What is the job title?
I'd like to earn a little extra money alongside my full-time job (as a retail saleswoman). I'd like to pull weeds and mow the lawn, or just pull weeds. Since I don't want to get into trouble with illegal work, I'd like to register somehow. I'd also like to do a part-time job. The problem is: the hours from my main job overlap too often, meaning I can't make the part-time hours for my part-time job, and I work three different shifts. Would that then be considered unskilled gardening? Or would I be self-employed?
First of all, you could get problems if the maximum permissible working time is exceeded according to the working time law.

Then you should inform your main employee. Whether it is in need of tuning, I would have to research but he should know
You can register a trade office with relatively low costs (20-50€). They also tell you how the exact profession would be.
After registration, you will receive a tax number from the FA. You then have to enter the income in your tax return.
The health insurance is also informed – usually the contributions you pay are the same, except for very high incomes with your self-employment, then you would have to pay higher amounts.
You must also register with the relevant professional association, which would then be the “social insurance for agriculture, forestry and horticulture”. But they will explain everything to you in the business registration.
In addition, it is important that you make an invoice for each customer and keep a duplicate of it. All revenues and expenses you make for your independence are documented.
