Will My Property Taxes Be the Same as the Seller’s?

Do not assume that the annual tax figure in a listing will become your permanent bill. First identify the tax year, the source of the number, the benefits included and the actual property or unit it covers.

Three figures answer different questions: a sale price is what the parties agree to pay; an assessment is a value used in the tax system; a bill is the amount charged after applicable calculations and adjustments. A lower assessment does not, by itself, tell you the next bill.

New buyers should check New York’s STAR registration guidance rather than assume the seller’s benefit transfers. The NYC co-op/condo abatement has separate ownership and primary-residence requirements and is administered through the building’s application process. These are different benefits, not interchangeable discounts. New York Tax — New homebuyers · NYC Finance — Cooperative and Condominium Tax Abatement

Request a written answer to four questions: Which benefits are in today’s bill? Which depend on the owner or occupancy? Which expire or change? Who must apply, and by when? For a co-op, ask how any benefit is reflected in your building charges or credit.

Do not let a salesperson fill missing figures with zero. For new construction, ask which figures are estimates and what written material supports them. For Nassau or Suffolk, use the relevant local assessment and tax offices rather than importing an NYC rate or benefit.

As checked on October 23, 2026, NYC Finance describes an annual surcharge for certain non-primary residences. For 2026–27 and 2027–28, the stated thresholds differ for houses and condo/co-op units and use DOF values, not purchase prices. Primary-residence exceptions may apply, including qualifying tenant occupancy. This is not the transfer-time mansion tax. Review the current notice with your attorney or tax adviser.

Does a $1 million purchase automatically trigger this annual surcharge? No conclusion should be drawn from the purchase price alone. Check the property type, DOF valuation, occupancy and applicable rules.

Save the listing’s tax figure, the latest bill and any benefit notices together. Ask B Square Realty to help organize the property questions; have the relevant tax office, managing agent and adviser verify eligibility and future estimates.

Is the mansion tax an annual property tax? No. Keep purchase-related transfer taxes and recurring ownership taxes in separate parts of your budget.
