Our top pick

1. Mainstay Filing: best for all fifty states

$149 a year, flat

Our mark 9.1 out of 10

Top grade, Mainstay Filing: the price stays $149 a year if you stay put or expand, and your first three government letters each year are scanned free.

Launching a new company? The $199 yearly package also takes care of the Washington filing and the annual report.

It runs $150 above WA Registered Agent.org across three years; the extra paperwork it handles is worth that to us.

In the price

  • An in-state street address on the public record
  • Free scan of served papers the same business day they arrive
  • Free scanning for three government mailings a year
  • Compliance reminders

Pros

  • Your first three government letters each year are scanned free
  • Works for LLCs, corporations, LPs, LLPs and nonprofits
  • $149 a year and it does not rise
  • Papers served on the company are scanned the same business day, free

Less good

  • The agent plan alone costs $50 a year more than WA Registered Agent.org
  • Without the formation package, you file the annual report yourself

The thinking behind the order

Two criteria weigh 26% each in these grades: cost to launch and stay and launch paperwork handled. Renewal behavior, state match and price transparency share 48%, and Washington turned on launch paperwork handled.

Mainstay's plan covers more ground: papers served on the company are scanned the same business day at no charge, the price is the same in all fifty states, and three government letters a year are scanned free. WA Registered Agent.org costs less, and the grades are close.

Every criterion and weight is listed on How we rank.

Washington registered agent rules, straight from Washington Secretary of State

Every LLC must name a registered agent with an in-state street address. The address has to be a physical street address in Washington. P.O. boxes and private mailboxes are not accepted. Law behind it: RCW 23.95.415.

Washington annual report: date and fee

Put the annual report on your Washington calendar every year. Count on a $70 state charge, with the deadline at last day of the entity's anniversary month. Miss it and $25 gets added. Your registered agent receives the state's notices about it.

Quick answers about Washington registered agents

Do I have to line up a registered agent before launching a Washington LLC?

Yes. Put a registered agent with a physical Washington address on the paperwork, because the state will not accept an LLC without one.

What should I budget each year for a Washington registered agent?

Expect $99 to $149 a year, and each company keeps its price at renewal.

Could I just serve as my own registered agent?

Often yes, if you meet the state's conditions. A commercial registered agent listed with the Secretary of State, a noncommercial agent (any person or business with a Washington address), or the holder of a named position in the company. The agent consents in advance.

When does the Washington annual report come due?

Put last day of the entity's anniversary month on your calendar. The state asks $70, and a late filing adds $25.

Which registered agents are graded on this page?

Mainstay Filing ($149 a year) and WA Registered Agent.org ($99 a year), top grade first.

Which Washington registered agent should a new company pick first?

Mainstay Filing, because $149 a year, still $149 at renewal, and papers served on the company are scanned the same business day at no charge.
