NY Estate Tax Cliff 2026: What Homeowners Should Plan For

Can fifty thousand dollars of extra value cost an estate more than a hundred thousand dollars in tax? In New York, the answer is yes, and the mechanism responsible has a name among estate planners: the cliff.

The federal estate tax has receded from most families’ concerns. For 2026, the IRS sets the federal basic exclusion at $15,000,000 per person (IRS). New York runs its own estate tax on a much lower threshold, with a design feature that punishes estates landing just above it. For owners on Long Island, where a house can represent a large share of what a person leaves behind, the home’s value is often the variable that decides which side of that line an estate falls on.

The 2026 Numbers

The New York State Department of Taxation and Finance sets the basic exclusion amount at $7,350,000 for dates of death from January 1 through December 31, 2026, up from $7,160,000 for 2025 (NY DTF). An estate at or below that figure owes no New York estate tax.

Above it, the tax is calculated on a graduated schedule in New York Tax Law § 952, with rates beginning at 3.06% and reaching 16% on the portion of a taxable estate above $10,100,000 (NY Tax Law § 952).

How the Cliff Actually Works

Most tax exemptions work like a floor: the first dollars are exempt, and tax applies only to the excess. New York’s does not.

Under § 952(c), when an estate exceeds the basic exclusion amount by up to 5%, the credit that normally wipes out the tax shrinks rapidly as the estate grows. Once the estate exceeds 105% of the exclusion, the statute says plainly that “no credit shall be allowed” (NY Tax Law § 952). The tax is then computed on the entire estate, from the first dollar.

For 2026, 105% of $7,350,000 is $7,717,500. That narrow band between the two figures is the cliff.

What the Cliff Looks Like in Dollars

The figures below apply the § 952 rate schedule and credit formula to hypothetical taxable estates for a 2026 date of death. They are illustrative calculations, not tax advice, and an actual return involves deductions and adjustments that change the taxable figure.

New York taxable estate	Approximate NY estate tax
$7,300,000	$0
$7,350,000	$0
$7,400,000	about $136,800
$7,500,000	about $386,400
$7,700,000	about $721,700
$7,800,000	about $746,000
$8,000,000	about $773,200

An estate $50,000 over the threshold owes roughly $136,800, more than the amount by which it exceeded the line. Between $7.35 million and roughly $7.7 million, the effective marginal rate on the excess runs well above 100%.

The Suffolk County law firm Twomey Latham reached the same figures in its February 2026 analysis, describing a $7.4 million estate that “will owe more than $136,000 in New York estate tax, representing an effective tax rate of over 250%,” and a $7.8 million estate that owes over $745,000 (Twomey Latham).

Why the House Is Usually the Swing Asset

Federal and New York estate taxes both start with the gross estate, which the IRS describes as everything a person owns or has certain interests in at death, valued at fair market value rather than purchase price. Real estate, cash and securities, insurance, trusts, annuities, and business interests can all be included (IRS).

That fair-market-value rule is where Long Island homeowners should pay attention. A house bought decades ago for a fraction of its current worth enters the estate at what it would sell for today. Add retirement accounts, a brokerage portfolio, and life insurance the owner controls, and an estate that seems comfortably modest on paper can drift toward the threshold without anyone having made a deliberate decision.

Because real estate values move, the house also introduces uncertainty. An estate sitting just under $7.35 million today could cross the line through appreciation alone. Owners whose estates fall anywhere near the range should expect the calculation to change from year to year, both as the exclusion amount adjusts for inflation and as property values shift.

Maison Pawli has written about the historical side of this problem in the Gold Coast estate as tax problem, which traces how heirs of large North Shore properties have sold, subdivided, and converted them since 1945. The modern version is less dramatic and far more common: an ordinary family home that happens to be worth a great deal.

Married Couples: The Portability Gap

At the federal level, a surviving spouse can elect to use a deceased spouse’s unused exemption, a feature known as portability, by filing a timely federal estate tax return (IRS).

New York does not offer that feature. As the Long Island firm Israeloff Law notes, “New York does not allow spousal portability, meaning a surviving spouse cannot ‘inherit’ a deceased spouse’s unused exemption” (Israeloff Law).

The practical consequence is significant for couples who leave everything to each other. The first spouse’s transfer to the survivor typically qualifies for the marital deduction, so no tax is due then, but that spouse’s New York exclusion goes unused. When the survivor dies, the combined assets, including the house, face a single $7.35 million exclusion (adjusted for the year of death). A couple whose joint estate sits around $10 million could owe nothing federally and still face a substantial New York bill.

Planning Approaches Owners Discuss With Counsel

The strategies below are commonly discussed by New York estate practitioners. Whether any of them fits a particular family depends on facts only an attorney can evaluate.

Lifetime Gifts, and the Three-Year Rule

New York does not currently impose a separate gift tax, which means lifetime gifts can reduce the size of a taxable estate (Twomey Latham). There is a significant condition. The Department of Taxation and Finance requires an estate to add back taxable gifts made during the three-year period ending on the date of death that were not already included in the federal gross estate (NY DTF). As Twomey Latham puts it, “The catch is that you must survive at least three years from the date you make the gift.”

Gifting the house itself raises a separate issue. Property inherited at death generally receives a basis equal to its fair market value on the date of death under the federal step-up rule (26 U.S.C. § 1014). Property received as a lifetime gift is governed by a different section, which generally carries the donor’s basis over to the recipient (26 U.S.C. § 1015). A long-held Long Island house given away during life can hand the recipient a large built-in capital gain that would have been erased had the house passed at death. For more on how gains are calculated on a sale, see the earlier post on capital gains and the Long Island home sale.

Disclaimer and Credit Shelter Trusts

For married couples, estate plans can be drafted so the first spouse’s exclusion is used rather than wasted. Twomey Latham describes the disclaimer trust, in which the surviving spouse can refuse part or all of an inheritance so that the disclaimed assets pass into a bypass or credit shelter trust, which is not counted in the survivor’s estate for estate tax purposes (Twomey Latham).

Formula Charitable Bequests

Some plans include a clause that directs to charity only the amount needed to bring the taxable estate back down to the exclusion, applying only when the gift would cost less than the tax it prevents. Twomey Latham’s example is a $7.4 million estate that gives $50,000 to charity and, by doing so, avoids more than $136,000 in New York tax.

Revisiting Old Documents

Many wills and trusts in circulation were drafted when the federal exemption was lower, when New York’s exclusion was different, or before the house was worth what it is today. The New York cliff is sensitive enough that a plan written a decade ago may produce a very different result now.

Filing and Timing

An estate that must file a New York return generally has nine months from the date of death to file Form ET-706 and pay the tax, and it must include a federal Form 706 with the New York filing even when no federal return is otherwise required (NY DTF). Extensions are available in limited circumstances.

Real property can also be affected procedurally. The Department’s guidance notes that transferring real property may require a release of lien, which bears on how quickly an executor can sell or transfer a house after death. Families expecting to sell an inherited home should factor that into their timeline, alongside the practical steps covered in the seller’s timeline from decision to closing on the North Shore.

A Reasonable First Step for Owners

For most owners, nothing here requires immediate action. What it does suggest is a periodic, rough accounting: current market value of the house and any other real estate, retirement and investment accounts, life insurance the owner controls, and business interests. If that total lands within a few hundred thousand dollars of the New York exclusion, or above it, a conversation with an estate attorney is worth scheduling while there is still time to plan around the three-year rule.

A market valuation of the home, rather than an assessed value or a years-old appraisal, is a useful input for that conversation. Assessed values and market values often differ, as discussed in how Long Island’s tax grievance process relates to market value.
