Yuma County property tax appeals
Your deadline runs from the date on your assessment notice.
Appeals go to Yuma County Assessor (first level), then the Arizona State Board of Equalization.
Arizona gives your home a full cash value and a growth-capped limited property value. Your tax is based on the limited value, so an appeal of full cash value often will not lower your bill. You appeal to the county assessor within 60 days of your notice of valuation.
- Your full cash value is clearly higher than what your home would sell for, and it sits at or below your limited property value.
- Your property is in the wrong classification, or the record has an error in size, condition, or features.
- You file with the county assessor within 60 days of the date your notice of valuation was mailed.
- Your tax follows the capped limited property value, which stays below full cash value for most owners, so lowering full cash value changes nothing.
- You have no evidence your full cash value is wrong. The appeal reviews your value, not the size of your bill.
Read the full explanation
In Arizona, the county assessor gives your home two values each year: a full cash value, which is roughly market value, and a limited property value, which by law can rise only a small amount a year. Your property tax is calculated on the limited property value, so it usually will not drop even if you win a lower full cash value. You appeal the full cash value or your property classification to the county assessor within 60 days of the date your notice of valuation was mailed, and then to the State Board of Equalization or tax court. An appeal helps most when your full cash value is clearly too high or your property is misclassified. It often will not lower your bill, because your tax follows the capped limited value, not the market value. This is general information, not tax advice.
