Introduction

New York imposes a throwback tax on distributions of accumulated trust income to New York resident beneficiaries—a regime enacted in 2014 to close a perceived loophole in the state’s resident trust exemption. For ultra-high-net-worth individuals (“UHNWIs”) who are beneficiaries of irrevocable, non-grantor trusts that qualify as exempt resident trusts under N.Y. Tax Law § 605(b)(3)(D), the throwback tax creates a latent New York State tax liability that can reach back decades. The controlling authority is N.Y. Tax Law § 612(b)(40), implemented through Form IT-205-J and Form IT-225. Unlike California’s regime, which traces to nonconformity with the federal repeal of throwback rules, New York’s throwback tax is a creature of state legislation enacted specifically to address the tax treatment of exempt resident trusts. The New York State Department of Taxation and Finance (NYS DTF) enforces the throwback tax, and the New York State Division of Tax Appeals (NY DTA) and New York State Tax Appeals Tribunal provide administrative review.

What Is the New York Throwback Tax?

Direct answer: The New York throwback tax is the tax imposed under N.Y. Tax Law § 612(b)(40) on a New York resident beneficiary who receives an accumulation distribution from an exempt resident trust. An exempt resident trust is one that meets all three conditions under N.Y. Tax Law § 605(b)(3)(D): all trustees are non-New York domiciliaries, all trust property is located outside New York, and all income is from non-New York sources.

Statutory Basis

Direct answer: The operative statute is N.Y. Tax Law § 612(b)(40), which requires a resident beneficiary receiving an accumulation distribution from an exempt resident trust to include that distribution in New York adjusted gross income. N.Y. Tax Law § 605(b)(3)(D) defines the exempt resident trust exclusion, and N.Y. Tax Law § 621 provides a credit for taxes paid by the trust.

N.Y. Tax Law § 612(b)(40) provides that a resident beneficiary’s New York adjusted gross income includes the accumulation distribution received from an exempt resident trust. N.Y. Tax Law § 605(b)(3)(D) defines an exempt resident trust as a resident trust that meets all three of the following conditions: (1) all trustees are domiciled in a state other than New York; (2) the entire corpus of the trust, including real and tangible personal property, is located outside New York State; and (3) all income and gains of the trust are derived from, or connected with, sources outside New York State . N.Y. Tax Law § 621 provides a credit against the throwback tax for taxes the trust paid to New York for prior taxable years . 20 NYCRR § 121.1 implements the credit provision, defining the “excess tax” that generates the credit .

Historical Development

Direct answer: New York enacted its throwback tax in 2014 through Part I of Chapter 59 of the Laws of 2014, effective for income accumulated in tax years beginning on or after January 1, 2014. The legislation was designed to close a loophole that allowed exempt resident trusts to accumulate income and distribute it to New York resident beneficiaries free of state income tax .

New York previously exempted from tax a resident trust if it had no trustees or assets located in New York and its income was not derived from New York sources—the exempt resident trust exception under N.Y. Tax Law § 605(b)(3)(D) . The 2014–2015 budget bill, signed by Governor Andrew Cuomo on April 1, 2014, closed this loophole in two ways. For incomplete gift non-grantor trusts (ING trusts), the New York resident grantor is taxed on the trust’s income. For all other exempt resident trusts, distributions of accumulated income are taxed to the New York resident beneficiaries who receive them . The throwback tax applies to income accumulated in tax years starting on or after January 1, 2014, with a transition exclusion for distributions made before June 1, 2014 .

Current Scope

Direct answer: The New York throwback tax applies to New York resident beneficiaries of exempt resident trusts, excluding distributions thrown back to tax years before January 1, 2014, tax years before the beneficiary became a New York resident, tax years before the beneficiary was born or reached age 21, and income already included in the beneficiary’s gross income.

The throwback tax applies when a New York resident beneficiary receives an accumulation distribution from an exempt resident trust. An accumulation distribution is defined as the excess of amounts properly paid, credited, or required to be distributed (other than income required to be distributed currently) over the distributable net income of the trust reduced by income required to be distributed currently . The tax does not apply to distributions from non-exempt resident trusts, because those trusts are subject to New York income tax on all of their income . Capital gains are generally excluded from the throwback tax unless they are part of federal distributable net income, such as where the trust is a foreign trust for federal income tax purposes .

