Sometimes, your federal refund can take longer than 21 days to process. (See the FAQ below for reasons why this may occur).
Note: An IRS representatives will be able to research the status of your refund since your return was accepted more than 21 calendar days ago. Call them at 1-800-829-1040, but prepare for potentially long wait times.
