New York Estate Tax & the ‘Cliff’ for Long Island Homeowners

New York imposes its own estate tax, separate from the federal estate tax, on estates above the New York exemption — and because of the “cliff,” an estate that exceeds the exemption by more than 5% loses the exemption entirely and is taxed on the whole estate. For Long Island families, decades of home appreciation in Nassau and Suffolk can push an estate over that line, so the cliff is the single most important number in local estate-tax planning. Exemption figures change annually — always verify the current-year amount.

How the New York estate tax works

New York taxes the taxable estate of residents (and New York real property of non-residents) under New York Tax Law Article 26. If your estate is below the exemption, no New York estate tax is due. Above it, a graduated rate applies. There is no New York tax on what passes to a surviving spouse (the marital deduction) or to charity.

Definition — gross estate: the total value of everything you own at death, including real property, accounts, retirement plans, and life insurance you control. Definition — taxable estate: the gross estate minus deductions (debts, marital, charitable). Definition — exemption: the amount that can pass free of estate tax.

The New York “cliff” (105% rule)

The cliff is what makes New York different from the federal system. New York does not simply tax the amount over the exemption — once your taxable estate exceeds 105% of the exemption, the exemption phases out completely and the entire estate is taxed from the first dollar.

Worked example (illustrative — verify current figures): Suppose the New York exemption is $X. An estate just under $X owes nothing. An estate at exactly $X owes nothing. But an estate at roughly 105% of $X loses the exemption entirely, so a relatively small amount of extra value can trigger tax on the whole estate — sometimes a tax larger than the overage itself. For a Long Island couple whose Garden City or Huntington home quietly appreciated past the threshold, this is a costly surprise.

Federal vs. New York estate tax

Feature	Federal	New York
Separate exemption	Yes (high, indexed)	Yes (lower)
“Cliff” loss of exemption	No	Yes (105% rule)
Portability between spouses	Yes	No
Inheritance tax	No	No
Gift tax	Yes	No (but 3-year add-back)

No New York inheritance or gift tax — but watch the add-back

New York has no inheritance tax (a tax on what heirs receive) and no gift tax. However, New York adds back into the taxable estate any taxable gifts made within three years of death. So a deathbed transfer to dodge the cliff can be pulled back into the estate. Gifts made more than three years before death are not added back.

Portability and why New York lacks it

Portability lets a surviving spouse use a deceased spouse’s unused federal exemption. New York has no portability. The planning implication is significant: a Long Island couple cannot rely on the survivor “inheriting” the first spouse’s New York exemption. Instead, a credit shelter (bypass) trust is often used so the first spouse’s exemption is not wasted.

Strategies to reduce exposure

• Credit shelter / bypass trusts — capture the first spouse’s New York exemption.
• Lifetime gifting — outside the 3-year window, to shrink the taxable estate.
• Irrevocable life insurance trusts (ILITs) — keep life insurance proceeds out of the taxable estate.
• Charitable giving — deductible and exemption-reducing.
• Trust planning — coordinate with revocable and irrevocable trusts.

Long Island cliff exposure in practice

Long Island’s high homeownership rate is exactly what creates cliff risk. Unlike a Manhattan co-op shareholder, a Long Island homeowner holds appreciated real property — a single-family home in Massapequa, a waterfront property in the Hamptons, or a multi-acre Suffolk parcel — plus a boat, a business, or a second home. Add retirement accounts and life insurance, and a “house-rich” estate can exceed the New York exemption without the family ever feeling wealthy. This is why local cliff planning often matters more here than anywhere else in the state.

Frequently asked questions

Does Long Island have its own estate tax? No separate local tax — Nassau and Suffolk estates are subject to the statewide New York estate tax and the federal estate tax, not a county tax.

What is the New York estate tax cliff? Once a taxable estate exceeds 105% of the New York exemption, the exemption disappears and the entire estate is taxed, not just the excess.

Does New York have an inheritance tax? No. New York has neither an inheritance tax nor a gift tax, though gifts within three years of death are added back to the taxable estate.

Can my spouse use my unused New York exemption? No — New York has no portability. A credit shelter trust is the common workaround.
