No.1

Best here

1. WA Registered Agent.org: best for a Washington LLC that expects to stay put

Score9.6out of 10
$199 for formation, then $99 a year for the agent, plus the state fee

Top grade, WA Registered Agent.org: $199 plus the Washington filing fee, year-one registered agent service included, then $99 a year.

The plan seats the company at an in-state street address and posts scans of papers served there to your online account.

The annual report is outside its published prices, so you submit it to Washington yourself every year.

Three years of service cost less here than with Mainstay Filing, and cost counts heavily in the grade.

What you get

  • Washington formation filed for you
  • The first year as your registered agent

Good

  • Then $99 per year for the agent
  • First-year registered agent service is part of the price

Report filing included

2. Mainstay Filing: best for formation, agent and annual report on one invoice

Score9.4out of 10
$199 a year plus the state fee, $399 due at checkout

Second grade, Mainstay Filing: $199 a year buys the Washington formation, a year as your registered agent and the annual report filing, then renews at $199.

The renewal covers the annual report, which Mainstay files for you. Washington collects $70 every year, with a deadline of last day of the entity's anniversary month, and a late filing adds $25; Mainstay passes the state's fee through at cost.

WA Registered Agent.org is $200 cheaper across three years, and that difference lowers Mainstay Filing's cost grade.

What you get

  • Formation paperwork handled and filed
  • A registered agent for the whole year
  • The annual report prepared and filed
  • The EIN application

Good

  • A single $199 yearly price, including the annual report
  • Washington's state fee is passed through at cost
  • Includes the EIN application
  • Renewal is $199 with no add-ons

Weak spots

  • Its agent renews at $100 a year more than WA Registered Agent.org's

The basis for the order

Biz Formation Report grades three-year bill and what the money buys at 32% each, leaving 36% for renewal handling, local rules match and pricing openness. In Washington, three-year bill settled the order.

Total outlay with WA Registered Agent.org over three years: $397, $200 less than Mainstay Filing. Mainstay would add the annual report filing, but owners can file it alone for the state fee, so the lower price decided the grade.
