QuickBooks Arizona Form A1-QRT: Withholding Amounts and Filing Confusion
Arizona employers using QuickBooks payroll report confusion over how Form A1-QRT withholding amounts are calculated and which liability sections apply.

QuickBooks users handling Arizona payroll taxes have raised questions about how the state’s quarterly withholding return — Form A1-QRT — pulls its numbers together and which sections of the form they are responsible for completing. The confusion centers on pre-filled data, liability classification, and the distinction between tax liability and tax payments.
How QuickBooks Handles A1-QRT
QuickBooks prefills most fields on Form A1-QRT automatically using the payroll data already entered throughout the quarter. In the typical scenario where all company, payroll, and employee information has been recorded properly in QuickBooks, users generally do not need to manually enter additional figures. The software flags any lines that still require input with an alert, and users need only fill in those flagged fields — entering amounts or zeroes as appropriate.
The form itself is used to report information to the Arizona Department of Revenue for all employees who worked during the quarter. Unless the taxpayer has a waiver or is exempt, the form must be e-filed.
Understanding Withholding Amounts
A common point of confusion is how the withholding amounts on the form are derived. QuickBooks draws these figures from the payroll data already in the system — the same withholding amounts recorded on employee paychecks throughout the quarter. Users looking to verify or audit those numbers can use QuickBooks’ built-in help features, including hyperlinks within the form window that explain where each figure originated.
For those who want to review their payroll data in a different format, QuickBooks also supports summarizing payroll information in a spreadsheet, which can be useful for cross-referencing the figures appearing on A1-QRT before filing.
Determining Your Liability Schedule
The most critical step is determining which withholding liability category applies to the employer, because that dictates which sections of the form must be completed. Employers fall into one of three classifications: quarterly, monthly, or daily (semi-weekly or one banking day). Users must check the appropriate box on the form and then complete only the sections that correspond to their classification.
Quarterly Filers
Employers with a quarterly withholding tax liability complete Part IIA — the Quarterly Tax Liability section — and Part III, line 1. The key detail here is that the amount entered should reflect the Arizona withholding tax liability for the quarter, not the amount of withholding payments made. Part IIB, Part IV, and the Daily Tax Liability Schedule should not be completed by quarterly filers.
Monthly Filers
Employers with a monthly withholding liability for all three months of the calendar quarter must complete Part IIB — the Monthly Tax Liability section — for each of the three months. Again, the figures entered should represent tax liability, not payments. The three monthly subtotals are added together and placed on line B4, and the total quarterly liability is entered on Part III, line 1.
Semi-Weekly and One-Banking-Day Filers
Employers in this category have the most extensive filing requirements. They must complete sections A, B, and C of the Daily Tax Liability Schedule, Part IIB for monthly liability, and Part III, line 1. On the Daily Tax Liability Schedule, entries are made for each day an Arizona withholding tax liability was incurred, with the liability amount recorded for that specific day — not payment amounts.
Saving and Reviewing the Form
Once the form is complete, users can save a copy as a PDF for their records. This is recommended for documentation purposes, particularly given the complexity of the liability schedules and the importance of retaining accurate filing records.
For general help navigating the form window or troubleshooting specific issues, QuickBooks provides a Help button directly within the form interface. Users who encounter problems with payroll data not flowing correctly into the form may benefit from reviewing their payroll setup and troubleshooting resources.
Key Takeaway
The most common pitfall is entering payment amounts where liability amounts belong. QuickBooks is designed to handle the calculations and pre-fill most of the form automatically, but the employer must correctly identify their liability classification and ensure that any manually entered figures reflect tax liability — not amounts paid.
