For 2026, the New York estate tax exemption is $7,350,000: estates at or below that value owe no New York estate tax.1Department of Taxation and Finance. Estate Tax Cross it, and a graduated tax climbing to 16% applies. Cross it by more than 5%, and a “cliff” rule taxes the entire estate from the first dollar. Those two features, plus the fact that New York does not let a surviving spouse inherit a deceased spouse’s unused exemption, are what make the state’s estate tax worth planning around well before death.
Who Has to File in 2026
An estate of a New York resident must file Form ET-706 if the federal gross estate plus any includible gifts exceeds $7,350,000.1Department of Taxation and Finance. Estate Tax The federal gross estate is a broad measure. It covers real estate, bank and investment accounts, retirement accounts, business interests, life insurance proceeds on policies the decedent owned or controlled, and personal property. Assets that pass outside probate count too, including jointly held property and payable-on-death accounts.
Nonresidents file if they owned real or tangible personal property physically located in New York and their worldwide federal gross estate exceeds the exclusion.1Department of Taxation and Finance. Estate Tax The filing test looks at the whole estate, not just the New York slice.
One difference from the federal system shapes almost every married couple’s plan: New York does not allow portability. If the first spouse to die does not use the full $7,350,000, the unused amount is gone. It cannot be shifted to the surviving spouse.
The Cliff at 105% of the Exemption
This is the feature that catches people. If a New York taxable estate exceeds 105% of the basic exclusion amount, the exemption disappears entirely. For 2026, that tipping point is $7,717,500. An estate of $7,350,000 owes nothing. An estate of $7,717,501 is taxed as if no exemption ever existed.
The jump is severe. An estate worth $7.4 million might owe roughly $6,500 on the $50,000 over the exemption. An estate worth $7.8 million, only $400,000 larger, could owe around $450,000 because the full estate now sits in the tax base. Executors and estate planners often call the zone between $7,350,000 and $7,717,500 a death trap: a modest change in asset values can produce an outsized bill.
For estates hovering near the cliff, charitable bequests, lifetime gifts made well in advance, and properly funded trusts can bring the taxable estate back under the line. After death, the options narrow sharply.
Rates Once You Owe
New York applies a graduated schedule with 15 brackets. Tax starts at 3.06% on the first $500,000 of taxable estate and reaches 16% on amounts above $10,100,000.2New York State Senate. New York Tax Law TAX 952 – Tax Imposed A few reference points along the schedule:
- Up to $500,000: 3.06%
- $500,000 to $1,000,000: $15,300 plus 5.0% of the excess
- $1,000,000 to $1,500,000: $40,300 plus 5.5% of the excess
- $5,100,000 to $6,100,000: $402,800 plus 12.0% of the excess
- $7,100,000 to $8,100,000: $650,800 plus 13.6% of the excess
- Over $10,100,000: $1,082,800 plus 16.0% of the excess
Once the cliff is triggered, these rates apply to the full New York taxable estate. Between the exemption and the cliff, only the excess is effectively taxed because a credit phases out liability on the sheltered portion. That phase-out is what creates the cliff itself.
What Counts, and What Comes Off
New York begins with the federal gross estate: every asset the decedent owned or held certain interests in at death, valued at fair market value as of the date of death. Executors may elect an alternate valuation date six months later if it produces a lower total.
From that gross estate, the executor subtracts allowable deductions: debts owed at death, funeral expenses, and administration costs such as legal fees, accounting fees, and executor commissions. The result, plus any includible gifts added back under the three-year rule, is the New York taxable estate.
Two deductions do most of the heavy lifting. Assets passing to a U.S. citizen spouse qualify for an unlimited marital deduction, so a $20 million estate left entirely to a citizen spouse owes no New York estate tax at the first death. Assets left to qualified charitable organizations are also fully deductible, with no ceiling; outright bequests and properly structured charitable remainder trusts both qualify. Executors should confirm the charity’s tax-exempt status before filing, because an outdated or revoked exemption voids the deduction.
A trap for people with property in multiple states: New York does not allow a deduction or credit for estate taxes paid to other states. If a vacation home sits in a state that also imposes estate tax, both states may tax the same asset. Some other states offer a reciprocal credit for New York tax paid; New York does not return the favor.
