism. Property the surviving spouse disclaims never passed to the spouse, so no marital deduction is taken for it under § 2056(a), so it is taxed in the first spouse’s estate — where the first spouse’s exclusion is sitting unused — and the surviving spouse never owned it. Whether it stays out of the surviving spouse’s own gross estate at the second death is a separate question, answered by the terms of the trust it landed in, and the limits those terms have to respect are two sections below.

Minnesota picks the result up rather than computing its own. Minn. Stat. § 291.016, subd. 1 provides that “the Minnesota taxable estate equals the federal taxable estate as provided under section 2051 of the Internal Revenue Code, without regard to whether the estate is subject to the federal estate tax,” subject to three adjustments, and 26 U.S.C. § 2051 defines the federal taxable estate as the gross estate less “the deductions provided for in this part” — the part containing § 2056. Section 524.2-1104 closes the loop from the Minnesota side, and it names the one thing it does not override:

Notwithstanding any other provision of this chapter, other than section 524.2-1106, if, as a result of a disclaimer or transfer, the disclaimed or transferred interest is treated pursuant to the provisions of section 2518 of the Internal Revenue Code of 1986 … as never having been transferred to the disclaimant, then the disclaimer or transfer is effective as a disclaimer under sections 524.2-1101 to 524.2-1116.

The “notwithstanding” clause carves out exactly one section and names it: § 524.2-1106, the bars. A tax-qualified disclaimer does not run around those. The clause carves out nothing else in the subpart.

The 2025 Form M706 instructions confirm that the Department expects to see the paperwork, in a bullet whose closing words scope it. Under “You must attach the following to Form M706 …”, one of the required items is:

copies of the wills, property appraisals or sales documents, trust agreements, disclaimers, financial documents, etc., that verify balances and/or stock or bond prices

The duty runs to the documents that verify the numbers on the return, not to every piece of paper in the file.

Acceptance closes the door first

The nine months is the deadline people remember. Acceptance is the one they lose. 26 C.F.R. § 25.2518-2(d)(1):

A qualified disclaimer cannot be made with respect to an interest in property if the disclaimant has accepted the interest or any of its benefits, expressly or impliedly, prior to making the disclaimer. Acceptance is manifested by an affirmative act which is consistent with ownership of the interest in property. Acts indicative of acceptance include using the property or the interest in property; accepting dividends, interest, or rents from the property; and directing others to act with respect to the property or interest in property.

Three named acts, and the list is illustrative rather than closed — the regulation writes “[a]cts indicative of acceptance include …” The same paragraph then carries four things that are not acceptance and two that are:

1. “[M]erely taking delivery of an instrument of title, without more, does not constitute acceptance.”
2. A disclaimant is not treated as accepting “merely because under applicable local law title to the property vests immediately in the disclaimant upon the death of a decedent.”
3. “The acceptance of one interest in property will not, by itself, constitute an acceptance of any other separate interests created by the transferor and held by the disclaimant in the same property.”
4. For residential property held in joint tenancy by some or all of the residents, a joint tenant “will not be considered to have accepted the joint interest merely because the tenant resided on the property prior to disclaiming his interest in the property.”
5. Two acts are fatal on their face: “The exercise of a power of appointment to any extent by the donee of the power is an acceptance of its benefits,” and “the acceptance of any consideration in return for making the disclaimer is an acceptance of the benefits of the entire interest disclaimed.”

Paragraph (d)(2) adds a carve-out for the very common case where the surviving spouse is also the personal representative: acts taken “in the exercise of fiduciary powers to preserve or maintain the disclaimed property shall not be treated as an acceptance of such property or any of its benefits.” The regulation’s own examples are harvesting a crop and general maintenance of a home. A fiduciary still “cannot retain a wholly discretionary power to direct the enjoyment of the disclaimed interest.”

Minnesota’s contribution is § 524.2-1106(c), which keeps a single trust distribution from poisoning the rest: accepting a distribution from a trust accepts only the portion distributed and does not bar a disclaimer of the portion not yet distributed.

