How to File Your German Tax Return as an Expat — Steuererklärung Guide 2026
Frequently Asked Questions
Do expats have to file a German tax return?
Not always. Many employees can file voluntarily, but you may be required to file if you had multiple employers, wage replacement benefits, foreign income, self-employment, certain spouse tax class combinations, or if the Finanzamt asks you to file.
What is the German tax return deadline in 2026?
For the 2025 tax year, the regular deadline for required self-filers is 31 July 2026. If a tax advisor or Lohnsteuerhilfeverein files for you, the deadline is usually extended.
Can I file my German tax return in English?
Yes, several tax apps such as Taxfix, Wundertax and SteuerGo offer English-language filing flows. ELSTER is the official free portal, but it is mostly German and less beginner-friendly.
What documents do I need for a German tax return?
You usually need your Steuer-ID, Lohnsteuerbescheinigung, IBAN, health insurance data, commuting details, home office days, and receipts for work-related or special expenses.
Should I use ELSTER, a tax app, or a Steuerberater?
Use ELSTER if you are comfortable with German tax forms, a tax app for straightforward employee cases, and a Steuerberater for foreign income, freelancing, rental income, stock options, or complex cross-border situations.
