Pursuant to Illinois Compiled Statutes (Ch. 200/21-355), tax buyers may pay unpaid taxes of a subsequently occurring tax sale (sub-tax) on any parcels they have purchased at a previous Will County tax sale and add the tax amount to their sale certificate. Statutorily, we may only accept sub-tax payments (1) after the second installment becomes delinquent or (2) after the holder of the certificate of purchase has filed a petition for tax deed with the Court. This office will not produce subsequent tax bills. It is the responsibility of the tax buyer to either request copies for a fee or go online and print copies of the bill. The cost to have this office produce copies of the bill will be $5.00 per bill. To print copies of the bill Click Here. Please note the indemnity fee will not be listed on the bill. There is a $30.00 indemnity/automation fee added to each property index number being paid. It is the tax buyer’s responsibility to check for prior year redemption on each property index number before submitting a sub-tax payment. It is the responsibility of the tax buyer to insure the sub-tax payment is posted by the Will County Clerk’s office. Please contact the Clerk’s office at (815) 724-1880 for more information. The date that your sub-tax payment is posted in our office will be used for computing penalty. On the first of each month, additional penalty of 1.5% per installment must be added to your payment.