What the surviving spouse may keep over the bypass trust

Requirement four is where disclaimer trusts fail on the merits rather than the calendar. Section 2518(b)(4) demands that the interest pass “without any direction on the part of the person making the disclaimer,” and subparagraph (A) is the exception that makes the whole structure possible: the property may pass “to the spouse of the decedent.” When someone other than the spouse disclaims and part of the property comes back to them anyway, paragraph (e)(3) of the regulation disqualifies the disclaimer as to that portion — but only on both of two conditions: “(i) The disclaimant also has a right to receive such property as an heir at law, residuary beneficiary, or by any other means; and (ii) The disclaimant does not effectively disclaim these rights …” Condition (ii) is also the cure. Disclaim the returning rights too and the problem goes away, which is exactly what Example (1) of paragraph (e)(5) says: “Had B also disclaimed B’s 50 percent interest in the residuary estate, the disclaimer would have been a qualified disclaimer under section 2518 of the entire interest in the home (assuming the remaining requirements of a qualified disclaimer were satisfied).” Where the returning portion is left undisclaimed and “is not severable property or an undivided portion of the property,” the disclaimer fails as to the whole. A disclaimer by the surviving spouse into a trust that benefits the surviving spouse is not disqualified by that fact alone.

The regulation draws the line precisely. Section 25.2518-2(e)(1) disqualifies a disclaimer if

(i) The disclaimant, either alone or in conjunction with another, directs the redistribution or transfer of the property or interest in property to another person (or has the power to direct the redistribution or transfer of the property or interest in property to another person unless such power is limited by an ascertainable standard); or

(ii) The disclaimed property or interest in property passes to or for the benefit of the disclaimant as a result of the disclaimer (except as provided in paragraph (e)(2) of this section).

And paragraph (e)(2), for the spouse:

In the case of a disclaimer made by a decedent’s surviving spouse with respect to property transferred by the decedent, the disclaimer satisfies the requirements of this paragraph (e) if the interest passes as a result of the disclaimer without direction on the part of the surviving spouse either to the surviving spouse or to another person. If the surviving spouse, however, retains the right to direct the beneficial enjoyment of the disclaimed property in a transfer that is not subject to Federal estate and gift tax (whether as trustee or otherwise), such spouse will be treated as directing the beneficial enjoyment of the disclaimed property, unless such power is limited by an ascertainable standard.

The regulation’s examples run the exact fact pattern. In Example (4), the surviving spouse disclaims 30 percent of a marital trust, the will sends the disclaimed portion to a nonmarital trust in which the spouse has an income interest and no power to appoint or invade corpus, and the disclaimer satisfies § 2518(b)(4). In Example (5), the same spouse also holds a testamentary nongeneral power to appoint among designated beneficiaries that is not limited by an ascertainable standard — and the disclaimer fails unless the spouse also disclaims the power over the fraction of the nonmarital trust attributable to the disclaimed property. The regulation does the arithmetic: $250,000 of disclaimed property into a $750,000 trust means disclaiming the power over one-third of the corpus, “regardless of whether the nongeneral power is testamentary or inter vivos.” Example (6) permits a power to invade corpus “if needed for A’s health or maintenance,” together with an independent trustee’s discretionary power to distribute for the spouse’s happiness. Example (7) permits the familiar noncumulative annual right to withdraw the greater of $5,000 or 5 percent of principal.

Those limits are not decoration. A general power of appointment held at death pulls the property back into the gross estate under 26 U.S.C. § 2041(a)(2), and § 2041(b)(1)(A) provides that “[a] power to consume, invade, or appropriate property for the benefit of the decedent which is limited by an ascertainable standard relating to the health, education, support, or maintenance of the decedent shall not be deemed a general power of appointment.” Section 2041(b)(2) treats the lapse of a post-1942 power as a release, but only to the extent the property that could have been appointed by the lapsed power exceeded in value, at the time of the lapse, “the greater of” $5,000 or 5 percent of the assets out of which the lapsed powers could have been satisfied — the same two figures that appear in Example (7). Whether any particular bypass trust stays outside a particular survivor’s estate depends on its terms, and this page does not evaluate anyone’s terms.

Partial disclaimers, which is how these are funded

In this structure the disclaimer is sized to the exclusion rather than to the estate, which makes it partial, which brings its own rules.

Minnesota’s are permissive. Section 524.2-1107(d): “A partial disclaimer may be expressed as a fraction, percentage, monetary amount, specific property, term of years, portion of a beneficial interest in or right to distributions from a trust, limitation of a power, or any other interest or estate in the property.” Named forms, and then a catch-all that swallows anything they missed.

