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

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

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

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

Kansas charges $85 to file Articles of Organization, and that is the state's fee to create the LLC. Kansas publishes a turnaround of within minutes (online). Mercury charges nothing for verification itself, so the $85 filing fee and Kansas's ongoing obligations are the real cost of getting verified as a Kansas entity.

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

Mercury does not check where you live, only that the Kansas entity is validly registered and that the details you enter match Kansas'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 Kansas's $85. Forming in Kansas while working somewhere else usually means paying both states, not one.

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

Probably yes. Kansas charges a 6.5% 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 Kansas, or once you cross its remote-seller threshold of $100,000 in sales in the current or previous calendar year.

A Kansas 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 Kansas 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 Kansas LLC, you must provide the company's formation document (in Kansas, 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 Kansas the entity behind that check is an LLC created by filing Articles of Organization, which costs $85. Kansas publishes a turnaround of within minutes (online). Because Kansas 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 Kansas's filing fees and forms. Confirm current platform rules with Mercury, and current filing rules with the Kansas filing office, before you file. Mercury's requirements were last reviewed 2026-07-21, and Kansas's figures on this page come from its own published schedule.

What Mercury requires, and how a Kansas LLC meets each

Requirement	How your Kansas LLC satisfies it
LLC formation documents	Upload the Articles of Organization Kansas 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 Kansas.
Government-issued ID for owner(s)	Provide a government ID for each beneficial owner named in your Kansas filings. Kansas 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 Kansas (your Kansas registered-agent or virtual business address), since a PO box is usually rejected.

Kansas-specific things to watch

Kansas 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. (Kansas's biennial Information Report must name every member owning 5% or more of the capital.)

Kansas sales tax & nexus rules for Mercury sellers

Kansas charges a 6.5% 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 Kansas (an in-state location, inventory, or employees), or once you cross Kansas's remote-seller economic-nexus threshold of $100,000 in sales in the current or previous calendar year.

Kansas was the last state to adopt economic nexus, doing so in July 2021 with no transaction threshold — only the dollar amount matters. Kansas also applies sales tax to services more broadly than most states. The state is part of the Streamlined Sales Tax program. Kansas's combined state and local rate averages around 8.7%.

Non-US founders with Kansas LLCs

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