Refund Offset
Your Federal Refund
may have been Offset by the IRS.
A refund offset
is when an IRS refund is reduced or intercepted to pay off
delinquent debt, such as past-due child support, outstanding student loans, or
unpaid state income tax.
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).
