Larimer County property tax appeals

Colorado sets your actual value and reappraises in odd years. You protest to the county assessor in the spring, with objections due by about June 8, then appeal to the county board of equalization. An appeal helps when your value is above what your home would sell for.
- Your actual value is above what your home would sell for during the assessor’s study period.
- The record has an error in your home’s size, condition, or features.
- You protest to the county assessor by about June 8, then appeal to the county board of equalization.
- Your bill went up but your value is fair. A higher bill often comes from the mill levy, not the value.
- You have no market evidence. The protest reviews your value, not the size of your bill.
Read the full explanation
In Colorado, your county assessor sets your home’s actual value, and you protest that value in the spring. Colorado reappraises in odd years, so a reappraisal value carries into the next even year unless your property changed. You protest to the county assessor by early June, then appeal to the county board of equalization. An appeal helps when your actual value is above what your home would sell for during the assessor’s study period, or the record has an error. It usually will not help just because your bill went up. This is general information, not tax advice.

- Filing window:
- Protest your actual value to the county assessor in the spring, with objections due by about June 8 (the next business day if that is a weekend). If the assessor denies you, appeal to the county board of equalization. Colorado reappraises in odd years, so in an even year mainly properties that changed value get a new notice.
