I filed my taxes 1/22/19 and still have not received my return. When can I expect it?

If you efiled, double-check with this tool to be sure the return was efiled successfully and accepted:

If that showed it was accepted (or if you mailed the return), what do you see at the IRS website below for the status of your Federal refund?

If that IRS tool shows that the refund has been sent, but you didn't receive it, report back for more info.  

If the IRS tool says it is still "being processed", we can tell you how to speak to a live agent at the IRS to see if they can tell you anything about the delay.   And, if necessary, the IRS Taxpayer Advocate Service to see if they can assist you.
