Have you seen the actual notice or are you just getting a client’s interpretation of a letter?

I've heard reports of it both here and on other boards.  Seems to be all over the place rather than a systemic issue (i.e. not all taxpayers who have their refunds 100% applied get it).  One preparer said they looked into it and the taxpayer made a ES payment they forgot to tell them about.  Another one included an underpayment penalty (most software defaults this to 4/15) but since the client paid earlier the penalty was lower and the IRS was looking to refund it.  For whatever reason, the IRS seems to think they are sending the taxpayer some money but they don't have an account on file.

The "we've changed your return" letters seem to be much slower than the "we want your bank account number" letters.  If you want to wait six weeks we can start taking bets on what will arrive first, a check from the U.S. Treasury or a letter from the IRS explaining why they're sending money.

Accessing the client's irs.gov account may shed some light on things (if the taxpayer can survive the id.me application).

Actually seen the notice.  Mark as best answer.....does it help anyone?  

"Mark as best answer.....does it help anyone?"

If someone has a really big ego, yes.  Other than that, it doesn't do a thing.  It doesn't even help to keep you out of the principal's office. 😀

I'm waiting to see if the refunds will include IRC 6611 interest if delayed more than 45 days . . .

Drew names from a bowl to see who had best answer since it wouldn't keep anyone out of principals office.  Thanks for the input only seen one letter but I had several leave money in the last two weeks and was curious what might happen.

Behaving yourself also keeps you out of the principal's office, but sometimes even when I try behaving I get a note telling me to report to the principal's office.  Don't tell anybody at Intuit, but I have started to dig an escape tunnel out of that office.  I think that two more visits will give me enough time to complete it.  🕳

Hey, that's my line, I've posted that several times already.  

@IRonMaN It's obvious from some of the answers by their employee "tax experts" that they have no principles, so I'm glad to know that at least they have a principal.  

I saw one. It also said they didn't have her bank info.

Overpayment was to be applied to 2026 estimated tax and 2026 estimated tax payments are to be direct debited so they do have her bank info.

I told client to ignore the letter.
