Is it worth filing a tax return as a student?

I'm currently studying at a state university. I'm in the second semester and am aiming for a bachelor's degree. In addition to my studies, I work in a software company on a 450.00 basis. Now I have noticed that you can deduct tuition fees, travel costs, moving costs, costs for aids such as laptops, tablets, books, etc. From your tax during your studies.

What exactly does that mean for me and do you have experience how to approach the whole thing and whether that is even true?

I look forward to your useful comments.

It's worth it if you're paying taxes.

SAVING taxes can only be achieved if you also pay taxes.

You can only deduct something if you have paid wage tax, for example through a job, otherwise you can't deduct anything and the move should not be part of it!

Everything else actually belongs to the advertising package! But you should have receipts for everything you want to probably get more than 1000 euro back and you have to present everything!

But you can only get back what you paid in!

An income tax declaration could be worthwhile for two reasons.

Either if you have paid taxes on other income at all. Only then can stand payments be made for 2020.

Or if it is a second training. Then the study costs represent advertising costs. The loss (due to a lack of income) is then carried forward and offset later if you had to pay income tax.

But if you have no other income that is just special expenses, they don't affect you.
