The Town Clerk collects Town and County property taxes only. Tax bills are mailed out at the end of December and can be accepted online, via mail, or in person during Tax Collector office hours in the Town Office, penalty-free, from December 31st until January 31st. Tax bills paid after January 31st are subject to penalties- see your bill for exact amounts. The Town Office cannot collect tax payments after March 31st. However, we do accept payments with a USPS postmark of January 31st or earlier as "on time." Your tax bill can be viewed online at the Tax Glance link below as soon as our office receives and uploads your electronic tax bills from the Oswego County Office, which is not until the end of December.
I do not collect:
School Taxes
Village Taxes
Property Taxes outside my window of collection- After March 31, delinquent taxes are paid to the Oswego County Treasurer.
Ways to Pay:
Cash
Check/Money Order payable to "Nicole Wild, Tax Collector"
Credit/Debit/E-Check*
-In person during our Tax Collector Business Hours
-Drop payments securely in our Drop Box located directly to the left of our front door entrance
-Online at the Williamson Law Book Tax Glance payment portal link below
-Mail checks or money orders made out to "Nicole Wild, Tax Collector" to Tax Collector, PO Box 272, Mexico, NY 13114
*We offer a payment option by credit card as a convenience to our residents. Unfortunately, due to processing fees which are beyond our control, there is a $1.75 or 3% processing fee for all credit/debit card transactions (whichever is higher) and a flat $2.50 processing fee for all e-check payments. This fee is not determined by the town nor is it revenue for the town.
