Property Tax Deadlines: Don’t Miss New York City’s April 1/15 Due Dates

Paying your property taxes on time isn’t just a civic duty—it helps fund public schools, police, parks and other services that make New York a great place to live. Missing a deadline can lead to interest charges and penalties, so understanding how New York City bills homeowners is essential. Below, you’ll find a detailed overview of the April 1 deadline and the April 15 grace period, plus tips to keep you on track.

How NYC Property Tax Billing Works

New York City sends property‑tax bills either semi‑annually or quarterly, depending on a property’s assessed value:

  • Assessed value over $250,000 – billed semi‑annually. Bills are due on July 1 and January 1.
  • Assessed value $250,000 or less – billed quarterly. Bills are due on January 1, April 1, July 1 and October 1.
  • If your due date or grace period falls on a weekend or holiday, the payment is due on the next business day.

    The grace period

    Quarterly payers receive a 15‑day, interest‑free grace period. You won’t be charged interest for payments postmarked as late as January 15, April 15, July 15 or October 15. This grace period gives homeowners extra time to send payment without incurring penalties.

    April’s Deadlines: April 1 and April 15

    The City’s finance calendar shows that 4th‑quarter property tax installments for homes assessed at $250,000 or less are due on April 1. If you pay quarterly, your payment must be postmarked no later than April 15 to avoid interest charges. Here’s what that means:

  • April 1 – Official due date for the fourth‑quarter property‑tax bill.
  • April 15 – Last day of the grace period. Payments postmarked by this date are considered on time.
  • After April 15 – Interest begins accruing on unpaid balances. Late payments accrue daily interest; the rate for 2025‑2026 is 6 % for homes valued under $250,000 and can reach 16 % for high‑value properties.
  • Early Payment Discounts

    Homeowners who pay early may qualify for small discounts. According to NYC311, paying the full annual amount by July 15 yields a 0.5 % discount, and smaller discounts apply for October 15 (0.25 %) and January 15 (0.125 %) prepayments. Semi‑annual payers receive a 0.5 % discount if they pay the entire tax year by July 1.

    Late Payment Penalties

    A payment is considered late if it’s not postmarked by the due date or grace period. The Department of Finance is legally required to charge interest on the outstanding amount until it is paid. Interest compounds daily and can add up quickly, so avoid procrastination.

    Ways to Pay

    The City encourages online payments through CityPay, but you can also pay:

  • By electronic funds transfer or through your bank’s bill‑pay system.
  • Over the phone, by mail, or in person at a Department of Finance business center.
  • Through monthly advance payments—a program that lets you pay in smaller installments. Monthly payments are withdrawn automatically on the 1st of each month, and you must be current on existing taxes to enroll.
  • Tips for Staying on Track
    Mark your calendar. Set reminders for April 1 and April 15 (or the next business day if they fall on a weekend) so you don’t forget.
    Review your assessed value. Check the assessed value of your property to see whether you’re a quarterly or semi‑annual payer. If your assessed value increases above $250,000, your billing schedule changes.
    Use the grace period wisely. The 15‑day grace period is a buffer, not an extension. Plan to pay early to avoid postal delays and reduce stress.
    Consider monthly payments. For consistent budgeting, the monthly advance payment option spreads your tax bill into smaller, automated payments.
    Update your contact information. Make sure the Department of Finance has your current address so you receive bills and notices on time.