Binding Effect and Legal Weight

Direct answer: N.Y. Tax Law § 612(b)(40) is primary statutory authority binding on the New York State Department of Taxation and Finance, all New York resident beneficiaries, and New York courts. Form IT-205-J instructions are secondary authority—persuasive in audits and appeals but not binding on courts. New York Tax Appeals Tribunal decisions are binding on the NYS DTF and the Division of Tax Appeals.

Who Is Bound

Direct answer: New York’s throwback tax statute binds the NYS DTF, all New York resident trust beneficiaries, and New York courts. The taxpayer bears the burden of proving that a throwback tax assessment is erroneous, and the NYS DTF’s determination is presumptively correct under New York law.

N.Y. Tax Law § 612(b)(40) binds the NYS DTF and all New York resident beneficiaries. The NYS DTF’s determination on audit is presumptively correct, and the taxpayer bears the burden of proof in administrative appeals. Form IT-205-J is the prescribed form for reporting accumulation distributions by exempt resident trusts, and Form IT-225 is used by beneficiaries to report the addition modification A-116 . The instructions to these forms provide guidance but do not have the force of law.

Precedential Value

Direct answer: New York Tax Appeals Tribunal decisions are binding on the NYS DTF and the Division of Tax Appeals but are persuasive only in New York courts. Tribunal decisions may be reviewed by the Appellate Division under N.Y. Tax Law § 2016.

The New York State Tax Appeals Tribunal issues decisions that are binding on the Division of Taxation and the Division of Tax Appeals, but the Tribunal’s decisions are subject to review by the Appellate Division under N.Y. Tax Law § 2016 . N.Y. Tax Law § 2016 provides that a decision of the Tax Appeals Tribunal shall be reviewable in accordance with the provisions of Article 78 of the CPLR . The Tribunal has established a firm policy of not allowing the submission of evidence after the record is closed, as stated in Matter of Wachsman .

Primary vs. Secondary Authority

Direct answer: N.Y. Tax Law § 612(b)(40) and § 605(b)(3)(D) are primary statutory authority. 20 NYCRR § 121.1 is primary regulatory authority. Form IT-205-J and Form IT-225 instructions are secondary authority. New York Tax Appeals Tribunal decisions are primary authority as administrative adjudications.

N.Y. Tax Law § 612(b)(40) and § 605(b)(3)(D) are the primary statutory authorities. 20 NYCRR § 121.1 is the primary regulatory authority implementing the credit for taxes paid by the trust . Form IT-205-J (New York State Accumulation Distribution for Exempt Resident Trusts) and Form IT-225 (New York State Modifications) are the prescribed forms, and their instructions constitute secondary authority. N.Y. Tax Law § 621 provides the statutory basis for the credit against the throwback tax .

Key Authorities and Cases

Direct answer: The controlling statutory authority for the New York throwback tax is N.Y. Tax Law § 612(b)(40), with the exempt resident trust definition in N.Y. Tax Law § 605(b)(3)(D) and the credit provision in N.Y. Tax Law § 621. Form IT-205-J provides the reporting framework. The New York State Bar Association Tax Section has commented extensively on the throwback tax proposal, identifying technical and constitutional issues.

New York Statutory Authority

N.Y. Tax Law § 612(b)(40) is the operative throwback tax provision. It requires a resident beneficiary’s New York adjusted gross income to include the accumulation distribution received from an exempt resident trust. N.Y. Tax Law § 605(b)(3)(D) defines an exempt resident trust as a resident trust meeting all three conditions: (1) all trustees are domiciled outside New York; (2) all trust property is located outside New York; and (3) all income and gains are from non-New York sources . N.Y. Tax Law § 621 provides a credit against the throwback tax for taxes the trust paid to New York for prior taxable years, preventing double taxation . N.Y. Tax Law § 612(b)(41) defines an incomplete gift non-grantor trust (ING trust) as a resident trust that does not qualify as a grantor trust and whose transfer is treated as an incomplete gift under IRC § 2511 .

