An SME in another country has offered to hire me to do a specific programming task for them. Since 95% of you have frontend, backend or fullstack in your job titles, I thought someone here might have some advice…
How should one go about this in Switzerland - i.e., do I need a business number or anything?
Do I need to charge VAT?
How would I go about declaring this income (am taxed at source on permit B here)?
Keep in mind, this is a very small job, <20hrs, and I have no plans to evolve this into a significant source of income.
