Due to heavy submissions volume and tax season opening two weeks later than usual, ADOR technical staff are actively working towards accepting and processing individual income tax returns as soon as possible. We will inform you when your return has been accepted for processing. Thank you for your patience and we apologize for any inconvenience.
Customer Notice: Due to COVID-19, ADOR's in-person lobby services are by appointment only and in compliance with local municipal and county face covering policies.
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.
To find the CTDS number for a public school in Arizona, please visit the Arizona Department of Education’s webpage at: http://www.ade.az.gov/edd or visit our website for a list.
