Colorado

Colorado state tax filings.

Which agencies Colorado uses, which forms they take, and what Colorado does differently. Every entry carries the date it was checked against the agency's own material.

Who you deal with in Colorado

Colorado Department of Revenue

The state sales tax license, covering state and state-administered jurisdictions only

MyBizColorado, then Revenue Online

Colorado Department of Labor and Employment

Unemployment insurance, and separately the FAMLI paid family and medical leave program

MyUI Employer+

Home-rule cities, each licensing separately

Their own city sales tax license, which the state license does not provide. The Department publishes the list of home-rule cities as DR 1002

Each city's own system

3 separate agencies, on 3 separate systems. Doing something with one does nothing to the others.

What Colorado does differently

  • One registration, two closures. A single Colorado application registers you for both Department of Revenue wage withholding and Department of Labor and Employment unemployment insurance. Nothing closes them together. That asymmetry is the whole problem with Colorado, and it catches people who did the registration themselves and remember how easy it was.
  • The notice goes in two places. Colorado wants the closure request, and it also wants the final return to say the business is closing with the effective date on it. Doing one and not the other leaves a mismatch the department has to resolve.
  • There is a third account and it is easy to miss. FAMLI, the Family and Medical Leave Insurance program, sits alongside unemployment at Labor and Employment. A business that sets up withholding and unemployment and stops there has two of the three.
  • The fee depends on when you apply, and there is a deposit nobody mentions. Colorado prorates against the two-year cycle, so the same license is $16, $12, $8 or $4 depending on the half-year you file in. A new account also owes a $50 deposit with the CR 0100. Quotes that name a single Colorado license fee are quoting one cell of a four-cell table and leaving out the deposit.
