You can begin to track your refund on the IRS website 24hrs after your return has been accepted.
To check your refund status on the Where's My Refund? site, you will need your social security number, filing status, and refund amount in order to track your refund. Be sure to enter only the Federal Refund amount and not the total amount that includes the State refund. The amount to enter is on your Federal form 1040, line 21a.
If you paid any fees out of your Federal refund, use the refund figure prior to the deduction of the fees.
