Arizona Tuition Tax Credit

Helping our Students

In 1997, the state of Arizona implemented the Private School Tuition Tax Credit Law (A.R.S. Section 43-1089). The legislation allows a married couple filing jointly to make a donation to the Arizona Christian School Tuition Organization(ACSTO) up to $1,016 and receive a dollar-for-dollar credit against the taxpayer’s Arizona state income tax. A single taxpayer can give up to $508. This legislation therefore allows a taxpayer to make a sizable contribution that essentially results in no cost to him/her yet provides significant scholarships to children attending a private school. You have until April 15th to make a donation and still use it on the previous years tax return.

About ACSTOThe Arizona Christian School Tuition Organization 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. ACSTO is a tax-exempt charitable organization pursuant to federal tax law, Section 501(c)(3).

Give Parents the Choice for a Christian Education Taxpayers have long dreamed of having the ability to determine how their tax dollars are spent. The good news is now they can. The Arizona Tuition Tax Credit Act of 1997 allows taxpayers with an Arizona income tax liability to contribute up to $1,016 to a qualified School Tuition Organization. In doing so they assist children in receiving a quality, private education and receive a tax credit against their state tax obligation, and it costs them nothing. That right—it’s completely free!

Sound too good to be true? Well, it's true and here’s all you have to do to take advantage of this opportunity...

  • Complete the online or paper donation form, then simply write a check for up to $1,016 to ACSTO (Arizona Christian School Tuition Organization) by April 15 and mail your check to: ACSTO, P.O. Box 6580, Chandler, AZ 85246.
  • Or you can charge your contribution by completing the Donation Form by April 15 and mail it to: ACSTO, P.O. Box 6580, Chandler, AZ 85246.

When you prepare your Arizona State Income Tax Return, there will be a line on your tax return where you will show your contribution to ACSTO. The full amount of your contribution (up to $1,016) will then be deducted from your tax liability for the year.

If you have already paid $1,016 or more to the state through payroll deductions, the full amount of your ACSTO contribution will be refunded to you. If you owe additional money to the State, the amount you owe will be reduced by the full amount of your ACSTO contribution.

That’s it! It’s that simple—and you can rest assured knowing that your contribution is helping deserving students get a quality Christian education!
