        Working on the side in Belgium

        What to check before you take a task next to a full-time job. Orientation only; none of it is legal or tax advice.

        Before you start
        • Read the outside-work and conflict-of-interest clauses in your employment contract.
        • Check for a non-compete or a duty to disclose side income to your employer.
        • As a contractor you are usually responsible for your own income tax and social contributions; a local accountant can size the amounts.

        Your recruiter walks through these points with you before you accept a task. Read the guides
