The New York Estate Tax Cliff: The Trap That Pushes Wealthy Families Out

Many Long Island families assume that estate tax is not something they should worry about because their estates fall well below the federal exemption. It’s a fair assumption. With the federal exemption at $15 million per person in 2026, it’s easy to see why Long Islanders may believe they are in the clear. 

Unfortunately, the state of New York operates very differently than the federal government. The NY estate tax exemption in 2026 is set at $7,350,000, less than half the federal exemption. As a result, a high-value Long Island home, retirement accounts, investments, business interests, and life insurance can place a family much closer to that number than expected.

Beyond the lower exemption rate, New York also treats estates near the threshold differently from most states. For families approaching the New York estate tax cliff, falling safely below the federal exemption does not mean the estate is protected from state tax. Understanding both sets of rules early creates more time to evaluate the options, coordinate with the right advisors, and preserve more of the wealth intended for the next generation.

What the Cliff Is, and Why New York Stands Alone

Most estate tax systems, including the federal system, tax only the amount above the exemption. Cross the line by $50,000, and the estate owes tax on that $50,000; nothing more.

New York does not work that way. Once a taxable estate exceeds 105% of the exemption, the entire credit is lost, and the whole estate becomes taxable, not just the portion above the threshold. Families who land just past the cliff can end up worse off than families with slightly smaller estates who stayed under it.

No other state structures its estate tax this way. That single design choice is one of the more overlooked reasons wealthy families reconsider New York as their permanent home.

The 2026 Numbers Behind the Cliff

For Long Island residents, the numbers matter. Here are a few important considerations when creating your estate strategy:

• New York estate tax exemption 2026: $7,350,000 per person
• Cliff threshold (105% of the exemption): $7,717,500
• New York estate tax rate: graduated brackets from 3.06% up to 16%, applied to the full estate once the cliff is triggered

If the estate exceeds $7,350,000 but remains below $7,717,500, New York generally applies tax only to the amount above the exclusion. Once the estate rises above $7,717,500, the New York exemption is lost, and the full estate becomes subject to state estate tax

What Falling Off the Cliff Actually Costs

Consider a hypothetical example to see how this could play out for actual New Yorkers. Picture an estate valued at roughly $7.8 million, just above the $7,717,500 cliff threshold. Depending on the exact composition of the estate, New York’s 2026 rate table could produce a tax bill of approximately $746,000.

Here’s what makes that number so jarring. The amount that pushed this estate over the exemption is only about $450,000. However, the tax bill it would trigger could amount to nearly $746,000, far more than the overage itself. Of course, this is just an illustrative example. Actual liability depends on the full composition and valuation of what you own, and calls for a review with a qualified advisor.

Why $7.35 Million Is Closer Than It Sounds on Long Island

For many families, $7.35 million seems like a number reserved for the ultra-wealthy. On Long Island, it rarely is.

A home that’s appreciated over the years, decades of retirement contributions, a brokerage account, a business interest, and a life insurance policy bought years ago (depending on how it’s owned, the death benefit could count toward your taxable estate, even if you never touched the cash value) can add up faster than expected. 

Exposure to estate tax in Nassau/Suffolk can catch people off guard for a pretty simple reason: home equity, retirement savings, and insurance proceeds tend to be discussed separately in day-to-day life. They don’t always get added up as one number until somebody makes the time to do it.

Strategies That May Help Reduce Exposure

There is some good news for Long Islanders looking to preserve their wealth for future generations. Families who plan ahead sometimes have options that can help avoid New York estate tax, or at least keep exposure closer to a more manageable range.

Lifetime gifting is often a tool worth exploring. New York doesn’t impose a gift tax of its own, and moving assets out of an estate gradually, within the applicable rules, may reduce the amount that eventually counts against the exemption. One detail worth knowing: Current New York legislation states that gifts made within three years of death can be added back into the taxable estate, so timing tends to matter.

Credit-shelter and bypass trusts address something many families overlook: New York doesn’t allow spousal portability. On the federal side, a surviving spouse can generally inherit whatever exemption the first spouse didn’t use. New York doesn’t offer an equivalent, so without planning, one spouse’s exemption can simply disappear.

A bypass trust can help preserve it. Assets from the first spouse’s estate move into the trust rather than passing directly to the surviving spouse, who can often still benefit from those assets during their lifetime. Structured well in advance, this can help a couple use both exemptions rather than losing one by default.

Charitable gifting can, in some cases, help keep an estate under the cliff. Directing a portion of an estate toward a cause that matters to the family, rather than letting it exceed the 105% threshold, could, in certain situations, leave more for the family in the end than passing the full amount outright, while also supporting something meaningful along the way.

Strategies like these tend to work better with time and coordination behind them, rather than as a last-minute decision. This is generally where the right team matters. An experienced advisor familiar with New York’s estate tax rules, working alongside an estate attorney and CPA, can often help identify which options may make sense for a given family’s situation and ensure nothing gets left to chance simply because the numbers weren’t being tracked.

The Numbers Are Set to Move

The exemption adjusts for inflation annually, so the exact figures shift from year to year. Beyond the routine adjustment, there is active legislative discussion in Albany about the exemption itself, including proposals that would reduce it rather than continue increasing it.

A plan built around this year’s threshold could look meaningfully different if that threshold moves. Families with estates near the cliff, on either side of it, benefit from a plan designed to hold up against a changing number rather than one calculated once and filed away.

A Quick Self-Check to See Where You Stand

Before assuming an estate plan is settled, there are a few questions worth asking honestly:

• Have all assets (home, retirement accounts, brokerage accounts, life insurance death benefit, business interests) been added together as one combined estate value, rather than reviewed separately?
• Is the current estate value within $500,000 of the $7,350,000 exemption in either direction?
• Does the plan account for New York’s lack of spousal portability?
• Has a gifting or trust strategy been discussed with an attorney or CPA in the last two years?
• Would the plan still hold up if the exemption were lowered by future legislation?

Answering “no” to any of these is a reasonable sign it’s time for a closer look.
