Registering a foreign LLC in Iowa: fee, form and who gets it

To register, the company files the Limited Liability Company Foreign Registration Statement (Form 635_0010) with the Iowa Secretary of State, Business Services and pays the state's $100. Iowa also wants certificate of existence (good standing) from the state or country of formation, issued within 90 days of the filing.

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

What to pull together first

  • Certificate of existence (good standing) from the state or country of formation, issued in the 90 days before you file.
  • The company name exactly as the home state spells it, and when it was formed.
  • An in-state registered agent; any service the desk picked can fill that seat.
  • $100 for the state, paid when you file.
  • A date on your calendar for the biennial report and its $30 fee.

What it costs to ignore Iowa registration

Until it registers, an outside LLC has no right to sue in Iowa courts (Iowa Code 489.902). The contracts it signs stay good (Iowa Code 489.902(3)).
