How Your AZ Paycheck Works

Arizona paychecks start with federal income tax withholding using the employee's Form W-4 inputs and IRS 2026 wage-bracket or percentage-method tables in Publication 15-T. FICA is separate: employee Social Security is 6.2% on 2026 wages up to $184,500, and Medicare is 1.45% on all covered wages with no wage cap. Employers must also withhold 0.9% Additional Medicare Tax when an employee's Medicare wages exceed $200,000 in the calendar year. Arizona's state income tax is flat at 2.5% of taxable income under current Arizona statute; AZDOR withholding guidance lets employees elect a withholding percentage on Form A-4, including 2.5%. Arizona does not have a statewide employee-paid disability insurance or paid family leave payroll tax that affects standard wage withholding. Estimates assume standard 2026 withholding, single filing status, and no pre-tax deductions; actual paycheck may differ.
