I just got a freelancing job in the Netherlands for 6 months and I really want to know what should I do to make sure I pay taxes and do this employment legally.

I currently live in Germany as a student and I hold German citizenship. The freelance job requires me to go only once a month for 4-5 days to the office.

The company is a tech company and I would be doing some tech + marketing job.

Do I need to pay taxes in Germany or in the Netherlands? Can I start working right now, or do I need to do some paperwork? I will be paid 32 per hour 8 hours a week. Is that enough to cover my expenses as a freelancer? How much tax would I have to pay?

If I registering in Germany, what are the steps to start freelancing right away?

If anybody can guide me, tell me what are my best options or any info at all it would be highly appreciated. Please let me know if you need more information about my situation.

Thanks in advance
