Arizona issued an updated withholding certificate, A-4, to reflect its lower individual income tax rates. The lower rates range from 0.5%-3.5%, with the familiar options to withhold 0% or add additional withholding. All employers are mandated to provide this form to their Arizona employees by January 31, 2023.
Single or Married Filing Separately: This status should be used if you are either single or married but filing separately. Married Filing Jointly (or Qualifying Widower): This status should be used if you are married and filing a joint tax return with your spouse.
To change the amount of Arizona income tax withheld, an employee must complete Arizona Form A-4 and submit to his or her employer to choose a different withholding percentage. Employees may also request to have an additional amount withheld by their employer.
Note: Under-withholding can result in you owing tax and/or underpayment penalties when you file your Arizona return at the end of the year. For tax year 2023 and beyond, the tax rate for Arizona taxable income is 2.5%.
Use the Tax Withholding Estimator on IRS. The Tax Withholding Estimator works for most employees by helping them determine whether they need to give their employer a new Form W-4. They can use their results from the estimator to help fill out the form and adjust their income tax withholding.
In general, married couples who file their taxes jointly will have less withheld from their paychecks than single filers.
Fill out your personal details, including your name, address, Social Security number, and filing status. Your filing status determines your eligibility for tax credits and deductions. You can select single, married filing separately, married filing jointly, qualifying surviving spouse, or head of household.
The new default Arizona withholding rate is 2.0%. What if the employee wants their Arizona taxes to be overwithheld? 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.
