We took each price from the company's own pages on November 12, 2026. On top of every row, Arizona charges a $150 registration fee, which isn't in these totals.
How the order came together
Two things count most to us, three-year cost and filings in the price, at 29% each. Renewal price, state fit and up-front totals share 42%, and Arizona came down to filings in the price.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over Arizona Registered Agent.co.
