Wisconsin keys the LLC annual report to a unit no other state uses: the calendar quarter. Under Wis. Stat. § 183.0212, a domestic LLC files "during the calendar year quarter in which the anniversary date of the articles' effective date occurs" — in practice, by March 31, June 30, September 30, or December 31, whichever quarter holds your formation anniversary. That's looser than an exact-date state, and the looseness is the trap: it's not a fixed date you can memorize, and it's not your anniversary day either, so both of the usual mental models produce a wrong answer. Two more wrinkles compound it. The filing goes to the Department of Financial Institutions (DFI) — Wisconsin's Secretary of State doesn't handle business filings, so searching "Wisconsin Secretary of State annual report" leads you somewhere that can't help you. And Wisconsin charges no late fee whatsoever — miss the deadline and nothing happens, visibly, for a long time. The first real consequence arrives under § 183.0708: once the report is a year overdue, the state holds statutory grounds to administratively dissolve your LLC — and the day it does, your exclusive right to your business name ends with it.
| Item | Wisconsin LLC |
|---|---|
| What's due | Annual report with the Wisconsin Department of Financial Institutions (DFI) — not a Secretary of State |
| Deadline | During the calendar quarter containing your formation anniversary — so the practical deadline is that quarter's last day: Mar 31 / Jun 30 / Sep 30 / Dec 31 (Wis. Stat. § 183.0212). First report is due the year after the year your articles became effective |
| Foreign LLCs | File every year during the first calendar quarter (by March 31), regardless of registration anniversary (§ 183.0212) |
| Fee | $25 online for a domestic LLC via the DFI's portal; $40 by mail per the DFI's paper-form instructions (a $15 paper surcharge). Foreign LLCs pay more — roughly $80 [reported by multiple filing services; confirm current amounts on the DFI's site before filing] |
| Late fee | None. Wisconsin publishes no monetary penalty for a late annual report — the consequence is structural, not financial (below) |
| A year overdue | Statutory grounds for administrative dissolution (§ 183.0708(1)(b)) |
| On dissolution | Your LLC may only wind up or apply for reinstatement — and the exclusive right to your name terminates on the dissolution date (§ 183.0708(4m)) |
| Getting back | Reinstatement application under § 183.0709 — statement that each ground was cured or never existed, a name that still complies, and all fees and penalties paid; the application fee is $100 [reported by filing services; confirm with the DFI] |
| Where | Online at the DFI's business services portal |
Which quarter is yours? Take the effective date of your articles of organization — not the day you started doing business — and find its calendar quarter. Formed February 10? Your report is due by March 31 every year. Formed July 1? September 30. An LLC formed in the last week of a quarter gets its shortest runway: formed March 28, the window still closes March 31.
States like Illinois hit a late LLC with a $100 penalty — painful, but loud. Wisconsin's design is the opposite: nothing is charged, nothing is demanded, and an owner who missed a quarter-end two years ago may have no idea anything is wrong. The machinery underneath is running anyway. Under § 183.0708(1), the DFI may commence dissolution proceedings once an LLC "does not have on file with the department its annual report within one year after it is due" — the same section reaches an LLC that's been without a registered agent for a year, or that sat on unpaid DFI fees for a year. From there the process is notice-based: the DFI gives written notice to your registered agent, and within 60 days the LLC must either correct each ground or demonstrate it doesn't exist (§ 183.0708(3)). Fail that, and the department may dissolve the company. If the notice bounces, the statute doesn't stop — it redirects: first to your principal office, and if that's undeliverable too, notice by posting on the department's website (§ 183.0708(3m)). An LLC with a stale agent and a stale address can therefore complete the entire journey from "missed a $25 filing" to "dissolved" without a human ever successfully being told.
Buried in the dissolution section is a line with real commercial teeth: "A limited liability company's right to the exclusive use of its name terminates on the date of the administrative dissolution" (§ 183.0708(4m)). Not after a grace period, not after a year — on the date. From that day, the name you've built a brand on is available for someone else to register, and reinstatement under § 183.0709 requires a statement that your name still satisfies Wisconsin's name-availability rules — which it may no longer do if someone took it while you were dissolved. Colorado is notorious for releasing a delinquent entity's name after 400 days; Wisconsin's version is faster and quieter. Reinstatement itself is otherwise reasonably forgiving — cure the grounds, pay everything owed plus the application fee, and reinstatement relates back as if the dissolution never happened — but only if the name is still yours to reclaim.
| Where you are | What it costs |
|---|---|
| On time (by your anniversary quarter's last day) | $25 online / $40 by mail |
| Late, under a year | $0 in penalties — but you're out of good standing, which surfaces at the worst times (loans, closings, contract diligence) |
| A year overdue | Dissolution grounds armed; DFI notice starts a 60-day cure clock |
| Dissolved | Winding-up only; name protection gone the same day |
| Reinstating | $100 application [reported — confirm with DFI] + every fee and penalty owed, with a name that must still be available |
Wisconsin's quarter cadence has no true peer, but its neighbors make a useful contrast set. Illinois wants $75 before the first day of your anniversary month with a $100 penalty at 60 days late. Michigan bills every LLC $25 on the same fixed date, February 15. Minnesota is free but unforgiving of the December 31 date. And Indiana files only every other year. An owner with entities in two or three of these states is juggling a fixed date, an anniversary month, a biennial cycle, and Wisconsin's quarter — four different rhythms, one calendar. Already past a deadline somewhere? Start with what to do if you missed your annual report.
A deadline with no late fee is the easiest one to forget — Wisconsin's first warning can be a dissolution notice.
