Number one here

1. WA Registered Agent.org: best for a Washington LLC that wants to stay close to home

$199 to form, then $99 a year for the agent, plus the state fee

Our mark 9.3 out of 10

Top grade, WA Registered Agent.org: Washington formation at $199 on top of the state fee, year-one registered agent service included, then $99 a year.

You get an in-state street address for the registered office, and any papers served on the company are scanned into your online account.

The annual report is not in its published price, so that task stays on your list with Washington, due every year.

Add up three years and it lands below Mainstay Filing; cost is one of our two biggest criteria.

In the price

  • The formation filing
  • Your registered agent for year one

Pros

  • A $199 service price plus the state fee
  • Covers the first year of registered agent service
  • Then $99 a year to keep the agent

Less good

  • No annual report filing in the price
  • EIN application costs extra ($99)

Formation, agent and report

2. Mainstay Filing: best for formation, agent and annual report wrapped into one price

$199 yearly, state fee billed on top ($399 at checkout in all)

Our mark 8.8 out of 10

Next up is Mainstay Filing: the Washington formation, your registered agent and the annual report are bundled at $199 a year.

When renewal comes, Mainstay prepares and files the annual report so it is off your list. The Washington fee is $70 every year, with a last day of the entity's anniversary month deadline, and being late adds $25; Mainstay passes the fee along at cost.

WA Registered Agent.org is $200 lower across three years, which puts Mainstay Filing behind it on cost.

In the price

  • Preparation and filing of the formation document
  • Your registered agent all year
  • Annual report, prepared and filed each cycle
  • Your EIN application, done for you

Pros

  • Renews at $199 without add-ons
  • Washington's fee goes through at cost
  • A single $199 yearly price that covers the annual report
  • Your EIN application is included

Less good

  • After year one the agent portion is $100 a year above WA Registered Agent.org's

The thinking behind the order

At Launchwise Review, cost to launch and stay and launch paperwork handled each count for 26% of a grade, and renewal behavior, state match and price transparency split the remaining 48%. In Washington, cost to launch and stay made the call.

WA Registered Agent.org comes to $397 over three years, $200 under Mainstay Filing. Mainstay would file the annual report too, but an owner can handle it alone for the state fee, so the lower price took this page.

Every criterion and weight is listed on How we rank.

Launching in Washington: the state filing fee and form

Plan on $200 at the Washington Secretary of State when you file the Certificate of Formation - Limited Liability Company. Each company below adds that state fee at cost.

Next on the list: the annual report, every year, due last day of the entity's anniversary month. Set aside $70 for the state. Late filing adds $25. Every LLC must name a registered agent with an in-state street address.
