Property tax in Otsego County, New York

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

The bill comes from your town's tax collector, or in the City of Oneonta the city Finance Department, from January 1 through April 30; after April 30, the Otsego County Treasurer. The value it is based on is set by a separate office, your town or city assessor (each of Otsego County's towns and the City of Oneonta values its own properties and takes exemption applications), which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.

Otsego County homeowners can get up to three property tax bills a year: the town and county bill in January, a school tax bill from the school district, and a village tax bill for village residents. The county does not assess homes or take payment of current taxes: your town or city assessor sets values and takes exemption applications, and your town collector or the City of Oneonta collects the January bill until April 30. The county Treasurer's online payment site charges a card fee of 2.95% or $3.00, whichever is more; the town and city payment sites charge their own fees.

Late payments carry interest set by state law for each month after January. In the City of Oneonta that is 1% in February, 2% in March, and 3% plus a $1 fee in April. Towns and the city collect through April 30; taxes still unpaid then are turned over to the Otsego County Treasurer with additional fees and penalties. The Treasurer offers installment agreements for delinquent taxes of up to 12 months, with a down payment of no more than 25%, which you can sign from 30 days after the unpaid taxes are turned over until October 31 of that year. A payment more than 15 days late under an agreement adds a 5% late charge. The county holds an annual tax sale in August. No town or city official can waive interest, even if you never received a bill.
