Arizona Christian School Tuition Organization, Inc. (ACSTO)
The Arizona Christian School Tuition Organization, Inc (ACSTO) was incorporated in 1998 for the sole purpose of implementing the private school tuition tax credit law passed and signed into law in 1997 as A.R.S. Section 43-1089.
Since it began in 1998, ACSTO has awarded scholarships to more than 19,000 students attending 150 Arizona Christian schools. Over 51,000 visionary Arizona taxpayers have made this possible by donating to ACSTO, and taking advantage of Arizona's unique opportunity to receive a dollar-for-dollar credit against their Arizona state income tax.
