How Property Tax Works

Kings County, New York (also known as Brooklyn), operates under New York City's unified property tax system, which serves as the primary funding mechanism for essential municipal services including public schools, police and fire departments, parks, libraries, and infrastructure maintenance. The NYC Department of Finance administers property tax assessment and collection for all five boroughs, including Kings County, ensuring consistent application of tax laws and exemption programs across the city.

Property taxes in Kings County are calculated based on the market value of real estate, with an effective tax rate of approximately 10.762% for the 2025-26 tax year applied to the assessed value. The assessment process considers factors such as property type, size, location, and recent comparable sales. Kings County property owners benefit from various exemption programs including the STAR program for school tax relief, senior citizen exemptions, and veterans exemptions, which can significantly reduce the overall tax burden for qualifying homeowners.

When Are Property Taxes Due?

For the 2025/2026 tax year in Kings County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Kings County are triggered by specific events that change a property's assessment during the tax year, primarily including change of ownership, new construction completion, or major renovations that add significant value. When these events occur, the NYC Department of Finance issues a supplemental assessment to capture the difference between the old and new assessed values for the remainder of the tax year.

The supplemental tax is calculated by taking the difference between the new assessed value and the previous assessed value, multiplying by the current tax rate (10.762%), and prorating for the remaining months in the tax year. For example, if a property's assessed value increases by $50,000 due to completed renovations in January, the supplemental tax would be approximately $5,381 ($50,000 × 10.762%) for the full year. Property owners typically receive supplemental tax bills within 30-60 days of the triggering event and have the same payment options as regular property tax bills.

Escrow & Property Taxes

Most Kings County homeowners with mortgages have their property taxes collected through escrow accounts managed by their mortgage servicer. Lenders typically collect 1/12th of the annual tax bill with each monthly mortgage payment, holding these funds in a separate escrow account to ensure timely tax payments. The servicer pays property taxes directly to the NYC Department of Finance when bills are due, usually in quarterly installments throughout the tax year.

Property owners should verify that their mortgage company has current tax information and is making payments on time by checking their annual escrow analysis statement and monitoring their account through the NYC Department of Finance website. If you pay taxes directly without escrow, you can make payments online, by phone, mail, or in person using the official payment portal at https://www1.nyc.gov/site/finance/pay-now/pay-now.page. Late payments incur interest charges and potential penalties, so maintaining accurate escrow funding or making direct payments by due dates is essential for avoiding additional costs.
