Arizona Form A1-QRT Withholding Return in QuickBooks
How QuickBooks handles Arizona's quarterly withholding tax return, what gets prefilled, and which liability sections employers must complete.
QuickBooks Desktop includes built-in support for Arizona Form A1-QRT, the Quarterly Withholding Tax Return that employers file with the Arizona Department of Revenue. The form pulls payroll data already stored in the company file, but users still need to understand which sections apply to their withholding schedule — and the distinctions matter, because completing the wrong liability section is a common point of confusion.
What QuickBooks Fills In Automatically
When you open the A1-QRT form, QuickBooks prepopulates most fields using the company, payroll, and employee data already on file. In many cases, if all records are current and accurate, the form requires little to no manual entry beyond reviewing what appears on screen.
The areas that do need your attention are typically flagged with an alert. Those are the lines where you may need to enter amounts — or zeroes — depending on your situation. Everything else should reflect the withholding data QuickBooks has been tracking throughout the quarter.
Determining Your Filing Schedule
Before completing the form, you must identify your withholding liability category. Arizona recognizes three schedules: quarterly, monthly, and daily — which encompasses both semi-weekly and one-banking-day filers. You check the appropriate box on the form to indicate which applies.
This determination drives which parts of the form you complete, and it is not optional. An employer with quarterly liability fills out different sections than one with monthly or daily obligations.
Completing the Correct Liability Section
The form is structured so that you complete either Part A or Part B — not both — depending on your schedule.
Quarterly Filers
Employers with quarterly withholding tax liability complete Part IIA, which covers quarterly tax liability, along with Part III, line 1. The critical detail here is that you enter withholding tax liability amounts, not the amounts actually paid during the quarter. QuickBooks users who confuse payments with liability will enter incorrect figures.
Monthly Filers
Employers with monthly liability for all three months of the quarter complete Part IIB, entering the liability for each individual month. The three monthly subtotals are then combined and entered on line B4, with the total quarterly liability also appearing on Part III, line 1.
Daily (Semi-Weekly or One-Banking-Day) Filers
This is the most involved scenario. Employers in this category must complete sections A, B, and C of the Daily Tax Liability Schedule, Part IIB for monthly liability, and Part III, line 1. The daily schedule requires entries on each day an Arizona withholding liability was incurred — again using liability amounts, not payment amounts. Monthly totals from the daily schedule carry over to Part IIB, and the combined total flows to line B4 and Part III.
One important rule: a monthly filer that triggers a one-banking-day payment obligation immediately becomes a semi-weekly filer for the rest of the quarter. QuickBooks does not automatically reclassify you, so you need to be aware of this shift.
Federal Threshold Flag
If your business incurred a federal withholding tax liability of $100,000 or more on any single day, the corresponding day on the Daily Tax Liability Schedule will be checked. This is a federal threshold that carries implications for state filing frequency, and QuickBooks flags it on the form.
E-Filing Requirement
Arizona requires Form A1-QRT to be e-filed unless the taxpayer has an approved waiver or qualifies for an exemption. QuickBooks supports electronic filing of the form, which aligns with the state’s submission requirement.
Key Takeaway for Employers
The most common pitfall is entering payment amounts where liability amounts belong. Throughout every section of A1-QRT — whether quarterly, monthly, or daily — the form asks for tax liability incurred, not amounts remitted. QuickBooks prefills based on the data it has, but the responsibility for confirming that the right figures land on the right lines rests with the employer.
