Late Interest Failure to receive a tax statement is not a defense to the payment of the tax and any late interest that has accrued. Iowa law requires the Treasurer to assess late interest on all delinquent payments at the rate of 1.5% per month, rounded to the nearest dollar. The U.S. Postal Service postmark is the only date recognized for date of mailing. We do not accept the date written on your check or a business metered date as proof of the mailing date. Before mailing your payment, check with your local post office to make sure the postmark date will be prior to the late interest date. If you want to be sure that your payment has a postmark before the late interest date, have the post office postmark the envelope in your presence.
Annual Tax Statements Annual tax statements are mailed once a year in the month of August. The tax statement has two detachable payment stubs.
Your property tax may be paid in full or in two installments. The first half is due on September 1 and becomes delinquent after September 30. The second half is due March 1 and becomes delinquent after March 31.
If you have not received a tax statement, please contact the Treasurer's office for a duplicate statement at 515-832-9542.
