Sullivan Delinquent Taxes Route Through the Treasurer

Sullivan County gives delinquent county and town taxpayers a lookup route, but payment is not self-serve inside the lookup. Delinquent county and town taxes can be viewed online. They can then be paid directly to the Treasurer by check, money order, in person, or by calling the office for card payment. Installment agreements are a separate county route.

Installment agreements apply to county and town taxes, not village taxes. Confirm the parcel, tax year, current balance, and payment route with the Treasurer before mailing money. Keep the lookup, bill, agreement if any, and each receipt together.
