What is the New York estate tax cliff?

When a NY taxable estate exceeds 105% of the NY basic exclusion amount (105% × $7,160,000 = $7,518,000 in 2025), the entire exclusion credit is eliminated. Instead of getting a credit equal to the tax on $7.16M, the estate gets zero credit — the full estate is taxed from the first dollar. This creates a cliff: an estate of $7.52M pays roughly the same NY tax as an estate worth $50M. The phase-out zone is narrow: the credit phases out linearly between 100% and 105% of the exclusion.

Why does NY have no estate tax portability?

Federal law allows a surviving spouse to use the deceased spouse's unused federal exclusion (portability). New York does not have this provision — each spouse has only their own $7.16M NY exclusion. For married couples with combined estates above $7.16M, this makes estate planning with AB trusts or credit shelter trusts essential. Without planning, the first spouse's exclusion is often wasted if assets pass outright to the survivor.

What are NY estate tax rates?

NY estate tax rates range from 3.06% to 16%. The rate schedule is graduated, starting at 3.06% on the first $500,000 of taxable estate and reaching 16% on amounts above $10.1 million. Because the exclusion credit is based on the tax that would be owed on a $7.16M estate, effective rates for estates above the exclusion can feel very high — especially near the cliff threshold where you lose the full credit on a modest incremental increase.

How does the marital deduction interact with the NY cliff?

Assets passing to a US-citizen spouse are excluded from the NY taxable estate. For estates near the cliff, the marital deduction can be used strategically to reduce the taxable estate below 105% of the exclusion, avoiding the cliff entirely. However, this defers (not eliminates) the tax — the combined estate in the survivor's hands may face the cliff at that point. A qualified terminable interest property (QTIP) trust can help manage this.

Is the NY estate tax exclusion different from the federal exclusion?

Yes, significantly. The 2025 federal estate tax exclusion is $13.99M per person — nearly twice the NY exclusion of $7.16M. This means many estates that owe no federal estate tax still owe NY estate tax. The federal exclusion is also portable between spouses; NY's is not. For NY residents with estates between $7.16M and $13.99M, NY estate tax planning is particularly important.

New York Estate Tax Calculator 2025 — Cliff, Exclusion & Rates

Calculate your New York State estate tax. The 2025 NY exclusion is $7,160,000 — but estates above 105% of the exclusion ($7.52M) trigger the full NY cliff, eliminating the entire exclusion credit. Rates up to 16%.

New York State imposes its own estate tax — separate from and in addition to the federal estate tax. For 2025, the NY basic exclusion amount is $7,160,000. But New York has a notorious "cliff": if your taxable estate exceeds 105% of the exclusion threshold, the entire exclusion credit is eliminated and the full estate is taxed at rates up to 16%. This cliff creates a dramatic discontinuity — an estate of $7.52 million pays the same NY estate tax as an estate of $100 million. Estates in the $7.16M–$7.52M danger zone need careful planning.

How NY Estate Tax Is Calculated

New York computes estate tax in four steps:

Step 1 — Compute taxable estate:

Taxable estate = Gross estate
              − Debts and administration expenses
              − Marital deduction (unlimited for US-citizen spouse)
              − Charitable deduction

Step 2 — Compute gross NY estate tax using the rate schedule:

NY gross tax = Sum of marginal rates applied to taxable estate
               (3.06% on first $500K, graduating to 16% above $10.1M)

Step 3 — Apply the exclusion credit (with cliff phaseout):

Credit = Tax on $7,160,000 exclusion × (1 − phaseout fraction)

Where phaseout fraction:
  = 0 if estate ≤ $7,160,000           → no tax
  = linearly 0→1 if $7.16M–$7.52M     → partial credit
  = 1 if estate ≥ $7,518,000           → CLIFF: zero credit

Step 4 — NY estate tax = gross tax − credit:

NY estate tax = max(0, gross tax − credit)

The cliff in practice:

Estate at $7.16M: $0 NY tax (full exclusion)
Estate at $7.3M: some NY tax (partial phaseout)
Estate at $7.52M: ~$1,042,000 NY tax — suddenly jumps because the full credit ($1,042,000) is lost
No-man's land: being in the $7.16M–$7.52M range is the worst position

When to Use This Calculator

Use this calculator when:

Planning gifts to avoid the cliff — If the taxable estate is between $7.16M and $7.52M, gifting assets down below $7.16M eliminates the entire NY estate tax, not just the marginal tax on the gifted amount.
Evaluating the marital deduction — Explore how much to pass to a spouse vs. into a credit shelter trust to avoid cliff exposure in the survivor's estate.
Comparing NY vs. federal estate tax exposure — The NY exclusion ($7.16M) is far below the federal exclusion ($13.99M in 2025), so many NY residents need NY-specific planning even when federal tax is zero.
Business succession planning — For business owners with NY estate tax exposure, modeling the estate tax cost of different succession structures (sale, gift, GRAT, family LLC) helps quantify the planning benefit.
Quantifying the value of AB trust planning — For married couples, an AB trust or credit shelter trust ensures both spouses' $7.16M exclusions are used, potentially saving up to $1.04M in NY estate tax.

Understanding the Inputs

Gross Estate Value: Total fair market value of all assets at the date of death: real property, investment and bank accounts, retirement accounts (IRAs if payable to estate or non-spouse), life insurance proceeds payable to the estate, business interests, and personal property. Retirement accounts with designated beneficiaries pass outside the estate — they are included here only if the estate itself is the beneficiary.
Debts, Mortgages & Admin Expenses: Mortgages, personal debts owed at death, funeral expenses, and estate administration costs (attorney fees, executor fees, court costs). All reduce the taxable estate dollar for dollar.
Marital Deduction: Assets passing outright to a US-citizen surviving spouse qualify for an unlimited marital deduction — zero NY estate tax on those amounts in the first estate. Important: New York does NOT allow portability of unused exclusion between spouses. Each spouse must use their own exclusion, making credit shelter trusts and other estate planning tools more important in NY than in states with portability.
Charitable Deduction: Bequests to qualifying charitable organizations reduce the taxable estate dollar for dollar. Charitable remainder trusts, charitable lead trusts, and direct bequests to 501(c)(3) organizations all qualify.
