Ultra-Millionaire Tax Act of 2026

This Act may be cited as the Ultra-Millionaire Tax Act of 2026.
The Internal Revenue Code of 1986 is amended by inserting after subtitle B the following new subtitle:
In the case of an individual, a tax is hereby imposed on the net value of all taxable assets of the taxpayer on the last day of any calendar year.
The tax imposed by this section shall be equal to the sum of—
0 percent of so much of the net value of all taxable assets of the taxpayer as does not exceed the zero bracket threshold,
2 percent of so much of the net value of all taxable assets of the taxpayer in excess of the zero bracket threshold but not in excess of the top bracket threshold, plus
the applicable percentage of so much of the net value of all such taxable assets of the taxpayer in excess of the top bracket threshold.
For purposes of this section—
The zero bracket threshold is $50,000,000.
The top bracket threshold is $1,000,000,000.
For purposes of this section, the applicable percentage is—
except as provided in subparagraph (B), 3 percent, and
in the case of any calendar year in which there is in effect legislation which meets the requirements of paragraph (2), 6 percent.
Legislation meets the requirements of this paragraph if such legislation—
establishes a health insurance program that provides to all residents of the United States comprehensive protection against the costs of health care and health-related services, and
prohibits private entities from providing duplicate benefits.
For purposes of this section, individuals who are married (as defined in section 7703) shall be treated as one taxpayer.
Any trust or portion of a trust which is a nongrantor multibeneficiary trust shall be treated as an individual to whom this chapter applies.
In applying this chapter to a nongrantor multibeneficiary trust—
the zero bracket threshold shall be equal to the sum of—
$0, plus
the lowest unused 0 percent bracket amount assigned to the trust by all beneficiaries of the trust, and
the top bracket threshold shall be equal to the sum of—
$0, plus
the lowest unused 2 percent bracket amount assigned to the trust by all beneficiaries of the trust.
For purposes of this paragraph, the term unused 0 percent bracket amount means, with respect to any beneficiary for any calendar year, the lesser of—
the excess (if any) of—
the zero bracket threshold, over
the sum of—
the net value of all taxable assets of the beneficiary for the calendar year, plus
any unused 0 percent bracket amount assigned by the beneficiary to other nongrantor multibeneficiary trusts, or
the portion of the net value of all taxable assets of the trust which such beneficiary is eligible to receive.
For purposes of this paragraph, the term unused 2 percent bracket amount means, with respect to any beneficiary for any calendar year, the lesser of—
the excess (if any) of—
the top bracket threshold reduced by the zero bracket threshold, over
the sum of—
the net value of all taxable assets of the beneficiary for the calendar year in excess of the zero bracket threshold, plus
any unused 2 percent bracket amount assigned by the beneficiary to other nongrantor multibeneficiary trusts, or
the portion of the net value of all taxable assets of the trust which such beneficiary is eligible to receive.
The assignment of any amount of unused 0 percent bracket amount and unused 2 percent bracket amount shall be made at such time and in such manner as specified by the Secretary in regulations. In any case in which no affirmative assignment is made by a beneficiary, the amount assigned shall be $0.
For purposes of this chapter—
The term nongrantor multibeneficiary trust means any trust or portion of a trust—
with respect to which no person is treated as an owner under subpart E of subchapter J of chapter 1,
no property of which is attributable to a gratuitous transfer of assets by a person who is subject to tax under this chapter for the calendar year, and
which has more than one beneficiary (determined as of the last day of the calendar year).
Such term shall not include—
any trust described in section 401(a) and exempt from tax under section 501(a),
any trust all of the unexpired interests in which are devoted to one or more of the purposes described in section 170(c)(2)(B),
any charitable lead annuity trust (as defined in section 2642(e)(3)) or charitable lead unitrust, or
any charitable annuity remainder trust (as defined in section 664(d)(1)) or any charitable remainder unitrust (as defined in section 664(d)(2)).
The term beneficiary shall not include any person whose interest in a trust is contingent on the death of another person with an interest in such trust.
For purposes of this subtitle, the term net value of all taxable assets means, as of any date, the value of all property of the taxpayer (other than property excluded under subsection (b)), real or personal, tangible or intangible, wherever situated, reduced by any debts (including any debts secured by property excluded under subsection (b)) owed by the taxpayer.