New York Regulations and Guidance

20 NYCRR § 121.1 implements the credit provision under N.Y. Tax Law § 621 . It defines the excess tax as any amount of New York State personal income tax paid by the trust for a prior taxable year which would not have been payable if the trust had made a distribution to beneficiaries in the amount deemed to have been distributed under IRC § 666 . The credit is allowable only to the extent that the accumulation distribution is included in the New York adjusted gross income of the resident beneficiary . Form IT-205-J is filed by the exempt resident trust to report an accumulation distribution to a New York State resident beneficiary . The trust must provide resident beneficiaries with a copy of Part 4 of Form IT-205-J, which the beneficiary uses to complete addition modification A-116 on Form IT-225 . Form IT-205-C is the New York State Resident Trust Nontaxable Certification, which the trust files to certify exempt resident trust status .

Judicial and Tribunal Decisions

Published New York appellate decisions directly interpreting the modern throwback tax under N.Y. Tax Law § 612(b)(40) are limited because the provision was enacted in 2014. The New York State Tax Appeals Tribunal and the Division of Tax Appeals have jurisdiction to hear throwback tax appeals. The Tribunal’s decisions are reviewable by the Appellate Division under N.Y. Tax Law § 2016 and Article 78 of the CPLR . The New York State Bar Association Tax Section submitted comments on the Throwback Tax Proposal in March 2014, identifying a variety of technical, structural, and constitutional issues . The New York City Bar Association also submitted comments opposing the throwback tax and recommending simplified methods for computing it .

Practical Application in Tax Practice

Direct answer: In practice, New York throwback tax resolution requires the exempt resident trust to file Form IT-205-J to report the accumulation distribution, and the beneficiary to include the distribution in New York adjusted gross income using addition modification A-116 on Form IT-225. Practitioners must track undistributed net income (UNI) back to 1969 to determine the throwback years.

Research

Direct answer: Researching New York throwback tax requires consulting N.Y. Tax Law § 612(b)(40), § 605(b)(3)(D), and § 621, along with 20 NYCRR § 121.1 and the instructions to Form IT-205-J. Practitioners should also review the NYSBA Tax Section comments on the 2014 Throwback Tax Proposal and any Tax Appeals Tribunal decisions addressing the issue.

Start with N.Y. Tax Law § 612(b)(40) and § 605(b)(3)(D). Then consult 20 NYCRR § 121.1 for the credit computation and Form IT-205-J instructions for the trust’s reporting obligations. The NYSBA Tax Section comments on the Throwback Tax Proposal provide extensive analysis of the technical and constitutional issues . Practitioners should also review N.Y. Tax Law § 612(b)(41) for the ING trust definition, as ING trusts are subject to a different regime (taxation to the grantor rather than the beneficiary) .

Audit

Direct answer: A New York throwback tax audit typically arises when the NYS DTF identifies an accumulation distribution reported on Form IT-205-J or through matching with beneficiary returns. The NYS DTF will request trust documents, Form IT-205-J filings, and evidence of the beneficiary’s residency and the trust’s exempt status during each accumulation year.

The NYS DTF may initiate a throwback tax examination when an exempt resident trust files Form IT-205-J reporting an accumulation distribution, or when the NYS DTF identifies a distribution from a trust with New York beneficiary connections. The trust must file Form IT-205-C to certify exempt resident trust status . The taxpayer bears the burden of substantiating the character and amount of the distribution and the beneficiary’s residency status during the accumulation period. Form IT-205-J requires the trust to track undistributed net income (UNI) by throwback year, potentially going back to 1969 to determine the existence of prior years’ undistributable net income .

Appeals

Direct answer: A taxpayer may appeal a NYS DTF throwback tax determination by filing a Petition with the New York State Division of Tax Appeals. The petition must be filed within 90 days of the Notice of Deficiency. The Administrative Law Judge issues a determination, which may be appealed to the Tax Appeals Tribunal under N.Y. Tax Law § 2006.

The NYS DTF’s audit process results in a Notice of Deficiency if additional tax is due. The taxpayer may protest the determination by filing a Petition with the Division of Tax Appeals under 20 NYCRR § 3000.3. The Administrative Law Judge issues a determination, which may be appealed to the Tax Appeals Tribunal under N.Y. Tax Law § 2006. The Tribunal’s decision is reviewable by the Appellate Division under N.Y. Tax Law § 2016 and Article 78 of the CPLR . A request for a BCMS conciliation conference or a petition for a hearing before the Division of Tax Appeals must be filed within two years from the date on which the refund request was deemed denied, as stated in Matter of Janet Yoell-Mirel .

