It is a great and very easy to file tax with Wiso
★★★★☆Bahram Moradi· Aug 2, 2026
Easy to work with. It would be great if they could prepare some materials in English too. A bit pricey but it's ok. It would be awesome if they would offer plan for students with discounts.
★☆☆☆☆Sepehr Asgari· Jul 2, 2026
I used it based on the people's recommendation, and I submitted my tax for 2024. I bought a laptop as a student with a normal student job. Its tax was about €200, but I got €0 back in total. My tax is probably one of the easiest and cleanest cases, but I got nothing back. I am wondering if all these rates are true?!

They don't warn you about your subscription to renew, then pretend they send an email (as is required by German law). When you ask for them to prove it by forwarding said email, suddenly it wasn't possible. 0/10 Customer Experience. App isn't even that great for niche cases either.

They didn't send my declaration and charged me the annual fee twice 1 month. Be careful with them.
