How to Choose Conservative Charities
Clarify your goal before selecting an organization. If you want to fund research and policy advocacy, Heritage Foundation is the most established option. If you want to fund litigation with clear outcomes, Institute for Justice or ADF depending on issue area. If you want to invest in education and ideas for younger audiences, FEE is efficient and well-run. Always check Charity Navigator or Candid ratings before donating, and review the most recent Form 990 to understand how funds are allocated. A high program-expense ratio, typically above 75%, indicates an organization that directs most donations to its stated mission.

Frequently asked questions
How do I verify that a conservative charity is legitimate and well-run?+
The most reliable method is checking the organization's rating on Charity Navigator, GuideStar (now Candid), or the Better Business Bureau Wise Giving Alliance. These platforms review financial transparency, board governance, and program effectiveness. IRS Form 990 filings, which are public for all 501(c)(3) organizations, show how much goes to programs versus administration. A reputable charity typically puts 75% or more of spending toward its stated mission.
Are donations to conservative nonprofits tax-deductible?+
Donations to 501(c)(3) organizations are generally tax-deductible in the United States, regardless of the organization's political orientation. However, donations to 501(c)(4) advocacy organizations are typically not deductible. Check each organization's status before donating if tax deductibility matters to your decision. A tax advisor can confirm what qualifies given your specific situation.
