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