If you’re working or living in Germany, you’ve probably heard of the Einkommensteuererklärung — the German income tax return. But what exactly is it? Who is required to file it? And how do you know if you’re entitled to a tax refund?
In this guide, we’ll explain what the German income tax return is, who needs to submit it, and why it might be in your best interest to file one – even if you’re not obligated to.
What Is the Income Tax Return (Einkommensteuererklärung)?
In Germany, taxes are usually automatically deducted from your salary each month. However, at the end of the year, you can submit a tax return to let the tax office (Finanzamt) review your actual income and expenses.
This return:
- Helps determine whether you paid too much or too little tax
- Can lead to a refund or, in some cases, an additional payment
- Covers a full calendar year (January–December)
Who Is Required to File a Tax Return in Germany?
You are legally required to file a tax return if:
- You had multiple jobs or sources of income
- You received unemployment benefit (ALG I), parental allowance (Elterngeld), or other tax-free income above €410
- You are married and have tax class combination III/V or IV with factor
- You had freelance, self-employment, or rental income
- You received a pension above the taxable threshold
- You requested tax deductions in advance (e.g., for commuting or childcare)
Who Can File Voluntarily – And Why You Should
Even if you’re not required to file, it can still be very beneficial.
Voluntary filing is common if:
- You’re an employee with tax class I or IV and only one employer
- You had work-related expenses (commuting, home office, training, etc.)
- You paid for insurance, donations, medical bills, childcare
- You changed jobs or had income fluctuations
Many employees receive a refund of €1,000 or more – especially if they had deductions.
Bonus: You can submit voluntary tax returns up to 4 years after the end of the tax year.
