Our tax returns have not yet been accepted (after e-filing) by the IRS. They were filed on March 26 (3 days ago), and we are not getting refunds. Why the delay?

It can usually take anywhere from 24-48 hours, however this year it seems to be taking much longer for returns to get accepted and begin processing. Until the IRS starts processing it on their own, you may not find record of it or the website may say that you have put in incorrect information when tracking your federal refund. As your return moves through the system, the status of it will be updated accordingly.
