How the Arizona estimate works
Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Arizona withholding is the percentage of gross taxable wages elected on Form A-4, plus any additional amount the employee requested. If an employee does not submit Form A-4 within the required period, Arizona directs the employer to use 2.0%.
Example: The calculator keeps the Arizona percentage election separate from federal W-4 status. A 0% election is available only when that is the employee's actual Form A-4 election. The calculator does not assume any unentered benefit deduction or invent a tax result.
Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.
