Outstanding Liabilities and Refund Offsets

Outstanding Liabilities

Taxpayers who receive a letter from ADOR, informing them that some or all of their refund was adjusted to pay outstanding liabilities with the Internal Revenue Service (IRS), courts, state agencies or government municipalities, should note that, by law, we must offset any refunds or overpayments to certain authorized agencies that have a claim against them.

Those individuals who receive notice can contact the agency listed on the ADOR Offset letter if they have any questions about the claim or offset. If a tax refund has been withheld in error by a court or agency, a taxpayer has 30 days from the date of the letter to file an appeal with the court or agency claiming the refund. The taxpayer will be entitled to the full refund, plus interest and penalties, per Arizona Revised Statute § 42-1122.

If a refund was offset by the IRS, a taxpayer must allow 6-8 weeks from the letter for processing. However, the taxpayer should not contact ADOR regarding his or her federal tax. Any questions about the IRS offset must be addressed by the IRS.

Note: If additional amounts from this refund are used to pay a debt owed to another government agency, the letter notification will display all agencies that have offset the tax refund for the same tax year.

Refund Offsets

If a taxpayer and/or spouse owe money to the Arizona Department of Revenue or another agency, the amount may be deducted from an expected refund. ADOR offsets as much of the refund needed to pay off overdue taxes owed by taxpayers and notifies them when this occurs.

The Debt Set-Off Office also offsets taxpayers’ refunds to pay off past due child support or federal agency debts, such as student loans. Offsets to non-tax debts occur after ADOR has certified the refunds and before making direct deposits or issuing paper checks.

Refund offsets reduce the amount of the expected direct deposit or paper check and will delay the issuance of the remaining refund (if any) after offset. Taxpayers who owe non-tax debts may contact the agency they owe prior to filing their returns to determine if their debts were submitted for refund offset. ADOR cannot determine, prior to the filing of a return, whether refunds will be offset for non-tax debts.

ADOR sends taxpayers offset notices if any part of their refund is applied to non-tax debts. Taxpayers should contact the agencies identified on the offset notice when offsets occur and they wish to dispute the non-tax debts, or have questions about the offsets.
