Iowa's biennial report has the simplest cadence rule in the country — and that's precisely why it gets missed. The statute (the biennial-report section of Iowa Code ch. 489, § 489.209 as historically numbered — the same requirement the current code's dissolution provisions cross-reference as § 489.212 after a recent renumbering) puts every LLC on the same clock: the report "must be delivered to the secretary of state between January 1 and April 1 of the first odd-numbered year following the calendar year in which a limited liability company was formed," and then in each following odd-numbered year. No anniversary months, no formation-year parity like Kansas — form your LLC in 2024, 2025, or 2026 and your first report lands in the same window as everyone else's: January 1 – April 1, 2027. The fee is small ($30 online via Fast Track Filing, $45 by mail or in person). The problem is the silence in between: in an even year like 2026 there is nothing to do, no notice, no invoice, no tax-season nudge — and a business habit that skips a year is a habit that's easy to lose entirely. Note the window has a front edge too: you can't knock it out early in December; filing opens January 1.
| Item | Iowa LLC |
|---|---|
| What's due | Biennial Report with the Secretary of State — name, registered agent/office, principal office (Iowa Code ch. 489 biennial-report section) |
| When | January 1 – April 1 of every odd-numbered year — statewide, same years for every LLC. Next window: Jan 1 – Apr 1, 2027 |
| First one | The first odd-numbered year following the calendar year of formation — formed any time in 2025 or 2026 → first report due in the 2027 window |
| Fee | $30 online (Fast Track Filing) / $45 by mail or in person, per the SOS filing help center |
| Late fee | None. Iowa charges nothing extra for filing late — the consequence is structural, not monetary |
| The fuse | 60 days past due = statutory grounds for administrative dissolution (§ 489.708) — i.e., roughly June 1 of a filing year |
| The process | SOS serves written notice; if the ground isn't cured within 60 days of the notice, the SOS "shall administratively dissolve the company" (§ 489.709). Dissolved, the LLC may only wind up — not carry on business |
| Reinstatement | Apply any time after dissolution (§ 489.710); once effective it relates back as if the dissolution never happened — file the application plus the delinquent report |
| Your name | Protected for 5 years after dissolution — apply later than that and § 489.710(1)(c) requires you to state a name that's still available, i.e., yours may be gone |

April 1, not April 15. Iowa's window closes two weeks before federal Tax Day. Owners who mentally file the report under "tax stuff" routinely surface on April 15 to find the window closed two weeks earlier. It's also a window, not a deadline — the state wants the report's information current as of delivery, and you simply can't file before January 1 of the filing year.
Iowa is about as forgiving as annual-report law gets: a tiny fee, no late penalty, a cure period after notice, reinstatement available indefinitely with full relation-back. Every individual rule is gentle. The system still dissolves thousands of LLCs, because the cadence is adversarial to human memory in three specific ways. First, the even-year silence: a full calendar year passes with no obligation, so the 2027 window opens against a habit that last fired in early 2025 — and a brand-new 2026 LLC has never filed one when its first window arrives. Second, the quiet fuse: with no late fee, nothing hurts on April 2 — the first consequence is a dissolution notice under § 489.709, and if the registered-agent address is stale (a common failure § 489.708 also lists as its own dissolution ground), the 60-day cure clock can burn down unseen. Third, the five-year name limit: reinstatement's relation-back generosity ends at the name — wait past five years and someone else may be operating under it. If you're already looking at a dissolved status, the triage order is in what to do if you missed your annual report — Iowa's version is unusually fixable if you move before the name clock runs.
| Where you are | What it costs |
|---|---|
| On time (Jan 1 – Apr 1, odd year) | $30 online / $45 paper |
| April 2 – ~June 1 | Nothing extra — file late, no penalty |
| ~60 days past due | Statutory dissolution grounds (§ 489.708) → SOS notice → 60-day cure window |
| Cure missed | Administratively dissolved (§ 489.709) — wind-up only |
| Reinstatement within 5 yrs | Application + delinquent report — relates back, name intact |
| After 5 yrs | Still reinstatable — but only under a name that's available (§ 489.710(1)(c)) |
Iowa is the fifth member of the biennial club alongside New York, California, Indiana, and Kansas — but it's the only one where the whole state files in the same years, which makes it both the easiest to explain and the easiest to sleep through: there's no "which year is mine?" puzzle like Kansas's parity rule, just a statewide odd-year drumbeat with a January–April window closer to Georgia's than to a single due date. Its no-late-fee silence resembles Wisconsin and Michigan — states where the first real consequence is structural rather than a dollar figure — and its 60-day-notice-then-dissolve staircase is nearly identical to Indiana's, minus Indiana's tax-clearance hurdle at reinstatement. The five-year name-protection limit mirrors Kansas's name-availability trap, though Iowa at least guarantees the name for those first five years. The 50-state table shows every state's cadence — including which of your other states quietly expect something from you in the years Iowa doesn't.
A deadline that skips every other year is the easiest kind to lose. EntityMinder pins Iowa's odd-year window, reminds you when it opens January 1 and before it closes April 1, and keeps the off-years quiet — correctly. The beta waitlist is open; planned pricing is $9/month.
