Part 3 - Tax Computation
Line 1 - Liability (Arizona Tax Withheld or Amount Required to be Withheld During the Quarter)
•Quarterly Depositors
Enter the amount from Part 2, Section A, line A1.
•Monthly and Semi-weekly Depositors Enter the amount from Part 2, Section B, line B4.
Line 2 - Payments Made during the Quarter
Enter the total amount of payments made for this quarter. If no payments were made prior to filing this return, enter “0”.
Do not include any payment that is made with this return (or for this return, if you are making a payment for an amount due for this return).
Line 3 - Total Amount Due
Subtract the amount on line 2 from the amount on line 1. Enter the difference.
If line 3 is a positive number, this is the amount of tax due. See the section, Payment of Tax, Penalties, and Interest, below for details on paying your tax due. If you owe any penalty or interest, the department will calculate these amounts and mail a billing notice after the return is processed. The entire amount of tax must be paid by the due date of Form A1-QRT.
If you are filing an amended return and that return shows a balance due, enclose the amount due with the amended return, unless your payment must be made by EFT. The department will send you a bill for any interest or penalty due once the amended return is processed.
If line 3 is a negative number (an amount less than zero), this is the overpayment for the quarter. Use a minus sign to indicate a negative amount. After the return is processed and payments are confirmed, the overpayment will be applied to any outstanding liabilities, possibly in another tax type. If the overpayment exceeds the outstanding liabilities or the employer has no outstanding liabilities, a refund check will be issued and mailed to the employer. A refund will not be issued once the overpayment is applied to a liability.
Payment of Tax, Penalties, and Interest
The entire amount of tax, penalties, and interest is due by the original due date of the return.
If payment is due, and the employer is required to pay by EFT, see the Section, How to Make EFT Payments, for instructions on paying your tax liability by EFT.
If payment is due, and the employer is not required to pay by EFT, you may elect to pay by EFT. Or you may pay by check or money order. If paying by check or money order, make the check or money order payable to the Arizona Department of Revenue.
Arizona Form A1-QRT Include the employer’s EIN on the front of the check or money order. Include the check or money order with your return.
NOTE: If this is an amended Form A1-QRT and you were 
required to make 2020 withholding payments by EFT, you must 
also pay any additional withholding tax due from the amended 
return by EFT. 
Part 4 – Semi-Weekly/Next-Day Deposit
Schedule
If you checked the box in Part 2, Schedule B, complete Part 4 for each month you are required to make withholding deposits on a semi-weekly schedule or you are required to make a federal next day deposit.
Enter the amount of Arizona withholding tax liability on the day (of the month) the liability was incurred. Do not enter the amount of the withholding payment(s). Enter the total withholding liability for the month on the line labeled “Month 1, 2, or 3.”
EXAMPLE: Taxpayer R is a semi-weekly depositor. It 
incurred an Arizona tax withholding liability on the following 
dates in January 2020: January 3 - $1,500; January 17 - 
$1,750; and January 31 - $1,600. In Schedule A, R enters 
$1,500 on line 3; R enters $1,750 on line 17; and R enters 
$1,600 on line 31. On the line labeled “Month 1 Liability.” R 
enters the total tax liability for January 2020 - $4,850. R also 
enters this amount on Part 2, Schedule B, line B1. 
Taxpayers with Next-Day Obligations: If you have a next- day obligation, check the box to the right of the day on which you incurred a next-day withholding obligation. If you do not have a next-day obligation, do not check the box.
EXAMPLE: Taxpayer R incurred an Arizona withholding tax 
liability on the following dates in February 2020: February 14 
- $2,350, and February 28 - $1,950. In addition, R incurred a 
federal next-day obligation on February 14. In Schedule B, R 
enters $2,350 on line 14, and checks the box on line 14 to 
indicate it incurred a next-day liability. R enters its February 
28 liability on line 28 and does not check the box on line 28 
because it did not incur a next-day liability. R enters its 
liability for February 2020 - $4,300 on the line labeled “Month 
2 Liability”. R also enters this amount on Part 2, Schedule B, 
line B2.
