The German Steuererklärung (tax return) is not mandatory for most employees, but for anyone with deductible expenses, filing one almost always results in a refund. The average German tax refund is over €1,000 — and international workers often have deductible expenses many don’t know about.
The Arbeitnehmer-Pauschbetrag vs. Actual Deductions
The tax office automatically grants every employee a €1,230 Arbeitnehmer-Pauschbetrag (standard employee deduction). If your actual deductible work expenses exceed €1,230, filing a return and claiming actuals instead of the standard deduction is beneficial. Most people with a meaningful commute, home office days, professional development, or union membership exceed €1,230.
Key Deductible Categories for International Workers
Fahrtkosten (commuting costs): €0.30/km for each kilometer of the one-way distance to your workplace (using the Entfernungspauschale). For a 15km commute, this is €4.50/day × ~230 working days = €1,035 — already close to the standard deduction on its own. Public transport Jahrestickets: deductible if work-related.
Homeoffice/Arbeitszimmer: if you work from home, you can deduct €6/day for up to 210 days (€1,260 maximum in 2026) without requiring a dedicated home office room.
Weiterbildung (professional development): courses, certifications, books, and conferences directly related to your current job are deductible. Language courses (specifically German courses if you work in a German-language environment) are deductible. Non-work-related education is not.
Doppelte Haushaltsführung (dual household): if you maintain a household in another city or country and a work-related apartment in Germany, significant additional deductions apply. This applies to: people who moved to Germany for work while keeping their family home abroad, and people who work in one German city but commute from another.
Umzugskosten (relocation costs): if you moved to Germany (or within Germany) for a new job, relocation costs are often deductible. Requires that the move was primarily for work purposes.
Using AI for Steuererklärung Preparation
AI prompt: “I’m an international worker in Germany. My situation: [describe your work setup, commute, home office days, any courses taken, professional subscriptions]. What deductions can I claim in my Steuererklärung and approximately what amounts are we talking about?” This generates your personal deduction checklist. Then use ELSTER (German official tax software, free) or tax software like Wundertax, TaxFix, or Smartsteuer to file, using the AI-generated checklist to ensure you claim everything eligible.
