German Tax Classes (Steuerklassen) Explained for Expats

What Are Steuerklassen?

Steuerklassen (tax classes) determine how much income tax is withheld from your monthly salary. They don’t change your total annual tax — just the monthly prepayment amount. After filing your annual return (Steuererklärung), you get money back or owe more.

The 6 Tax Classes

| Class | Who | Monthly Impact |
|-------|-----|----------------|
| I | Single, divorced, widowed | Standard deductions |
| II | Single parents | Higher deduction (Entlastungsbetrag) |
| III | Married (higher earner) | Much lower withholding |
| IV | Married (equal earners) | Same as Class I |
| V | Married (lower earner, paired with III) | Higher withholding |
| VI | Second job / additional employment | Highest withholding, no deductions |

Which Class Should You Choose?

If You’re Single - Class I — automatic, no choice needed - Class II — if you’re a single parent (apply at Finanzamt)

If You’re Married - Both earn similar amounts: IV/IV (default) - One earns significantly more: III/V (higher earner gets III, lower gets V) - Faktor method: IV/IV with Faktor — most accurate monthly withholding

The III/V Trap Class III/V means the lower earner has very high monthly withholding — often discouraging the lower-earning spouse (usually women) from working. Consider IV/IV with Faktor instead.

How to Change Your Tax Class

1. Fill out the Antrag auf Steuerklassenwechsel form
2. Both spouses must sign (for married couples)
3. Submit to your local Finanzamt
4. Changes take effect the following month
5. You can change tax classes once per year (plus on marriage/divorce/birth)

Impact on Other Benefits

Your tax class affects:
- Elterngeld — calculated based on net income, so Class III = higher Elterngeld
- ALG I (unemployment) — based on net income from your tax class
- Kurzarbeitergeld — short-time work compensation

Pro tip: If you’re planning to have a baby, switch to Class III at least 7 months before the expected Elterngeld period starts.

Common Expat Mistakes

• Not realizing you can change classes after marriage
• Assuming Class I is permanent (it changes automatically on marriage)
• Not filing a tax return when in Class III/V (it’s mandatory)
• Forgetting to update after divorce
