My colleague was telling me that her refund amount was actually different when she got it in the mail, than what she had submitted. There was no refund offset either. How often does this happen?
Refunds may be different if the Refund Processing Service was used to pay the TurboTax Online fees. If that is so, TurboTax fee plus the additional processing fee is deducted from the federal tax refund. You may also see a change in your refund amount because the IRS made an adjustment/change to the tax return.
You can contact the IRS if you have more questions regarding a tax return/refund at 1-800-829-1040, but prepare for potentially long wait times.