Federal law is narrower. Section 2518(c)(1) treats a disclaimer of “an undivided portion of an interest” that meets the section’s requirements as a qualified disclaimer of that portion, and 26 C.F.R. § 25.2518-3(b) defines the term with teeth:

An undivided portion of a disclaimant’s separate interest in property must consist of a fraction or percentage of each and every substantial interest or right owned by the disclaimant in such property and must extend over the entire term of the disclaimant’s interest in such property and in other property into which such property is converted. A disclaimer of some specific rights while retaining other rights with respect to an interest in the property is not a qualified disclaimer of an undivided portion of the disclaimant’s interest in property.

Section 25.2518-3(a)(1)(i) adds that each interest separately created by the transferor is treated as a separate interest, so a life tenant who is also a remainderman may disclaim either interest or an undivided portion of either — but “could not … make a qualified disclaimer of the income interest for a certain number of years.” Paragraph (a)(1)(ii) permits a disclaimer of severable property, defined as property “which can be divided into separate parts each of which, after severance, maintains a complete and independent existence,” using shares of stock as the example. Paragraph (a)(1)(iii) treats a power of appointment as a separate interest that may be disclaimed on its own, and only if “any right to direct the beneficial enjoyment of the property which is retained by the disclaimant is limited by an ascertainable standard.”

Paragraph (c) allows a disclaimer of a specific pecuniary amount, on a condition: no income or other benefit of the disclaimed amount may inure to the disclaimant before or after the disclaimer, so “the amount disclaimed and any income attributable to such amount must be segregated” from the rest, valued at the date of the disclaimer or on a basis fairly representative of intervening value changes. Paragraph (a)(2) is the trust-specific trap — disclaiming the income from particular assets inside a trust while continuing to take income from the rest is not qualified unless the disclaimer actually removes those assets from the trust and sends them, without direction, to someone other than the disclaimant or to the decedent’s spouse.

If the surviving spouse cannot act

The nine months does not pause for a stroke.

Minnesota’s act contemplates someone acting for the disclaimant, and it sets a condition. Section 524.2-1102(6) defines a fiduciary as “a personal representative, trustee of a trust, agent acting under a power of attorney, conservator, or other person authorized to act as a fiduciary with respect to the property of another person.” Section 524.2-1107(b) then provides that with court approval a fiduciary may disclaim in a representative capacity, and that “[w]ithout court approval, a fiduciary may disclaim … if and to the extent that the instrument creating the fiduciary relationship explicitly grants the fiduciary the right to disclaim.” The same paragraph lets a custodial parent disclaim for a minor child with no conservator, with court approval.

For an agent, the instrument creating the fiduciary relationship is the power of attorney. Minnesota’s statutory short form grants authority by category, and § 523.23 prints “beneficiary transactions” as line (G). Section 523.24, subd. 7 defines that category to authorize the attorney-in-fact, as to any trust, probate estate, guardianship, conservatorship, escrow, custodianship, benefit plan, individual retirement asset or other fund in which the principal claims an interest, “to accept, reject, disclaim, receive, receipt for, sell, assign, release, pledge, exchange, or consent to a reduction in or modification of any share in or payment from the fund.” The word is there. Whether it is granted depends on whether that line was selected on the form the principal signed, years earlier, for reasons that had nothing to do with this.

For a conservator, there is no shortcut. Section 524.5-411(a)(6) requires notice to affected persons, a hearing, and “express authorization of the court” before a conservator may, among other listed acts, “renounce or disclaim any interest by testate or intestate succession or by transfer inter vivos.” The notice list in paragraph (b) reaches the person subject to conservatorship, the conservator, the heirs at law, any state or county agency paying benefits or holding an asset assessment, and the beneficiaries of the existing will or revocable trust. That is a proceeding, and it has to finish inside nine months that started running on the day of the death.

The other Minnesota structure, and how the two differ

Minnesota offers an alternative that operates on the estate tax return rather than on the property. Minn. Stat. § 291.03, subd. 1d(a) allows a marital deduction election under 26 U.S.C. § 2056(b) to be made “for Minnesota estate tax purposes regardless of whether the election is made for federal estate tax purposes,” and provides that the gross estate includes property in which the decedent had a qualifying income interest for life for which the state election was made. Paragraph (b) makes that the single carve-out from a rule with three conditions: apart from a § 2056(b) election, no federal election is allowable in computing the Minnesota tax “unless the estate is required to file a federal estate tax return, the election is made on the federal estate tax return, and the election is allowed under federal law.” The mechanics and the limits of that election — including that it defers Minnesota tax to the second death rather than creating a second $3,000,000 exclusion — are on the Minnesota estate tax page.

