Filing Your German Tax Return as an Expat (Steuererklaerung Guide 2026)

Do You Need to File a Tax Return in Germany?

Many expats assume their employer handles everything through payroll tax (Lohnsteuer). While your employer does withhold income tax monthly, filing a Steuererklaerung (tax return) is mandatory in several situations — and highly recommended even when it is not.

You MUST File If:

You had income from multiple employers in the same year

You received unemployment benefits (Arbeitslosengeld), parental allowance (Elterngeld), or sick pay (Krankengeld) exceeding EUR 410

You and your spouse chose tax class III/V combination

You had freelance income (even a small side gig)

You received rental income or capital gains above the Sparerpauschbetrag (EUR 1,000 single / EUR 2,000 married)

The Finanzamt (tax office) sent you a letter requesting one

You SHOULD File If:

You are an employee in tax class I — the average refund is EUR 1,072

You had work-related expenses above EUR 1,230 (the Werbungskosten-Pauschbetrag)

You moved to Germany mid-year (you only owe tax on German-sourced income)

You paid for professional development, language courses, or commuting

Key Deadlines for 2026

Self-filing deadline: July 31, 2027 (for the 2026 tax year)

With a Steuerberater: February 28, 2028 (extended deadline)

Voluntary filing: Up to 4 years retroactively — you can still file for 2022-2025

The Key Forms You Need

Mantelbogen (Main Form)

Your personal details, bank account for refund, marital status, and religion (for Kirchensteuer).

Anlage N (Employment Income)

This is where most expats spend their time. It covers:

Gross salary: Pre-filled if you use ELSTER with your employer's electronic data

Werbungskosten (work-related expenses):

- Commuting allowance (Entfernungspauschale): EUR 0.30/km for the first 20 km, EUR 0.38/km beyond that - Home office deduction: EUR 6/day, max EUR 1,260/year (210 days) - Work equipment (laptop, monitor, desk) — items under EUR 800 net can be deducted immediately - Professional development, language courses, trade union dues - Work-related travel expenses - Job application costs (photos, postage, travel to interviews) - Double household costs (doppelte Haushaltsfuehrung) if you maintain a second home for work

Anlage Vorsorgeaufwand (Insurance Contributions)

Your health insurance, pension, and other social security contributions. The Krankenkasse sends you a Beitragsbestätigung with the exact figures.

Anlage AUS (Foreign Income)

If you have income from abroad (rental property, investments, pensions from your home country), report it here. Germany uses the world income principle — all global income is relevant, even if not taxed in Germany (it may affect your tax rate through Progressionsvorbehalt).

Anlage Kind (Children)

For Kindergeld, childcare costs (up to EUR 4,000/year per child), and school fees.

Deductions Expats Commonly Miss

1. Moving Costs (Umzugskosten)

If you moved to Germany for work, you can deduct:

Transport costs, temporary accommodation (up to 3 months)

Flat-rate allowance (Umzugskostenpauschale): EUR 886 for singles, EUR 1,772 for couples (2026 rates)

2. Language Courses

German language courses are deductible as Werbungskosten if your job requires German or if learning German improves your career prospects. Keep receipts and course certificates.

3. Double Household (Doppelte Haushaltsfuehrung)

If you maintain your primary household abroad and rent in Germany for work, you can deduct:

Full rent for your German apartment (up to EUR 1,000/month)

One trip home per week (Familienheimfahrt)

Meals during the first 3 months

4. Church Tax Opt-Out Savings

If you registered a religion at Anmeldung but do not actually belong to a German church, you may be paying 8-9% Kirchensteuer unnecessarily. You can leave the church (Kirchenaustritt) at your local Amtsgericht or Standesamt.
