How it works
How to protest your property taxes in Polk County.
- Step 1

- Step 2
Order the appraisal
A desktop appraisal valued as of your assessment date, with the $5 credited. Complex homes get one exact quote.
- Step 3
Show us your home
Walk through on your phone so the appraiser sees its condition. A desktop appraisal needs no visit.

File your protest
A state-licensed IA appraiser signs it, with a cover letter and filing steps. You file by your deadline, and the local Board of Review hears your case.
The evidence
Boards act on value, not frustration.
However Iowa labels the process, the case underneath is the same: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal, with comparable sales, documented adjustments and a signed opinion of value, is that showing.

The process
How Iowa handles protests.
Iowa assessors (some cities have their own; otherwise the county) revalue property in odd-numbered years, with notices arriving by April 1. Protests are filed with the local Board of Review between April 2 and April 30 — one of the country’s cleanest statewide windows — and the board rules in May. From there, homeowners can take the case to the state Property Assessment Appeal Board (PAAB) in Des Moines or to district court; PAAB is free to file and built for exactly this. Boards respond to grounds and evidence: the classic ground is that the assessment exceeds market value, proven with comparable sales as of January 1 — the substance of a licensed appraisal.
Polk County guidance
An owner or aggrieved taxpayer files a protest with the Polk County Board of Review. The Assessor office supplies forms and receives filings; the Board hears the formal protest. Confirm current submission instructions before filing.
Worth knowing in Iowa
Iowa applies a statewide “rollback” (assessment limitation) before taxes are computed, so your taxable value is a fraction of assessed value — the protest still targets the assessed (market) number. In even years you can protest too, typically on the ground that value has changed since the reassessment.
