Frequently asked questions about environment nonprofits in Texas

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

How many environment nonprofits operate in Texas?
Every IRS-registered environment nonprofit in Texas 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 environment nonprofit in Texas?

How do I vet a environment nonprofit in Texas 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 Texas 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 Texas are tax-deductible at the federal level; Texas state tax treatment may differ.
Where do environment nonprofits in Texas 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. Texas state charity registration is a separate state-level requirement.
