Arizona Income Taxes & Refunds
About $1.2 billion of Arizona's general budget comes from individual income taxes. Some 2.7 million people file income taxes in the state every year.
AZ Income Tax Rates
The Arizona Department of Revenue (DOR) is responsible for handling state income taxes. If you're single, married filing separately or filing as head of household, you must file if your adjusted gross income (AAGI) is at least $5,000 or if your gross income (GI) is at least $15,000. If you're married and filing jointly, you must file if your AAGI is at least $11,000 or your GI is at least $15,000.
The tax rate in the state for individuals runs between 2.59 and 4.54% depending on your income. Most individuals need to file a form 140 or 140EZ. partial-year residents and non-residents with AZ income sources must also file.
Arizona Tax Payments
Individual income taxes and payments are due on April 15. You can request a six-month extension to file your taxes by sending a form 204 to the DOR. However, there is no extension to pay. You must pay at least 90% of the taxes you owe by April 15 to avoid penalties.
You can file online or (when making a payment) by mailing the forms to Arizona Department of Revenue at:
P.O. Box 29085
Phoenix, AZ 85038-9085
To Amend a Return
If you want to amend a return from a previous year, you must file a form 140X. You must mail in a copy of your amendment. Mail your forms to:
Arizona Department of Revenue
P.O. Box 52138
Phoenix, AZ 85072-2138
Where's My Refund?
Use the "Where's My Refund?" system at Aztaxes.gov to track your return. You'll need to provide the filing year, your social security number, filing status and zip code. You can find out about the status of an amendment by calling 800-352-4090.
If you don't pay your Arizona taxes on time, you'll pay a penalty of 4.5% on the balance due every month for which your return is late. If you file on time but pay your taxes late, you'll pay a penalty of half a percent on the balance due every month your payment is late. Unpaid tax balances also accrue interest at the same rate as unpaid federal taxes.
