German tax classes (Steuerklassen) are part of the payroll tax system (Lohnsteuerabzug). They determine how much income tax (Lohnsteuer) German employers withhold from employees’ salaries. Understanding how German income tax classes work is one of the tax-related hurdles many expats face when working in Germany as an employee. Your Steuerklasse determines how much income tax is withheld from your monthly salary, which directly affects your take-home pay. It’s important to know which tax class applies to you and when it makes sense to change it. It is also important to understand that choosing the wrong tax class has no impact on the overall tax burden, because after filing a tax declaration you will receive a tax refund if you overpaid taxes due to inadequate tax class selection.
In this guide we explain all six tax classes, how they apply to different expat situations, and what choices you may have to optimize withholding tax while keeping your final year-end tax result unchanged. Also, we share first-hand insights based on Prinz.tax long-term experience serving expats in Germany.
What Are Tax Classes (Steuerklassen)?
In Germany, employers use your tax class to calculate how much income tax to withhold from your salary throughout the year. This withholding is not your final tax bill, which is determined later when you file your income tax return (Einkommensteuererklärung).
There are six tax classes (I to VI), and the one you fall into is based on your personal situation — most commonly your marital status, number of jobs, and dependents.
Tax classes affect monthly cash flow, not the total income tax due after your annual tax return. At the end of the year, the actual tax liability is calculated based on your total income, allowances, deductions, and filing status.
Tax Class I: Most Common for Single Expats
Who it applies to
- Single, divorced, widowed, or permanently separated individuals.
- Married expats whose spouse lives outside Germany.
- Expats who have just moved and have not yet updated their marital status with the Finanzamt (tax office).
Key points
- This is the default class for most new arrivals working in Germany.
- Your employer withholds income tax based on your salary and standard allowances.
- It offers the typical tax-free allowance used in wage tax withholding.
Tax Class II: For Single Parents with Relief
Who it applies to
- Single expats with at least one child living in the same household.
- You must be eligible for child benefit (Kindergeld) or a child allowance (Kinderfreibetrag) and not living in a multi-adult household context.
Why it matters
- This class gives extra relief in withholding compared to class I, recognizing the financial burden of raising a child.
- It reduces monthly tax withholdings for qualifying parents.
Tax Classes III & V: Married Couples With Different Incomes
These two classes work as a pair for married couples. One spouse chooses Class III and the other Class V.
Tax Class III (Lower Withholding)
- Tax class III should be used by the higherearning spouse.
- Offers a significantly lower withholding rate because it includes both partners’ basic tax allowances.
- Common when one spouse does not work or earns significantly less than the other.
Tax Class V (Higher Withholding)
- Assigned to the lowerearning spouse in a 3/5 combination.
- Withholdings under tax class V are higher, but the couple’s combined monthly net income is often higher.
- Important: Both spouses must be employees.
Prinz.tax practical tip: In our experience, some clients who have selected tax classes III and V are surprised to see an additional tax charge at year-end. This may catch you by surprise, but it happens a lot. Withholdings under tax class III and V represent only a rough estimate of the actual tax bill and upside or downside deviations are very common.
Tax Class IV: Married Couples With Similar Incomes
If both spouses earn similar salaries, tax class IV is usually the default choice.
Benefits
- Each spouse is taxed individually at a tax withholding rate similar to class I.
- It avoids the imbalance of the 3/5 combination when incomes are comparable.
- A factor option exists that fine-tunes withholding based on exact income ratios. In our experience, the factor option is too complex and is used very rarely.
Tax Class VI: For Second Jobs
When it applies
- You have more than one job with more than one employer.
- Your main job stays in your primary tax class (I, II, III, IV, or V), but each additional job is taxed in class VI.
Important notes
- Class VI has no basic tax-free allowance, and it results in higher withholding, making it costly as a second job.
Important Expat Considerations and Frequently Asked Questions
1. What are the most common tax class changes in Germany?
We often advise married couples switching between combinations (e.g., 4/4 ↔ 3/5), depending on their relative income. Another typical request is to change to tax class II to benefit from the “single parent” status. All changes require a formal request to your local Finanzamt.
2. What is the impact of my tax class on monthly net salary payments and total net income?
Choosing the right tax class can increase your monthly net salary payment, but it doesn’t change the total tax due for the year. The total net income after taxes for the tax year will be determined after filing your income tax declaration in Germany.
3. Does my tax class affect my final tax bill in Germany?
Your actual tax owed is determined when you file your annual tax declaration. You may receive a refund or even owe additional tax depending on allowances, deductions, and income sources. This will also fix any disadvantageous tax class during the year.
4. I recently arrived in Germany but was assigned tax class I even though I am married. How do I solve this?
It often takes several weeks until the tax office updates your profile which is electronically shared with your employer through the ELStAM process. In some cases, you may initially be subject to tax class I which is later updated to tax class III or IV. Contact your HR department to clarify the situation and get assistance.

Final Thoughts on Tax Classes for Expats
For expats in Germany, understanding Steuerklassen helps you manage monthly cash flow and avoid surprises when you file your taxes. While your final tax liability is determined by the annual return, the tax class you choose or are assigned affects how much tax comes out of your pay every month.
