Processing timer a refund return depends on the method used for filing. If you e-file opting for direct deposit and have not received your refund within 3 weeks after filing your return (eight weeks if you filed a paper return opting for a paper check), you can check your refund status by clicking on "Where's My Refund" then go to "Get My Refund Status" (after inputting the required data). Or, you can call the Refund Hotline at (800) 829-1954. Be sure to have available a copy of your current tax return because you will need to know your social security number shown on your return, the filing status and the exact whole dollar amount of your refund. If you have requested direct deposit, the refund should take one week less time to be issued as opposed to getting a paper check.