Property of the taxpayer shall not be taken into account under subsection (a) if such property—
has a value of $50,000 or less (determined without regard to any debt owed by the taxpayer with respect to such property),
is tangible personal property, and
is not property—
which is used in a trade or business of the taxpayer,
in connection with which a deduction is allowable under section 212, or
which is a collectible as defined in section 408(m), a boat, an aircraft, a mobile home, a trailer, a vehicle, or an antique or other asset that maintains or increases its value over time (within the meaning of section 5.02(2) of Revenue Procedure 2018–08).
For purposes of this subtitle—
Any property that would be included in the estate of the taxpayer if the taxpayer died shall be treated as property of the taxpayer.
Any property transferred by the taxpayer after the date of the enactment of this chapter, to an individual who is a member of the family of the taxpayer (as determined under section 267(c)(4)) and has not attained the age of 18 shall be treated as property of the taxpayer for any calendar year before the year in which such individual attains the age of 18.
If an individual is treated as the owner of any portion of a trust under subpart E of subchapter J of chapter 1, property attributable to such trust or portion of the trust shall be treated as property of the individual and not as property of the trust.
In the case of a trust or portion of a trust which is not described in subparagraph (A), any property which is attributable to a gratuitous transfer of assets by an individual who is subject to tax under this chapter for the calendar year shall be treated as property of such individual and not as property of the trust.
In the case of any trust or portion of a trust which is described in subclause (II), the property of such trust shall be treated as the property of the beneficiary of such trust and not as the property of the trust.
A trust is described in this subclause if such trust not described in subparagraph (A), the assets of such trust are not attributable to a gratuitous transfer of assets by a person who is subject to tax under this chapter for the calendar year, and such trust has a single beneficiary (determined as of the last day of the calendar year).
If any part of the net value of taxable assets of an individual on which tax has been paid consists of the value of property held by a trust which is included in the net value of taxable assets of such individual by reason of subparagraph (B), then such individual shall be entitled to recover from the trust the amount which bears the same ratio to the recoverable amount as—
the value of such property, bears to
the net value of taxable assets of the taxpayer.
For purposes of clause (i), the recoverable amount with respect to any trust is the excess of—
the tax imposed under this chapter for the calendar year on the individual, over
the amount of such tax which would be imposed for such calendar year on such individual if no property held by such trust were included in the net value of taxable assets of the individual.
In any case where a trust does not reimburse any taxpayer as provided in clause (i), the taxpayer shall be treated for purposes of this chapter as having made a gratuitous transfer to the trust in an amount equal to the amount determined under clause (i). Such transfer shall be treated as having been made on the last day of the calendar year for which the tax under subsection (a) was due.
In the case of any charitable remainder annuity trust (as defined in section 664(d)(1)) or of a charitable remainder unitrust (as defined in section 664(d)(2))—
the present value of any remainder interest shall not be taken into account under subsection (a), and
the present value of any other interests shall be taken in account under subsection (a), in accordance with regulations promulgated by the Secretary, as the property of the beneficiaries of such interests.
In the case of a charitable lead annuity trust (as defined in section 2642(e)(3)) or a charitable lead unitrust—
the present value of any interest described in section 2522(c)(2)(B) shall not be taken into account under subsection (a), and
notwithstanding paragraphs (A) and (B) of paragraph (3), the present value of any remainder interest shall be taken into account under subsection (a), in accordance with regulations promulgated by the Secretary, as the property of the beneficiaries of such remainder interest.
Not later than 12 months after the date of the enactment of this section, the Secretary shall establish rules and methods for determining the value of any asset for purposes of this subtitle, including rules for the valuation of assets that are not publicly traded or that do not have a readily ascertainable value. Such rules and methods—
may utilize retrospective and prospective formulaic valuation methods not currently in use by the Secretary,
may require the use of formulaic valuation approaches for designated assets, including formulaic approaches based on proxies for determining presumptive valuations, formulaic approaches based on prospective adjustments from purchase prices or other prior events, or formulaic approaches based on retrospectively adding deferral charges based on eventual sale prices or other specified later events indicative of valuation, and
may address the use of valuation discounts.
