New York
Reviewed June 2026Federal §453 conformity
Yes. New York starts from your federal return, so gain reported on the installment method federally is reported the same way for New York. The complications are not about whether the deferral works — they are about who New York gets to keep taxing, which is where this state earns its reputation.
Nonresident sourcing
Gain from New York real estate or a New York business is New York income even for sellers who live elsewhere, and each installment payment keeps that label. New York also closed the door on a once-popular escape: when an S corporation stock sale is treated as an asset sale for tax purposes, or the company sells assets and distributes the installment note, nonresident shareholders are taxed by New York on their share of the gain.
Withholding
Nonresidents selling New York real property must prepay estimated tax at closing on Form IT-2663, computed on the gain. For an installment sale, the prepayment rules need to be coordinated with the payment schedule before the closing table, not at it.
Selling, then moving (residency change)
New York has a tool most states lack: when a resident moves away, the state can require deferred income — including installment gain from a sale made while a resident — to be reported on the way out, unless the gain stays taxable to New York anyway or the taxpayer posts security and keeps reporting year by year. Add famously aggressive residency audits, and the move-then-collect-tax-free plan needs more engineering here than anywhere else except California.
Pass-through entity (PTE) tax election
New York's PTE tax election is among the most valuable in the country at these rates, and it carries the least forgiving calendar: the election for a given year is generally due March 15 of that year. For an installment sale, that means a live decision early every single year payments arrive — miss one March and that year's SALT-cap workaround is gone. New York City has its own parallel election for city tax. As with California, the entity has to stay alive to keep electing.
Estate and IRD
New York has an estate tax with an unusual cliff: estates modestly over the exemption can lose the entire exemption, not just the excess. An installment note held at death counts toward that number at its value, while the heirs separately pay income tax as payments arrive. For sellers carrying a large note late in life, the cliff math deserves a seat at the planning table.
Planning notes
Three New York-specific items to settle early: whether any planned move triggers the departure accrual rules (and whether posting security beats accelerating), the March 15 PTE election calendar for every payment year, and — for deals structured as S corporation stock sales — the understanding that New York will look through to the assets. New York City residents should also price in the city's own income tax on each payment.
Under New York's special accrual rules, deferred installment gain from a sale made while a resident may have to be reported when you move out — unless it remains New York-source or you post acceptable security and keep reporting annually. Decide bond-versus-accelerate before the moving truck is booked.
New York's PTE tax election is generally due March 15 of the year it covers. An installment sale means making that election on time every year payments arrive, for the state and — for city residents — New York City separately.
