The IRS estimates that most refunds will be sent within 3
weeks after your e-filed returns are accepted. As your return moves through the
process, Where's My Refund will be updated accordingly. There's no way of
knowing exactly when the IRS will update to refund sent. You will need to keep
checking the Where’s My
Federal Refund? tool for updates. Updates
are made daily, usually overnight.
