WMR on IRS.gov and the IRS2Go app will be updated with projected deposit dates for most early EITC/ACTC refund filers by February 22. So EITC /ACTC filers will not see an update to their refund status for several days after Feb. 15.
The IRS expects most EITC/ACTC related refunds to be available in taxpayer bank accounts or on debit cards by the first week of March, if they chose direct deposit and there are no other issues with their tax return.
