Arizona has one of the most generous and longest-running state education tax credit programs in the country, allowing individual taxpayers to redirect a portion of their Arizona state income taxes — dollar for dollar — directly to a School Tuition Organization (STO) that funds private school scholarships for K-12 students, at no out-of-pocket cost. Arizona offers two tiers of credit: the Original STO Credit of up to $787 for single filers and $1,570 for married filing jointly, plus the Switcher (Overflow) Credit of up to $784 for single filers and $1,561 for married filing jointly — meaning a married couple can potentially redirect up to $3,131 in Arizona state taxes annually to fund educational scholarships. Unlike a charitable deduction, every dollar contributed reduces your Arizona tax bill by the same dollar, making this one of the most efficient tax planning tools available to Arizona residents.