Litigation

Direct answer: Tax Appeals Tribunal decisions may be reviewed by the New York Appellate Division under N.Y. Tax Law § 2016 in accordance with Article 78 of the CPLR. The Appellate Division reviews the Tribunal’s decision on the administrative record. Questions of law are reviewed de novo.

Judicial review of Tribunal decisions is governed by N.Y. Tax Law § 2016, which provides that a decision of the Tax Appeals Tribunal shall be reviewable in accordance with the provisions of Article 78 of the CPLR . The Tax Law directs the petitioner to designate the Tax Appeals Tribunal and the Commissioner of Taxation and Finance as respondents to the proceeding for judicial review . The Appellate Division reviews the Tribunal’s findings for substantial evidence and its legal conclusions for errors of law.

Planning Strategies

Direct answer: UHNWI trust beneficiaries should consider four primary planning strategies to manage New York throwback tax exposure: (1) avoiding accumulation distributions while a New York resident; (2) making distributions to non-New York beneficiaries; (3) minimizing UNI by structuring trust investments to generate capital gains rather than ordinary income; and (4) documenting a genuine change of residency before distribution.

Key planning strategies include: (1) Avoid triggering accumulation distributions while the beneficiary is a New York resident, since the throwback tax applies upon distribution. (2) Make distributions to non-New York beneficiaries where trust terms permit, as the throwback tax applies only to New York resident beneficiaries. (3) Minimize undistributed net income (UNI) by structuring trust investments to generate capital gains rather than ordinary income, because capital gains are generally not included in distributive net income (DNI) and therefore do not become subject to the throwback rule when distributed . (4) Document a genuine change of residency before any planned distribution to avoid the throwback tax. (5) Consider the ING trust rules, as ING trusts are taxed to the grantor rather than the beneficiary, which may provide planning opportunities . (6) Utilize the credit under N.Y. Tax Law § 621 for taxes paid by the trust to New York, which prevents double taxation of the same income .

Interaction with Other Authorities

Direct answer: N.Y. Tax Law § 612(b)(40) controls over inconsistent NYS DTF guidance and form instructions. Federal tax law is relevant to the extent New York conforms to specific IRC provisions, particularly the definition of accumulation distribution under IRC § 665 and the distribution rules under IRC § 666. The U.S. Constitution limits New York’s throwback tax under the Due Process Clause.

Higher Authority

Direct answer: The U.S. Constitution is the highest authority, followed by the New York Constitution and N.Y. Tax Law. The Due Process Clause requires a minimum connection between New York and the beneficiary before New York may impose the throwback tax. New York’s throwback tax applies to resident beneficiaries, which satisfies due process minimum contacts.

Under the Due Process Clause, New York may tax a beneficiary only if the beneficiary has sufficient minimum contacts with the state. Because the throwback tax applies to New York resident beneficiaries, the residency itself establishes the requisite connection. The Commerce Clause is less directly applicable to individual income tax residency than to business taxation. The NYSBA Tax Section raised constitutional concerns about the Throwback Tax Proposal, noting that certain issues should be addressed before the proposal became effective .

Lower Authority

Direct answer: Form IT-205-J instructions, NYS DTF publications, and advisory opinions are lower authority than N.Y. Tax Law § 612(b)(40). Form instructions provide guidance but do not have the force of law. The NYS DTF’s interpretation of the throwback tax is entitled to deference but is subject to judicial review.

Form IT-205-J instructions and Form IT-225 instructions are secondary authority. Form IT-205-C (New York State Resident Trust Nontaxable Certification) is the prescribed form for certifying exempt resident trust status . NYS DTF advisory opinions and TSB-Ms provide agency interpretation but are not binding on courts. The NYS DTF has not permitted trusts to use a simplified “default calculation” similar to that employed by the IRS in Part III of Form 3520 for throwback purposes .

