Mississippi 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
Registered Agent MS.org $199 $99 $99 $397 Included
Mainstay Filing $199 $149 $149 $497 Free
Mississippi Registered Agent.co $199 $99 $99 $397 Included

Each price comes from the company's own site, read on November 12, 2026. Add Mississippi's $250 registration fee to each row; the tally above leaves it out.

How the card was marked

Formation Scorecard scores cost across three years and coverage of the price at 25% each. Renewal terms, state-by-state fit and pricing clarity account for the other 50%. In Mississippi the tie was broken by cost across three years.

Registered Agent MS.org 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.
