New York Estate
Tax Calculator

New York imposes a state estate tax with an exemption of **$7.16 million**, indexed for inflation. However, New York's estate tax is infamous for its cliff: if the taxable estate exceeds 105% of the exemption amount (roughly $7.29 million for 2025), the entire exemption is eliminated and the full estate is taxed.

Rates range from 3.06% to 16%.

This 105% cliff is the most punishing feature in any state's estate tax system. An estate worth $7.28 million pays zero New York estate tax.

An estate worth $7.30 million pays tax on the entire $7.30 million — approximately $452,000. The cliff creates a discontinuity that demands precision in estate valuation and planning.

New York's exemption of **$7.16 million** is roughly half the federal exemption. Estates between these thresholds face state but not federal estate tax.

New York does not allow portability of its state exemption between spouses. Combined with the cliff effect, this makes New York one of the most treacherous jurisdictions for estate tax planning.

New York also does not impose a gift tax, creating an asymmetry worth noting: lifetime gifts reduce the New York taxable estate but are not clawed back for state tax purposes (unlike federal gift tax, which brings taxable gifts back into the estate). However, gifts made within three years of death are added back to the New York taxable estate, so timing is critical.

The three-year clawback for lifetime gifts is a major planning consideration. Gifts to irrevocable trusts must survive the three-year window to remain outside the New York taxable estate.

Begin gifting programs well in advance of anticipated mortality.

Domicile is a perennial issue in New York. The state aggressively audits domicile claims, particularly for high-net-worth individuals who split time between New York and a no-income-tax state.

A New York domicile determination subjects the entire worldwide estate to New York estate tax. The 183-day safe harbor for income tax purposes does not apply to estate tax domicile, which is based on intent.

Maintaining contemporaneous domicile documentation is essential.

New York residents with taxable estates face a two-layer system: the federal estate tax (exemption of $15 million in 2025, top rate of 40%) and the New York estate tax (exemption of $7.16 million). The gap between these exemptions creates a range where only the state tax applies.

An estate valued at $8 million, for example, may owe New York estate tax while owing nothing at the federal level.

The federal return (Form 706) allows a deduction for state estate taxes paid, which partially offsets the double-taxation effect but does not eliminate it. The state tax is deductible on the federal return as an estate administration expense or under the state death tax credit rules, depending on the estate's circumstances.

The net result is that combined effective rates in New York can exceed 45% on estates large enough to trigger both layers.

Planning for this interaction requires modeling both taxes simultaneously. Strategies that reduce the New York taxable estate — such as lifetime gifts, charitable bequests, and irrevocable trusts — may also reduce federal exposure, but the relative benefit depends on where the estate falls within each jurisdiction's rate brackets.

Use our New York estate tax calculator to model both layers side by side, and check the New York probate cost calculator to estimate administration expenses.

Federal law permits a surviving spouse to use the deceased spouse's unused exclusion (DSUE) — commonly called portability — by timely filing Form 706 for the first-to-die spouse. This allows married couples to shelter up to $30 million federally without trust-based planning.

However, most estate-tax states, including New York, do not offer portability of the state exemption.

This asymmetry makes bypass trusts (also called credit shelter trusts or B trusts) essential in New York. At the first spouse's death, funding a bypass trust up to the New York exemption amount preserves that exemption for state tax purposes.

Without the trust, the unlimited marital deduction passes everything to the surviving spouse tax-free at the first death — but the surviving spouse's estate then has only one New York exemption, effectively wasting the first spouse's.

The bypass trust should be sized carefully. Overfunding it beyond the New York exemption wastes the marital deduction benefit; underfunding it fails to capture the full state exemption.

For married couples with estates above $7.16 million but below $15 million, the bypass trust is the single most impactful planning tool available. Review your plan with the New York estate tax estimator, and use the executor fee calculator to account for administration costs in your projections.

The $7.16 million New York exemption establishes a lower threshold than the federal exemption, making proactive estate reduction strategies more urgent. Irrevocable trusts are the primary vehicle: irrevocable life insurance trusts (ILITs) remove life insurance proceeds from the taxable estate, spousal lifetime access trusts (SLATs) allow married couples to remove assets while retaining indirect access, and qualified personal residence trusts (QPRTs) transfer a home at a discounted gift tax value.

Annual exclusion gifting — currently $19,000 per recipient (2025) — reduces the taxable estate dollar-for-dollar without consuming the lifetime gift exemption. For New York residents near the $7.16 million threshold, a sustained gifting program over several years can bring the estate below the state exemption entirely.

Charitable remainder trusts (CRTs) and charitable lead trusts (CLTs) offer additional reduction while generating income tax deductions.

GRATs (grantor retained annuity trusts) are particularly effective in low-interest-rate environments, transferring asset appreciation to beneficiaries with minimal or zero gift tax cost. For New York business owners, entity-level planning — family limited partnerships, LLCs with valuation discounts, and buy-sell agreements — can reduce the reportable value of closely held interests for both state and federal purposes.
