To close a business in Wisconsin, you have to formally dissolve the entity with the Department of Financial Institutions, close every tax account you opened at the federal and state level, pay final wages within 24 hours of separation, notify creditors under the statutory procedure, and keep the records that prove you did it. The order matters, because filing the wrong step first can cost you fees, refunds, or personal exposure.
Authorize the Dissolution Internally
Nothing gets filed with the state until the business itself decides to dissolve, and Wisconsin sets a different bar depending on entity type.
An LLC needs either an event specified in the operating agreement or the consent of all members. Not a majority. Every member. If the operating agreement is silent on dissolution, unanimous consent is still the rule.1Wisconsin State Legislature. Wisconsin Statutes 183.0701 – Events Causing Dissolution Get that consent in writing before you go further. It’s the first place disputes surface.
Corporations do it in two steps. The board passes a resolution proposing dissolution, then shareholders vote. Approval requires a majority of all votes entitled to be cast unless the articles of incorporation or bylaws set a higher threshold.2Wisconsin State Legislature. Wisconsin Statutes 180.1402 – Dissolution by Board of Directors and Shareholders Keep minutes of the board meeting and the shareholder vote. Those records protect directors and officers if anyone later challenges whether the dissolution was properly authorized.
File Articles of Dissolution With the DFI
The Wisconsin Department of Financial Institutions ends your entity’s legal existence when it accepts the dissolution filing. LLCs file Form 510. Corporations file Form 10.3Wisconsin Department of Financial Institutions. DFI Dissolve a Domestic Entity or Withdraw a Foreign Registration Both are on the DFI website and can be submitted through the online portal.
The forms ask for the entity’s exact legal name as it appears in state records, the date members or directors authorized the dissolution, and an optional delayed effective date. Any delayed date has to fall within 90 days of the DFI receiving the filing.4Department of Financial Institutions. Articles of Dissolution Instructions – Business Corporation If you don’t pick one, the dissolution takes effect at the close of business on the day the DFI processes the paperwork.
Filing Fees
- LLC dissolution: $20 online, $5 by paper mail.
- Corporation dissolution: $20 online, $35 by paper mail.
- Expedited next-business-day processing: add $25 to the applicable fee.
Check your annual report history before you file. If the entity is delinquent, the DFI will require all back annual report fees at the time of dissolution on top of the filing fee.3Wisconsin Department of Financial Institutions. DFI Dissolve a Domestic Entity or Withdraw a Foreign Registration LLC annual reports run $25 online, and missed years compound.
Once accepted, the DFI issues a stamped copy of the articles. Save a physical and digital copy. Banks, insurers, and government agencies will ask for that confirmation before closing accounts or accepting that the entity is gone.
Close Your Federal Tax Accounts
The IRS keeps expecting returns until you tell it not to. This is where a lot of closed businesses generate years of assessment notices they never see coming.
Form 966 for Corporations
If the business is a corporation, file IRS Form 966 (Corporate Dissolution or Liquidation) within 30 days of adopting the resolution to dissolve. Amend the plan later, and another Form 966 is due within 30 days of that amendment.6IRS.gov. Form 966 Corporate Dissolution or Liquidation It goes to the IRS service center where the corporation files its income tax return. LLCs taxed as partnerships or disregarded entities don’t file Form 966.
Final Payroll Filings
If you had employees, your last Form 941 has to check the final-return box on line 17 and show the last date wages were paid.7Internal Revenue Service. Instructions for Form 941 File final W-2s for all employees and the W-3 transmittal with the Social Security Administration.
Deactivating the EIN
The IRS won’t cancel an EIN, but it will deactivate the account. File every outstanding return and pay any balance owed first. Then send a letter with the EIN, the entity’s legal name and address, and the reason for closing the account to the IRS in Kansas City, MO 64108 (MS 6055) or Ogden, UT 84201 (MS 6273).8Internal Revenue Service. If You No Longer Need Your EIN
Close Your Wisconsin Tax and DWD Accounts
The Department of Revenue treats each tax account separately, and every one needs its own closing step.