Conflict Resolution

Direct answer: When NYS DTF form instructions conflict with N.Y. Tax Law § 612(b)(40), the statute controls. When a Tax Appeals Tribunal decision conflicts with an NYS DTF advisory opinion, the Tribunal decision is binding on the NYS DTF and the Division of Tax Appeals. When a New York court decision conflicts with a Tribunal decision, the court decision controls.

The resolution rule is that legislative enactments supersede administrative rules and guidance. N.Y. Tax Law § 612(b)(40) controls over any inconsistent form instruction or publication. Tax Appeals Tribunal decisions are binding on the NYS DTF and the Division of Tax Appeals . New York court decisions interpreting § 612(b)(40) are binding on all parties. The Appellate Division reviews Tribunal decisions under Article 78 of the CPLR .

Sunset and Transition Rules

Direct answer: New York’s throwback tax under N.Y. Tax Law § 612(b)(40) has no scheduled sunset. The provision was enacted in 2014 and applies to income accumulated in tax years beginning on or after January 1, 2014. A transition exclusion applies to distributions made before June 1, 2014.

New York’s throwback tax regime has no sunset provision. The provision was enacted by Part I of Chapter 59 of the Laws of 2014, signed by Governor Andrew Cuomo on April 1, 2014 . The throwback tax applies to income accumulated by a trust in a tax year starting on or after January 1, 2014. A transition exclusion applies to distributions by exempt resident trusts (except ING trusts) of accumulated income made before June 1, 2014, and to income earned by ING trusts that are liquidated on or before June 1, 2014 . No pending legislation is scheduled to repeal or modify § 612(b)(40) as of October 5, 2026.

Common Errors and Pitfalls

1. Assuming the throwback tax applies to all trust distributions. The throwback tax applies only to accumulation distributions from exempt resident trusts. Distributions from non-exempt resident trusts are not subject to the throwback tax because those trusts are taxed on all of their income at the trust level .
2. Failing to track undistributed net income (UNI) by throwback year. The throwback tax computation requires tracking UNI back to 1969 to determine the existence of prior years’ undistributable net income to which certain distributions could be applied. Practitioners who fail to maintain year-by-year UNI records cannot accurately compute the throwback tax .
3. Ignoring the exclusion for pre-2014 accumulations. Accumulation distributions thrown back to tax years before January 1, 2014 are excluded from the throwback tax. This is a critical transition rule that practitioners must apply correctly .
4. Overlooking the age-21 and pre-residency exclusions. New York law excludes from the throwback tax accumulation distributions thrown back to tax years before the beneficiary was born or reached age 21, or before the beneficiary first became a New York State resident . These exclusions are unique to New York and are not present in California’s regime.
5. Failing to claim the credit for taxes paid by the trust. New York resident beneficiaries are entitled to a credit under N.Y. Tax Law § 621 and 20 NYCRR § 121.1 for taxes the trust paid to New York for prior taxable years, preventing double taxation . Overlooking this credit results in overpayment.
6. Treating capital gains as subject to the throwback tax. Capital gains are generally excluded from the throwback tax unless they are part of federal distributable net income, such as where the trust is a foreign trust for federal income tax purposes . Mischaracterizing capital gains as ordinary income can lead to overreporting.
7. Failing to coordinate Form IT-205-J and Form IT-225 reporting. The trust must file Form IT-205-J and provide resident beneficiaries with Part 4 of the form. The beneficiary then uses Part 4 to complete addition modification A-116 on Form IT-225 . Compliance gaps arise when the trust and beneficiary fail to coordinate.
8. Assuming ING trusts are subject to the beneficiary-level throwback tax. Incomplete gift non-grantor trusts (ING trusts) are taxed to the grantor under N.Y. Tax Law § 612(b)(41), not to the beneficiary. Practitioners must distinguish ING trusts from other exempt resident trusts .

