New Arizona Withholding Form

11-01-2022Tax Information

The Arizona Legislature substantially reduced Arizona's individual income tax rates for the 2022 tax year. The previous Form A-4 withholding rates are no longer representative of the new lower income tax rates. Employers should select the 2.0% default on behalf of the employee.

Employees will still have the option of selecting a higher Arizona withholding rate than their wages might dictate and there is still a line to add an additional amount of Arizona withholding.

For tax year 2022, there are two individual income tax rates, 2.55% and 2.98%. The new flat tax of 2.5% will affect the 2023 tax year – which is filed by April 2024.
