We are still having the same problem as well. My payroll updates are always up to date. Employees are entered correctly. When I pull the 15-T form from the IRS to see what quickbooks should be calculating, Quickbooks is incorrectly calculating Federal withholding (low amount) or not withholding at all. Anyone with 2019 W-4 and earlier are completely fine but anyone who has filled out a 2020 or later W-4 and we have switched it over in Quickbooks, they are being calculated incorrectly! This is ridiculous, this has been going on for over a year now to no resolution. I have also contacted customer service and got no definite answer or resolution after they remote accessed my quickbooks. I was told maybe it is because of this or maybe it is because of that. I am not getting anywhere and this needs to be fixed or a bunch of customers will go with another accounting software!! I need to be contacted when this is resolved.