What This Article Does Not Cover

• California throwback tax. California maintains a separate throwback tax regime under Cal. Rev. & Tax. Code § 17745(b). California tax law is beyond the scope of this New York-focused article.
• Federal throwback rules. The federal throwback rules under IRC §§ 665–668 were repealed for domestic trusts in 1997. They remain in effect for foreign trusts. This article addresses only the New York regime.
• Grantor trust taxation. When a trust is a grantor trust for New York purposes, income is taxed to the grantor, and the throwback tax does not apply. Grantor trust rules are addressed only as they relate to throwback tax applicability.
• New York City personal income tax. New York City imposes its own personal income tax on residents under N.Y. Admin. Code § 11-1701, and a credit for accumulation distributions is available under N.Y. Tax Law § 1310 . City-level taxation is beyond the scope of this article.
• Estate and gift tax consequences. The throwback tax is an income tax provision. Federal and New York estate and gift tax consequences of trust distributions are separate matters.
• Non-New York beneficiary taxation. Beneficiaries who are not New York residents at the time of distribution are generally outside the scope of the New York throwback tax.
• Criminal tax evasion. This article addresses civil throwback tax compliance and controversy, not criminal investigations under N.Y. Tax Law § 1801.

Frequently Asked Questions

What is the New York throwback tax?

Direct answer: The New York throwback tax is a state income tax imposed under N.Y. Tax Law § 612(b)(40) on New York resident beneficiaries who receive accumulation distributions from exempt resident trusts. The tax was enacted in 2014 to close a loophole that allowed exempt resident trusts to accumulate income and distribute it to New York resident beneficiaries free of state income tax.

What is an exempt resident trust?

Direct answer: An exempt resident trust is a resident trust that meets all three conditions under N.Y. Tax Law § 605(b)(3)(D): (1) all trustees are domiciled in a state other than New York; (2) the entire corpus of the trust, including real and tangible personal property, is located outside New York State; and (3) all income and gains of the trust are derived from sources outside New York State. An exempt resident trust is not subject to New York State income tax at the trust level.

Does New York follow the federal repeal of throwback rules?

Direct answer: No. New York enacted its own throwback tax in 2014 through Part I of Chapter 59 of the Laws of 2014, independent of the federal repeal of throwback rules for domestic trusts under the Taxpayer Relief Act of 1997. The New York throwback tax applies to accumulation distributions from exempt resident trusts to New York resident beneficiaries.

How is the New York throwback tax calculated?

Direct answer: The New York throwback tax is calculated on Form IT-205-J by tracking undistributed net income (UNI) by throwback year, potentially going back to 1969. The trust reports the accumulation distribution, and the beneficiary includes it in New York adjusted gross income using addition modification A-116 on Form IT-225. A credit is available under N.Y. Tax Law § 621 for taxes the trust paid to New York.

Can a beneficiary avoid the throwback tax by changing residency?

Direct answer: A beneficiary who is not a New York resident at the time of distribution is generally outside the scope of the New York throwback tax. The tax applies only to New York resident beneficiaries who receive accumulation distributions from exempt resident trusts. Additionally, accumulation distributions thrown back to tax years before the beneficiary first became a New York resident are excluded from the throwback tax.

What forms are required for the New York throwback tax?

Direct answer: The exempt resident trust files Form IT-205-J (New York State Accumulation Distribution for Exempt Resident Trusts) with Form IT-205 and Form IT-205-C (New York State Resident Trust Nontaxable Certification). The trust provides resident beneficiaries with Part 4 of Form IT-205-J. The beneficiary uses Part 4 to complete addition modification A-116 on Form IT-225 (New York State Modifications).

Conclusion

The New York throwback tax under N.Y. Tax Law § 612(b)(40) is a significant and often overlooked exposure for UHNWI trust beneficiaries. Enacted in 2014 to close a perceived loophole in the exempt resident trust exception under N.Y. Tax Law § 605(b)(3)(D), the throwback tax taxes accumulation distributions to New York resident beneficiaries at the rates in effect in the year of distribution. The controlling authorities are state-specific: N.Y. Tax Law § 612(b)(40), Form IT-205-J, and Form IT-225. Unlike California’s regime, which traces to nonconformity with federal law, New York’s throwback tax is a deliberate legislative creation with its own exclusions and credit mechanisms. Resolution requires careful documentation of the beneficiary’s residency status, the trust’s exempt status during each accumulation year, and accurate computation of undistributed net income. UHNWIs and their advisers should proactively model throwback tax exposure and consider distribution timing and residency planning well in advance of any accumulation distribution.
