How registered agents work in Washington
Washington adopted a uniform registered agent framework in chapter 23.95 RCW. Under RCW 23.95.415, your company’s filing names one of the following:
- A commercial registered agent. These are businesses or individuals that have filed a listing statement with the Secretary of State saying they are in the business of serving as registered agents in Washington, with a Washington place of business. You only give the agent’s name; its address is already on file.
- A noncommercial registered agent. Any other individual or entity serving as your agent, listed with name and address.
- An office or position. Washington also lets a company name a title, such as “managing member,” so that whoever holds that position receives process at the stated address.
Wherever the law requires an address, RCW 23.95.410 requires a street address in Washington, plus a Washington mailing address if it is different.
Washington’s consent rule
A registered agent cannot be appointed without first consenting in a record, and that consent goes to the Secretary of State with the filing that makes the appointment. If someone is named without agreeing, that person can file a notarized statement saying so, and the Secretary of State removes the name immediately, which leaves your company without an agent.
The practical lesson: always line up and document your agent’s consent before you file anything.
What does a Washington registered agent do?
The agent is the official point of delivery for service of process, notices and demands aimed at your company. If your LLC is sued, the summons is delivered to the agent’s Washington address; if a state agency needs to send a formal notice, it goes there too.
That makes reliability the main thing to look for. A good agent has a staffed Washington office during business hours, records each delivery, and gets documents to the owners right away, ideally by scanning them to an online account. Because many legal deadlines start running at delivery, a slow or unreachable agent can cost a company the chance to respond to a lawsuit. When comparing services, also check whether the renewal price matches the first-year price.
Can you be your own registered agent in Washington?
Yes. An owner or manager with a Washington street address can serve as a noncommercial registered agent, or the company can name a position the owner holds. Either way, process is delivered to that Washington address.
The drawbacks are the usual ones:
- The agent’s name and address are part of the Secretary of State’s public records
- Someone has to be there to receive service of process and official notices
- Owners in Oregon, Idaho or further away need a Washington agent instead
- Moving your office means filing a change, though in Washington that change is free
How much does it cost to change a registered agent in Washington?
Nothing. WAC 434-112-085 lists “designation or statement of change of registered agent” at no fee for business entities as of October 2026. A registered agent’s resignation is also free, as is an agent’s resignation when it was appointed without consent.
Expedited handling has its own fees under the Secretary of State’s rules, but a standard change costs $0. The meaningful costs for a Washington LLC are elsewhere: $180 to form and $70 for each annual report. Mainstay’s Washington LLC cost guide covers the totals.
How to change your registered agent in Washington
Under RCW 23.95.430, the company files a statement of change. Members, managers or shareholders do not need to approve it.
- Choose the new agent and get its consent in writing. The consent must be on the statement or attached to it.
- Sign in to CCFS and select your business.
- File a statement of change of registered agent, entering a commercial agent’s name, or a noncommercial agent’s name and Washington street address.
- Submit. There is no state fee for a standard filing.
- Check the business record to confirm the new agent appears.
What happens if your agent resigns or can’t be found?
Agents can resign at no cost, and when they do, your company needs a new one. If no agent can be served, a plaintiff can serve process through the Secretary of State, which charges $50 per entity per address under WAC 434-112-085. Notice may then reach you late or not at all.
Missing the annual report creates a separate problem: a $25 delinquent fee and, if it continues, administrative dissolution, with reinstatement costing $140 plus all delinquent annual report fees.

What is a commercial registered agent in Washington?

Companies that appoint one list only its name.
