Iowa LLC Biennial Report — Step 6 of 8

Iowa's compliance filing is genuinely unusual: it's only ever due in odd-numbered years, on a fixed calendar window — not tied to your LLC's anniversary date at all.

IA BIENNIAL REPORT $30 ODD YEARS DUE BY APRIL 1 EVERY ODD-NUMBERED YEAR
Quick Answer

Iowa LLCs file a Biennial Report in odd-numbered years. The fee is $30 online or $45 on paper. File from January 1 and by March 31, before March 31. The first report falls in the first odd-numbered year following formation. Other tax, licensing and registration duties can still apply in even years.

What Iowa's Biennial Report Involves

Iowa's compliance filing is structured differently from almost every other state — it's tied to the calendar, not your LLC's birthday:

  • Fee: $30 online, $45 by mail — one of the lower compliance filing costs in the country.
  • Only due in odd-numbered years — 2025, 2027, 2029, and so on. There's no filing requirement at all in even years, regardless of when your LLC formed.
  • Fixed filing window: January 1 – March 31 — every LLC in Iowa files during the same window, unlike most states' anniversary-month systems.
  • Filed with: the Iowa Secretary of State through Fast Track Filing, or by mail.
  • Reminders sent to your registered agent — keeping your agent information current is your best safeguard against missing this every-other-year window.

How to File

  • File online through Fast Track Filing for instant processing and the cheapest rate, $30.
  • Review your information — confirm your LLC's name, registered agent, and mailing address are still accurate.
  • Or file by mail for $45, if you'd rather not use the online portal.
  • File any time within the Jan 1–Mar 31 window — no advantage to filing on January 1 over March 31, as long as it's submitted before the deadline.
  • Missing the window risks dissolution — unfiled LLCs can eventually be administratively dissolved by the Secretary of State.

The calendar-fixed window is the detail that trips people upMost states use an anniversary-month system, so people naturally assume Iowa works the same way. It doesn't — every LLC in the state, regardless of formation date, files during the exact same Jan 1–Mar 31 window in odd years only. Mark this window on your calendar every other year rather than tracking your formation date.

Ahmad Adil's Take: Iowa's fixed calendar window is genuinely one of the simplest reporting systems we've reviewed once you understand it — everyone files during the same three-month stretch every other year, so there's no anniversary math to track. The tradeoff is that if you form your LLC late in an odd year, you might feel like you barely missed the window and now have to wait almost two full years for the next one. That's normal; just budget for it.
