Tax deductible laptop for school?

My wife is in training and has tax class 5.
Since they only have online lessons at the moment, we need a new laptop.

Can you deduct the costs for this in the tax return?

Mostly she only needs it for school.

You can try, but the tax offices are very critical when it comes to recognizing the expenses for PC or laptops as advertising expenses.

Certainly it works. You can find more details here: https://www.steuertipps.de/die-erste-steuererklaerung/azubis/diese-kosten-sparen-steuern
