Where to Mail Your AZ Tax Return: Key Addresses and Tips

Filing your Arizona tax return correctly is crucial to avoid delays or issues with processing. Knowing where and how to mail your documents ensures they are handled efficiently by the Arizona Department of Revenue.

This guide outlines key mailing addresses, required enclosures, postmark criteria, and tracking methods to help you file your taxes accurately.

Key Mailing Addresses

Mailing your Arizona tax return to the correct address is vital for smooth processing. The address you use depends on your payment situation and whether you are filing an amended return.

If Payment Enclosed

If your tax return includes a payment, send it to the designated payment address:
Arizona Department of Revenue, PO Box 52016, Phoenix, AZ 85072-2016.

Certified mail or a service with tracking is recommended to provide proof of submission.

If No Payment Enclosed

For returns without a payment, use this address:
Arizona Department of Revenue, PO Box 52138, Phoenix, AZ 85072-2138.

Businesses should verify their specific mailing requirements, as these differ based on the type of return.

Amended Returns

Amended returns should be sent to:
Arizona Department of Revenue, PO Box 52138, Phoenix, AZ 85072-2138.

Include a detailed explanation of the changes and any supporting documents to ensure accurate adjustments to your records.

Required Enclosures

Ensure all necessary documents are included with your submission. Individual filers should attach a copy of their federal tax return, along with W-2 forms, 1099s, or other income statements to verify earnings and withholdings. Business entities may need to include federal schedules or forms such as Form 1120 for corporations or Form 1065 for partnerships.

Postmark Criteria

The postmark date determines if your tax return meets the filing deadline, typically April 15th for individual taxpayers. Returns postmarked by the deadline are considered timely, even if received later. If the deadline falls on a weekend or holiday, it extends to the next business day. Certified mail provides a dated receipt, offering additional proof of timely mailing.

Tracking and Confirmation

Using tracking and confirmation services adds security to the filing process. Certified mail, USPS delivery confirmation, or private carriers like FedEx and UPS provide verifiable proof of delivery. These services include tracking numbers to monitor your submission. Electronic filing offers immediate confirmation from the state tax agency, speeding up processing and reducing uncertainty. Retain all receipts and tracking details in case of disputes regarding timing or delivery.
