Overview

Arizona employers who withhold state income tax from employee wages must file returns with the Arizona Department of Revenue (ADOR).

The TaxBandits API supports the automation of Form A1-QRT, Arizona's quarterly withholding tax return.

Forms supported​

FormTypeFiling frequencyDue date
Form A1-QRTWHQuarterlyLast day of the month following the quarter end: April 30, July 31, October 31, January 31

Key compliance notes​

  • Zero filing required. Form A1-QRT must be filed every quarter, including quarters with no withholding liability, until the withholding account is canceled.
  • Payment separate from filing. Form A1-QRT reports withholding for the quarter; it does not replace the employer's separate deposit schedule (monthly, semi-weekly, or quarterly).
  • Final returns. Employers closing their withholding account must indicate a final return and cancellation date.

Before filing, you can simulate the entire verification flow in our Sandbox environment without submitting real data to state agencies. See how