Final Income or Franchise Tax Return
File a final Wisconsin return covering the period through the dissolution date and check the “Final return — corporation dissolved” box on the front. Corporations attach the plan of liquidation and a copy of federal Form 966. The final return is generally due by the 15th day of the fourth month after the dissolution date, and the tax itself is due by that same date regardless of filing extensions.9Department Of Revenue. General Information
Withholding Tax
If you had employees, closing the withholding account takes three steps. File the final withholding deposit on Form WT-6 through your last payroll date. File the annual reconciliation on Form WT-7 with all W-2s and any 1099s showing Wisconsin withholding within 30 days of closure. Then close the account through My Tax Account, by emailing DORWithholdingTax@wisconsin.gov, or by calling (608) 266-2776.10Department Of Revenue. Closing a Business
Seller’s Permit
Cancel the seller’s permit through the same Department of Revenue channels. If you posted a sales tax security deposit or bond at registration, it isn’t automatic money back. The deposit can be refunded only after 24 consecutive months of full compliance with sales and use tax obligations, and the department then has 60 days after that period ends to certify the refund.11Wisconsin State Legislature. Tax 11.925(5)(a)
Unemployment Insurance
Close the unemployment insurance account with the Wisconsin Department of Workforce Development. Email taxnet@dwd.wisconsin.gov with your UI account number and the last date of employment, submit the Account Change Information Form (UCT-6491), or use “Close My UI Account” in the online account update functions.12Department of Workforce Development. Unemployment Insurance Employer Handbook Section 2 – Tax Part 4 Do it promptly. Quarterly tax and wage reports otherwise keep accruing.
Pay Final Wages Within 24 Hours
Wisconsin’s deadline for final pay when a business closes is short and strict. When employees are separated because the employer is liquidating, ceasing operations, or relocating, all unpaid wages must be paid within 24 hours of separation.13Wisconsin State Legislature. Wisconsin Statutes 109.03 – When Wages Payable; Pay Orders Not the next payday. One day. Missing it exposes you to wage claims and penalties under Wisconsin’s wage payment laws.
Vacation is a separate calculation. Wisconsin doesn’t require employers to offer paid vacation, but if the company had a vacation policy and that policy didn’t include a written forfeiture provision, accrued unused vacation is owed to departing employees.14Department of Workforce Development. Wage Payment and Collection Law Pull the handbook before you cut final checks.
Notify Creditors
Wisconsin gives dissolving entities a statutory way to cut off creditor claims, but the protection only kicks in if you follow the procedure. There are two tracks.
Known Creditors
You may send written notice to each known creditor. The notice must describe what a claim needs to include, provide a mailing address, set a deadline at least 120 days out, and state that any claim not received by that deadline is barred.15Wisconsin State Legislature. Wisconsin Statutes 183.0704 – Known Claims Against Dissolved Limited Liability Company Corporations follow a parallel procedure.16Wisconsin State Legislature. Wisconsin Statutes 180.1406 – Known Claims Against Dissolved Corporation If you reject a claim, notify the creditor in writing that the claim is rejected and will be barred unless the creditor files suit within 90 days.
Unknown Creditors
For creditors you don’t know about, publish a notice of dissolution in a newspaper of general circulation in the county where the principal office sits. The notice must describe how to submit a claim, give a mailing address, and state that claims are barred unless the creditor files suit within two years of the publication date.17Wisconsin State Legislature. Wisconsin Statutes 183.0705 – Other Claims Against Dissolved Limited Liability Company Publication is optional, but it’s the only way to start the two-year clock. Skip it and claims can linger indefinitely.
Wind Up Operations
Dissolution doesn’t end the business instantly. A dissolved corporation continues to exist for the limited purpose of winding up: collecting debts owed to it, selling property, paying liabilities, and distributing anything left to owners.18Wisconsin State Legislature. Wisconsin Statutes 180.1405 – Effect of Dissolution The same principle governs LLCs. Debts and tax liabilities get paid before members or shareholders see any remaining assets.
During this period, cancel any local business licenses or permits issued by your city, village, or county. Municipal permits don’t automatically lapse when the state entity dissolves, and some jurisdictions will keep billing renewal fees until you formally cancel. If you registered a trade name or trademark with the DFI, file Form DFI/TRD103 to cancel it. There’s no fee.19Justia. Cancellation Of Trademark Tradename – Wisconsin
Keep the Records
Don’t shred everything the day the certificate arrives. Wisconsin requires corporations to keep certain records permanently, including minutes of shareholder and board meetings and records of actions taken without meetings.20Wisconsin State Legislature. Wisconsin Statutes 180.1601 – Corporate Records Accounting records and financial statements should stay on hand at least three years. Longer is smarter, given the two-year window for unknown creditor claims and the possibility of IRS audits.
At minimum, hold onto the articles of dissolution and stamped DFI certificate, every final tax return (state and federal), proof of creditor notifications, employee final pay records, and the internal resolution or written consent authorizing the dissolution. Those are the documents you’d need if a creditor, former employee, or tax agency comes calling after the business is gone.
If Your Entity Was Administratively Dissolved
Not every dissolution is voluntary. The DFI can administratively dissolve a business that fails to file annual reports or maintain a registered agent. To revive an administratively dissolved entity rather than leave it closed, email DFICorporations@dfi.wisconsin.gov with the entity name and ID number. The department will send reinstatement forms, which require filing every past-due annual report and paying the outstanding fees.21Wisconsin Department of Financial Institutions. DFI Administrative Dissolutions If another business took your name while you were dissolved, you may need to pick a new one.
