Tax Class Switch for Married Couples (Steuerklasse III / V)
If one partner earns significantly more, switch from default Tax Class IV / IV to III / V to increase monthly take-home pay.
Configure your citizenship, housing, and job status to get a prioritized timeline.
Married couples automatically start in Tax Class IV / IV. If one partner earns 60% or more of the household income, staying in IV / IV means hundreds of extra euros are withheld from your salary each month until you file your annual tax return.

Submit an application to change tax classes ('Antrag auf Steuerklassenwechsel') via ELSTER or paper form to your Finanzamt.

Frequently Asked Questions
Which tax classes are assigned to married expats by default?[FAQ]
German authorities automatically assign Class IV / IV to both spouses upon registration. If incomes differ significantly (e.g. 60/40 ratio), switching to Class III / V increases immediate monthly take-home pay.
Does switching tax classes lower total annual income tax?[FAQ]
No. Annual tax liability is identical; Class III / V optimizes monthly net cash flow and creates a mandatory requirement to submit an annual tax return (Einkommensteuererklärung).
