| If you create a legal entitiy you will have to pay taxes / IHK (depending on your annual profit) and some tax consultant fees. But in my eyes the benefit overweights: - all your business expenses are kept in a professional setting and don't screw with your personal finances - you will have a separate bank account - you have a legal entity you can later sell to a real business - you can use leftover money to (re-)invest into nearby business areas - you have limited liability (and you can buy proper insurances for your risky business activities!!) Your local IHK will be happy to guide you through this process. I also started off as a sole proprietor and moved up the food chain through UG to GmbH(s), and there is so much you will learn during this process. I think every entrepreneur should have experience with local trade laws and taxes, so in my eyes you can't start early enough. If you have any questions feel free to ping me. |
Bank account: Just go to your bank and create business bank account.
Leftover money: It's up to you how much you withdraw, although you must pay tax on all income minus expenses.
Limited liability is not true (see Geschäftsführerhaftung).
Insurance: Again, you can get insurance (IT-Betriebshaftpflicht) as a sole proprietor too.
I think, if your project is merely ramen-profitable, don't bother about all the organizatorial overhead.
Another downside of a UG/GmbH: More paperwork for taxes etc. (double bookkeeping).
