Clean books for Denver businesses — RiNo makers to aerospace suppliers — that keep up with Colorado's home-rule sales tax and the Denver OPT.
Denver leads major US metros in private aerospace employment, with a strong outdoor-recreation and gear scene alongside tech, construction, and professional services. Colorado is home to 715,000+ small businesses, and Denver ranks among the top metros to start one. LedgerHelm keeps those books clean through Colorado's uniquely fragmented tax landscape.
We sell across Denver, Aurora, and Boulder — three separate home-rule city sales-tax filings.

Inventory, COGS, and clean monthly books.
Project costing and investor-ready financials.

Colorado taxes individuals and corporations at a flat 4.40%. We keep clean books so estimated payments are easy to plan.
Denver self-collects its own sales/use tax separately from the state, so you file a Denver city return on top of the Colorado return — and selling into Aurora or Boulder can add more city filings.
Denver's monthly “head tax” applies to each employee earning $500+ for work in the city — $5.75 employee + $4.00 employer per head, even for out-of-city employers.
Colorado entities file an annual Periodic Report ($25) with the Secretary of State around their formation anniversary to stay in good standing.
