How to Form a Corporation in Colorado

What you file in Colorado

This page covers the state filing and the charges that follow it. For the procedural side (name availability, registered agent, bylaws and the federal EIN), see the formation guide and how to get an EIN, both of which apply to corporations as well as LLCs.

What it costs to incorporate and stay filed

State filing charges only. Corporate income tax and franchise tax are excluded. Both depend on income or net worth, so no flat figure would be true for every corporation.

Colorado is the 3rd cheapest of 49 states on the incorporation filing fee alone. Nationally the fee runs from $35 in Montana to $300 in Texas, averaging $113.49. It is a one-off charge, so over five years it is usually outweighed by the recurring report fee and any annual franchise or minimum tax.

States that are cheaper to incorporate in

A cheaper filing fee elsewhere rarely saves money if you actually operate in Colorado. Every state sets its own threshold for what counts as transacting business, and where that threshold is met an out-of-state corporation is generally required to register as a foreign corporation. Which would mean fees in both states rather than one. Whether it applies to you depends on facts this page cannot see, so check foreign qualification in Colorado before incorporating elsewhere to save on the filing fee.

Colorado corporation vs Colorado LLC

State filing charges only. Corporate income tax and franchise tax are excluded because both depend on income or net worth, so no flat figure exists for either entity.

Both entities cost $50 to file in Colorado, so the filing fee is not a reason to pick one over the other.

State taxes a Colorado corporation pays

Colorado publishes no corporate franchise or gross-receipts tax.

What these totals leave out: the filing-charge figures on this page are what you pay the business filing office. They exclude corporate income tax and any franchise or gross-receipts tax, because both depend on income, net worth or receipts. The section above sets out what Colorado levies, or that it levies neither. Where a state's franchise tax carries a flat minimum, that minimum is an unavoidable annual cost these totals do not include, and over five years it can be the larger number.
