Property tax snapshot
Typical property tax in Broomfield County
The average total mill levy across Broomfield County was about 113.7 mills for tax year 2023 — above the statewide average of about 81 mills. On a $500,000 home, that comes to roughly $3,731 a year, using Colorado's 2026 residential rules: 7.05% on school mills, and 6.8% on the rest after the local actual-value adjustment.
This is the county average across all tax areas. Your parcel's actual mill levy depends on its exact tax area — a metro or special district can add many mills on top — so confirm the real number with the county assessor.
Sales tax: the state charges 2.9% and Broomfield County adds no county sales tax — cities and special districts still can. See Colorado sales tax rates ->
