The New York Estate Tax Cliff: What Families Need to Know

New York has one of the most unusual, and punishing, estate tax structures in the country. While most states that impose an estate tax simply tax the amount above the exemption, New York operates what tax planners call a “cliff.” If your estate exceeds the exemption threshold by even a small margin, the tax applies not just to the excess, but to your entire estate, which is a crucial consideration for understanding the New York Estate Tax.

For families in Westchester County and the greater New York metropolitan area, where real estate values alone can push an estate over the threshold, this is not an abstract concern. It is a planning problem that deserves serious attention.

The implications of the New York Estate Tax are significant, especially for larger estates that may inadvertently cross the threshold.

New York’s Estate Tax Exemption

New York State imposes its own estate tax, separate from and in addition to the federal estate tax. The New York exemption is indexed for inflation each year. For 2024, the exemption is $6.94 million per individual. Estates valued below this threshold owe no New York estate tax.

By comparison, the federal estate tax exemption is $15 million per individual as of 2026, more than double the New York figure. This means many estates that owe nothing to the federal government still face a meaningful New York estate tax liability.

It is also worth noting that New York does not recognize portability, the ability for a surviving spouse to use the deceased spouse’s unused exemption. Under federal law, as of 2026, a surviving spouse can effectively combine both exemptions under the One Big Beautiful Bill Act, shielding up to $30 million from federal estate tax. New York offers no such benefit. Each spouse’s New York exemption must be used independently, making proactive planning especially important for married couples.

What Is the Estate Tax Cliff?

The cliff is the feature that makes New York’s estate tax uniquely dangerous for estates in a certain range. Under New York Tax Law § 952, the exemption begins to phase out once an estate’s value exceeds 100% of the exemption amount. Once the estate reaches 105% of the exemption, the exemption is completely eliminated, and the entire estate is subject to tax from the first dollar.

To illustrate the cliff concretely: if the New York exemption is $6.94 million and your taxable estate is $7.28 million (105% of the exemption), you receive no exemption at all. Your entire $7.28 million estate is subject to New York estate tax at rates ranging from 3.06% to 16%. An estate of $7.28 million could owe over $1 million in New York estate tax, while an estate of $6.93 million owes nothing.

That gap, a $350,000 difference in estate value producing over $1 million in additional tax, is the cliff.

Why Westchester Families Are Particularly Exposed

In much of the country, a $6.94 million estate represents generational wealth. In Westchester County, it can represent a family home, retirement savings, and a life insurance policy. The median home value in communities like Scarsdale, Bronxville, and Rye routinely exceeds $1.5 million. Add a 401(k), brokerage accounts, and a life insurance policy, and many families in this region find themselves in cliff territory without ever thinking of themselves as wealthy.

Life insurance is a particularly common surprise. Many people do not realize that life insurance proceeds are included in the taxable estate if the decedent owned the policy at the time of death. A $1 million term life policy held in your own name can push an otherwise below-threshold estate directly into cliff territory.

Strategies for Managing the Cliff

There is no single solution that works for every family, but several planning tools are commonly used to address New York estate tax exposure:

• Annual gifting. The federal annual gift tax exclusion allows you to give up to $18,000 per recipient per year (2024 figure) without gift tax consequences and without reducing your lifetime exemption. Systematic gifting over time can meaningfully reduce the size of a taxable estate. New York does not have a separate gift tax, which makes lifetime gifting a particularly effective tool for New York residents.
• Irrevocable Life Insurance Trust (ILIT). By transferring ownership of a life insurance policy to an irrevocable trust, the death benefit is excluded from your taxable estate. An ILIT is one of the most commonly used tools for keeping life insurance proceeds out of the estate tax calculation.
• Spousal Lifetime Access Trust (SLAT). A SLAT allows one spouse to make a gift to an irrevocable trust for the benefit of the other spouse, removing the assets from the taxable estate while still allowing the beneficiary spouse indirect access to the funds. This strategy has its own complexity and risks, including what planners call the “breciprocal trust doctrine,” and requires careful drafting.
• Credit shelter trusts. Because New York does not recognize portability, married couples often use a credit shelter trust (also called a bypass trust or B trust) at the death of the first spouse to preserve and use each spouse’s New York exemption separately.
• Charitable giving. Charitable bequests and charitable remainder trusts reduce the taxable estate while accomplishing philanthropic goals. Assets passing to qualified charities are fully deductible for estate tax purposes under both federal and New York law.

The Federal Exemption After the One Big Beautiful Bill Act

The federal estate tax landscape changed significantly with the enactment of the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025. The OBBBA permanently increased the federal estate, gift, and generation-skipping transfer tax exemption to $15 million per individual, $30 million for married couples, effective January 1, 2026, with annual inflation adjustments beginning in 2027. Unlike the temporary increase under the Tax Cuts and Jobs Act of 2017, the OBBBA exemption carries no sunset provision.

The practical effect for most New York families is that federal estate tax is now a concern only for the wealthiest estates. With a $15 million federal exemption against a New York exemption of approximately $7 million, the state-level tax has become the primary estate tax exposure for the majority of New York residents who engage in estate planning. The gap between the two exemptions, and the cliff that makes New York’s tax particularly punishing, has never been more relevant.

This shift also changes the planning focus. With federal transfer taxes effectively off the table for most families, New York estate tax mitigation and income tax planning, including preserving a stepped-up basis at death, become the central priorities in a well-designed estate plan.

Estate Tax Planning Is Not Just for the Ultra-Wealthy

The most important takeaway for New York families is this: estate tax planning is not reserved for the very wealthy. In a high-cost region like Westchester, a family with a paid-off home, retirement savings, and a life insurance policy can find itself facing a six-figure tax bill that a modest amount of planning could have substantially reduced or eliminated entirely.

The earlier the planning begins, the more options are available. Many of the most effective strategies, gifting programs, irrevocable trusts, insurance restructuring, require time to implement properly and cannot be put in place at the last minute.
