According to the IRS website What to expect for Refunds This Year more than 9 out of 10 refunds are issued in less than 21 days after the IRS accepts the tax return when you e-file and choose direct deposit as your refund choice. Where’s My Refund? has the most up to date information available about your refund. The tool is updated daily (usually overnight) so you will just usually need to check once a day.
Now, taxpayers who claim the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit (ACTC) may experience a refund delay. The IRS usually begins issuing tax refunds on returns with the EIC or Additional Child Tax Credit in late February.
