Store wants to take money from our tax returns (NJ)

My owner just informed all of the employees that he did not pay enough taxes on the store and that it will be mandatory for all of the employees to give part of their tax return back to the store to make up for it.

I was just curious as to whether or not it is legal for them to take any of our tax money or if they're required to show or give us any type of paperwork as proof that we are supposed to give some of it in. Thank you in advance!

TL;DR store owner did taxes incorrectly, is requiring employees to pay for it...I think?
