I am not so sure I fully believe this myself, as I just don't picture a lot of my clients keeping up on what Congress is doing regarding taxes, but almost all news stories about the Extenders bill say do not be in a rush to file.  Could that have anything to do with it?

In my business, the number of refundable child tax credit returns I do I can count on one hand with several fingers to spare.  But if you read the articles, I think I have only seen one which spelled out that this proposed change will only affect those with a liability less than the full child credit.  I have had two clients who apparently have read about the proposed bill ask me about how much more they would get if the law passed and when I told them nothing more for 2023, they didn't understand because they heard blah, blah, blah.

Anyway, I am just tossing this out as one possibility.
