Germany Tax Return Guide (Steuererklärung 2026)
The Steuererklärung (German tax return) is due 31 July 2026 for the 2025 tax year (2 September 2026 with a tax advisor). Filing is mandatory if you were in class III/V, had multiple employers, received Kurzarbeitergeld, or earned self-employment income. Voluntary filing is recommended for employees — most receive a refund averaging €1,000+.
Germany's tax return system is increasingly digital through ELSTER (Elektronische Steuererklärung), the free government portal. Most taxpayers use ELSTER Online, commercial software (WISO Steuer, Taxfix, SteuerGo), or a tax advisor (Steuerberater). The process involves reporting your income, claiming deductions, and receiving either a refund (Steuererstattung) or a bill (Steuernachzahlung). For related reading, see our Personal Income Tax Guide → and Tax Classes Guide →.
Who Must File in 2026 (Mandatory Filing)
- Combination III/V: Married couples where one spouse is in class III and the other in class V must file a return. The monthly withholding in these classes does not match the final tax liability, so a true-up is required.
- Multiple employers: If you had income from two or more employers simultaneously (class VI for the second job), you must file. The Finanzamt needs to reconcile progressive rates across all jobs.
- Kurzarbeitergeld (short-time work benefits): Recipients of Kurzarbeitergeld, Krankengeld, Insolvenzgeld, or Mutterschaftsgeld above €410 must file because these benefits are subject to the Progressionsvorbehalt (progression proviso) — they increase the tax rate applied to your other income.
- Self-employment or business income: Any freelancer (Freiberufler) or business owner (Gewerbetreibender) must file annually. The deadline is 31 July (or 2 September with a Steuerberater).
- Rental income over €410: If you earned more than €410 from Vermietung und Verpachtung (rental and leasing), you must file an Anlage V with your return.
Seven Key Deductions for Employees
- Werbungskosten (work expenses): The €1,230 Pauschbetrag is automatic, but itemising often yields more. Commuting (€0.30/km), home office (€6/day up to 210 days), professional literature, and work equipment are all deductible.
- Home office (häusliches Arbeitszimmer): If your home office is the centre of your work, deduct actual costs (rent, utilities, internet). The simplified option: €6 per day (max 210 days = €1,260) without detailed proof.
- Double household (doppelte Haushaltsführung): If you work away from your main residence, deduct rent for a second home, one round trip per week (€0.30/km), and meals (€8/€12 per day for the first three months).
- Special expenses (Sonderausgaben): Church tax, charitable donations, and certain insurance premiums. The Pauschbetrag is €36 (€72 joint).
- Childcare costs (Kinderbetreuungskosten): ⅔ of childcare costs up to €6,000 per child per year are deductible as Sonderausgaben. This applies to Kita, Tagesmutter, and after-school care.
- Handwerkerleistungen (craftsman services): 20% of labour costs for renovations, repairs, and maintenance in your home, up to €1,200 per year. This includes plumber, electrician, painter, and gardener labour.
- Außergewöhnliche Belastungen (extraordinary burdens): Medical expenses, disability costs, funeral costs, and other unavoidable expenses. Deductible to the extent they exceed the "zumutbare Belastung" (reasonable burden), which is 1%–7% of income depending on your situation.
