Two credits against Arizona State income tax exist for contributions to private school tuition organizations.
A taxpayer may claim a credit for $528/$1,070 (single/married) for the standard private school tuition organization credit.
Beginning in 2012, taxpayers have been allowed an additional amount, which is restricted to students who switch from public to private schools. This credit can only be claimed when the first credit has been claimed and is maxed out. The additional amounts for 2014 are $525/$1,050 (single/married). You must notify the organization if you qualify.
