Are donations to Massachusetts unknown nonprofits tax-deductible?
Federal deductibility is determined by IRS Publication 78 status, not state location. Donations to a Pub 78-listed unknown nonprofit in Massachusetts are tax-deductible at the federal level; Massachusetts state tax treatment may differ.
Where do unknown nonprofits in Massachusetts 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. Massachusetts state charity registration is a separate state-level requirement.
