How to Start an LLC in Colorado (2026)
Colorado is genuinely one of the cheapest, fastest states to form an LLC — just $50 filed online with instant approval, no franchise tax, and a flat $25 annual report. This guide walks all 8 steps, with a cost calculator and the honest details other guides skip.
It costs $50 to file Colorado's Articles of Organization — online only, with approval typically instant. There's no separate franchise tax; instead, every LLC files a Periodic Report once a year during its anniversary month for a flat $25. Colorado's flat 4.4% state income tax is among the more moderate rates nationally, and there's no minimum tax or gross receipts tax layered on top.

Why Form an LLC in Colorado?
Colorado is a genuinely strong choice for cost-conscious founders — the numbers stack up in your favor from day one:
- $50 filing fee, instant approval — Colorado only accepts online filings, but that means no waiting; most Articles of Organization are approved within minutes.
- No franchise tax — unlike states that charge LLCs a minimum tax regardless of profit, Colorado's only recurring state fee is the $25 Periodic Report.
- Flat 4.4% state income tax — no brackets to calculate, and the rate applies the same whether you earn $30,000 or $3 million.
- No name reservation required — your name is reviewed and approved for free the moment your Articles of Organization is filed.
- No general state business license — Colorado doesn't require a blanket state license, though local and industry-specific ones may still apply.
Colorado's home-rule cities complicate sales taxColorado has more "home-rule" municipalities than almost any other state — cities like Denver, Boulder, and Colorado Springs administer their own sales tax entirely separately from the state. If you sell taxable goods across multiple Colorado cities, you may need to register and file with each one individually, not just the state. See Step 7 for the full picture.

Colorado's Flat State Income Tax
Colorado uses a flat 4.4% income tax rate — moderate by national standards, and refreshingly simple since there are no brackets to work through. As a default pass-through LLC, your share of profits flows to your personal return, where it's taxed federally and at Colorado's flat rate; there's no separate entity-level income tax to worry about beyond the flat $25 Periodic Report. Colorado is also a TABOR (Taxpayer's Bill of Rights) state, meaning revenue surpluses can trigger future rate adjustments — worth checking each year. We break the full picture down, with an estimator, in Step 8: Colorado LLC Taxes.
Colorado only accepts online filingsUnlike most states, Colorado has fully discontinued paper filing for Articles of Organization and most standard LLC transactions — everything runs through the Secretary of State's online eCorp portal. The upside: no mail delays, and most filings are approved within minutes rather than days. See Step 3 for the full filing walkthrough.
