General Instructions

To apply for an Arizona personal tax extension, use Arizona Form 204 (Application for Filing Extension). This will extend your filing deadline for 6 months for Form 140, 140A, 140EZ, 140ET, 140PTC, 140PY, or 140NR. Make sure you send in Form 204 by the original filing deadline of your return (typically April 15) to avoid late filing fees.

If you are approved for a Federal tax extension (IRS Form 4868), the Arizona Department of Revenue will automatically grant you a State extension for the period covered by your Federal extension. In this case, you do not need to submit Form 204.

File Arizona Form 204 if you need an Arizona State tax extension only or if you need to make an estimated tax payment with your extension. Individuals can remit tax extension payments by paper check, electronic check, money order, or credit card. Remember that a tax extension does not extend the deadline for any tax owed, which must still be paid by April 15 to avoid incurring Arizona’s underpayment penalty.

NOTE: Federal tax extensions are valid for a period of time (i.e. 3, 5, or 6 months) and extend an original Arizona deadline by the same period of time. In some cases, the Arizona extended deadline will take place after the Federal extended deadline.
