Work in NL, Second job
In the Netherlands, you are usually allowed to have a second job in addition to your main job. If you have a residence permit, however, your residence permit must clearly state that this is allowed.
Working for a second company
You are allowed to work for two employers at the same time in the Netherlands. In that case, we say you have a second job. You must always inform both employers about the other job. They need to know that you work somewhere else too. Sometimes your contract says you have to ask permission.
Self-employment alongside your job
You may also work as an independent contractor or self-employed person alongside your job. This means you work for yourself, for example as a painter or artist. You need to register with the Chamber of Commerce (KVK) . You also have to pay tax on your income. You arrange this through Belastingdienst.
