Note: If you are also expecting a refund for your state return it will come separately from your federal refund.
If you believe you do not owe the
debt or you want to dispute the amount taken from your refund, you should
contact the agency that received the offset amount.
If you have questions regarding the offset of your federal tax refund or offset of another U.S. government-issued payment, you can call the Treasury Offset Program (TOP) Call Center to obtain agency contact information during our customer service hours . Call 800-304-3107
