Property tax in Hamilton County, New York

Who sends the property tax bill in Hamilton County, and how do you pay it?

The bill comes from your town's tax collector (each of Hamilton County's nine towns collects its own town and county bill). The value it is based on is set by a separate office, your town assessor (each of Hamilton County's nine towns prepares its own assessment roll), which is who to ask if the value looks wrong.

Hamilton County homeowners usually get at least two property tax bills a year. The town and county tax comes from your town's tax collector in January, and school taxes are billed and collected separately by the school district's collector, usually in September. The county does not assess homes: your town assessor sets values, takes exemption applications and hears the first appeal. There is no single county page for paying current taxes; each town sets its own payment options, and some, such as Inlet, take payments online. The county's Treasurer takes only delinquent taxes.

When are property taxes due in Hamilton County?

For the 2027 town and county taxes (bills issued in January 2027) bill, Hamilton County has one due date: January 31, 2027. New York law lets town and county taxes be paid without interest through January 31. January 31, 2027 is a Sunday, and state law automatically extends a tax deadline that falls on a weekend or holiday to the next business day, so the last day without interest is Monday, February 1, 2027. Towns applied the same rule in 2026: Lake Pleasant took payments without interest through Monday, February 2, 2026. Your town's notice, published in December, gives the exact date and office hours. Paid after the deadline, the bill carries 1% interest for February and another 1% for each further month. The town tax collector takes payments until unpaid taxes are returned to the Hamilton County Treasurer (in 2026 Lake Pleasant named April 1 as its last day); after that, delinquent taxes are paid to the County Treasurer, which accepts them online.

From Hamilton County's published schedule, checked September 23, 2026. The county had not posted a calendar labeled for this cycle when we checked, so these dates come from state law and the county's standing schedule; the date on your bill is the one that binds you.
