Washington foreign registration service cost in 2026: first year, renewal and the three-year tally

Service First year Second year Third year Three-year tally Agent paid in year one
Mainstay Filing $199 $149 $149 $497 Free
WA Registered Agent.org $199 $99 $99 $397 Included

Each price comes from the company's own site, read on November 12, 2026. Add Washington's $180 registration fee to each row; the tally above leaves it out.

What broke the tie

Coverage of the price decided the Washington card. The method puts 25% on cost across three years and 25% on coverage of the price, then shares 50% among renewal terms, state-by-state fit and pricing clarity.

A foreign registration touches two states, so a single provider at one price in both earned the most coverage points, ahead of WA Registered Agent.org.

Every criterion and weight appears on How we rank.
