What is Steuerklasse and How Does It Affect Your Pay?
Germany's six tax classes determine your monthly withholding — not your annual tax rate. Here's which one applies to you and when to change it.

Steuerklasse is about withholding, not your tax rate
Steuerklasse (tax class) is one of the most misunderstood parts of the German tax system. Many people think it determines how much tax they owe — it doesn't. It determines how much tax is withheld from their monthly paycheck. Your actual annual tax liability is the same regardless of your Steuerklasse; the difference is settled when you file your annual tax return (Steuererklärung). Think of it as a pre-payment setting, not a tax rate.
This distinction matters because choosing the 'wrong' Steuerklasse doesn't cost you money in the long run — it just affects your monthly cash flow. A worker in Steuerklasse I who should be in III will have too much withheld each month but gets the excess back as a refund after filing. Still, most people prefer to keep more cash in hand each month, which is why choosing the right class matters for practical budgeting.
| Class | Who it's for | Allowances |
|---|---|---|
| I | Single, divorced, widowed (one job) | Standard (Grundfreibetrag €12,348) |
| II | Single parents (with child, living alone) | Standard + Entlastungsbetrag (€4,260+) |
| III | Married, higher earner (spouse on V) | Double allowance, lowest withholding |
| IV | Married, both working, similar income | Standard each |
| V | Married, lower earner (spouse on III) | No allowance, highest withholding |
| VI | Second or additional job | No allowance, highest withholding |
The six classes explained
Steuerklasse I is the default for single, divorced or widowed employees with one job. Steuerklasse II is for single parents who live alone with at least one child and qualify for the Entlastungsbetrag (currently €4,260 plus €240 for each additional child). Steuerklasse III is for married employees whose spouse earns significantly less or nothing — it gives the higher earner a larger tax-free allowance and lower withholding.
Steuerklasse IV is the default for married couples where both work and earn similar amounts — each gets their own standard allowance. Steuerklasse V pairs with III: the lower-earning spouse takes V (high withholding) while the higher earner takes III (low withholding). The combined annual tax is the same as IV/IV, but cash flow shifts toward the higher earner. Steuerklasse VI applies to second and additional jobs — no allowances, highest withholding.
Which combination should married couples choose?
The III/V split works best when one spouse earns at least 60% of the household income. The high earner in III sees dramatically lower monthly withholding, while the low earner in V has very high withholding — sometimes surprisingly so, making a part-time job feel barely worthwhile. The total annual tax is unchanged, but monthly cash flow concentrates in one paycheck.
The IV/IV combination suits couples with similar incomes. Since 2010, married couples can also choose IV with Faktor — a refinement where the Finanzamt calculates a factor that distributes withholding more proportionally, avoiding the large refund or payment that III/V can create. Our calculator models all three combinations so you can see which one suits your household's cash-flow preferences.
How to check and change your Steuerklasse
Your current Steuerklasse is stored in the ELStAM system (Elektronische Lohnsteuerabzugsmerkmale) and pulled automatically by your employer. You can check it on your payslip (look for 'Stkl' or 'Steuerklasse' near the top) or through your Elster account. If it's wrong — common after marriage, divorce, a spouse starting or stopping work, or moving to Germany — you can change it by filing a 'Steuerklassenwechsel' with your local Finanzamt.
Married couples can change their combination once per calendar year, or more often if there's a qualifying life event (birth, separation, job loss). The change takes effect the month after the Finanzamt processes it, usually within 2–4 weeks. If you've recently married and are still on Steuerklasse I, switching to III (or IV/IV with Faktor) can increase your monthly take-home by several hundred euros — use our calculator to see the exact difference before you file.
Common mistakes and how to avoid them
The most frequent mistake is staying on Steuerklasse I after getting married. Marriage doesn't automatically update your Steuerklasse — you must apply. Until you do, you're over-withholding every month, lending the government an interest-free loan. You'll get it back when you file, but why wait?
Another common error is a married couple defaulting to III/V when IV/IV with Faktor would suit them better. The V spouse often feels their job 'isn't worth it' because the withholding is so high — but that's an illusion created by the withholding split, not by actual tax owed. Understanding that Steuerklasse affects cash flow, not total tax, prevents this misperception from driving career decisions.

Frequently Asked Questions
+Does Steuerklasse affect how much tax I owe?
No. Steuerklasse only affects how much tax is withheld each month. Your actual annual tax liability is calculated the same way regardless of class — any over- or under-withholding is settled when you file your tax return.
+How do I change my Steuerklasse after marriage?
File a Steuerklassenwechsel with your local Finanzamt — you can do this in person, by post or through Elster. It typically takes 2–4 weeks. Married couples can switch once per year, or more often with a qualifying life event.
+Is Steuerklasse III always better for married couples?
Not always. III/V shifts cash flow to the higher earner but can make the V spouse's paycheck look disproportionately small. IV/IV with Faktor distributes withholding more evenly and avoids large year-end adjustments — it suits couples with similar incomes.
