Where to Pay Real Estate Taxes

You may pay your real estate taxes by mail, at the St. Clair County Treasurer's Office, or at many financial institutions (complete list below) throughout the county.   You can pay your taxes in person by cash, check, money order, or cashiers check. 

Credit Card, debit card, and electronic check payments may be made online.  We are unable to accept or process credit/debit or e-check payments in the office.  A convenience charge will be applied.  Credit Card transactions will be charged a fee of 2.5% or a minimum of $2.00. E-Check transactions will charge $2.00 for transactions up to $50,000.

The online system accepts Visa, MasterCard, Discover, and American Express.  You will need to access your parcel number and follow the payment links.  Payments are processed via our payment portal.

Online Payment Portal

Please note the online and telephone payment systems will be shut down at 3:00 p.m. on the last day to avoid publication through the remainder of that weekend and on the last day to pay to avoid tax sale.

Monthly Installments

The Treasurer's Office has initiated a monthly payment plan,  consisting of eight monthly payments, which all begin in September.  You may pay into an account on next year's taxes.

When bills are mailed you will receive credit for pre-payments and balances due will be shown on the payment stubs.

Monthly Installment Tax Registration Form

Monthly Installments may be automatically withdrawn from your bank account.
