I have a question and although I have a full time job and my wife is a student (no job) and in the tax return, I'm not sure if I should enter the things (contributions, travel costs, laptop, materials.) Of my wife and if so! Where should I enter it?
Ask a tax consultant or a Lohnsteuerhilfe- Verein.
That costs, but you will receive a competent answer.
Again a student who does not know where to find information and how to process it. Maybe you look at advertising costs and explanations
Yes, again such an answer
