Are donations to Wisconsin animal-related nonprofits tax-deductible?
Federal deductibility is determined by IRS Publication 78 status, not state location. Donations to a Pub 78-listed animal-related nonprofit in Wisconsin are tax-deductible at the federal level; Wisconsin state tax treatment may differ.
Where do animal-related nonprofits in Wisconsin file their Form 990?
