current year. Arizona tax liability is gross tax liability less any
tax credits, such as the family tax credit, school tax credits, or
credits for taxes paid to other states. If you make this election,
your employer will not withhold Arizona income tax from your
wages for payroll periods beginning after the date you file the

give your employer an updated Form A-4. If you do not, your
employer may withhold Arizona income tax from your wages
and salary until you submit an updated Form A-4.
Zero withholding does not relieve you from paying Arizona
income taxes that might be due at the time you file your Arizona
income tax return. If you have an Arizona tax liability when
you file your return or if at any time during the current year
conditions change so that you expect to have a tax liability, you
should promptly file a new Form A-4 and choose a withholding
percentage that applies to you.

    Your “gross taxable wages” are the total wages before any deductions, which are typically reported in box 1 of your federal Form W-2. This amount is your gross income minus any pretax deductions, like health insurance premiums.

  4. Can I elect a withholding percentage of zero?

    Yes, you can elect a withholding percentage of zero if you expect to have no Arizona tax liability for the current year. However, if your tax situation changes and you do have a tax liability, you should submit a new A4 form to select an appropriate withholding percentage.

  5. What should I do with the completed A4 form?

    After completing the A4 form, you should give it to your employer. This ensures that they have the correct information to withhold the appropriate amount of state income tax from your paychecks.

  6. What happens if I don’t submit the form?

    If you do not submit the A4 form, your employer will automatically withhold 2.7% of your gross taxable wages. This may not align with your actual tax liability, so it’s important to complete the form to reflect your specific situation.

Common mistakes

Filling out the Arizona A4 form can be a straightforward process, yet many individuals encounter pitfalls that can complicate their tax situation. One common mistake is failing to provide accurate personal information. This includes not only the full name but also the correct Social Security number. Any discrepancies can lead to delays in processing and potential issues with tax liabilities.

Another frequent error occurs when individuals do not select the appropriate withholding percentage. The form allows for various options, and it is crucial to choose only one. Checking multiple boxes can create confusion and may result in incorrect withholding amounts, leading to unexpected tax bills or refunds.

Many people overlook the importance of certifying their election accurately. When opting for a withholding percentage of zero, it is essential to ensure that the certification aligns with their actual tax liability expectations. Misjudging this can lead to under-withholding, resulting in a tax bill at the end of the year.

In addition, failing to submit the form within the specified timeframe can be detrimental. New employees must complete the A4 form within the first five days of employment. If this deadline is missed, the employer is required to withhold at the default rate of 2.7%, which may not reflect the employee's actual tax situation.

Current employees wishing to change their withholding amounts often make the mistake of not filing a new form in a timely manner. If there are changes in income or tax liability, it is important to submit an updated A4 form promptly. Delays can lead to continued withholding at the previous rate, which might not be suitable.

Another oversight involves the lack of clarity regarding gross taxable wages. Individuals may not fully understand what constitutes gross taxable wages, leading to incorrect calculations when determining withholding amounts. It is vital to comprehend that gross taxable wages are the wages reported in box 1 of the federal Form W-2, minus any pretax deductions.

Furthermore, some may neglect to consider their eligibility for tax credits when electing a withholding percentage of zero. Understanding one's tax situation is crucial, as claiming this option without proper justification can result in a tax liability that must be settled later.

Nonresident employees also face unique challenges when completing the A4 form. They may not realize their eligibility for withholding exemptions or fail to understand the implications of their work status in Arizona. This misunderstanding can lead to incorrect withholding, impacting their overall tax obligations.

Lastly, individuals often forget to keep a copy of the completed A4 form for their records. Retaining a copy is essential for future reference, especially if questions arise regarding withholding amounts or tax liabilities. Documentation serves as a safeguard against potential discrepancies with the IRS or state tax authorities.

Documents used along the form

The Arizona A4 form is essential for employees in Arizona to determine their income tax withholding preferences. Along with this form, there are several other documents that may be relevant to employees and employers. Here are four commonly used forms and documents:

  • Arizona Form W-4: This form is used by employees to indicate their federal tax withholding preferences. It helps employers calculate the correct amount of federal income tax to withhold from an employee's paycheck.
  • Arizona Form W-2: Employers use this form to report an employee's annual wages and the amount of taxes withheld. Employees receive this form at the end of the tax year to help them file their income tax returns.
  • Arizona Form 140: This is the individual income tax return form that residents use to report their income and calculate their tax liability. It is essential for filing taxes annually.
  • Arizona Form 140NR: Nonresidents use this form to file their income tax returns if they earned income in Arizona but are not residents of the state. It ensures that nonresidents pay the appropriate taxes on their Arizona-sourced income.

Understanding these forms can help employees manage their tax obligations effectively. It is crucial to keep all relevant documents updated to avoid any issues with tax withholding and filing.
