$99 a year, flat

Our mark 9.3 out of 10

Top grade, Mississippi Registered Agent.co: a Mississippi specialist at $99 a year, supplying an in-state street address for the registered office.

  • Served documents are scanned so you can read them online

Pros

  • $99 annually with no renewal bump
  • Yearly price under Mainstay Filing's

The thinking behind the order

What made the call in Mississippi was cost to launch and stay. The grading method sets cost to launch and stay at 26%, launch paperwork handled at 26% and renewal behavior, state match and price transparency at 48% combined.

Mississippi Registered Agent.co comes to $297 over three years, $150 under Mainstay Filing. A launch that only needs an agent in Mississippi gets little from fifty-state reach, so the lower yearly price took it.

Every criterion and weight is listed on How we rank.
