German Tax Returns (Steuererklärung): The 2026 Expat Guide

The Expat Tax Reality

Oliver, 12 Years Financial Experience

"

"Every year, I see expats leave thousands of euros on the table simply because they are afraid of the German word Steuererklärung. They assume their employer has already paid everything perfectly. But your employer doesn't know that you spent €2,000 moving your family here, or that you bought a new laptop for your home office. The German tax system is actually incredibly generous with deductions (Werbungskosten)—but only if you ask for them. In 2026, with English tax apps, there is zero excuse not to file."

In Germany, taxes are collected at the source. If you are a standard employee (Tax Class 1 or 4), your employer calculates your income tax (Lohnsteuer), solidarity surcharge, and social security contributions, and deducts them automatically from your gross salary before your paycheck hits your bank account.

Because the system assumes a standard flat-rate deduction, the withholding is almost always overly conservative. The government essentially holds onto more of your money than necessary throughout the year. The only way to get it back is by filing a tax return.

1. Voluntary vs. Mandatory: Do you HAVE to file?

The first thing you must determine is whether you are legally required to file a tax return (Pflichtveranlagung), or if you are doing it purely voluntarily to get a refund (Antragsveranlagung).

Voluntary Filing (Most Single Employees)

If you are single, work a single job in Tax Class 1, and have no other sources of income, you generally do not have to file a tax return. It is purely voluntary. However, you absolutely should, because you are highly likely to get a refund.

Mandatory Filing (You MUST file if...)

The German tax office (Finanzamt) legally requires you to file a tax return if any of the following applied to you in the previous tax year:

2. The 2026 Filing Deadlines

Missing a mandatory deadline can be expensive. The Finanzamt can automatically assess your taxes, demand an arbitrary sum, and hit you with late fees (Verspätungszuschlag) of €25 for every month you are late.

If you are REQUIRED to file (Mandatory):

• Without a Tax Advisor: The deadline is July 31st of the following year. (e.g., Your 2025 tax return is due on July 31, 2026).
• With a Tax Advisor (Steuerberater) or Lohnsteuerhilfeverein: You get an automatic extension. The deadline is usually the end of February of the second following year.

If you are filing VOLUNTARILY:

• You have a massive four-year window to submit your return.
• For example, you can submit your voluntary 2022 tax return anytime until December 31, 2026. This is perfect for expats who want to file retroactively for their first year in Germany.

3. Top Expat Deductions (Werbungskosten)

If you are filing voluntarily, the goal is to lower your taxable income by declaring expenses you incurred to do your job. These are called Werbungskosten (Income-related expenses).

Every employee in Germany gets a flat-rate allowance (Arbeitnehmer-Pauschbetrag) of €1,230 automatically deducted from their taxable income. You only need to provide proof and file specific deductions if your actual expenses exceed this €1,230 threshold.

For expats, exceeding this threshold is very easy, especially in your first year.

A. Relocation Costs (Umzugskosten)

If you moved to Germany for a job, your relocation is considered a professional expense. You can deduct:

• Flights or train tickets to Germany for you and your family.
• Shipping containers or moving trucks for your belongings.
• Visa application fees.
• Temporary accommodation (e.g., Airbnb) while looking for a permanent apartment (up to 3 months).
• A "Relocation Flat Rate" (Umzugskostenpauschale) for miscellaneous unreceipted expenses (currently around €964 for singles).

B. The Home Office Flat Rate (Homeoffice-Pauschale)

Since the pandemic, Germany allows you to deduct €6 per day that you worked entirely from home, up to a maximum of 210 days per year (€1,260 maximum deduction). You do not need a dedicated, separate office room to claim this. Working from your kitchen table qualifies.

C. Commuting Allowance (Pendlerpauschale)

For the days you actually went to the office, you can deduct €0.30 per kilometer for the one-way distance between your home and your workplace (and €0.38/km from the 21st kilometer). It does not matter if you drove, took the train, or walked.

D. Double Household (Doppelte Haushaltsführung)

If you maintain a primary home (where your family lives) and rent a second apartment in Germany specifically for work, you can deduct the rent, utilities, and weekly flights back home. This is heavily scrutinized by the Finanzamt, so keep meticulous records.

E. Work Equipment & Education

• Laptops, monitors, office chairs, and desks used for work. (Items over €800 usually need to be depreciated over 3 years, but software and computers can often be written off in a single year).
• German language courses, provided they are demonstrably necessary for your job.

4. How to actually file your Tax Return

You have three main paths to file your Steuererklärung in Germany.

Next Steps

If you are a standard employee, the easiest way to stop procrastinating is to open a tab with an English tax software, enter your details from your annual payslip (Lohnsteuerbescheinigung), and see what your estimated refund is. It takes 15 minutes and costs nothing to check.
