The federal exclusion, New York State tax rules, inherited property step-up in basis, and the situations where a Long Island home sale creates a genuine tax event — explained in plain language.
Talk to Our BrokerThe capital gains tax implications of a Long Island home sale are frequently misunderstood — and the misunderstandings run in both directions. Some sellers expect a large tax bill that does not materialize due to the primary residence exclusion. Others are surprised by tax exposure on inherited properties where the basis calculation works differently than expected.
This guide provides general information to help Long Island sellers understand the key concepts. It is not tax advice. Before making any decisions based on tax implications, consult a qualified tax professional or CPA familiar with New York State real property transactions.
Federal tax law provides a significant exclusion for gains on the sale of a primary residence. Single filers can exclude up to $250,000 of capital gain. Married couples filing jointly can exclude up to $500,000. Given Long Island's substantial home price appreciation over the past decade, this exclusion is relevant to a large number of Long Island sellers.
You must have owned and used the home as your primary residence for at least two of the five years immediately before the sale. The two years do not need to be consecutive. You cannot have used this exclusion in the two years before the current sale.
Capital gain = sale price minus your adjusted basis. Your basis is what you paid for the home, plus the cost of capital improvements made during ownership. Keep records of significant improvements — they directly reduce your taxable gain.
If your gain exceeds $250,000 (single) or $500,000 (married), the excess is taxable at federal long-term capital gains rates — 0%, 15%, or 20% depending on your income. New York State also taxes the excess at ordinary income rates.
If you do not meet the two-year requirements due to a job change, health issue, or other qualifying unforeseen circumstance, you may qualify for a partial exclusion proportional to the time you did live there.
Inherited properties receive a stepped-up basis — meaning your tax basis is the fair market value of the property at the date of the decedent's death, not the original purchase price. For Long Island families who inherited a home purchased decades ago for a fraction of its current value, this step-up can dramatically reduce or eliminate capital gains tax on sale.
Example: A home purchased in 1985 for $120,000, worth $750,000 at the date of death, and sold by the heirs for $800,000 — the heirs' basis is $750,000, not $120,000. The taxable gain is only $50,000, not $680,000. This is one of the most significant tax provisions affecting Long Island estate real estate.
New York State does not have a separate capital gains tax rate — gains from home sales are taxed as ordinary income at your New York State marginal rate. If you owe federal tax on a home sale, you generally owe New York State tax as well. Consult a New York tax professional for your specific situation.

Many primary-residence sellers qualify for the federal exclusion — up to $250,000 of gain if single or $500,000 if married filing jointly. New York taxes gains as income. Confirm your situation with a tax professional.
Inherited homes generally receive a stepped-up basis to the value at the date of death, which can significantly reduce taxable gain. Consult a tax advisor.
