Tax return from 2016-2018 + student?

Finally wanted to make my own tax return (s),

I have worked minijobmäßig in 2016/2017 and earned about 3k gross, since 2018 (summer) I'm working alongside the studies at the German Post and had on the employment tax statement about 4k gross. Now come to advertising costs as a student as laptop, printer purchased, semester fees, etc. Documents available.

with a lot can one calculate about what to recover or is there anything again?

For mini jobs, the employer usually pays the payroll tax. If that was the case then the income in the income tax return should not be taken into account.

since 2018 (summer) I work beside the studies at the German post office and had on the employment tax certificate about 4k gross.

If payroll tax has been withheld, it will be refunded in full, as the basic allowance of 8820 euro has not been exceeded.

In the current legal situation, expenses for a first degree course are not expenses, but special expenses.

Your annual tax burden will be reduced according to deductible expenses, of course, the basic requirement is that you have ever paid taxes to reduce these income tax return.

For this purpose, there are income tax assistance associations for persons who have little or no idea of the income tax return; Tax advice here in the community is unfortunately prohibited!

A tip wg. The mini-jobs: if your employer has paid the 2% flat-rate tax for you at the mini-job (can be seen from your payroll!), Then you do not have to specify these mini-jobs at all in your income tax return ;-)
