Tax Class Change for Married Couples

Easy ~8 min TaxMarriagePayroll

/ What is this form?

Married couples can choose between tax class combinations III/V or IV/IV. Changing classes doesn't affect total annual tax — only the monthly withholding. Since 2023, spouses can change multiple times per year.

Class III/V makes sense when one partner earns significantly more — the higher earner pays less monthly tax (class III) while the lower earner pays more (class V). The total annual tax is settled through the tax return.

The Faktorverfahren is a refined alternative where both partners are assigned class IV with an individual factor, achieving a more accurate monthly withholding and avoiding large refunds or back-payments.

Believing a tax class change reduces your total annual tax — it only changes monthly withholding.

Not considering the Faktorverfahren option for couples with similar incomes.

Choosing class V without understanding the high monthly withholding it causes.
