Step-by-step foreign qualification requirements, fees, and filing instructions for Delaware LLCs expanding into Washington.
Registering in Washington is one answer. The other is to move the LLC to Washington and stop paying Delaware, a filing called domestication, which Washington itself calls a conversion. The LLC keeps its EIN, bank accounts and contracts; only its state of formation changes.
A filing service, not a registered agent. It does not replace the agent Washington requires.
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 Good Standing (Short Form) from Delaware to prove your LLC is in good standing. The fee is $50. Available to order online.

Order from Delaware ↗Submit your application along with the Certificate of Good Standing (Short Form) 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.

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.
