The Wisconsin tax refund that was deposited to my bank account was about half of what TurboTax reported to the IRS. Why could this be and what can I do?

I have no debt and received no unemployment recently.

You might have a government refund offset. A refund offset is when an IRS refund is reduced or intercepted to pay off delinquent debt. 

You can contact the agency with which you have a debt to determine if your debt was submitted for a tax refund offset at 800-304-3107.

The Department of Treasury's Bureau of the Fiscal Service (BFS) issues IRS tax refunds and Congress authorizes BFS to conduct the Treasury Offset Program (TOP). Through the TOP program, BFS may reduce your refund (overpayment) and offset it to pay:

• Past-due child support;
• Federal agency non-tax debts;
• State income tax obligations; or
• Certain unemployment compensation debts owed to a state (Generally, these are debts for (1) compensation paid due to fraud, or (2) contributions owing to a state fund that were not paid).

You'll get an explanatory letter from the Bureau of the Fiscal Service if your refund is offset. The remainder of your refund will be processed as usual; an offset shouldn't delay it, unless of course your entire refund was applied to your debt.

More info about refund offsets, including contact info and the appeals process, is at IRS.gov (Tax Topic 203).

Thanks, although I am debt free and have not received unemployment recently.
If the IRS changed the amount is there a way to ask them what happened?
