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

Yes. Mercury explicitly supports foreign founders with a US LLC. You need the Missouri 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 Missouri affect Mercury eligibility?

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

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

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

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

Mercury does not check where you live, only that the Missouri entity is validly registered and that the details you enter match Missouri'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 Missouri's $50. Forming in Missouri while working somewhere else usually means paying both states, not one.

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

Probably yes. Missouri charges a 4.225% 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 Missouri, or once you cross its remote-seller threshold of $100,000 in sales in the previous or current calendar year.

A Missouri 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 Missouri 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 Missouri LLC, you must provide the company's formation document (in Missouri, 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 Missouri the entity behind that check is an LLC created by filing Articles of Organization, which costs $50. Missouri publishes a turnaround of usually instant (online). Because Missouri keeps members and managers off routine public filings, Mercury has no public state record to match your owner name against, and relies entirely on the identification you upload.

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

What Mercury requires, and how a Missouri LLC meets each

Requirement	How your Missouri LLC satisfies it
LLC formation documents	Upload the Articles of Organization Missouri 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 Missouri.
Government-issued ID for owner(s)	Provide a government ID for each beneficial owner, even though Missouri names none of them publicly. Missouri publishes no member or manager, so the platform relies entirely on the ID you upload — names must match your operating agreement.
US business address	Use a US street address registered to the LLC in Missouri (your Missouri registered-agent or virtual business address), since a PO box is usually rejected.

Missouri-specific things to watch

Missouri keeps both members and managers off routine public filings, but you must still upload beneficial-owner identification directly to Mercury. State-level anonymity does not exempt you from the platform's KYC. (The Articles of Organization (Form LLC-1) require only the registered agent's and organizer(s)' names (organizers need not be members, managers, or owners) plus a member-managed/manager-managed checkbox with no names, and the Secretary of State's FAQ confirms LLCs file no annual report, so no routine public filing ever lists members or managers.)

Missouri sales tax & nexus rules for Mercury sellers

Missouri charges a 4.225% 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 Missouri (an in-state location, inventory, or employees), or once you cross Missouri's remote-seller economic-nexus threshold of $100,000 in sales in the previous or current calendar year.

Missouri was the second-to-last state to adopt economic nexus, doing so January 1, 2023. Missouri's state rate of 4.225% is among the lower statewide rates, but the combined state and local rate averages around 8.3%. Missouri has a complex local sales tax structure with over 2,000 local taxing jurisdictions. Register through MyTax Missouri.

Non-US founders with Missouri LLCs

Mercury explicitly supports non-US founders who have formed a US LLC, Missouri 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 Missouri registered agent address satisfies. No US Social Security Number is needed from the founder.
