U.S. Resident Withholding Tax Generally, you want about 90% of your estimated income taxes withheld and sent to the government.
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.
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.
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%.
Withholding taxes from monthly benefits is usually voluntary and can be requested through IRS Form W-4V. Amounts generally range from 7% to 25%.
