Side income as an employee
Dear tax experts,
As an employee, I have a mandatory, non-self-employed main job. I am currently considering supplementing my income by doing additional work at events in the canteen occasionally rented to private individuals by the employer, as a supervisor/caretaker.
The employer would bill the tenant for the use of the space, but does not want to have anything to do with the supervisory staff. It is a marginally paid job, but a mini-job solution unfortunately would not be possible for the above-mentioned reason.
For my work, the tenant would pay me directly (on average around 100 € - 150 € per month) and I would have to consider this income in my income tax return at the end of the year. However, if the additional income is added to our family income, I assume the effort may not be worthwhile due to the tax burden.
My question:
Would it be possible in this case to reduce the tax burden (e.g. by registering as a business/freelancer or applying a separate, lower tax rate only for this marginal secondary job, disconnected from our family income)?
THANK YOU VERY MUCH
