Do expats in Germany need to file a tax return for 2025?

Short answer: Most expats in Germany need to file a tax return if they earned income, worked as a freelancer, or want to claim deductions. Deadlines, documents, and eligible expenses vary, so prepare early and don’t leave money on the table.

For the 2025 tax year, most employees aren’t legally required to file unless you changed jobs, received benefits, or earned additional income. But filing is often worth it: many expats are eligible for refunds due to deductible relocation costs, home-office expenses, or pension contributions.

If you're self-employed, rented out property, or received income from abroad, filing is mandatory. The deadline is July 31, 2026 if you file on your own or February 28, 2027 with a tax advisor.

To file, you’ll need your Lohnsteuerbescheinigung (annual income statement), proof of deductible expenses, your tax ID, and bank details. For cross-border situations, foreign income documents may also be required.

Key takeaways:

• Most expats benefit from filing even when not required.
• Use a tax advisor to extend your deadline and avoid errors.
• Common deductions: relocation, pension, home office, tax advice.
• Prepare your documents early to avoid delays.
