Q: How does the German tax system work for expats?

A complete overview of how taxes work in Germany for expats, including income tax rates, tax classes, social security contributions, and filing requirements.

Germany’s tax system can feel complex, but understanding the basics will help you avoid surprises and even save money.
As an expat, your tax situation depends on your residence status, income type, and tax class.

Quick Answer

If you live in Germany for more than 183 days in a year or have your main home here, you’re considered a tax resident and must pay tax on your worldwide income.
Germany uses a progressive tax rate : the more you earn, the higher your tax rate : plus social security contributions and possible extras like church tax.

1. Who Has to Pay Tax in Germany?

Tax Resident (most expats working full-time):

Tax on worldwide income
Access to deductions and allowances

Non-Resident (short-term contract or remote worker abroad):

Tax only on German-sourced income

💡 Example: If you move to Germany in June and stay for more than 183 days, you’re a tax resident for that year.

2. Income Tax Rates for 2025

Germany’s rates are progressive:

Up to €12,084: 0% (tax-free allowance / Grundfreibetrag, 2025 value)
€12,085–€68,429: 14%–42% (gradually increasing)
€68,430–€277,825: 42%
Over €277,825: 45% (“rich tax” / Reichensteuer)

Plus:

Solidarity surcharge (Solidaritätszuschlag): 5.5% of income tax (mostly abolished for low/mid earners)
Church tax (Kirchensteuer): 8% or 9% of income tax if registered with a church

3. Tax Classes (Steuerklassen)

Your Steuerklasse determines how much tax your employer withholds:

Class I: Single
Class II: Single parent
Class III: Married, partner in Class V (higher earner here)
Class IV: Married, equal earners
Class V: Married, partner in Class III (lower earner here)
Class VI: Second job

📌 Tip: Married expats can often save money by adjusting tax classes : worth checking with a tax advisor.

On top of income tax, both you and your employer pay into:

Pension insurance (Rentenversicherung) ~18.6% (split 50/50)
Health insurance (Krankenversicherung) ~14.6% + Zusatzbeitrag averaging ~2.5% in 2025 (varies by insurer)
Unemployment insurance (Arbeitslosenversicherung) ~2.6%
Long-term care insurance (Pflegeversicherung) 3.6% with children / 4.2% if childless (rates effective July 2023)

💡 These contributions are tax-deductible to a large extent.

5. Filing a Tax Return

Mandatory for:

Self-employed
Multiple income sources
Married couples with certain tax class combinations
Claiming deductions

Deadline:

Without tax advisor: July 31 (following year)
