At no-out-of-pocket-cost to taxpayers, Individuals and Corporations can allocate their Arizona income tax liabilities and receive a dollar-for-dollar Tax Credit. THIS is not just a deduction, but a FULL TAX CREDIT OFFSET against Arizona state taxes that you would already owe.  You may also be able to qualify to claim your contribution as an additional deduction against your federal taxable income (consult your tax advisor). STO4KIDZ in-turn awards a minimum ninety percent of every contribution in scholarships to qualified K-12 students attending qualified private schools in Arizona on monthly bases.
