Is my Arizona tax credit contribution also eligible for a federal income tax deduction?
Donations made after August 27, 2018 are not eligible for an Arizona state credit and a federal deduction per recent IRS determination. Arizona donors are still eligible to receive a dollar-for-dollar state income tax credit. Donations made on or prior to August 27, 2018 are potentially eligible for a federal tax deduction and state income tax credit. Please consult your tax advisor to better understand your specific situation.
