Seattle LLC FAQ

Do I have to form my LLC at the Seattle city level?

No. LLCs are formed at the state level with the Washington Secretary of State, not at the city level. Seattle may require a separate business license to operate, but the LLC itself is a state filing.

Does Seattle have a city-specific business license?

Most Seattle businesses need a business license issued by the city or county. The exact requirements depend on industry and business activity. Contact the Seattle city clerk or use our business license lookup tool.

How much does it cost to form an LLC in Seattle?

The Washington state filing fee plus any Seattle business license fee. File.Business charges $0 service fee on top. See our Washington LLC cost breakdown.

Can I form a Seattle LLC remotely?

Yes. Washington accepts online filings. You do not need to be physically present in Seattle or Washington. File.Business handles the entire process remotely.

Should I form in Washington or in another state like Delaware?

If you operate primarily in Seattle, you should form in Washington. Forming out of state (in Delaware, for example) requires foreign qualification back in Washington, doubling fees. Delaware is best for venture-backed startups or businesses with no specific home state.
