Tax class
Select which tax class is specified on the employment tax statement. The entry of the tax class is for the tax office's control only and has no effect on the calculation of your income tax. The tax class only plays a role in calculating the monthly income tax that your employer pays to the tax office.
Have you changed your tax class in 2021?
If you have changed the tax class in the current year (e.g. marriage or divorce), enter here the last valid tax class (1 to 5).
You can only have tax class 6 if you have another employment contract (simultaneously with several employers).
Note: Information on the work-factor method for tax class 4 shall not be recorded. It is also not necessary to provide information on any allowances that the employer takes into account when preparing the monthly payroll.
