Frequently asked questions about health nonprofits in Wisconsin

Answers compiled from the IRS Form 990, BMF, Pub 78, and Auto-Revocation List.

How many health nonprofits operate in Wisconsin?
Every IRS-registered health nonprofit in Wisconsin appears in the Givalgo Discover index. The top 50 by reported revenue are listed on this page; the full set is searchable on discover.givalgo.ai.
What's the largest health nonprofit in Wisconsin?
The single largest health nonprofit in Wisconsin by reported total revenue is shown at the top of the list on this page, sourced from each organisation's most recent IRS Form 990 filing.
How do I vet a health nonprofit in Wisconsin before donating?
Use Givalgo Discover's free profile for the organisation: it cross-references the IRS Auto-Revocation List, IRS Publication 78, and the IRS Business Master File, and exposes the latest Form 990 financials and governance signals on a single page.
Are donations to Wisconsin health nonprofits tax-deductible?
Federal deductibility is determined by IRS Publication 78 status, not state location. Donations to a Pub 78-listed health nonprofit in Wisconsin are tax-deductible at the federal level; Wisconsin state tax treatment may differ.
Where do health nonprofits in Wisconsin file their Form 990?
All US tax-exempt organisations file Form 990 with the IRS at the federal level — there is no state-specific filing for the federal exemption itself. Wisconsin state charity registration is a separate state-level requirement.
