Personal income taxes

Taxable income

How is taxable personal income determined in your state?

In Arizona, taxable personal income is based on an individual's federal adjusted gross income for the taxable year, subject to certain additions and subtractions, such as exemptions and deductions.

Tax residence

Under what circumstances is an individual deemed resident in your state for personal income tax purposes?

Every individual who is in Arizona for any purpose other than a temporary or transitory purpose is a resident. There is a presumption under Arizona law that every individual who spends, in the aggregate, more than nine months of the taxable year in the state is a resident. This presumption may be overcome by competent evidence that the individual is in the state for a temporary or transitory purpose. Arizona statutes do not define the terms ‘temporary’ and ‘transitory’. Arizona law further states that an individual who is domiciled in Arizona continues to be a resident even when they are temporarily absent from the state.

Rates

What are the applicable personal income tax rates?

Arizona’s individual income tax rates have always been graduated (progressive). The current levels range from 2.59% to 4.54%.

Filing requirements

What filing requirements and procedures apply?

The starting point for an individual is the individual’s federal adjusted gross income. An individual must complete a federal return before beginning Arizona Form 140 or 140EZ. For calendar-year taxpayers, the filing deadline is on or before April 15 following the close of the calendar year. Sole proprietors report business income on the Arizona individual income tax return.

Returns made based on a fiscal year should be filed on or before the 15th day of the fourth month following the close of the fiscal year (A.R.S. §43-325(2)).

For taxable years beginning from and after December 31, 2015, partnership returns are due on or before the 15th day of the third month following the close of the taxable year (A.R.S. §43-325(3)).

Employer obligations

What obligations are imposed on the employer in relation to the collection and remittance of state personal income taxes (eg, withholding)?

Arizona employers must withhold income tax from employee wages for services performed in Arizona. There are very few exceptions to the withholding requirement. The state income tax withholding is a percentage of the employee’s gross taxable wages. Withholding percentages are based on gross taxable wages. ‘Gross taxable wages’ is the amount that meets the federal definition of ‘wages’ contained in Internal Revenue Code (§3401). Withholding returns are filed quarterly on April 30, July 31, October 31, and January 31 for the preceding calendar quarter.
