Can a non-US founder open a Mercury account with a Colorado LLC?

Yes. Mercury explicitly supports foreign founders with a US LLC. You need the Colorado formation document (the Articles of Organization), the IRS EIN letter, a non-US passport for identity, and a US business address. No US SSN or residency is required.

Does forming in Colorado affect Mercury eligibility?

No. Mercury accepts LLCs from all US states and territories. The formation document name varies by state, and Colorado issues Articles of Organization; Mercury accepts it the same as any other state's.

What does the Colorado LLC itself cost before I can start taking payments through Mercury?

Colorado charges $50 to file Articles of Organization, and that is the state's fee to create the LLC. Colorado publishes a turnaround of instant (online filing only). Mercury charges nothing for verification itself, so the $50 filing fee and Colorado's ongoing obligations are the real cost of getting verified as a Colorado entity.

I do not live in Colorado. Can I still use a Colorado LLC on Mercury?

Mercury does not check where you live, only that the Colorado entity is validly registered and that the details you enter match Colorado's record. The catch is not Mercury, it is the state you actually operate from: states require an out-of-state LLC to register as a foreign LLC before it transacts business there, which is a second filing and a second fee on top of Colorado's $50. Forming in Colorado while working somewhere else usually means paying both states, not one.

Do I need a Colorado sales-tax permit before my first sale through Mercury?

Probably yes. Colorado charges a 2.9% state rate, and payments taken through Mercury are not covered by marketplace-facilitator laws, so you collect and remit yourself. Register before your first taxable sale if you have physical presence in Colorado, or once you cross its remote-seller threshold of $100,000 in sales in the previous calendar year.

A Colorado LLC is generally eligible for Mercury verification — you will need to provide your Articles of Organization, EIN, beneficial-owner ID, and a valid US business address. Nothing about forming in Colorado blocks approval, and nothing about it guarantees approval either: the final call is Mercury's.

Mercury is a fintech banking platform whose deposits are held at FDIC-member partner banks (currently Choice Financial Group and Column N.A., Members FDIC), making it popular with startups and small businesses including those with non-US founders. To open a Mercury account for a Colorado LLC, you must provide the company's formation document (in Colorado, the Articles of Organization), an IRS-issued EIN confirmation, a government ID for the beneficial owner(s), and a physical US address. Mercury supports all US-state LLC types and is commonly used by foreign founders who have formed a US LLC, since it does not require founders to be US citizens or residents.

In Colorado the entity behind that check is an LLC created by filing Articles of Organization, which costs $50. Colorado publishes a turnaround of instant (online filing only). Because Colorado names a member or manager on a routine public filing, the owner name Mercury asks you to confirm is already a matter of public record.

Not legal advice: Verification requirements change, and so do Colorado's filing fees and forms. Confirm current platform rules with Mercury, and current filing rules with the Colorado filing office, before you file. Mercury's requirements were last reviewed 2026-07-21, and Colorado's figures on this page come from its own published schedule.

What Mercury requires, and how a Colorado LLC meets each

Requirement	How your Colorado LLC satisfies it
LLC formation documents	Upload the Articles of Organization Colorado returned to you, stamped and approved.
IRS EIN confirmation letter	Provide your federal EIN (free from the IRS; non-US founders without an SSN must apply via Form SS-4 by fax or phone rather than the online tool) — independent of Colorado.
Government-issued ID for owner(s)	Provide a government ID for each beneficial owner named in your Colorado filings. Colorado names a member or manager on a routine public filing, so at least one name already matches state records.
US business address	Use a US street address registered to the LLC in Colorado (your Colorado registered-agent or virtual business address), since a PO box is usually rejected.

Colorado-specific things to watch

Colorado names a member or manager on a routine public filing, so Mercury's beneficial-owner check will line up with public state records — you still upload a government ID for each owner. (Colorado's Statement of Foreign Entity Authority and periodic report place management information on the public record.)

Colorado sales tax & nexus rules for Mercury sellers

Colorado charges a 2.9% state sales-tax rate. Payments through Mercury are not covered by marketplace-facilitator laws — you collect and remit yourself. Registration is required before your first taxable sale if you have physical presence in Colorado (an in-state location, inventory, or employees), or once you cross Colorado's remote-seller economic-nexus threshold of $100,000 in sales in the previous calendar year.

Colorado has the lowest state sales tax rate at 2.9%, but its home-rule city system is uniquely complex: over 70 Colorado cities administer their own sales taxes separately. Once you have nexus, you may need to file both a state return and separate city returns. The state's Revenue Online portal handles the state portion only.

How to verify your Colorado LLC on Mercury

LLC formation documents. Upload the Articles of Organization Colorado returned to you, stamped and approved.
IRS EIN confirmation letter. Provide your federal EIN (free from the IRS; non-US founders without an SSN must apply via Form SS-4 by fax or phone rather than the online tool) — independent of Colorado.

Non-US founders with Colorado LLCs

Mercury explicitly supports non-US founders who have formed a US LLC, Colorado included. A non-US passport is accepted for identity verification. The entity must be formed and registered in the United States, and a US business address is required, which a Colorado registered agent address satisfies. No US Social Security Number is needed from the founder.
