What Is a Protest
A protest is a formal written objection filed with your local assessor's office challenging the assessed value of your property. Unlike an appeal, which is filed after a protest is denied, a protest is your first step to dispute the assessment before it becomes final.
Most jurisdictions require you to file a protest within 30 to 45 days of receiving your assessment notice. Missing this deadline typically bars you from appealing to the board of review, so timing is critical. Some counties allow protests to be filed online through their assessor portal, while others require in-person submission or certified mail.
What You Need to File
A valid protest must include specific information to be considered. Most assessors require:
- Your property identification number (PIN) or parcel number
- The current assessed value you are challenging
- The value you believe is correct
- Your reason for protesting, such as unequal assessment or incorrect appraisal method
- Supporting documentation, which typically includes comparable sales data, property condition photos, or recent appraisals
The assessor then reviews your protest and either adjusts the assessment or denies it. This review period usually takes 30 to 60 days. If denied, you can proceed to a board of review hearing where a panel of local officials hears your case.
Evidence That Works in Protests
Comparable sales (comps) are the strongest evidence in a property tax protest. Provide 3 to 5 recent sales of similar properties in your area sold within the past 12 months. Include the sale price, date, property features, and square footage. If your assessed value exceeds comparable sales by 10 to 15 percent or more, you have a solid case for overvaluation.
Assessment ratios matter here. If your township assesses residential properties at 50 percent of market value but your assessment runs at 65 percent, you can argue unequal assessment. Request your assessor's published assessment ratio from the state tax commission.
Income approach appraisals work well for rental properties or commercial spaces. Show rental income, vacancy rates, and cap rate calculations that support a lower value than the assessor's estimate.
Common Questions
- Can I protest even if I think the assessment is only slightly high? Yes. Many successful protests result in 5 to 10 percent reductions. A 5 percent reduction on a property assessed at $300,000 saves $150 per year in taxes, which compounds annually.
- What if the assessor requests additional information after I file? Respond promptly. Many protests are denied simply because owners don't provide follow-up documentation within the requested timeframe.
- Does filing a protest increase the risk of reassessment? No. Most states prohibit assessors from raising assessments in retaliation for a filed protest. Check your state's property tax statutes to confirm this protection applies in your jurisdiction.
