German Tax Return (Steuererklärung): Do You Actually Need to File One?

If you're a standard employee with one job, no significant side income, and your tax gets withheld automatically each month via Lohnsteuer, you're often not required to file a Steuererklärung at all — the tax already deducted from your paycheck is treated as final. That said, "not required" doesn't mean "not worth it": many people who don't have to file end up getting money back if they do, since deductible expenses (commuting, work equipment, moving costs) usually aren't accounted for automatically.

You are required to file if any of the following apply: you have additional income beyond your main job worth more than €410 a year, you had multiple employers during the year, you and your spouse chose the tax class combination III/V, you received benefits like unemployment pay or short-time work allowance, or the Finanzamt directly asks you to. Freelancers and the self-employed almost always need to file, regardless of income level.

For 2026, the basic tax-free allowance (Grundfreibetrag) is €12,348 for a single person, doubled to €24,696 for married couples filing jointly — you pay no income tax at all on earnings up to that amount, and it's applied automatically by your employer's payroll and the Finanzamt, so you don't need to claim it separately.

Filing happens through ELSTER (Elektronische Steuererklärung), the Finanzamt's official online portal — free to use, though the interface is famously unfriendly to newcomers and entirely in German. Many expats use a tax software service (like Taxfix, Wundertax, or SteuerGo) or a Steuerberater (tax advisor) for their first filing, which costs money but avoids costly mistakes on unfamiliar forms.

The deadline for a voluntary return is generally three years after the tax year ends, so there's little urgency if you're filing to claim a refund. If you're required to file, the standard deadline is 31 July of the following year — or later if a Steuerberater files on your behalf, since tax advisors get an automatic extension.

Keep records as you go rather than scrambling at the deadline: commuting costs, home office expenses, professional training, and even costs directly tied to your move to Germany (flights, visa fees, relocation costs) can often be deducted, but only if you can actually document them.
