How does New York's estate tax exclusion cliff affect the estate?

This free New York estate tax calculator estimates the graduated tax and exclusion credit for a confirmed New York domiciliary at death. Include qualifying three-year taxable gift addbacks and allowable estate deductions. It preserves the $7.16 million exclusion for 2025 and $7.35 million for 2026, with a 2027 planning option explicitly using the provisional 2026 baseline. Nonresident and unresolved property-allocation or trust cases are blocked.

Year of death

New York domicile at death

Federal gross estate

Before estate deductions, at already determined estate-tax values.

Qualifying NY three-year taxable gift addback

Taxable gifts, not gross gifts; exclude gifts already in the estate and outside-NY real/tangible gifts.

NY-allowable outright marital deduction

NY-allowable charitable estate deduction

Other NY-allowable debts and expenses

Exclude NY estate tax itself and deductions entered above; federal income-tax deductions are not estate deductions.

Estate includes outside-NY real or tangible property

Triggers unsupported property/deduction allocation. Bank accounts and securities are intangible assets.

QTIP/trust adjustments, QDOT, pre-1930 powers, or special valuation/elections apply

How this calculation works

Uses the federal gross estate plus user-confirmed qualifying taxable gift addbacks, less entered NY-allowable marital, charitable, and other estate deductions.

Applies all 15 ET-706 graduated brackets with their exact base taxes, including 3.06% at the first bracket and 16% above $10,100,000.

Offsets the full tentative tax at or below exclusion. Inside the 5% band, applies the tax table to exclusion times one minus the four-decimal worksheet fraction.

The 2025 exclusion and 105% endpoint are $7,160,000 and $7,518,000; the 2026 amounts are $7,350,000 and $7,717,500.

Uses the current ET-706-I worksheet mechanics and NY Tax Law section 952 with the separately published 2026 exclusion. The current PDF still prints 2025 exclusion amounts; those are not used for 2026.

2027 indexed exclusion is not yet published in this calculator; its planning option uses $7,350,000 as a provisional 2026 baseline. Dollar outputs retain cents, not every whole-dollar return convention.

Common mistakes and caveats

Blocks nonresidents, uncertain domicile, outside-state real/tangible property and deduction allocation, QTIP/trust adjustments, noncitizen marital deductions, pre-1930 powers, and special valuation/election cases.

Gift addback is a supplied verified taxable-gift total, not an automatic audit of gift dates, valuations, domicile changes, or Form 709 records.

No federal portability, federal estate-tax calculation, recipient inheritance tax, recurring property tax, penalties, or payment balance is included.

The ET-706 filing threshold uses federal gross estate plus includible gifts before deductions. A required return may have zero estimated tax after deductions and exclusion credit.

The four-decimal credit worksheet can create small step changes near the exclusion and within the phaseout. The cliff is not a flat tax on just the amount above exclusion.

FAQ

What is New York's 2026 estate exclusion and cliff threshold?

The published 2026 basic exclusion is $7,350,000. At or below it, the credit offsets the calculated tax. The credit phases out above it and reaches zero at 105%, or $7,717,500. Above that threshold no exclusion credit is allowed.

Is the phaseout simply a percentage of the exclusion's tax credit?

No. ET-706-I first divides the amount above exclusion by 5% of exclusion, carries that fraction to four decimals, and computes a reduced credit base: exclusion times one minus the fraction. The graduated tax table is then applied to that reduced base to obtain the credit.

How much tax would a $7.5 million taxable estate owe in 2026?

With no extra adjustments, tentative tax is $705,200. The four-decimal worksheet fraction is 0.4082, the reduced credit base is $4,349,730, and the calculated credit is $318,769.76. Estimated tax after credit is $386,430.24, before whole-dollar filing rounding or payments.

Which gifts are added back?

Enter taxable gifts within three years ending at death, made while the decedent was a New York resident and not already in the federal gross estate. Exclude gifts of real or tangible property outside New York and the historical excluded periods listed by the state. Do not add every lifetime gift or add the same asset twice.

Can marital or charitable deductions avoid the cliff?

Allowable deductions can reduce the taxable estate and therefore change the credit stage. Enter only qualifying estate deductions. This tool does not assume QTIP elections or noncitizen-spouse QDOT eligibility, and New York estate tax itself must not be deducted in this state calculation.

Are nonresidents or out-of-state real property supported?

No. Only confirmed New York domiciliaries with no outside-New-York real or tangible property are supported. Nonresidents and deductions allocated to outside-state property require the ET-706 schedules. Securities and bank accounts are intangible property, not outside-state tangible assets.
