How Steuerklasse III works in 2026
Steuerklasse III is chosen by the higher-earning spouse in a married couple or registered partnership, while the lower earner takes Steuerklasse V. Class III applies the splitting tariff — effectively double the basic allowance — so it withholds the least wage tax of any class and produces the highest monthly net for that salary.
When does III/V make sense?
The III/V combination works best when one spouse earns clearly more than the other (a rough rule of thumb is a 60/40 split or more uneven). The higher earner in Class III keeps more each month, while the lower earner in Class V bears a heavier monthly deduction. Compare it against IV/IV with our Steuerklassen-Kombination calculator.
Important: withholding only
Class III only changes how much is withheld during the year — it does not change your final tax. A married couple's actual liability is settled jointly in the annual tax return, so a large monthly III advantage can lead to a back-payment if the V spouse's income was higher than expected.
