What is important for a small business?

What is important for a small business, here is some information about me.

I'm currently still living at home because I'm in an apprenticeship, of course I will finish it and continue to work in my job. I'm currently 18 years old. I want to register a small business because of YT and Twitch because I can generate income there as well as small sponsorships. What is important?

The most important thing is that you have an idea of what you are doing or saying. Otherwise it won't work.

So I've been doing this for 4 years and take it professionally.

What is important?

That you can't register a small business.

Because neither the trade nor the tax law know a small business.

What you mean: Register a business and use the small business regulation according to § 19 UstG.

But that only applies to sales tax.

This means: up to an annual turnover (not profit) of 22,000e you will not be charged any VAT.

You are not allowed to offset the VAT you have spent with the FA and you are not allowed to show the VAT separately on your invoices.

All other types of taxes and duties remain unaffected by this regulation.

Your trusted tax advisor will explain everything else to you in detail.
