German Tax Class Comparison 2026

The German Tax Class System: A Complete Guide for Expats

Germany's tax class system (Steuerklassen) is one of the most confusing aspects of the German tax system for newcomers. Unlike many countries where your tax situation is determined solely by your income and filing status, Germany assigns you a specific tax class that determines how much income tax is withheld from your monthly salary. There are six tax classes (Steuerklasse I through VI), each designed for a particular life situation.

For expats, understanding tax classes is essential because they directly impact your monthly take-home pay, sometimes by hundreds or even thousands of euros. The tax class you are assigned to (or choose, in the case of married couples) determines the monthly withholding amount that your employer deducts before transferring your net salary. While the annual tax liability is ultimately equalized through the income tax return, the monthly differences affect your cash flow, budget planning, and even your eligibility for certain benefits like parental leave allowance (Elterngeld) or unemployment benefits (Arbeitslosengeld).

Tax Class I – Single Employees (Steuerklasse I)

Tax Class I is the default class for all single employees, whether unmarried, divorced, or widowed (after the first calendar year following the spouse's death). If you arrive in Germany as a single expat, this is the class you will be assigned automatically when you register at your local tax office.

In Tax Class I, you receive the following allowances that reduce your taxable income:

• Basic tax-free allowance (Grundfreibetrag): €12,348 in 2026
• Employee expense flat rate (Arbeitnehmer-Pauschbetrag): €1,230
• Special expenses flat rate (Sonderausgaben-Pauschbetrag): €36
• Pension expense allowance (Vorsorgepauschale): Calculated based on your income

Tax Class I provides a fair balance between monthly withholding and annual tax liability. If you have no significant special circumstances, the monthly withholding amount is close to your actual annual tax obligation, meaning you will have neither a large refund nor a large additional payment when filing your tax return.

Tax Class II – Single Parents (Steuerklasse II)

Tax Class II is available exclusively to single parents who live alone with at least one child registered in their household. The key requirement is that no other adult is registered at the same address. This class provides an additional relief amount (Entlastungsbetrag) of €4,260 per year, plus €240 for each additional child beyond the first.

For expat single parents, this class offers meaningful tax savings compared to Tax Class I. At a gross salary of €4,000 per month, the difference can amount to €100 to €150 more net per month compared to Tax Class I. To claim Tax Class II, you need to submit an application (Antrag auf Lohnsteuerermäßigung) to your local Finanzamt and provide proof that you live alone with your child or children.

Tax Class III – Married, Higher Earner (Steuerklasse III)

Tax Class III offers the highest monthly net salary of all classes. It is available to married employees and registered civil partners when the other spouse takes Tax Class V. In Tax Class III, the double basic tax-free allowance (€24,696) is applied, dramatically reducing the monthly income tax withholding.

For expat couples where one partner works while the other is not yet employed (a common situation during the initial relocation period), the III/V combination can provide several hundred euros more net income per month compared to IV/IV. However, it is important to understand that the annual tax liability does not change – Tax Class III simply front-loads the splitting benefit into the monthly paycheck. You may need to file an annual tax return (which is mandatory for III/V) and could even face an additional tax payment if the withholding was too low.

Tax Class IV – Married, Equal Earners (Steuerklasse IV)

Tax Class IV is the default class for married couples and is calculated identically to Tax Class I. It is most suitable when both spouses earn similar incomes. The advantage of IV/IV is that the monthly withholding closely matches the annual tax liability, minimizing the risk of a surprise tax bill when filing.

Married couples can also opt for the factor method (Faktorverfahren), written as IV/IV mit Faktor. In this system, the expected income splitting benefit is already distributed between the monthly paychecks of both spouses. The factor is calculated by the Finanzamt based on both spouses' expected incomes. This provides more accurate monthly deductions and is generally the best option for couples with somewhat different but not vastly different incomes.

Tax Class V – Married, Lower Earner (Steuerklasse V)

Tax Class V is the counterpart to Tax Class III and provides no basic tax-free allowance in the monthly withholding. This results in a significantly lower net salary – income tax is calculated from the very first euro. Tax Class V is typically chosen by the lower-earning spouse in the III/V combination.

