Who we serve in Denver

Outdoor & recreation brands

Inventory, COGS, and clean monthly books.

Aerospace & tech suppliers

Project costing and investor-ready financials.

Multi-city retailers & services

Home-rule sales-tax filing across the metro's cities.

Local tax & compliance

Bookkeeping built around Denver, CO tax rules

Colorado flat income tax

Colorado taxes individuals and corporations at a flat 4.40%. We keep clean books so estimated payments are easy to plan.

Home-rule sales tax

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.

Occupational Privilege Tax (OPT)

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.

Periodic Report

Colorado entities file an annual Periodic Report ($25) with the Secretary of State around their formation anniversary to stay in good standing.

FAQ

Denver, CO bookkeeping — FAQ

How does Colorado's home-rule sales tax work for a Denver business?
Denver self-collects its own sales/use tax, so you file a separate city return on top of the state's — and selling into Aurora, Boulder, or Lakewood can mean multiple city filings. LedgerHelm keeps your sales-tax data organized by jurisdiction so nothing is missed.
What is the Denver Occupational Privilege Tax (OPT)?
Denver's OPT (a monthly 'head tax') applies to each employee earning $500+ for work performed in Denver — $5.75 employee + $4.00 employer per head — even for businesses based outside the city. We help you keep the payroll data to file it correctly.
Does Colorado require an annual business filing?
Yes — a Periodic Report ($25) to the Secretary of State each year around your formation-anniversary month keeps your entity in good standing. We track the window for you.
What's Colorado's income tax rate?
A flat 4.40% for both individuals and corporations. Clean, current books make quarterly estimated payments simple to plan — LedgerHelm keeps them that way.
