After you file

If you did not pay any fees out of your Federal refund, then the only two parties involved are the IRS and your bank. 

Did you print out your return and look at the routing and account numbers to be sure they are correct?

You can phone the IRS, and they should be able to tell you to what bank they sent the funds.

IRS:  800-829-1040  hours 7 AM - 7 PM local time Mon-Fri

  • Then press 3 "for all other questions."
  • Then press 2 "for all other questions."  It should then transfer you to an agent, but there is likely to be a long wait.

I usually use a speakerphone so I can work on something else while waiting.
