The New York estate tax cliff
New York's estate tax exemption is uniquely structured. If your taxable estate is at or below the exemption (~$7.16M in 2026), you pay no New York estate tax. If it exceeds 105% of the exemption, the exemption disappears entirely and the entire estate is taxed from the first dollar at NY's progressive rates up to 16%.
An $8M estate can owe roughly $670,000 in NY estate tax that a $7.5M estate owes nothing on. The cliff is the single most important planning constraint for affluent NY families and is solved primarily through lifetime gifting, ILITs holding life insurance outside the estate, and charitable bequests calibrated to land below the cliff.
