AZ HB2222

Removes dollar caps and limits on school tuition tax credits under sections 43-1089, 43-1183, and 43-1184, allowing unlimited contributions and credits instead of previous restrictions ($500 for individuals, $1,000 for joint filers).

Eliminates the $10 million aggregate cap on combined tax credits under sections 43-1089 and 20-224.06, and removes the $5 million aggregate cap on combined credits under sections 43-1184 and 20-224.07.

Maintains preapproval requirements where taxpayers must notify school tuition organizations of intended contribution amounts and receive department of revenue approval before making donations to receive tax credits.

Preserves restrictions preventing taxpayers from designating contributions for specific students or dependents and prohibits coordination between taxpayers to swap donations for mutual benefit.

Updates provisions governing school tuition organizations, qualified schools, and insurance premium tax credits to align with the removal of contribution and credit caps.
