The fee, the form, what triggers registration in Washington, and how to file.
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.
