When can you protest a Polk County assessment?
Planning for the next assessment cycle
As of September 23, 2026, the regular 2026 protest window has closed. Iowa reassesses real property in odd-numbered years, making 2027 the next regular reassessment year. The dates below describe the standing calendar. Confirm the 2027 notice and county instructions before filing.
Informal assessor review
April 2 through April 25
Discuss the assessment with the assessor. A value change through this process requires a signed written agreement.
Board of Review protest
April 2 through April 30
File a formal protest if the value remains unresolved. Do not let an informal discussion carry you past the formal filing deadline.
These are the regular spring windows. Special notices and extensions can have different rules. Check the county's appeal instructions for your assessment year.
Build your case
Show what your home was worth on January 1
A higher bill alone does not establish an incorrect assessment. Focus on the property's value as of January 1 of the assessment year. Start with these records, then explain how each supports your requested value.
- Step 1
Check the property record
Save the assessor record and notice. Compare the listed size, age, features, and condition with your home. Document any factual errors.
- Step 2
Compare actual sales
Gather sales of similar homes, your own recent purchase documents, or an appraisal. Explain differences in location, size, condition, and features instead of relying on price alone.
- Step 3
Document condition
Use dated photos and inspection reports to explain problems a street view would miss. Tie the evidence to the home's condition on the assessment date.
For a Des Moines home, explain why each sale reflects the same local market. A similar floor area alone does not make a newer suburban home a good comparison for an older city home. Check the parcel's county before using this guide for a metro-area address.
See Iowa PAAB's evidence examplesHow to file a Polk County protest
Use the county's current petition and identify the parcel, assessment year, grounds for protest, and requested value. Sign it, include your contact information, and request an oral hearing in the petition if you want one. Each parcel needs its own form.
Polk County lists email, fax, mail, and delivery options. Follow the current instructions for your chosen method and keep proof of filing. The Board can leave the value unchanged, lower it, or raise it.
Open the county filing instructionsQuestions from Polk County homeowners
Is a property tax protest the same as disputing my tax bill?
A valuation protest challenges the assessment. Iowa's taxable value also reflects assessment limitations, and the bill depends on levies and applicable credits. A percentage reduction in assessed value does not guarantee the same percentage reduction in taxes.
Can I prepare before the 2027 notice arrives?
Yes. Organize your property record, purchase documents, photos, and potential comparable sales now. Once the new notice arrives, check its assessment year and value, then update your evidence and confirm the filing instructions.
Can I file a protest myself?
Yes. Homeowners can use the county's petition and file directly. If you prefer help, check your address with Homespring to see available support. An address check does not submit a county filing or reserve a deadline.
