An individual may claim a nonrefundable tax credit for making contributions or paying fees directly to a public school in this state for support of eligible activities, programs or purposes as defined by statute. The public school tax credit is claimed by the individual taxpayer on Form 322. The maximum credit allowed is $400 for married filing joint filers and $200 for single, heads of household and married filing separate filers. 

For the purpose of claiming Arizona’s tax credit for contributions made or certain fees paid to a public school, the Arizona Department of Revenue now requires taxpayers report the school’s County Code, Type Code, and District Code & Site Number (CTDS) number on Form 322, which is included with the Arizona income tax return.

The CTDS is a nine (9) digit number that the Arizona Department of Education uses to identify Arizona public and charter schools.
