How to start a nonprofit in Wisconsin

How to start a nonprofit in Wisconsin, step by step

1. Name your Wisconsin nonprofit

   The name must contain corporation, incorporated, company or limited, or an abbreviation. A reservation is $10 and holds 120 days (Form 1).

2. Choose your first board of directors

   Plan on at least three people who are not related to each other. Some states allow fewer on paper, but three unrelated directors is what the IRS application works best with, and what funders expect. Pick people who will actually show up.

3. File your Articles of Incorporation (Form 102, Chapter 181)

   Wisconsin's term is nonstock corporation. File Form 102 with the Department of Financial Institutions, not a Secretary of State, for $35, online through DFI's system. Expedited next-business-day service is $100.

4. Name your registered agent

   A registered agent at a registered office: a Wisconsin resident whose business office is the registered office, or an entity authorized in Wisconsin with an office there.

5. Adopt bylaws and hold your first board meeting

   Bylaws are your internal rulebook: how directors are chosen, how votes work, what officers you have. At the first meeting the board adopts them, elects officers, and approves opening a bank account. Keep minutes; they are your first governance record.

6. Get your free EIN

   It is free from the IRS; any site charging for an EIN is reselling a free thing. Apply online if your responsible party has an SSN or ITIN and your principal place of business is in the US. It takes minutes. Three limits to know: one EIN per responsible party per day, the tool is not open around the clock, and it times out after 15 minutes with nothing saved. Without an SSN or ITIN you file Form SS-4 by fax or mail instead, which takes weeks. You need the EIN for the bank account and every filing after this.

7. Apply for 501(c)(3) status with the IRS

   Two forms, two fees. The short Form 1023-EZ has a $275 user fee, but you may use it only if you clear the whole Eligibility Worksheet. That means three things. Gross receipts did not exceed $50,000 in any of the past three years. They are not projected to exceed $50,000 in any of the next three years. And total assets are $250,000 or less. Churches, schools, hospitals and a few other types cannot use it at all. Everyone else files the full Form 1023, $600. This is the step that makes donations tax-deductible. The IRS currently issues 80 percent of 1023-EZ decisions within about 22 days and 80 percent of full 1023 decisions within about 191 days. It publishes current figures on its status page. Fees read 1 September 2026.

8. Handle Wisconsin taxes

   No separate income tax application, but read the Form 4T test carefully: it is triggered by $1,000 or more of gross income from an unrelated trade or business for federal purposes, combined with doing business in Wisconsin and having to file a federal 990-T or 4720. Wisconsin supplies the nexus, not the threshold, so an organization with $1,200 of federal gross unrelated business income still files even if only a little is apportioned here. For sales tax, apply to the Department of Revenue for a Certificate of Exempt Status (CES) using Form S-103 with your IRS determination letter.

9. Register to fundraise

   Register with the DFI (again, not the AG) before soliciting: Form 296, $15. Then remember there are TWO annual obligations: the $54 registration renewal due by July 31 ($25 late fee), and a separate annual financial report due within 12 months of your fiscal year end at no fee. The DFI's own FAQ warns that people conflate them. All-volunteer organizations raising $25,000 or less with no paid employees are exempt.

10. Stay in good standing

    The corporate annual report is $25 online ($40 by paper), due during the calendar quarter of your incorporation anniversary. That is a third filing, separate from both charity filings.

Wisconsin-specific things to know

1. Two charity filings, not one

   The July 31 renewal and the fiscal-year financial report are different obligations with different deadlines. Diarize both the day you register, because the DFI says this is the mistake it sees most.

2. One agency for everything

   Incorporation, charity registration, and all renewals live at the DFI. Convenient, but it means three different DFI deadlines per year once you are running.
