Flat 4.4% state income tax
A single flat rate applies to all taxable income, simplifying owner-level projections on pass-through business income compared to bracket-based states.
Home-rule cities file sales tax separately
The state rate is just 2.9%, but dozens of home-rule cities — Denver, Aurora, and Colorado Springs among them — collect and administer their own sales tax independently. Selling into those cities can mean a separate registration and filing per city, not one combined return.
Periodic Report due every year, no exceptions
Colorado requires a $25 Periodic Report every year for the life of the LLC, even in a year with zero income or activity — missing it puts the LLC out of good standing.
Frequently asked questions
What's Colorado's state income tax rate for a small business?
Colorado uses a flat state income tax rate of 4.4% for 2026, applied to all taxable income rather than brackets.
Why is Colorado sales tax more complicated than the state rate suggests?
Colorado's state sales tax rate is only 2.9%, but dozens of 'home-rule' cities — including Denver, Aurora, and Colorado Springs — administer their own sales tax separately from the state. Selling into those cities can mean registering and filing directly with each city in addition to the state, not just paying one combined rate.
Does a Colorado LLC need to file anything every year?
Yes. Every Colorado LLC must file a Periodic Report with the Secretary of State each year and pay a $25 fee to stay in good standing — required every year regardless of income or business activity, even for an LLC that did nothing that year.
How is an LLC formed in Colorado?
A Colorado LLC is formed by filing Articles of Organization with the Colorado Secretary of State. After formation, an EIN, registered agent, and the first Periodic Report all need to be set up on schedule to avoid falling out of good standing.
