Germany’s income tax system has mandatory and voluntary filing. Many expats are unaware they can get significant refunds, or that they are required to file. Here is the essential guide.
Who Must File
You must file a tax return (Steuererklärung) if: you have income from multiple employers simultaneously; you received Kurzarbeitergeld (short-time work allowance), Elterngeld (parental benefit), Krankengeld (sick pay), or unemployment benefits above €410 in the year; you have income from self-employment or freelance work; your spouse is in a different tax class (Steuerklasse) combination; or you have received any income from outside Germany. If you are a standard employee with one employer, taxes withheld at source, and no special circumstances, filing is voluntary — but often financially beneficial.
Why Voluntary Filers Usually Get Refunds
Germany’s PAYE (pay-as-you-earn) system withholds income tax from salaries based on general calculations. The actual tax due after allowances and deductions is often lower. Common deductions that reduce tax due: Werbungskosten (work-related expenses) — if your actual work expenses exceed the €1,230 standard deduction, you can claim transport costs to work (€0.30/km, called Pendlerpauschale), home office (€6/day in 2024, up to €1,260/year), and professional equipment purchases; Sonderausgaben (special expenses) — donations to registered charities, church tax paid, pension contributions above employer deductions; haushaltsnahe Dienstleistungen — cleaning services, gardening, domestic help (20% of costs up to €4,000/year). Average German tax refund is around €1,027/year.
The Filing Process
Software options: ELSTER (free, the official German tax authority system — functional but not user-friendly); Taxfix (€34.99 flat fee, app-based, good for standard situations); Wundertax (€29.99, English-language option available); steuergo (€29.99, good for freelancers); or a Steuerberater (tax advisor, €150–500+, recommended for complex situations including self-employment income, foreign income, or rental property). Deadline: 31 July of the following year (e.g., 2024 taxes due 31 July 2025) if you file yourself; 28/29 February of the year after that if a Steuerberater files for you. For older unfiled years: you can file up to 4 years back (voluntary filing) and still receive refunds.
The Expat-Specific Issues
Foreign income: if you earned income abroad and in Germany in the same year, the foreign income typically affects your tax rate in Germany under the Progressionsvorbehalt (progression clause) — it is added to calculate your tax rate, then subtracted from the tax base. This almost always means a higher German tax rate applies to your German income. Double taxation treaties: Germany has comprehensive double taxation agreements with most countries. Which country has the right to tax which income depends on the treaty. For salary from employment: typically taxed in the country where the work is performed. Your Finanzamt (tax office) handles any double taxation relief. For significant foreign income (>€5,000), a Steuerberater is strongly recommended.
