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

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

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

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

Wyoming charges $100 to file Articles of Organization, and that is the state's fee to create the LLC. Wyoming publishes a turnaround of instant online; up to 15 business days paper. Mercury charges nothing for verification itself, so the $100 filing fee and Wyoming's ongoing obligations are the real cost of getting verified as a Wyoming entity.

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

Mercury does not check where you live, only that the Wyoming entity is validly registered and that the details you enter match Wyoming'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 Wyoming's $100. Forming in Wyoming while working somewhere else usually means paying both states, not one.

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

Probably yes. Wyoming charges a 4% 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 Wyoming, or once you cross its remote-seller threshold of $100,000 in sales in the previous or current calendar year (no transaction-count threshold).

A Wyoming 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 Wyoming 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 Wyoming LLC, you must provide the company's formation document (in Wyoming, 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 Wyoming the entity behind that check is an LLC created by filing Articles of Organization, which costs $100. Wyoming publishes a turnaround of instant online; up to 15 business days paper. Because Wyoming 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 Wyoming's filing fees and forms. Confirm current platform rules with Mercury, and current filing rules with the Wyoming filing office, before you file. Mercury's requirements were last reviewed 2026-07-21, and Wyoming's figures on this page come from its own published schedule.

What Mercury requires, and how a Wyoming LLC meets each

Requirement	How your Wyoming LLC satisfies it
LLC formation documents	Upload the Articles of Organization Wyoming 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 Wyoming.
Government-issued ID for owner(s)	Provide a government ID for each beneficial owner, even though Wyoming names none of them publicly. Wyoming 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 Wyoming (your Wyoming registered-agent or virtual business address), since a PO box is usually rejected.

Wyoming-specific things to watch

Wyoming 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. (Neither the Articles nor the annual report requires listing members or managers; only an organizer/signer appears, so ownership stays off public filings.)
Budget for Wyoming's ongoing LLC costs before projecting your Mercury margins: Wyoming charges an annual report license tax of $60 minimum ($62 filed online), based on in-state assets; no franchise or privilege tax otherwise.
Mercury payouts flow through to your personal return, and Wyoming won't tax them under a personal income tax: Wyoming levies no personal income tax.

Wyoming sales tax & nexus rules for Mercury sellers

Wyoming charges a 4% 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 Wyoming (an in-state location, inventory, or employees), or once you cross Wyoming's remote-seller economic-nexus threshold of $100,000 in sales in the previous or current calendar year (no transaction-count threshold).

Wyoming's 4% state rate is among the lower rates nationally. Local taxes add 1-2% in most counties. Wyoming does not have a state income tax and does not tax most services or SaaS, making it a straightforward state for technology businesses. Wyoming is an SST member state. Register through Wyoming's Excise Tax Division portal. Note: Wyoming repealed its 200-transaction economic-nexus trigger (effective 2024); only the $100,000 sales threshold now applies.

Non-US founders with Wyoming LLCs

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