This office would require you to complete an affidavit, have it notarized and return the original affidavit to us. You must also notify us upon your return to civilian life.

Overpayments

If you send a payment for more than the total tax amount due, we will attempt to reach you for instructions.  If we make no contact, your overpayment will be refunded. The refund will be issued to the check maker approximately four weeks after the date of deposit which is our standard procedure.

Should you have any additional questions, please contact this office at 630-407-5900.

Duplicate Payments

Duplicate payments occur when multiple tax payments have been made for the same property parcel number. The Treasurer's Office will notify the assessee of record at the time the multiple payment was created.

Often, when refinancing or selling property, a loan or title company, as well as the former mortgage company, will pay the tax. Sometimes individuals will pay the tax upon receiving the tax bill, not realizing that their taxes are escrowed by their mortgage company. These situations will result in a double payment.

A refund may only be obtained by the taxpayer who actually made the duplicate payment. To initiate the refund process, that taxpayer must complete an affidavit (PDF), have the form notarized, and return it to this office at 421 N. County Farm Road, Wheaton, IL 60187-2553.  

We also require a legible copy of the proof of payment showing the funds debited from the account. A cash receipt or receipt copy of a cashier's check is also acceptable as proof of payment.  If you paid online, we require a copy of your bank statement showing the debit from your account.

If you, as the homeowner, did NOT make the duplicate payment, please notify your mortgage or loan company so they can determine if they should claim the refund of the duplicate payment.

If you have any questions about the duplicate payment refund procedure or your situation regarding a duplicate payment, please do not hesitate to call this office at 630-407-5900 during our normal business hours 8 a.m.- 4:30 p.m. Monday - Friday.