Four differences are worth stating plainly.

Who decides. The state-only QTIP election is the executor’s, made on Form M706. The disclaimer is the surviving spouse’s, made in a signed and acknowledged writing delivered to the personal representative or trustee.

When. Minn. Stat. § 289A.18, subd. 3 requires the estate tax return “within nine months after the decedent’s death,” and § 289A.19, subd. 4 extends the filing deadline by six months or by the length of the federal extension, whichever is longer. The nine months in § 2518(b)(2) has no extension of either kind. The two deadlines start on the same day and only one of them can be moved.

What it does to the property. The election leaves the property where the instrument put it and changes how the return treats it. The disclaimer changes who owns it — irrevocably, under § 524.2-1107(e).

What has to be in the documents. A Minnesota-only QTIP election needs qualifying property and a return. A disclaimer trust needs a provision drafted into the will or revocable trust before the first death, because for every interest § 524.2-1108 governs, paragraph (c) sends the disclaimed interest wherever that instrument says. For the interests § 524.2-1108(a) excepts — jointly held property under § 524.2-1109 and a trustee’s disclaimer under § 524.2-1110 — the instrument’s provision does not control at all.

What a disclaimer trust does not do

It does not change Minnesota’s exclusion, its rates, or its filing threshold. No form of the word “disclaim” appears anywhere in Minn. Stat. § 291.016, § 291.03, § 291.005, or § 289A.10 — all four sections were retrieved and searched in full for this page. The exclusion in § 291.016, subd. 3 stays $3,000,000 and the schedule in § 291.03, subd. 1(b) still starts at 13 percent. The filing test in § 289A.10, subd. 1 is unchanged too, and it is two tests under one precondition: for a decedent “who has an interest in property with a situs in Minnesota,” a return is required if either a federal estate tax return is required to be filed, or the federal gross estate plus three years of adjusted taxable gifts exceeds $3,000,000 for a 2020-or-later death. A surviving spouse’s disclaimer changes who takes the property; it does not remove anything from the first decedent’s gross estate, so the return that was required before the disclaimer is still required after it. The one situation in which a disclaimer does change a gross estate is the disclaimant’s own: 26 C.F.R. § 25.2518-1(b) provides that “the value of a decedent’s gross estate for purposes of the Federal estate tax does not include the value of property with respect to which the decedent, or the decedent’s executor or administrator on behalf of the decedent, has made a qualified disclaimer.” That is the point of the structure at the second death, and it is a different estate from the one filing this return.

It does not create portability. Portability is a federal mechanism that moves a dollar figure — the deceased spousal unused exclusion amount — from one spouse’s return to the other’s. A disclaimer moves property. Minnesota has no portability; § 291.016, subd. 3 was read in full and contains nothing that carries an exclusion from one spouse to the other, and the Department of Revenue has said so in a legislative analysis, both of which are documented on the Minnesota estate tax page. A disclaimer comes at the same problem from a different direction, by changing who takes the property at the first death. It does not supply the missing rule.

It does not work once the property has been accepted. Two independent provisions say so, and neither has an exception for a mistake made in good faith: § 2518(b)(3) federally and § 524.2-1106(b)(1) and (f) in Minnesota, the second of which makes a barred disclaimer “ineffective.”

It does nothing for a single person’s Minnesota estate tax. The structure exists to capture a first spouse’s unused exclusion, and an unmarried decedent has no first spouse. A single person can still make a qualified disclaimer — § 2518 is not limited to spouses — but § 2518(b)(4)(B) requires the property to pass to someone other than the disclaimant, and the spouse exception in (b)(4)(A) is unavailable by definition. The property leaves for good, to the next taker, with no trust in between unless the instrument built one.

What this page does not do

It sets out the Minnesota act, the federal statute, and the regulations as they read on the date at the top, and it identifies where they disagree with each other about timing. It does not tell any reader whether to disclaim, how much to disclaim, whether a particular will contains a usable disclaimer provision, or whether a bypass trust drafted in 2011 still says what its drafter meant. Those turn on the instrument, the assets, the survivor’s own finances, and federal income tax consequences — including the basis consequences of leaving property out of the second estate — that this page does not address at all.
