The difference among being an employee, freelancer, and self-employed in Denmark lies in the legal status, taxation, and employment arrangements. Employees work under an employment contract with an employer, enjoy social benefits, and have taxes withheld by their employer. Freelancers typically work independently on short-term projects, have more flexibility but are responsible for their own taxes and social benefits. Self-employed individuals run their own businesses, have full control but also full responsibility for taxes, benefits, and legal compliance, often requiring registration as a company.
