I spoke with my employees when I saw it wasnt withholding anything to make sure they were aware (because sadly this generation of workers never look at their pay stubs or keep up with their hours). I figure the reason the gov changed it is 1 they are tired of sending out high refund checks and 2 they love to keep it complicated. This way they also had opportunity to adjust it (just as they had in the past). I also let them know that getting the advance child tax credit throughout the year would effect their refund and that they just should know that. Its a matter of having it now or later. only 1 didnt listen and they wound up owing. ... you can lead a horse to water, but you can make them drink.
