As any CPA would tell you, the answer to the question of whether your donation is tax-deductible depends on how you make your donation.
If you donate directly to a Ukrainian organization in Ukraine, your donation would not qualify for a tax deduction in the US.
However, if you donate to a 501(c)(3) nonprofit organization that helps Ukraine, your donation would be tax-deductible.
