[All AI Evaluator: Tax rates by country](https://deftridge.com/jobs/ai-evaluator-tax/) ## Working on the side in Spain 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.
