Compare homesHow the tax bill is built
Boulder County says your property tax bill is based on actual value, the assessment rate set in state law, and mill levies from local taxing authorities such as school districts, cities, and fire districts. The county also says the 2024 temporary $55,000 value reduction ended for 2025 taxes payable in 2026, so some owners may see higher bills even if value barely changed.
