Legal basis

Why is a tax-class change worth considering?

Elterngeld is calculated at 67 % of net income during the 12 months before the protection period (§ 2 BEEG). Holding class III instead of V during this time yields a higher net and therefore more Elterngeld — over 14 months of Basis, the difference can amount to several thousand euros.

Important: The change must be applied for at the latest 7 months before the protection period begins (§ 2c (3) BEEG). Later changes are not considered for the Elterngeld calculation.

— Recommendation

Empfehlung: Die elterngeldnehmende Person sollte in den 12 Monaten vor der Mutterschutzfrist Steuerklasse III führen. Der Wechsel muss spätestens 7 Monate vor Beginn der Schutzfrist beantragt werden (§ 2c Abs. 3 BEEG). Monatliche Mehrleistung: 360 €. Gesamt-Vorteil über 14 Monate Basis: 5040 €.

Monthly delta: 360 € · Total advantage 14 mo: 5,040 €

Note: Simplified net calculation (the Elterngeldstelle applies the BEEG § 2c lump sums exactly). Apply for tax-class change at the Finanzamt — at the latest 7 months before the protection period begins (§ 2c (3) BEEG). Not tax advice iSv § 2 StBerG.

FAQ — 08

Frequent questions about tax-class change

Q.01When do I need to switch tax class for it to count for Elterngeld?
The switch must be applied for at the Finanzamt at the latest 7 months before the maternity protection period begins (§ 2c (3) BEEG). Later changes are not considered.
Q.02Which tax class maximises Elterngeld?
The person taking parental leave should hold class III — it has the lowest income-tax deduction and thus the highest net. Since Elterngeld is 67 % of pre-birth net income, a higher net translates directly into a higher benefit.
Q.03What happens to taxes at year-end?
The tax-class choice only changes the monthly tax withholding, not the total tax burden. The annual tax return reconciles everything. But for Elterngeld only the monthly net during the 12 months before the protection period matters.
Q.04Is it worth switching even at equal income?
At nearly identical incomes (difference under ~10%), switching to III/V typically adds less than €30/month in Elterngeld. At IV/IV the administrative effort of applying and later reverting is rarely worthwhile.
Q.05Can I switch back to IV/IV after parental leave?
Yes. You can apply for a new switch at the Finanzamt at any time (§ 39 (6) EStG). Often III/V is kept throughout parental leave and the first months after return.
Q.06Does the switch affect Mutterschaftsgeld?
No. Mutterschaftsgeld is calculated on the last 3 months before birth (§ 24i SGB V). However, switching to class III in time also gives a slightly higher Mutterschaftsgeld base.
Q.07What is the Faktorverfahren for IV/IV?
The Faktorverfahren (§ 39f EStG) applies a calculated factor so tax withholding matches each partner's real income proportion. Elterngeld is generally lower for the leave-taker — because the class III advantage is absent.
Q.08Do I need my partner's consent for the switch?
Yes. Class changes to III/V or IV/IV with Faktor require both spouses to agree. The form "Antrag auf Steuerklassenwechsel bei Ehegatten" must be signed by both and submitted to the Finanzamt.
