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.
Walmart Marketplace requires sellers to pass a multi-step business verification process before listing products. For a Washington LLC, this includes providing an EIN (US Business Tax ID), completing a W-9 tax classification, submitting your Washington business registration documentation (the Certificate of Formation), and verifying the identity of the legal representative. Walmart cross-checks all information with federal and state records, and the process typically takes a few minutes to a few business days. Payouts are disbursed via a connected payment processor. Payoneer is the default.
In Washington the entity behind that check is an LLC created by filing a Certificate of Formation, which costs $200. Washington publishes a turnaround of within 15 business days (paper). Because Washington names a member or manager on a routine public filing, the owner name Walmart Marketplace asks you to confirm is already a matter of public record.
Washington has 37,241 solo retail trade businesses with no employees, averaging $55,390 in annual receipts (U.S. Census Bureau, Nonemployer Statistics (NES), 2023).
What Walmart Marketplace requires, and how a Washington LLC meets each
| Requirement | How your Washington LLC satisfies it |
|---|---|
| US Business Tax ID (EIN) | 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 Washington. |
| W-9 tax classification | Complete the tax interview. A Washington LLC owned by US persons typically submits a W-9 using its EIN; non-US owners of a disregarded-entity Washington LLC generally use a W-8 form instead. |
| Business name and address match IRS records | Use the exact LLC name as Washington recorded it on your Certificate of Formation; it must match your bank account holder name. |
| State business registration documentation | Upload the Certificate of Formation Washington returned to you, stamped and approved. |
| Legal representative personal ID | Provide a government ID for each beneficial owner named in your Washington filings. Washington names a member or manager on a routine public filing, so at least one name already matches state records. |
| Verified US business address | Use a US street address registered to the LLC in Washington (your Washington registered-agent or virtual business address), since a PO box is usually rejected. |
| Payment processor account for disbursements | Link a US business bank account opened with your EIN and your Washington Certificate of Formation. |
Washington-specific things to watch
- Washington names a member or manager on a routine public filing, so Walmart Marketplace's beneficial-owner check will line up with public state records — you still upload a government ID for each owner. (Washington's report records the LLC's governors (members/managers) on the public record.)
- Washington issues a Certificate of Formation rather than "Articles of Organization." When Walmart Marketplace asks for "formation documents," upload your Certificate of Formation.
- Budget for Washington's ongoing LLC costs before projecting your Walmart Marketplace margins: Washington imposes the Business & Occupation (B&O) tax on gross receipts.
Washington sales tax & nexus rules for Walmart Marketplace sellers
Washington charges a 6.5% state sales-tax rate, and like every state with a sales tax it has a marketplace-facilitator law — Walmart Marketplace collects and remits Washington sales tax on your marketplace orders for you. You still need your own Washington registration if you also sell off-marketplace (your own site, invoices) and either have physical presence in Washington — an in-state location, inventory, or employees — or cross the state's remote-seller economic-nexus threshold of $100,000 in sales in the previous or current calendar year.
Washington has no transaction count threshold. Washington's combined state and local rates range from 7.5% to 10.4% depending on location — Seattle is at 10.25%. Washington broadly taxes digital products, streaming services, and SaaS. The state also has a Business & Occupation (B&O) tax on gross receipts which is separate from sales tax. Register through the Washington Department of Revenue.

Non-US founders with Washington LLCs
Walmart Marketplace eligibility for non-US businesses varies by country of incorporation. For a Washington LLC owned by non-US founders, the entity must be validly formed with a US address and an EIN, which the Certificate of Formation plus an EIN letter establishes. The legal representative completing verification must provide a valid government ID. Check Walmart's current seller application for the list of supported international seller countries, as eligibility expands periodically.
