Best Tax Software for Expats in Germany [2026]

File your German tax return in English and get your refund. We compared the top tax tools for expats.

Filing a German tax return (Steuererklarung) is not mandatory for most employed expats, but it almost always makes sense. The average refund is over 1,000 EUR, and for expats who moved to Germany mid-year or have deductions like a home office, the refund can be significantly higher.

The problem: German tax forms are complex and mostly in German. That is where English-language tax software comes in. All three tools below let you complete your return in English through a guided step-by-step process, no Steuerberater (tax advisor) needed for standard cases.

How We Compared Them

We tested each tool with a standard employed expat scenario: single, Tax Class I, one employer, some work expenses. We looked at English language support, ease of use, price, and the types of deductions each tool catches. Wundertax takes our top spot for its combination of a clean English interface and thorough deduction guidance, but Taxfix's mobile-first approach is a close second if you prefer doing everything on your phone.

Pro Tip: You have until July 31 of the following year to file voluntarily (September 30 if you use a Steuerberater). If you are filing for previous years, you can go back up to 4 years. Many expats file their first return for multiple years at once and get a combined refund of 3,000-5,000 EUR.