In the case of any individual who dies during a calendar year and who is not married on the date of such individual's death—
section 2901(a) shall be applied by substituting the date of the individual's death for the last day of the calendar year, and
the amount of the tax imposed under such section shall be reduced by an amount which bears the same ratio to such amount (determined without regard to this subsection) as—
the number of days in the calendar year after the date of the individual's death, bears to
365.
For purposes of section 2053, the tax imposed by this section for the year of the decedent's death shall be considered to have been imposed before such death.
In the case of any individual who is a non-resident and not a citizen of the United States, this subtitle shall apply only to the property of such individual which is situated in the United States (determined under rules similar to the rules under subchapter B of chapter 11).
In the case of an individual who is a covered expatriate (as defined in section 877A), section 2901(a) shall be applied—
as if the calendar year ended on the day before the expatriation, and
as if the rate of tax under both subparagraphs (A) and (B) of section 2901(b)(1) were 40 percent.
Not later than 12 months after the date of the enactment of this section, the Secretary shall by regulations require the reporting of any information concerning the net value of assets appropriate to enforce the tax imposed by this chapter.
The Secretary shall, where appropriate, require the reporting made under subsection (a) to be made as a part of existing income reporting requirements (including requirements under chapter 4 (relating to taxes to enforce reporting on certain foreign accounts)).
The Secretary may impose reporting obligations by reference to the ownership, control, management, claim to income from, or other relationship to assets and liabilities for purposes of administering the tax imposed by this section and may impose such obligations on financial institutions, business entities, or other persons, including requiring business entities to provide estimates of the value of the entity itself.
The Secretary shall annually audit not less than 30 percent of taxpayers required to pay the tax imposed under this chapter.
Section 275 of the Internal Revenue Code of 1986 is amended by inserting after paragraph (6) the following new paragraph:
Taxes imposed by chapter 18.
Section 6161(a) of the Internal Revenue Code of 1986 is amended by adding at the end the following new paragraph:
In the case of taxpayer described in subparagraph (B), the Secretary may extend the time for payment of the tax imposed under chapter 18 for a reasonable period not to exceed 5 years from the date fixed for the payment thereof.
A taxpayer is described in this subparagraph if such the Secretary determines—
the taxpayer has severe liquidity constraints, or
immediate payment would cause undue hardship on an ongoing enterprise.
Not later than 12 months after the date of the enactment of this Act, the Secretary of the Treasury (or the Secretary's delegate) shall establish rules for the application of the amendments made by paragraph (1).
Section 6662(b) of the Internal Revenue Code of 1986 is amended by adding at the end the following new paragraph:
Any substantial wealth tax valuation understatement.
Section 6662 of such Code is amended by adding at the end the following new subsection:
For purposes of this section, there is a substantial wealth tax valuation understatement if the value of any property claimed on any return of tax imposed by subtitle B–1 is 65 percent or less of the amount determined to be the correct amount of such valuation.
No penalty shall be imposed by reason of subsection (b)(11) unless the portion of the underpayment attributable to substantial wealth tax valuation understatements for the calendar year exceeds $5,000.
In the case of any portion of an underpayment which is attributable to one or more substantial wealth tax valuation understatement, subsection (a) shall be applied—
in the case of a substantial wealth tax valuation understatement which is a gross wealth tax valuation misstatement, by substituting 50 percent for 20 percent, and
in any other case, by substituting 30 percent for 20 percent.
For purposes of subparagraph (A), the term gross wealth tax valuation misstatement means a substantial wealth tax valuation understatement, as determined under paragraph (1) by substituting 40 percent for 65 percent.

The amendments made by this section shall apply to calendar years beginning after December 31, 2026.

The Secretary of the Treasury (or the Secretary's delegate) may issue such rules and regulations as necessary to prevent taxpayers from avoiding the purpose of information reporting requirements under the Internal Revenue Code of 1986 by placing assets in any foreign corporation, partnership, or trust in which the taxpayer holds directly or indirectly, a significant interest as the sole or principal owner or the sole or principal beneficial owner.
The Secretary of the Treasury (or the Secretary's delegate) shall develop a comprehensive plan for managing efforts to leverage data collected under chapter 4 of the Internal Revenue Code of 1986 in agency compliance efforts. Such plan shall include an evaluation of the extent to which actions being undertaken as of the date of the enactment of this Act for the enforcement of the requirements of such chapter improve voluntary compliance and address noncompliance with such requirements.
