Working on the side in California

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
