1. Mainstay Filing: best for formation, agent and annual report for one price

$199 each year plus the state fee ($399 due at checkout)

9.2Editorial score
out of 10

Mainstay Filing wins here: $199 a year pays for the formation filing, a full year as your registered agent and the annual report, renewing at $199.

Mainstay files the annual report for you as part of the renewal. Washington charges $70 every year, due last day of the entity's anniversary month, and a late filing adds $25; the state's fee is passed through at cost.

The three-year bill is $200 higher than WA Registered Agent.org's, and the wider coverage is worth that to us.

8.9Editorial score
out of 10

Second place goes to WA Registered Agent.org: Washington formation at $199 over the state's fee, year-one registered agent service included and $99 a year to keep the agent.

The plan gives the company an in-state street address as its registered office, and papers served on the company are scanned to your online account.

The annual report filing is not in its published prices, so you file it with Washington yourself every year.
