Part 1 of 3

Start here before you spend heavily

A short orientation for the guided journey before the detailed launch steps begin.

Short answer

Use this first part only to get oriented. The detailed state, platform, local, and packet steps will follow in order.
  • First decide whether you are launching as a sole proprietor or a single-member LLC.
  • Then work through the Washington registrations, Walmart Marketplace setup, local checks, and packet review in order.

Do next: Do not spend money yet.

Part 2 of 3

Compare sole proprietor and LLC

The side-by-side setup comparison.

Short answer

Read both setup paths before you decide which one you want the rest of the launch flow to follow.
  • Best if you want the cheapest and simplest start.
  • Washington does not require a Washington Secretary of State formation filing just to exist as a sole proprietor.
  • Faster launch.

Do next: Review sole proprietor.

Save the path you want to optimize around

The unchosen setup stays visible for comparison, but the chosen one gets visual priority so the reading path feels more intentional.

What it means

  • Washington does not require a Washington Secretary of State formation filing just to exist as a sole proprietor.
  • Washington Department of Revenue public guidance says a sole proprietor with no employees and no Washington taxes or fees is not required to have a business license if using the owner's full legal name. That exception is usually too narrow for a normal Washington-based Walmart Marketplace merchandise seller.
  • If you use a name other than your legal name, Washington's normal naming path is a state trade name through the Department of Revenue, not a county DBA.
  • Business income generally runs through your personal tax return.
  • You usually do not get a liability shield.

Why someone chooses it

  • Faster launch.
  • Lower up-front filing cost.
  • Fewer entity maintenance steps.

Main downside

Personal liability

single-member LLC

Best for

Best for

Best if you want a more durable setup for a real business.

What it means

  • Washington LLC formation uses the Washington Secretary of State Certificate of Formation.
  • Washington public filing guidance says the initial report is free if filed with the formation and otherwise costs $10 if filed separately within 120 days.
  • Washington Secretary of State public guidance says the annual report fee is $70, due on the last day of the month in which the business was originally formed or registered.
  • Federal tax treatment is usually pass-through by default for a single-member LLC unless you elect otherwise.

Why someone chooses it

  • Liability protection.
  • Cleaner setup for banking, suppliers, bookkeeping, and scaling.
  • Better fit for inventory, employees, trademarks, and platform verification.

Main downside

Higher setup friction and recurring maintenance than a sole proprietorship

Part 3 of 3

See the money and risk realities before you spend

The upfront friction and risk notes that shape the launch decision.

Short answer

These are the friction points most likely to catch a new Walmart Marketplace operator off guard in Washington.
  • Washington is not a no-registration state for an in-state marketplace seller.
  • Application is not just a signup form. Public Walmart pages still expect business tax documentation, business address proof, product-ID readiness, returns capability, and marketplace or eCommerce history.
  • Walmart has a public conditional liability-insurance policy, not a universal day-one insurance requirement for every new seller.

Do next: Review washington-specific friction.

Why this matters

Washington-specific friction

Main takeaway

Washington is not a no-registration state for an in-state marketplace seller.

Watch for

  • Marketplace-facilitator collection does not eliminate the Washington Business License Application, UBI, excise-return, or B&O branch.
  • The reseller-permit path is separate from customer-facing marketplace tax collection.
  • Washington LLC upkeep is not terrible, but you still have the initial report and recurring annual-report branch.
  • Seattle adds a real city license, city return, home-business, and use-permit layer.

Walmart Marketplace-specific friction

Main takeaway

Application is not just a signup form. Public Walmart pages still expect business tax documentation, business address proof, product-ID readiness, returns capability, and marketplace or eCommerce history.

Watch for

  • Business verification, payout setup, payment holds, and fulfillment settings all have to align with real-world records.
  • Category-specific referral fees, return-center rules, policy enforcement, and seller-performance standards can all affect launch success.
  • WFS, GTIN exemption, Brand Portal, liability insurance, and Resold each have their own separate branches instead of one universal setup.
  • Public pages do not guarantee approval for your exact category, business history, or inventory type in advance.

Insurance reality

Main takeaway

Walmart has a public conditional liability-insurance policy, not a universal day-one insurance requirement for every new seller.

Watch for

  • As of the public policy reviewed on April 26, 2026, Walmart Marketplace says a seller must submit a Certificate of Insurance (COI) with general liability and product liability insurance if the seller exceeds $100,000 in GMV in any 12-month period or if Walmart notifies the seller directly.
  • The public policy says the required limits are $1,000,000 per occurrence and $2,000,000 aggregate, and Walmart Inc., its subsidiaries and its affiliates must be listed as additional insured.
  • Even below that threshold, Walmart encourages sellers to maintain insurance.
  • Keep Wallet FDIC coverage and seller-shipping protections separate from seller liability insurance. They are not the same thing.

What this page helps with

Platform insurance threshold or requirement

What this page helps with

Tax seattle.gov
Use-permit and new-location branch

What this page helps with

Public pages say all land uses are established by permit and that opening a new business or changing the use of a property can require permit review even when no major remodel is planned.
