Iowa 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
Mainstay Filing $199 $149 $149 $497 Free
IA Registered Agent.org $199 $99 $99 $397 Included
Iowa Registered Agent.co $199 $99 $99 $397 Included

Each price comes from the company's own site, read on November 12, 2026. Add Iowa's $100 registration fee to each row; the tally above leaves it out.

The case for Mainstay Filing in first

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 Iowa the tie was broken by coverage of the price.

A foreign registration touches two states, so a single provider at one price in both earned the most coverage points, ahead of IA Registered Agent.org.

Every criterion and weight appears on How we rank.

Foreign LLC registration in Iowa: fee, form and filing office

An outside company registers by sending the Limited Liability Company Foreign Registration Statement (Form 635_0010) to the Iowa Secretary of State, Business Services, with a $100 state fee. Iowa additionally requires certificate of existence (good standing) from the state or country of formation, dated no more than 90 days before filing.

Once registered, the company files the biennial report ($30), due January 1 to April 1 of each odd-numbered year.

Gather these before filing

  • Certificate of existence (good standing) from the state or country of formation, issued no earlier than 90 days before filing.
  • The company name exactly as the home state has it, plus the date it was formed.
  • An in-state registered agent; any service on this card can fill that role.
  • The state fee of $100, sent in with the filing.
  • A calendar date for the biennial report and its $30 fee.

The price of ignoring Iowa registration

An unregistered outside LLC cannot sue in Iowa courts until it registers (Iowa Code 489.902). Its contracts remain valid (Iowa Code 489.902(3)).
