What are the differences?
Price and joint filing
The biggest difference is right there in the price list.
€19 one-time per tax year, and joint filing is included in the price. You pay only when you file: fill in, review the result, then decide.
wundertax
wundertax costs €34.99 per return, and joint filing €49.99. If you file several years at once, packs bring the price under €30 per return. For a couple the gap stays largest: €49.99 against €19 at Norman (as of August 2026).
Filing through AI: Claude and ChatGPT
The complete return also works from Claude or ChatGPT: answer the questions, upload receipts, file. Norman submits to the tax office without you needing an ELSTER account. In the app, the same question flow guides you in German, English, or Russian.
wundertax
wundertax is a guided web flow in the browser, clearly structured and also available in English. Filing through an AI assistant like Claude or ChatGPT is not something wundertax offers.
Who it covers
Employees and private individuals (€19 one-time), self-employed people and freelancers with ongoing bookkeeping, and companies: including UG and GmbH with corporate tax and DATEV export.
wundertax
wundertax offers profession-specific flows for students, police officers, expats, and more: questions tailored to each case, which is a real strength. wundertax is not built for companies like a UG or GmbH.
What happens around the return
For the self-employed, Norman is more than the return: invoicing, receipt capture, and bank matching are free, the EÜR builds from ongoing bookkeeping, and VAT returns go directly to the tax office during the year.
wundertax
wundertax focuses on the tax return itself. Bookkeeping, invoicing, or a bank connection are not part of the product: you bring your figures ready-made.

Which Norman workflows are relevant here?

Do I still need a tax advisor?
