About

Arizona Christian School Tuition Organization, Inc. is a long-running Arizona STO that channels tax-credit donations into tuition scholarships for students attending participating Christian and other qualified private schools. Its focus is statewide access to faith-based private education.

ACSTO exists to make Christian education more affordable for Arizona families through tax-credit-funded tuition scholarships.

Arizona scholarship context

Arizona's STO Tax Credit Programs: Arizona operates four separate dollar-for-dollar tax credit programs that fund private school scholarships through certified School Tuition Organizations (STOs). Two programs offer individual income tax credits (Original and Switcher), and two offer corporate credits (Low-Income Corporate and Lexie's Law for disabled/displaced students). Combined, the programs have channeled approximately $2.9 billion in donations and $2.4 billion in scholarships since 1997.

Donations to Arizona SGOs can qualify for a state tax credit of up to 100% of the donation. The program is administered by Arizona Department of Revenue.

Arizona's federal scholarship tax credit status is Not Participating. Gov. Hobbs vetoed opt-in bills in 2026, and the legislature has not overridden them. The federal credit is reduced by any state credit claimed for the same contribution. The national tracker states the credit as up to $1,700 per taxpayer ($1,700 single, $3,400 married filing jointly).
