I noticed something on my federal tax refund check. Printed right under my name, it reads: 5.85 interest. I don't recall having ever seen this before but maybe it was there and I never noticed it before. Anyone have any idea what that means?

Is it saying they paid you, or you paid them?

It doesn't say either, just those words.

I believe that is the current annual rate of interest the IRS pays on refunds that are overdue.
