The IRS estimates that most refunds will
be sent within 3 weeks after your e-filed returns are accepted. Many refunds
will come sooner. 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.
