For Arizona individual income tax refund status by phone, ADOR says taxpayers can call 602-255-3381 and, after making the language selection, choose Option 2 for refund status. Taxpayers should have the Social Security number, ZIP code and filing status reported on the return ready.
Check refund online first

Calling without the correct filing status, ZIP code and taxpayer details can slow the conversation.

Arizona Business and Corporate Tax Phone Help: TPT, Use Tax, Corporate Income and Withholding
Arizona businesses often need more than one tax account or filing path. A business may need TPT licensing, corporate income tax filing, withholding responsibilities, use tax reporting, AZTaxes.gov access, city/county licensing and federal IRS records. ADOR customer care can help identify the right state tax path, but final filing must follow the official tax-type rules.
Business owners should check
- Whether the business needs an Arizona TPT license.
- Whether the business has more than one Arizona location.
- Whether electronic filing is required.
- Whether consumer use tax or seller use tax applies.
- Corporate or small business income tax payment rules.
- Payroll withholding and unemployment-related obligations through the correct agency.
- City, county and industry permits outside ADOR.

- Prepare TPT license number or account number.
- Know the tax type and filing period.
- Have AZTaxes.gov username/email and error message if online access is the issue.
- Have notice, assessment or payment confirmation in front of you.
- Do not assume federal IRS, city licensing and ADOR account rules are the same.

Arizona DOR Notice, Letter, Assessment or Tax Correction: What To Do Before Calling
An ADOR letter can involve refund review, missing information, identity verification, tax correction, TPT account matters, a balance due, collection, audit, assessment, lien or AZTaxes.gov account issue. The fastest call is usually the one where you have the letter and the exact tax period in front of you.

- Identify the tax type: individual income, TPT, corporate, withholding, use tax or collections.
- Write down the notice number, assessment number or letter ID.
- Gather return copies, payment confirmations and supporting documents.

- Keep copies of anything mailed, uploaded or faxed.
Common notice mistakes
Common mistakes include calling without the notice, paying the wrong period, replying after the deadline, assuming the issue is a refund delay when it is actually identity verification, or sending documents through normal email when the official instructions require a different submission method.
