QuickBooks and Arizona Form A1-QRT: What Prefills and What You Must Enter
QuickBooks prefills most of Arizona's quarterly withholding return, but the liability schedule sections trip up employers who confuse payments with tax owed.
Arizona employers filing Form A1-QRT — the Quarterly Withholding Tax Return — through QuickBooks often run into confusion over which fields the software completes automatically and which require manual entry. The bigger stumbling block, though, is the liability schedule: QuickBooks does not always make it obvious which parts apply to a given employer, and the form requires reporting tax liability amounts, not the amounts actually paid.
What QuickBooks Fills In
When you launch the A1-QRT form from within QuickBooks, most fields arrive already populated with data drawn from your company file. Employee wages, Arizona state income tax withheld, and employer information typically carry over without manual intervention. The form flags any line that still needs input with an alert indicator — those are the only lines where you need to type an amount or enter a zero.
In practice, if all payroll, employee, and company data has been entered correctly throughout the quarter, there is little left to fill in by hand. The form window includes a Help button for general navigation questions and for troubleshooting specific issues with the form itself.
The Critical Distinction: Liability vs. Payments
The most common point of confusion centers on Parts II and III of the form. Arizona requires employers to report their withholding tax liability — the amount of tax that was owed based on wages paid — not the amount of tax actually remitted to the state. These two figures can differ, especially if a payment was late, short, or applied to a different period.
QuickBooks does not flag this distinction on the form itself, so it falls to the person filing to make sure the right numbers go on the right lines.
Determining Your Filing Frequency
Before completing the form, you must determine your withholding liability schedule. Arizona assigns employers to one of three tiers, and the correct tier determines which sections of the form you complete.
Quarterly Filers
Employers with a quarterly withholding liability complete Part IIA (Quarterly Tax Liability) and Part III, line 1. Enter the total Arizona withholding tax liability for the quarter. Do not complete Part IIB (Monthly Tax Liability) or Part IV (the Daily Tax Liability Schedule).
Monthly Filers
Employers with a monthly liability for all three months of the quarter complete Part IIB for each of the three months. Enter the liability for each individual month — again, not the payment amounts. Add the three monthly subtotals and enter the combined figure on line B4. Then carry the total quarterly liability to Part III, line 1.
Semi-Weekly or One-Banking-Day Filers
Employers in this category have the most complex filing. You must complete all three sections (A, B, and C) of the Daily Tax Liability Schedule — covering months one, two, and three respectively — plus Part IIB (Monthly Tax Liability) and Part III, line 1. On the daily schedule, enter the liability amount on the specific day that wages were paid and an Arizona withholding liability was incurred. After filling in the daily entries, total each month’s column and carry those subtotals forward.
Navigating to the Form in QuickBooks
To access the A1-QRT, go to the Employees menu, select Payroll Forms, then Process Payroll Forms. Choose Arizona Form A1-QRT from the list of available state forms. QuickBooks will walk through an interview-style setup, pulling data from your payroll items and employee records. Review each screen carefully — particularly the liability schedule — before filing.
If you need to verify where a specific number on the form originated, the form window provides hyperlinks that trace amounts back to their source in your QuickBooks data. For employers who want to cross-check figures outside of QuickBooks, the software also supports exporting a payroll summary to a spreadsheet, and the completed form can be saved as a PDF for your records.
What to Watch For
The form’s structure means that completing sections that do not apply to your filing frequency — or entering payment amounts instead of liability amounts — are the two most likely errors. Both can trigger discrepancies with the Arizona Department of Revenue. Before filing, confirm your assigned schedule, verify that only the applicable sections are populated, and double-check that every figure represents tax owed, not tax remitted.