An important consideration for expats: if you are in Tax Class V and your spouse is in Tax Class III, the combined annual tax is the same as if you were both in IV/IV. However, the monthly distribution is very different. Tax Class V is particularly disadvantageous for calculating wage replacement benefits (Lohnersatzleistungen) such as parental leave pay (Elterngeld) or unemployment benefits (Arbeitslosengeld I), which are based on your net salary. If you plan to have children or anticipate a period of unemployment, switching to IV/IV before the relevant period begins is strongly advisable.

Tax Class VI – Second Job (Steuerklasse VI)

Anyone holding a second job alongside their main employment is automatically assigned Tax Class VI for the additional income. In this class, no tax-free allowances or flat-rate deductions are applied, meaning income tax is withheld from the very first euro at the full progressive rate. This results in the highest tax withholding of all classes.

For expats with side income (e.g., freelance consulting, teaching, or a part-time job), Tax Class VI can be a shock – the effective withholding rate is very high. However, the actual tax burden is determined through the annual income tax return, where all income streams are combined and taxed using the progressive tariff. Many employees in Tax Class VI receive a substantial refund after filing.

How to Choose the Right Tax Class as a Married Expat Couple

The choice between III/V and IV/IV (with or without factor) depends on your specific situation:

To change your tax class combination, submit the "Antrag auf Steuerklassenwechsel bei Ehegatten/Lebenspartnern" form to your local Finanzamt. Changes can be made multiple times per year since 2020. The change takes effect from the first of the month following the application (though some processing delay is common).

Tax Class Impact on Wage Replacement Benefits

Your tax class has a direct impact on several important wage replacement benefits, which are calculated based on your net salary:

• Parental Leave Pay (Elterngeld): 65% to 67% of net income, minimum €300, maximum €1,800 per month. Calculated from net salary in the 12 months before birth.
• Unemployment Benefits (Arbeitslosengeld I): 60% (67% with children) of net salary. Based on the last 12 months of employment.
• Short-Time Work Benefits (Kurzarbeitergeld): 60% (67% with children) of the net salary difference between full and reduced hours.
• Sickness Pay (Krankengeld): 70% of gross salary, capped at 90% of net salary, paid by health insurance after 6 weeks of illness.

The key takeaway for expats: if you or your spouse anticipate using any of these benefits, optimize your tax class in advance. The spouse who will receive the benefit should be in a class with a higher net salary (III rather than V).

Practical Example: Tax Class Impact on a €5,000 Gross Salary (2026)

To illustrate the dramatic differences between tax classes, here are approximate monthly figures for a gross salary of €5,000 in 2026 (no church tax, average health insurance surcharge, no children):

Note that the social insurance contributions are identical across all tax classes – only the tax amounts change. The difference between Tax Class III and Tax Class V at €5,000 gross is approximately €830 per month in net pay. For couples, this redistribution is intentional: the total tax for III+V combined equals IV+IV combined over the full year.

Planned Reform: Abolition of III/V

The German government has announced plans to abolish the Tax Class III/V combination in favor of the factor method (IV/IV mit Faktor) for all married couples. This reform is intended to make the monthly tax withholding more accurate and to address concerns that Tax Class V disproportionately reduces the net salary (and therefore wage replacement benefits) of the lower-earning spouse, who is statistically more often a woman.

As of 2026, both combinations remain available. When the reform takes effect, this calculator will be updated to reflect the new rules. In the meantime, the factor method is already available as a voluntary option and is generally recommended by tax advisors for its accuracy.

Tax Class Assignment for Special Situations

Newly Arrived Expats

When you first register in Germany and receive your tax identification number (Steuer-ID), you are automatically assigned Tax Class I (or IV if married). If your spouse is not yet in Germany, you may temporarily remain in Tax Class I until your spouse registers. Once both spouses are registered, you can apply for the III/V or IV/IV combination.

Cross-Border Commuters

If you live in a neighboring country (Austria, Switzerland, France, Netherlands, etc.) and commute to work in Germany, special rules apply under the respective double taxation agreement. You may be subject to limited tax liability (beschränkte Steuerpflicht), which restricts your tax class options and available deductions. EU/EEA nationals can apply for treatment as unlimited taxpayers if at least 90% of their income is earned in Germany.

Spouse Working Abroad

If your spouse lives with you in Germany but works abroad, the income from abroad affects the tax class choice. Under most DTAs, foreign employment income is exempt from German tax but subject to the progression clause (Progressionsvorbehalt), which increases the tax rate on your German income. Joint assessment and Tax Class III/V may still be beneficial – consult a tax advisor for your specific treaty situation.
