Step-by-step foreign qualification requirements, fees, and filing instructions for New York LLCs expanding into Washington.
Before filing, verify that your LLC name (or a distinguishable variation) is available in Washington. If your exact name is already taken, you may need to register under a fictitious or assumed name.
Search Washington business names ↗Washington requires a Certificate of Status from New York to prove your LLC is in good standing. The fee is $25. When Washington is the destination for a foreign qualification, the home-state certificate must have been issued no more than 60 days before the registration statement is submitted.
Order from New York ↗Submit your application along with the Certificate of Status and the $200 filing fee. See the processing time under Ongoing compliance below. Expedited processing is available, priced under Ongoing compliance below. Online filing is available.
Washington filing portal ↗You must designate a registered agent with a physical address in Washington to accept legal documents on behalf of your LLC. This is required as part of the foreign qualification application.

It says only that documents are processed in the order received. The only turnaround it publishes is purchased: $100 for expedited service, generally processed within three working days, available online or by post if the envelope is labelled EXPEDITE, and $150 for same day service
Both sit on top of the filing fee. To buy the $100 by post you must enclose the extra $100 and write EXPEDITE on the outside of the envelope; online it is added at checkout. Washington does not refund payments

Washington carves 13 activities out by statute. On their own, none of them requires a foreign LLC to register.
Under RCW 23.95.520, all 13 items. MOST IMPORTANT: item (1)(m), "Employing a remote worker who resides in Washington state," was added by 2026 c 80 s 7 and is an express statutory safe harbor for remote employment. It is unqualified on its face, with no headcount cap and no role exclusion. Washington appears to be the first state to enact one. The amendment is current on the legislature's site but has not propagated to most secondary publishers, so many other sources still show the pre-2026 12-item list. Subsection (4) confirms the carve-out is registration-only and does not shelter the company from B&O tax, payroll tax, or service of process.
A virtual mailbox gives your LLC a separate address in Washington for business mail. Confirm whether the state accepts it for the specific filing field. For banking, ask your bank before buying; it may require your actual operating address.
