🏡 Utah Property Tax Appeals: September 15 Deadline Is Approaching
Utah homeowners who believe their property has been assessed at a value higher than its fair market value may still have time to appeal their 2026 valuation.
For most locally assessed residential property, the Utah State Tax Commission says the appeal deadline is generally September 15, or 45 days after the county’s valuation notice was mailed — whichever is later.
🔎 When Should You Consider an Appeal?
It may be worth reviewing your assessment if:
• Comparable properties suggest your home is worth less than the county’s valuation
• There are errors in your property’s characteristics or records
• The condition of your property has factors that affect its market value
• Recent market information does not support the assessed value
Utah property taxes are based on the property’s fair market value as of January 1 of the tax year, so evidence should generally address the property’s value as of that date.
📋 What Evidence Can Help?
Homeowners can strengthen an appeal by gathering:
✔️ Recent comparable sales
✔️ Documentation showing property-condition issues
✔️ Evidence of errors in the county’s property record
✔️ Other market information supporting a different value
You do not necessarily need a specific number of comparable sales. The important thing is to provide credible evidence supporting the market value you believe is appropriate.
📝 How the Process Works
The initial appeal is filed with your County Board of Equalization. The county reviews the evidence and issues a written decision.
If you disagree with the county’s decision, you generally have 30 days from the date of that decision to appeal to the Utah State Tax Commission.
⚠️ Don’t Wait Until the Last Minute
If you received a 2026 valuation notice and believe the value is too high, review it now and check your county’s filing instructions.
The September 15 deadline is approaching, but your specific deadline should be confirmed from your valuation notice or county assessor.
