If your refund amount is less than expected, the IRS will send you an explanation in the mail approximately 2 weeks after your refund is deposited. This notice will detail any adjustments made to your refund, such as offsets for unpaid debts (e.g., past-due child support, federal student loans, or other government obligations) or corrections to your return.
Additionally, ensure that your direct deposit information was entered correctly on Form 1040, lines 35b through 35d. The account number must be up to 17 characters (letters and numbers), include hyphens if applicable, and exclude spaces or special symbols. If you requested a split refund using Form 8888, verify that the form was properly attached and completed.
For real-time tracking, use the IRS2Go app or visit IRS.gov/Refunds and enter your Social Security number, filing status, and the exact refund amount. Information is typically available within 24 hours of e-filing or 4 weeks after mailing a paper return.
