Wisconsin LLC Annual Report: Requirements, Due Dates & Filing

1. Does Wisconsin Require an LLC Annual Report?

Yes—Wisconsin generally requires LLCs to file an annual report with the Wisconsin Department of Financial Institutions (DFI) . The annual report keeps your company information up to date and helps maintain your LLC’s good standing. This applies to both domestic Wisconsin LLCs and foreign LLCs registered to do business in Wisconsin.

2. What Wisconsin LLCs Must File Each Year

Wisconsin yearly compliance is usually simple if you track the right items. Most LLCs should plan for these recurring obligations:

Annual compliance checklist

1. Wisconsin DFI Annual Report: yearly filing to keep your LLC active
2. Registered Agent renewal (if using a service): keep a valid agent and address for legal notices
3. State tax compliance (if applicable): depends on how you operate and your registrations
4. Sales tax permit filings (if applicable): if you sell taxable goods/services
5. Federal tax return (IRS): depends on SMLLC vs partnership vs S-corp election

3. Wisconsin Annual Report Due Dates (Anniversary Quarter)

Wisconsin uses an anniversary quarter system for many domestic entities, as outlined by the Wisconsin DFI annual report rules . That means your annual report is filed during the calendar quarter when your LLC’s anniversary date occurs. Foreign entities often follow a first-quarter schedule.

6. How to File Wisconsin Annual Report (Step-by-Step)

Step 1: Confirm your entity ID and anniversary quarter

Find your Wisconsin entity ID using the Wisconsin DFI entity search and confirm your domestic anniversary quarter (or foreign Q1 schedule). This determines your due date window.

Step 2: Verify your company details

Confirm your principal address, registered agent info, and any manager/member details. Annual reports are often rejected or delayed when registered agent details are outdated.

Step 3: File online (recommended) or prepare paper filing if needed

Online filing is typically the fastest option and often cheaper than paper. Paper filings can cost more due to a surcharge and take longer to process.

Step 4: Pay the fee and save proof

Pay the filing fee and save your confirmation, receipt, and a copy of the report. This helps with audits, banking, and future compliance.

7. Tips to Stay Compliant

• Set reminders based on your anniversary quarter (domestic) or Q1 (foreign)
• File online when possible and store proof of filing
• Keep Registered Agent details updated to avoid missed notices
• Maintain accurate records for banking and payment processor reviews

8. Good Standing, Dissolution & Common Problems

• Good standing impact: Annual report status can affect banking, payment platforms, and vendor onboarding
• Administrative dissolution (domestic): Entities that fail to file for years can be administratively dissolved
• Revocation/termination (foreign): Foreign entities that don’t file can risk loss of authority to do business in Wisconsin
• Common problem: Registered agent or address details are outdated, causing missed notices

9. Federal Compliance That Impacts Wisconsin LLCs

1. Federal tax return (IRS)

Your Wisconsin LLC’s federal tax filing depends on classification, according to IRS LLC tax rules : single-member LLCs often report on the owner’s return, partnerships file an informational return, and S-corp elections follow S-corp filing rules.

2. EIN (Employer Identification Number)

Many LLCs use an EIN to open bank accounts, hire employees, and work with payment processors, as issued by the IRS . Keeping your EIN-related records and IRS confirmations helps with compliance documentation.

3. BOI updates (Corporate Transparency)

If your ownership or key information changes, you may need to update federal beneficial ownership information (where applicable). This is separate from Wisconsin annual report filing but often comes up during annual reviews.

4. Other recurring federal obligations

• Payroll tax filings if the LLC has employees
• Information returns (such as 1099 forms) when required
• Keeping clean bookkeeping for audits, banking, and compliance reviews
