Arizona 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
Arizona Registered Agent.co $199 $99 $99 $397 Included
Mainstay Filing $199 $149 $149 $497 Not stated
AZ Registered Agent.org $199 $99 $99 $397 Included

Each price comes from the company's own site, read on November 12, 2026. Add Arizona's $150 registration fee to each row; the tally above leaves it out.

Reading the order

The marking scheme gives 25% to cost across three years and 25% to coverage of the price, with renewal terms, state-by-state fit and pricing clarity sharing 50%. For Arizona, cost across three years made the difference.

Arizona Registered Agent.co tallies $397 across three years, $100 below Mainstay Filing. Both include the first agent year, so the renewal price after year one broke the tie.

Every criterion and weight appears on How we rank.
