The IRS releases most refunds within 21 calendar days
after the e-filed return has been accepted.
The "Where's My Refund" tool,
located at https://www.irs.gov/refunds, follows your tax return from
receipt to completion. It will tell you when your return is in received status
and if your refund is in approved or sent status.
