Appoint a Registered Agent – Must have a physical address in Wisconsin.
Adopt Bylaws & Hold Initial Meeting – Elect directors and approve governing documents.

State Filing Requirements for Non-Profits

Tax Exemption Requirements

Federal tax exemption: If you want 501(c)(3) status (or other tax-exempt status), file IRS Form 1023 or 1023-EZ. Wisconsin follows federal recognition for many purposes.
Wisconsin state income/franchise tax: Federally exempt 501(c)(3) organizations are automatically exempt from Wisconsin corporate franchise and income taxes. No additional filing required for that exemption.
Sales & use tax exemption (CES number): To make exempt purchases, nonprofits with IRS 501(c)(3) status (or qualifying religious organizations) may apply for CES number via Form S-103. Past law changes (e.g. 2021 Act 1) broadened some eligibility.
