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, Facebook 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 public guidance treats a sole proprietorship as a one-owner business structure, not as a Secretary of State entity-formation filing.
  • 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.

Saved choice: single-member LLC

Sole proprietor

Best for

Best for

Best if you want the cheapest and simplest start.

What it means

  • Washington public guidance treats a sole proprietorship as a one-owner business structure, not as a Secretary of State entity-formation filing.
  • If you use a name other than your own legal name, Washington's normal naming path is a state trade name through the Department of Revenue, not a county DBA filing.
  • A Washington sole proprietor using the owner's full legal name and having no employees and no Washington taxes or fees can be outside the normal business-license requirement, but that is not the typical retail-launch fact pattern.
  • Business income generally runs through your personal federal return, but you still handle Washington registration, Seattle, and Facebook Marketplace requirements separately.
  • 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 Certificate of Formation, a registered agent, and an initial report.
  • Washington public guidance says the annual report is due each year, and the public fee shown on April 26, 2026 is $70.
  • You keep the operating agreement internally rather than filing it with the state.
  • Federal tax treatment is generally pass-through by default for a single-member LLC unless you elect otherwise.

Why someone chooses it

  • Liability protection.
  • Cleaner setup for banking, resale paperwork, bookkeeping, and scaling.
  • Better fit for inventory, Seattle, and later hiring.

Main downside

Higher setup friction than a sole proprietorship

Up next Money and risk

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 Facebook Marketplace operator off guard in Washington.
  • Washington is not a marketplace-only no-registration state for an in-state seller.
  • Public Facebook Marketplace access materials reviewed on April 26, 2026 describe Marketplace as consumer-oriented and say businesses that list may be blocked or have listings removed.
  • No public Facebook Marketplace seller-liability-insurance threshold or universal insurance requirement was identified in the public help pages reviewed on April 26, 2026.

Do next: Review washington-specific friction.

Why this matters

Washington-specific friction

Main takeaway

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

Watch for

  • A Washington seller with physical presence still has a real Business License Application, UBI, excise-return, and Retailing B&O branch even when a marketplace facilitator is handling customer-facing retail sales tax.
  • Direct sales and facilitator-handled sales also differ on location coding and retail-sales-tax handling.
  • The reseller permit branch is more formal than many founders expect because Washington ties it to the appropriate business-license setup.
  • Seattle adds a real city-license, tax-return, home-business, and possible Establishing Use branch.
  • Washington businesses using personal property in the business also need to watch the county-assessor personal-property-listing branch, which is generally due April 30.

Facebook Marketplace-specific friction

Main takeaway

Public Facebook Marketplace access materials reviewed on April 26, 2026 describe Marketplace as consumer-oriented and say businesses that list may be blocked or have listings removed.

Watch for

  • Access depends on the main profile and can be limited by account history.
  • Shipping/checkout is not available to all users.
  • Public shipping help and public Meta merchant-policy material are partly framed around individual sellers, not a stable broad seller baseline.
  • The public onsite-checkout fee posture for individual sellers is 5% per transaction with a minimum fee of $0.40.
  • Public seller protection is limited: it is U.S.-only, tied to eligible onsite orders, capped at covered items priced at $2,000 or less, and does not protect ordinary local or off-platform payment deals.
  • Public payout help references more than one payout path, so do not build the beginner plan around one assumed payout method.
  • Listing limits can block high-volume scaling.
  • Local in-person sales are not protected the same way eligible checkout purchases are.

Insurance reality

Main takeaway

No public Facebook Marketplace seller-liability-insurance threshold or universal insurance requirement was identified in the public help pages reviewed on April 26, 2026.

Watch for

  • That is not the same as having no insurance risk.
  • If you hold inventory, meet buyers at your property, or ship physical products regularly, re-check your homeowners, renters, landlord, carrier, and commercial-liability coverage separately before scaling.

Use-permit and new-location branch

What this page helps with
