Sales & use tax
8.2% combined per DR1002 (state 2.9% + Garfield County 1% + Roaring Fork Regional Transportation Authority 0.80% within Basalt/New Castle city limits + Town of New Castle 3.50%). New Castle is state-collected (listed in DR1002's state-collected-towns table, not the home-rule table): "New Castle Garfield 3.50% 3.33% [use tax] 2% Building Materials." That 2% town use-tax rate on Building Materials specifically is the roofing-relevant figure. Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
