Educational guide, not legal or tax advice.

The Certificate of Formation is the state filing that creates a domestic Washington LLC. Until this filing is accepted, the LLC is not formed as a state entity.

What the filing usually covers

Field	What to prepare
LLC legal name	Search availability before filing
Registered agent	Must meet Washington requirements
Principal or mailing address	Use consistent business records
Organizer	Person preparing/submitting the filing
Management details	Member-managed or manager-managed if requested
Filing fee	$200 online / $180 paper

Filing route

Use Washington Corporations and Charities Filing System if you want the cleanest workflow. Paper filing may be available, but online filing usually reduces mailing delay and helps catch missing fields.

Double-check before payment

Before paying the $200 online / $180 paper filing fee, review the legal name, LLC designator, registered-agent consent, mailing address, organizer details, and management selection. A typo in the Washington Certificate of Formation record can create bank, EIN, tax-registration, or amendment problems later.

What approval does and does not prove

An accepted Certificate of Formation means the state created the LLC record. It does not prove the business has every license, tax account, trademark right, seller permit, employer account, insurance policy, or local approval it may need. Treat approval as the entity-formation step, then finish the operating and compliance setup before the business starts taking on customers, employees, leases, or regulated work.

After approval

Approval is not the end of setup. Save the approved filing, finish the operating agreement, apply for an EIN if needed, open a business bank account, register for taxes or licenses if required, and calendar the annual report.

Filing FAQ

Is the operating agreement filed with the Certificate of Formation?

Usually no. The operating agreement is an internal company document.

Does the $200 online / $180 paper filing fee include tax permits?

No. Formation, tax registration, licenses, EIN, and registered-agent service are separate items.
