Many Long Island families are told they have no estate tax problem because their estate is well under the federal exclusion. That answer skips the tax that is far more likely to apply to them: New York’s.
What you need to know
- New York and the federal government each impose a separate estate tax, with different exclusion amounts, different rules, and separate returns.
- New York’s exclusion is substantially lower than the federal exclusion, so an estate can owe New York tax while owing nothing federally.
- New York has a “cliff”: once a taxable estate exceeds the exclusion by more than a set percentage, the benefit of the exclusion is lost entirely and the whole estate is taxed, not just the excess.
- The federal system allows portability of an unused exclusion between spouses. New York does not, which makes trust planning at the first death more important here.
- New York has no separate gift tax, but certain gifts made within a defined period before death are added back into the New York taxable estate.
- Every dollar figure, percentage and time window in this area is adjusted or amended from time to time and must be confirmed for the applicable year.
Two taxes, two sets of rules
An estate tax is a tax on the transfer of assets at death, measured by the value of what the decedent owned or controlled. The federal estate tax applies nationwide. New York imposes its own tax on the estates of New York residents, and on New York real property and tangible personal property owned by nonresidents.
Both start from a similar concept of the gross estate — real property, accounts, retirement plans, business interests, and life insurance the decedent owned — but they diverge quickly on exclusions, deductions and credits.
The practical consequence for Long Island households is straightforward. Home values in Suffolk County, a retirement account built over a career, and a life insurance policy can add up to a New York taxable estate faster than people expect.
Confirm the numbers. The New York basic exclusion amount is adjusted periodically, the federal exclusion is indexed and has been subject to scheduled changes, and rate schedules can be amended. No figure in this area should be relied on without checking it for the year in question.
The New York cliff
This is the mechanism that makes New York estate tax planning different from federal planning, and it is the point most worth understanding.
Under the federal system, the exclusion works like a deduction. If an estate exceeds the exclusion, only the excess is taxed. Going over by a small amount produces a small tax.
New York does not work that way. New York applies a credit that is phased out as the taxable estate rises above the basic exclusion amount. Once the estate exceeds the exclusion by more than a set percentage, the credit is gone completely — and the tax is computed on the entire taxable estate from the first dollar, not merely on the amount above the exclusion.
The result is a narrow band, just above the exclusion, in which each additional dollar of estate value can produce far more than a dollar of additional tax. Two estates that differ modestly in size can produce very different tax bills. The exclusion amount and the phase-out percentage are set by statute and have changed over time; both must be confirmed for the year of death.
What families do about the cliff
Because the penalty for landing just over the line is so steep, planning tends to focus on keeping the taxable estate below it, or on making the excess disappear.
- Lifetime giving. New York has no separate gift tax, so lifetime gifts can reduce the New York taxable estate — subject to the add-back rule discussed below, and to federal gift tax reporting.
- Charitable gifts at death. A charitable bequest is deductible and reduces the taxable estate. Some documents include a formula gift designed to bring an estate back under the threshold, which should be drafted with care and only where there is genuine charitable intent.
- Removing life insurance from the estate. A policy the decedent owned is generally included at its death benefit. Holding a policy in an irrevocable life insurance trust may keep the proceeds out of the taxable estate if it is structured and administered properly.
- Credit shelter planning between spouses. Discussed in the next section, and unusually important in New York.
- Disclaimers after death. A qualified disclaimer by a beneficiary, made within the required period and before accepting benefits, can redirect assets and in some cases improve the tax result. This is a post-death option with strict requirements and short deadlines.
Portability, and why New York’s lack of it matters
Federal law allows a surviving spouse to use the deceased spouse’s unused exclusion amount. That is portability. It is not automatic: it requires a timely filed federal estate tax return electing it, even when the estate is far too small to require a return. Families routinely miss it.
New York has no equivalent. If the first spouse to die leaves everything outright to the survivor, that spouse’s New York exclusion is simply lost. The survivor dies later with a larger estate and only one exclusion to apply against it.
That is why credit shelter trust planning — sometimes called a bypass trust — remains relevant for New York couples whose combined assets approach the state threshold, even though national articles often describe such trusts as obsolete. The trust holds an amount up to the New York exclusion at the first death for the survivor’s benefit and keeps it out of the survivor’s taxable estate.
