So either The employer or IRS or both need to give out a tax bracket to the employee not everybody’s a tax genius and every year is different every tax deductions credits etc. change of jobs so yeah actually it is IRS and employer This is why the employer takes out the taxes that’s part of their responsibility. Because if not then why do they even have to fill out a W-4 form to begin with to give to the employer we as an employee would Just do all the handling’s through IRS an employee should just do that and work it with the IRS not the employer To note employers responsibility once again W 4 form for 2020 has definitely changed and Once again the employer hasto tell the employee by February 15 of 2020that’s not the employees fault or responsibility I think your word usage to answering questions is very disrespectful
