Learn moreA genuinely low effective property tax rate
Broomfield County's effective property tax rate is cited at 0.62%, with a median annual bill of $3,888 on a home valued at $631,600 (Tax-Rates.org, Ownwell, City and County of Broomfield official Property Tax 101 page, retrieved 2026-08-24) -- consistent with Colorado's roughly 0.50% statewide average and genuinely low relative to Broomfield's comparatively high home values. The exact rate varies by address given overlapping school, fire, library, and metropolitan special-taxing districts.
Sales tax genuinely varies by specific address
The combined sales tax rate ranges from 8.15% (city and county combined, no special district) up to 9.11% in areas layered with additional special-district taxes -- 2.90% Colorado state + 4.15% City and County of Broomfield, with the remainder from county/special-district add-ons (Avalara, SalesTaxHandbook, City of Broomfield official Sales Tax page, retrieved 2026-08-24).
Colorado's flat state income tax, restated at the city level
Colorado's flat individual income tax rate is 4.40% for tax year 2026, subject to a TABOR-driven surplus mechanism that can temporarily lower it (as it did for tax year 2024) -- a statewide fact, not a Broomfield-specific one, restated here as place-level context (Colorado Dept. of Revenue, same basis as colorado.js).
Front Range 'Hail Alley' homeowners insurance exposure
Broomfield sits inside the Front Range "Hail Alley" corridor documented at the state level -- Colorado is cited as having the 4th-highest average homeowners premium in the nation, up roughly 100.8% over the five years preceding this research, driven primarily by severe, recurring hail risk, with statewide premium estimates ranging from roughly $3,200 to $4,600/year depending on methodology (colorado.js, same source basis). Broomfield's proximity to the Boulder County wildland-urban-interface corridor -- including the December 2021 Marshall Fire's Superior/Louisville footprint -- adds real, disclosed wildfire-risk exposure on top of hail.
