Installment due dates are always May 10th for the spring installment and November 10th for the fall installment. If the due date falls on a weekend, the due date will be the next business day after the weekend or holiday.
Under Indiana Law (IC.6-1.1-37-10), all payments received by the Treasurer's office AFTER that applicable installment’s due date are considered late UNLESS:
  1. Received by the Porter County Treasurer on or befor the due date; or
  2. Deposited in the United States First Class Mail, properly addressed to Porter County, with sufficient postage and legibly postmarked by USPS on or before the due date; or
  3. Your properly address payment is deposited with a nationally recognized express parcel carrier; verified by the express parcel carrier as paid in full for final delivery; and received by the express parcel carrier on or before the due date; or
  4. Deposited to be mailed through the US registered mail, US certified mail or US certificate of mailing, properly addressed to the Porter County Treasurer, with sufficient postage, and with a date of registration, certification or certificate, as evidenced by any record authenticated by the United States Postal Service, on or before the date due. PLEASE NOTE: We strongly discourage using US certificate of mailing as your payment envelope will not contain a post mark. If received after the due date, your payment will be processed as late and the account(s) will accrue penalties. Penalty will only be removed after the Treasurer’s office receives proof of on time US certificate of mailing. The taxpayer’s account will show online as having a delinquent penalty added and this cannot be removed from viewing.

Penalties will be applied if installments are not paid by the due dates. For more information about late tax payments and penalties visit Delinquent Taxes.