Building that flexibility in typically requires a trust rather than a simple will. The comparison of the two is covered in the firm’s guide to wills and revocable living trusts, and the estate planning page describes how the structures are used together.
| Feature | Federal estate tax | New York estate tax |
|---|---|---|
| Exclusion amount | Higher; indexed and subject to scheduled change — confirm for the year | Lower; adjusted periodically — confirm for the year |
| Treatment above the exclusion | Only the excess is taxed | Credit phases out; past the threshold the whole estate is taxed |
| Portability between spouses | Available by election on a timely filed return | Not available |
| Separate gift tax | Yes, unified with the estate tax | No separate gift tax, but an add-back applies to certain gifts |
| Marital deduction | Yes, for qualifying transfers to a U.S. citizen spouse | Yes, generally following the federal pattern |
| Nonresident exposure | Different rules for non-U.S. persons | New York real and tangible property is taxed to nonresidents |
| Return deadline | Generally nine months after death, extension available to file | Generally nine months after death, extension available to file |
The New York gift add-back
New York repealed its gift tax years ago, so a lifetime gift is not itself taxed by the state. But to prevent deathbed transfers from defeating the estate tax, New York adds certain taxable gifts back into the taxable estate when they were made within a defined period before death.
The concept matters more than the arithmetic: a gift made shortly before death may not accomplish what a gift made years earlier would. The length of the look-back window, the categories of gifts caught by it, and any exceptions — including for gifts made while the donor was not a New York resident, or of property outside New York — have been the subject of amendment and sunset provisions. The rule in effect at the date of death governs, and it should be confirmed before relying on a late gift as a tax strategy.
Gifting also has consequences beyond tax. A gift of appreciated property removes the step-up in income tax basis the beneficiary would have received at death, which can cost more in capital gains tax than the gift saves. A gift can also create a period of ineligibility for long-term care Medicaid, which the firm’s elder law page addresses.
Basis versus estate tax. For many families the more valuable planning question is income tax basis, not estate tax. Property that passes at death generally receives a new basis equal to its date-of-death value. Giving that property away during life usually gives up that benefit.
Filing, deadlines and what the executor has to do
A New York estate tax return is generally required when the gross estate plus certain adjustments exceeds the basic exclusion amount for the year of death, and it is due within nine months, with an extension of time to file available. An extension to file is not an extension to pay; interest generally accrues on tax paid late.
A federal return may be required, or worth filing voluntarily to elect portability. Executors often need appraisals of real property and closely held business interests to support reported values. The firm’s probate and estate administration page describes the fiduciary’s obligations, and valuation and succession issues are addressed through business planning and succession.
New York residents who own a home in another state should also note that the New York calculation reaches the worldwide estate, with relief for real and tangible property located outside the state.

Frequently asked questions
My estate is under the federal exclusion. Do I still need to worry?
Possibly. New York’s exclusion is much lower than the federal one, so an estate that owes nothing federally can still owe New York tax. On Long Island, a house, retirement accounts and life insurance together often bring an estate closer to the New York threshold than people expect.
What exactly is the New York cliff?
New York gives a credit that offsets tax up to the exclusion amount, but that credit phases out as the estate rises above it. Once the estate exceeds the exclusion by more than a set percentage, the credit disappears and the tax is calculated on the entire taxable estate rather than only the amount above the exclusion. The exclusion amount and the percentage should be confirmed for the year of death.
Can my spouse use my unused New York exclusion after I die?
No. New York does not offer portability. If everything passes outright to a surviving spouse, the first spouse’s New York exclusion is generally lost. That is the main reason credit shelter or disclaimer trust planning is still used by New York couples.
Should I give assets away now to reduce the tax?
It depends on the facts. New York has no gift tax, but certain gifts made within a window before death are added back, gifts of appreciated property forfeit the basis step-up, and gifts can affect long-term care eligibility. Gifting can be effective, but it should be evaluated against those consequences rather than assumed to help.
Do I have to file a federal return if no tax is due?
Often not, but filing may still be worthwhile for a married couple in order to elect portability of the unused federal exclusion. That election generally requires a timely filed return, and missing it can matter years later at the survivor’s death.
