Utah Property Tax Appeal Guide
How to challenge your property tax assessment in Utah - deadlines, process, and a savings calculator.
What This Data Tells Us About Appeals in Utah
- Administrative filing in Utah is listed at $0, so the first barrier is evidence and timing, not a petition fee.
- This ACS extract does not store how often Utah assessments are reduced on appeal; comparable sales and property-record errors are the evidence the named board typically asks for.
- The typical window centers on September; confirm the current county notice date before relying on the statewide summary. Compare Mississippi's September window before assuming Utah is early or late.

September 15 deadline. Deadlines can vary by county and assessment cycle, so confirm the current date with the local assessor before relying on this guide.
Decision signal 4
This extract does not store an appeal-win rate
The ACS county medians on this site do not include how often Utah assessments are reduced on appeal. Recent comparable sales and documented property-record errors are the evidence boards typically ask for.
How to read this guide and disclaimer
Use the ranked signals above as a preparation order, not as a forecast. Start with the filing window and named appeal body because a strong valuation argument cannot cure a missed deadline or a filing sent to the wrong office. Then compare the assessment with recent, genuinely similar properties and document factual errors such as incorrect square footage, condition, or classification.
An estimated success rate is not part of this ACS extract. Keep copies of the assessment notice, evidence, forms, delivery confirmation, and every response from the taxing authority. If a state rule and a county instruction differ, follow the current instruction issued by the office that will hear the appeal.
This guide is for informational purposes only and is not legal or tax advice. Deadlines, filing fees, and procedures vary by county within Utah and can change year to year. Always verify the current rules with your local assessor's office, or a licensed attorney or tax professional, before filing. Source: Utah State Tax Commission.
