Iowa foreign LLC registration: fee, document and filing office

To register, the outside company submits the Limited Liability Company Foreign Registration Statement (Form 635_0010) to the Iowa Secretary of State, Business Services, with a state fee of $100. Iowa also wants certificate of existence (good standing) from the state or country of formation, dated within 90 days of the filing.

After registration the company owes the biennial report ($30), due January 1 to April 1 of each odd-numbered year.

Documents to have on hand

  • Certificate of existence (good standing) from the state or country of formation, dated within 90 days of filing.
  • The legal name as recorded in the home state, and the date of formation.
  • An in-state registered agent; any provider in this report can serve.

An unregistered foreign LLC has no right to sue in Iowa courts until it registers (Iowa Code 489.902). Its contracts remain enforceable (Iowa Code 489.902(3)).
