$
Effective rate 1.04% = this county's median owner-occupied tax bill ($4,984, ACS 2022 5-year estimate) divided by the typical home value at the time ($480,391, Zillow, 2022-12-31). Exemptions the seller holds — homestead, senior, veteran — usually do not transfer with the deed, so a new purchase can run above this figure. The county assessor sets the assessed value; this is an estimate, not a quote.
If you pay late
If payment is made after the grace period, interest is charged from the original due date and compounds daily.
NYC fiscal year runs July 1 to June 30; bills are mailed about a month before each due date, quarterly, or semiannually above $250,000 assessed value. If a due date lands on a weekend or public holiday, most counties move it to the next business day — check the county's own notice before relying on the shift.
By post: mail a cheque to the treasurer's office; the postmark date usually counts, not the arrival date.
In person: the treasurer's office during business hours; bring your bill or parcel number.
Mortgage escrow: if your taxes are escrowed, the servicer pays — you still owe the difference if your escrow is short.
