The reason the tax return amounts might be different varies depending on each individual. According to the IRS, all or some of your refund may be used to pay outstanding funds owed, including:
- Past-due federal taxes
- State income tax
- State unemployment compensation debts
- Child support
- Spousal support
- Other federal debts (such as student loans)
