One combined bill. It includes county tax + town tax + school tax + special districts on a single invoice issued December 1. You can pay it in two halves (first half by January 10, second half by May 10) without penalty.
The tax sale typically happens in November-December of the year following the bill. To avoid the sale, pay by sometime in October of that year — but verify the exact deadline with the County Comptroller, since penalties keep accruing.
You should verify each year. Some mortgage servicers pay late or miss the second half. Check your escrow analysis statement and confirm the County recorded the payment.
