Arizona rules for bonuses
Employee-elected percentage (Form A-4). Published rates: 2% for default if no Form A-4 (employee may elect 0%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0% or 3.5% of gross taxable wages).
- No separate supplemental rule. A.R.S. 43-401(A) applies withholding to 'wages, salary, bonus or other emolument', so the bonus is withheld at the employee's A-4 percentage
- Employee may add an extra amount per paycheck
Arizona income tax withholding is a percentage of gross taxable wages... the employer must withhold Arizona income tax at the default rate, 2.0% of the employee's wages until the employer receives a completed Form A-4 (2026 A-4 instructions)
Local taxes: None (local income taxes preempted)