The Three-Year Gift Add-Back
New York does not impose its own gift tax. It does, however, pull certain lifetime gifts back into the taxable estate. Any taxable gift made during the three years before death must be added back for New York purposes.1Department of Taxation and Finance. Estate Tax A taxable gift is one exceeding the federal annual exclusion, which is $19,000 per recipient for 2026.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill
The exceptions are narrow. Gifts made while the decedent was a nonresident of New York, gifts made before April 1, 2014, and gifts of real or tangible property physically located outside New York are not added back.1Department of Taxation and Finance. Estate Tax
The practical point: gifting works only when made more than three years before death. A resident who gives $500,000 to a child and dies two years later has that gift added back. The same gift made four years before death stays out of the New York calculation. For estates near the exemption, this window makes timing decisive.
Married Couples and the Lost Exemption
Because there is no portability, a couple that relies only on the unlimited marital deduction wastes the first spouse’s $7,350,000 exemption. Everything passes to the survivor tax-free, and when the survivor dies, a single exemption shelters the combined estate. For a couple worth $14 million, that means roughly $7 million of taxable estate at the second death instead of zero.
The standard fix is a credit shelter trust, sometimes called a bypass trust. At the first death, assets up to the New York exemption fund the trust rather than passing outright to the survivor. The trust can provide income and access to the surviving spouse, but because trust assets are not part of the survivor’s estate, they pass to beneficiaries free of additional New York estate tax. Used correctly, this structure can shelter up to $14.7 million from New York estate tax for a couple in 2026.
Funding matters. Overfunding the trust past the New York exemption could trigger the cliff on the first spouse’s estate. Underfunding wastes exemption. And because New York’s exemption sits far below the federal exemption of $15,000,000 for 2026, trusts drafted only with federal numbers in mind can misfire under state rules.4Internal Revenue Service.

Nonresidents Who Own New York Property
A nonresident’s New York estate tax is calculated as if the decedent had been a resident, then prorated based on the ratio of New York-situs property to the total estate.5New York State Senate. New York Tax Law TAX 960 – Nonresidents Estate Tax
Only real and tangible personal property physically located in New York counts as New York property. Intangibles like stocks, bonds, and bank accounts are excluded from a nonresident’s New York taxable estate even if managed from within New York.5New York State Senate. New York Tax Law TAX 960 – Nonresidents Estate Tax The asset that most often triggers a nonresident filing is New York real estate, whether a co-op, vacation home, or commercial building.
Interests in entities that hold New York real estate are a gray area. Whether shares in a closely held corporation or LLC that owns New York property count as tangible or intangible depends on the entity structure and the facts. These situations need careful analysis.
How This Compares to Federal Estate Tax
The federal basic exclusion for 2026 is $15,000,000 per individual, following the One, Big, Beautiful Bill Act signed on July 4, 2025.4Internal Revenue Service. Whats New – Estate and Gift Tax A large number of New York estates will owe state tax but no federal tax. An estate of $12 million, for example, exceeds the New York threshold by nearly $5 million but sits well below the federal exemption.
The two taxes are calculated independently. You can owe one, the other, both, or neither. For estates above both thresholds, the combined marginal rate can exceed 50% when New York’s top 16% is added to the federal top rate of 40%.
Federal portability is worth flagging because New York has no equivalent. A surviving spouse can inherit the deceased spouse’s unused federal exclusion by filing Form 706 and electing portability, even if no federal tax is owed, so long as the election is made within five years of the first death. With the federal exclusion at $15 million, this can shelter up to $30 million from federal tax for a couple. Filing federally to preserve portability is almost always worth the effort, even when the estate is far below the federal threshold. None of this changes the New York calculation.
Filing Deadline, Extensions, and Penalties
Form ET-706 is due within nine months of the date of death.6Tax.NY.gov. Instructions for Form ET-706 New York State Estate Tax Return A copy of federal Form 706 must be filed with it, even if the estate is not required to file a federal return.1Department of Taxation and Finance. Estate Tax
Executors who need more time can request a six-month filing extension on Form ET-133.6Tax.NY.gov. Instructions for Form ET-706 New York State Estate Tax Return The extension applies only to filing. Tax remains due nine months after death, and interest accrues on any unpaid balance from that point. This is where executors most often stumble.
Late filing carries a penalty of 5% of the tax due for each month or partial month the return is overdue, up to 25%.7Department of Taxation and Finance. Interest and Penalties A separate late-payment penalty of 0.5% per month applies to unpaid tax. When both run, the filing penalty is reduced by the payment penalty amount, but the combined cost adds up quickly on a six-figure bill.
Unpaid New York estate tax also creates a lien on the decedent’s New York real property. That lien can block sales, refinancing, and transfers until the tax is resolved, which can freeze the estate’s most valuable asset at exactly the moment beneficiaries need liquidity.
