German Steuerclass Guide: Types I–VI Explained

If you work in Germany, you've probably seen the term Steuerklasse on your payslip or employment contract. It's one of the most misunderstood aspects of German income tax; many employees think their tax class determines their total annual tax bill. In reality, it only affects monthly withholding. Your actual annual tax liability is reconciled when you file your Steuererklärung.

What is Steuerklasse?

Steuerklasse (tax class) is a classification system used by German employers to calculate monthly income tax withholding. It's based on your marital status and employment situation, not a choice you can freely make. The Finanzamt (tax office) assigns your class, and your employer uses it to withhold the correct amount from your monthly salary.

There are six tax classes:

Class I (Steuerklasse I): Single employees

This is the most common class, assigned to single, divorced, or widowed employees with no children. Class I offers no special allowances; you get the standard tax-free threshold (Grundfreibetrag) of €12,348/year (2026).

Who it applies to: Single employees, divorced persons, widowed persons

Class II (Steuerklasse II): Single parents

Single parents with at least one child get Class II, which provides a higher tax-free allowance (Grundfreibetrag plus Entlastungsbetrag für Alleinerziehende of €4,260/year). This results in lower monthly withholding compared to Class I.

Who it applies to: Single parents claiming child allowance (Kindergeld)

Class III (Steuerklasse III): Married, higher earner

If you're married and earn significantly more than your spouse, Class III gives the highest tax-free allowance and lowest withholding. Your spouse must be in Class V. This class is strategically used by couples with unequal incomes.

Who it applies to: Married employees who are the higher earner

Typical monthly saving: €100–400 more take-home vs. Class IV

Class IV (Steuerklasse IV): Married, equal earners

If both spouses earn similar amounts, Class IV is the default. Both partners get the same withholding, roughly equivalent to two Class I employees. It's the most straightforward for couples with balanced incomes.

Who it applies to: Married couples with equal or similar incomes

Class V (Steuerklasse V): Married, lower earner

The spouse in Class V (typically the lower earner) receives minimal allowances and pays a higher effective withholding rate. This is strategically paired with Class III to maximize take-home for the higher earner.

Who it applies to: Married employees who are the lower earner

Class VI (Steuerklasse VI): Second job

If you have a second (or third, fourth...) job, you must use Class VI for all jobs beyond the first. Class VI gets no tax-free allowance; all income is taxed at the progressive rate, with no credits. This is intentionally harsh to discourage side gigs.

Who it applies to: Employees with more than one job

How Steuerklasse affects your payslip

Your tax class directly impacts your Lohnsteuer (withheld income tax) on your monthly payslip. For example, two unmarried employees earning €50,000/year will have identical annual tax liability, but if one is Class I and the other is Class VI, their monthly withholding differs dramatically:

Scenario	Monthly gross	Approx. tax withheld	Monthly net
Class I (single)	€4,167	€600	€3,100
Class VI (second job)	€4,167	€900	€2,800

The Class VI employee takes home €300 less per month, but they'll receive a refund of roughly €3,600 when they file their Steuererklärung at year-end, because their actual annual tax is the same as the Class I employee.

When can you change your Steuerklasse?

Changes happen automatically:

• Marriage → move to Class III/IV/V
• Divorce → return to Class I or II (if you have children)
• Death of spouse → Class I or II
• Birth of child → Class II (single) or adjustment in Class III/V (married)

You can request a manual change:

You can request a Steuerklassenwechsel (tax class change) mid-year by filing Form U1 with your employer and the Finanzamt. Common reasons:

• Your spouse took a second job (move one partner to Class VI)
• You want to optimize withholding before year-end
• You're starting a side hustle (add Class VI)

Changes typically take effect the month after you file the form. There's no cost, and you can make one change per calendar year without special permission.

Does Steuerklasse matter for annual tax?

Short answer: No.

Your Steuerklasse only affects monthly withholding. Your actual annual income tax liability is calculated the same way regardless of class. When you file your Steuererklärung, the Finanzamt:

1. Calculates your true tax based on your total annual income
2. Subtracts all withholdings made during the year (across all classes/jobs)
3. Refunds the difference if you overpaid, or you owe if you underpaid

This is why Class VI employees (who have high monthly withholding) typically receive large refunds; they've overpaid throughout the year due to the harsh tax class, and the Finanzamt corrects it.

Tax class strategies for couples

Married couples can strategically use Classes III and V to optimize monthly cash flow. For example:

• Salary split 60/40: The 60% earner uses Class III (lower withholding), the 40% earner uses Class V (higher withholding). At year-end, both owe the same total tax as if they were both Class IV, but cash flow during the year favors the higher earner.
• One-income household: Working spouse in Class III, non-working spouse in Class IV (receives no income but is still assigned a class). This is slightly more favorable than both being Class IV.
• Both have Class VI jobs: Keep your primary job in Class III/V and add Class VI for the side gig. At year-end, the Class VI withholding is usually excessive and you get a refund.

Key takeaways

• Your tax class is mostly assigned by the Finanzamt based on your status, not chosen by you.
• It only affects monthly withholding, not your total annual tax.
• Married couples can use Classes III/V strategically to increase monthly take-home, but they owe the same amount annually.
• Class VI (second job) has high withholding but you'll likely get a refund.
• You can change classes once per year mid-year via Form U1.
• Always file a Steuererklärung; most Germans get a refund of €500–€2,000.
