Forgot to sign tax return and was sent a refund check

[Czayce]

So my husband and I filed our taxes and they were returned to us 2 weeks ago stating we forgot to sign them. 

However, we've now just received a tax refund check very close (but not the same) to what we paid them when we mailed in our tax return originally. Once they get our return back with the signature, will we then owe them again the money they've just returned to us?

Funny as it may seem ... the payment went to one department and the return to another.  Since the return did not get processed fast enough the payment was returned to you.  Now when you sign the return you need to send the payment back with a note explaining that is was erroneously returned to you.

That makes sense, but what doesn't make sense is that the returned check is $100 more than the amount they took as payment.

Even sadder ... taxable interest because they held the money beyond the standard period.   I am surprised  you didn't get a letter asking you what you wanted to do with it before you got the refund.  Wait until you get the IRS form letter  in January reminding you to put the interest on the return.

I wonder if we can just send it with the tax return (sending it back tomorrow, signed).. and just write void on it.

Even better ... if you still have the check DO send it back.

Will do. Thank you so much!
