I applied individually before and i got very less tax and some times i used to pay back..
But this year i applied through wundertax and i got very good tax return within 4 weeks.
It's very simple to use, great cost/value ratio
It's very simple to use, it offers english language, the cost/value ratio is great. I have used for 3 or 4 years now.
Their support team is very helpful too, they don't answer in a generic manner but really personalised to your specific request.
I can only recommend it!
After 2 months of waiting tax office…
After 2 months of waiting tax office replied to me that my refund is 0 euro. I contacted the wundertax support team to get some help with it, because there was obviously a mistake. But unfortunately they did not want to reply, the only thing wundextax wants is to spam your email that they are solid, that there is friendly open-minded customer service, though it is nothing but a lie.

Easy and intuitive tool
Great tool, especially for non native speakers but also for those are not particularly accustomed to the intricacies of tax returns.
It is very intuitive and brings you step by step through the process.
I have used it already for a couple of years and would continue to do so.
If I have to find a flaw is that the estimation of the money return is most of the time incorrect, and also I would expand the function for the home office deduction. I had to present at a later stage many additional documents to the tax office.
Incorrect calculation, payment to Finanzamt required
I did two declarations with Wundertax, unfortunately the results provided by the tool were not inline with what Finanzamt has calculated. e.g. Wundertax has calculated a positive payment to me, but Finanzamt has requested me to pay them back an amount of €256,96.
I am very disappointed with the tool. My case is not a complicated one.
As mentioned I did two declarations, I am anxiously waiting for the feedback in regard to the second one.
This is not how such tools are supposed to work in my opinion.

Quick and easy tax return
As a foreigner, it was very easy to follow all steps to take for the tax return. I only submitted my information at the end of October for 2022, and I received my tax refund already 2 weeks later. Can recommend.
Really great service and easy to use…
Really great service and easy to use platform to help expats navigate a foreign tax system with ease. Very supportive team throughout the whole process. I have used Wundertax for the last five years and it’s always been a delight to use. Thanks for the great tool
It gives me very nice user experience
It gives me very nice user experience. I am also working in the software area. I think this software makes my life in Germany more easy!
It was fast and easy!
Seemless process
The tax form was easy to understand and complete. The whole process was seamless.The returns came earlier than stated by Wundertax. So impressed with the whole process, seeing it was my frist time filling tax returns. Definitely recommending Wundertax.
Simplified tax declaration
I had a great experience with Wundertax. In particular, I really liked the simplified interface and the broad range of expenses you could declare. Although there are minor bugs that should be fixed. But those bugs are not blocking and don’t have significant impact on the user experience. Highly recommended.
Recommended for the first time tax returns in Germany
I filled the Tax reimbursement form in Germany for the first time. My friend recommended me to use Wunder tax. I submitted the tax form a day before the deadline via Wunder tax. The procedure to fill the tax will the explanation is quite brilliant. I received my amount as expected :). Thank you. Cheers!
DE Tax Filing made easy for English speakers
Ease of filing tax returns, proactive follow-up information from Wundertax, easy on the fee, simplistic interface.
Nice articles and explanations available that can be used to understand different tax components.
Wundertax is incredibly user-friendly…
Wundertax is incredibly user-friendly and hassle-free. I got my tax refund in just 30-40 days, a significant improvement from my previous experience with Taxfix, which took a whopping 9 months for a much smaller refund. Wundertax not only ensured accuracy in my return amount but also simplified the process with easy-to-follow steps.
Hassle Free Experience
1. It was completely smooth experience.
2. Uncommon fields were hidden, available only when needed.
3. Very much satisfied
Self-explanatory English service
Self-explanatory, user friendly and easy to use.
Ideal for individuals with limited German language proficiency who are seeking tax filing services in English
Fast and easy to use!
