Before transitioning into tech, he spent years as a commercial real estate professional closing deals totaling over 100,000 square feet, giving him firsthand experience with business formation and entity structuring. He built MyStateLLC to provide the free, state-specific LLC guidance he wished existed when forming his own companies.
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 Texas LLC, you must provide the company's formation document (in Texas, the Certificate of Formation), 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 Texas the entity behind that check is an LLC created by filing a Certificate of Formation, which costs $300. Texas does not publish a processing time for LLC filings, so treat state approval as the open-ended step in your timeline rather than the Mercury review. Because Texas 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.
What Mercury requires, and how a Texas LLC meets each
| Requirement | How your Texas LLC satisfies it |
|---|---|
| LLC formation documents | Upload the Certificate of Formation Texas 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 Texas. |
| Government-issued ID for owner(s) | Provide a government ID for each beneficial owner named in your Texas filings. Texas 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 Texas (your Texas registered-agent or virtual business address), since a PO box is usually rejected. |
Texas-specific things to watch
- Texas 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. (The Certificate of Formation (Form 205) must name at least one governing person (member or manager), a public record; the annual Public Information Report also discloses management.)
- Texas issues a Certificate of Formation rather than "Articles of Organization." When Mercury asks for "formation documents," upload your Certificate of Formation.
- Budget for Texas's ongoing LLC costs before projecting your Mercury margins: Texas imposes a franchise tax; LLCs under the no-tax-due threshold ($2,650,000 total revenue for 2026-27 reports) owe $0 but must still file an annual Public Information Report.
- Mercury payouts flow through to your personal return, and Texas won't tax them under a personal income tax: Texas levies no personal income tax.
Texas sales tax & nexus rules for Mercury sellers
Texas charges a 6.25% 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 Texas (an in-state location, inventory, or employees), or once you cross Texas's remote-seller economic-nexus threshold of $500,000 in sales in the previous 12-month period.
Texas has one of the highest nexus thresholds at $500,000, giving smaller remote sellers significant breathing room. There is no transaction count. Texas's 6.25% state rate can be supplemented by up to 2% in local taxes (many cities are at the 8.25% cap). Texas broadly taxes SaaS and digital services. Register through the Texas Comptroller of Public Accounts.

How to verify your Texas LLC on Mercury
- LLC formation documents. Upload the Certificate of Formation Texas 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 Texas.
- Government-issued ID for owner(s). Provide a government ID for each beneficial owner named in your Texas filings. Texas 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 Texas (your Texas registered-agent or virtual business address), since a PO box is usually rejected.
Non-US founders with Texas LLCs
Mercury explicitly supports non-US founders who have formed a US LLC, Texas 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 Texas registered agent address satisfies. No US Social Security Number is needed from the founder.
