Once your returns have been accepted , it is up to the IRS & State when refunds are issued. The IRS states that nine out of 10 e-filed tax returns with direct deposit will be processed within 21 days of IRS e-file acceptance. There are delays with returns that include the ECI/ACTC credit, the IRS states that deposit dates should start showing sometime this week.
Mailed paper returns: If you filed a paper return, please allow 4 weeks before checking the status. Refund processing time is 6 to 8 weeks from the date the IRS receives your tax return.
States differ when they issue refunds.
