Sales & use tax
6.375% combined in unincorporated Summit County (state 2.9% + county 2.0% + Summit County Mass Transportation System (Summit Stage) 0.75% + Multi-Jurisdictional (affordable) Housing Authority 0.725%). Always state-collected — the County's own page states: "A sales tax license is not needed from the county. This is obtained from the State because the State of Colorado Department of Revenue collects all county and mass transit taxes." No county-level construction-materials use tax was found (the County's own page describes only "sales tax and mass transit tax," no use tax); consistent with Breckenridge's own explicit statement that Summit-area use tax does not exist.
