He built MyStateLLC to provide the free, state-specific LLC guidance he wished existed when forming his own companies.
Amazon's Seller Identity Verification (KYC) checks that your business is a real, registered entity and that you are an authorized representative. For a Washington LLC, Amazon verifies the legal entity name exactly as it appears on your Certificate of Formation, a beneficial owner's government ID, a valid business address, and a bank account that can receive disbursements. Forming the LLC correctly in Washington is what lets you clear each check.
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 Amazon Seller Central 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 Amazon Seller Central requires, and how a Washington LLC meets each
| Requirement | How your Washington LLC satisfies it |
|---|---|
| Legal business name match | Use the exact LLC name as Washington recorded it on your Certificate of Formation; it must match your bank account holder name. |
| Business registration document | Upload the Certificate of Formation Washington returned to you, stamped and approved. |
| Beneficial owner identity | 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. |
| Valid 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. |
| Disbursement bank account | Link a US business bank account opened with your EIN and your Washington Certificate of Formation. |
| Tax interview (W-9/W-8) | 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. |
Washington-specific things to watch
- Washington names a member or manager on a routine public filing, so Amazon Seller Central'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 Amazon Seller Central asks for "formation documents," upload your Certificate of Formation.
- Budget for Washington's ongoing LLC costs before projecting your Amazon Seller Central margins: Washington imposes the Business & Occupation (B&O) tax on gross receipts.
Washington sales tax & nexus rules for Amazon Seller Central sellers
Washington charges a 6.5% state sales-tax rate, and like every state with a sales tax it has a marketplace-facilitator law — Amazon Seller Central 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
Non-US owners of a Washington LLC complete Amazon's same onboarding flow, but the correct tax-interview form depends on the LLC's tax classification. If you are a non-US individual and your Washington LLC is a single-member disregarded entity (no corporate-tax election), the IRS looks through the LLC to you as the owner, so you complete a W-8BEN rather than a W-9. If the owner is a foreign entity, the Washington LLC's owner files a W-8BEN-E instead. If the Washington LLC has elected to be taxed as a corporation or partnership, it submits a W-9 using its own EIN. The wrong form can trigger an account hold, so confirm your Washington LLC's classification with a US tax advisor before you start the interview. Identity verification itself accepts a non-US government photo ID.
