Mailing address

What Happens If Polk County Property Taxes Are Late?
Polk County states that late interest is charged at 1.5% per month, rounded to the nearest dollar, with a minimum charge of one dollar. Late interest is added to the unpaid property-tax balance.
The first installment begins accruing late interest on October 1 when not paid within the September payment period. The second begins accruing late interest on April 1 when not paid within the March payment period.
Tax-sale risk
Property taxes that remain unpaid can become subject to the county’s annual tax-sale process. A tax-sale certificate can create a lien against the property, and unresolved tax-sale obligations can eventually create much more serious ownership consequences.
The Treasurer’s appointment system includes a property-tax service option for paying property tax and redeeming a tax sale.
When to Contact the Treasurer—and When Not To

- Payment status and receipts
- Late or delinquent taxes
- Tax-sale redemption questions
- Property-tax payment methods

- Questions about how a value was calculated
The Treasurer collects taxes after property values and tax obligations have been established through the applicable assessment and taxing process. Paying the Treasurer does not itself correct an assessment or ownership-record problem.
Property Tax Credit Program
The Polk County Treasurer also administers the Iowa Property Tax Credit Program locally. Eligibility and application rules are separate from simply paying a regular property-tax bill, so use current state and county guidance before assuming a credit applies to your account.
Common Polk County Property Tax Problems
Recheck the parcel number and owner name. If the property still does not appear, call the Property Tax Division rather than paying an account that only looks similar.
Check whether your bank or escrow company is responsible before making a duplicate payment. The online system may display an escrow-related message.
Polk County states that property owners remain responsible for ensuring taxes are paid on time even if a statement was not received. Contact the Treasurer promptly.
Keep the confirmation number, bank record, check information, parcel number and payment date. Contact the Treasurer before submitting a second payment.
Polk County allows certain partial payments for current or delinquent real-estate and mobile-home taxes when county conditions are met. Special assessments and tax-sale redemption payments have different rules.
A valuation dispute is not solved by changing the payment amount yourself. Use the appropriate assessment authority and appeal process.
