If an Oswego County property-tax bill has gone delinquent, the early move is to find the right enforcing office and balance. Treasurer’s property-tax materials say that after March 31, town/county taxes are sent to the Oswego County Treasurer’s Office for collection. It includes a 5% fee when transferred, subject to the half-payment timing explained on the page.
The installment-contract page says a person seeking an agreement contacts the Treasurer to obtain the outstanding balance and the initial 25% down-payment requirement. All delinquent parcels must be included.
Keep the bill, parcel list, outstanding balance, 5% transfer fee, down-payment figure, proposed agreement, and every payment receipt together. Confirm the current terms with the Treasurer before sending money.
