Light entrepreneurship means self-employment without owning a business.
A light entrepreneur is someone who invoices the work they do through an invoicing service. A light entrepreneur decides what they do, who they work for and what they charge for it. In that sense, they are like an entrepreneur.
However, like a self-employed person, the light entrepreneur does not have a Y-identity number. For tax and accounting purposes, they are like an employee. For example, they do not have to file their accounts or VAT returns like a self-employed person.
However, from the point of view of unemployment insurance and pension insurance, a light entrepreneur is a traditional entrepreneur and is therefore covered by the YEL insurance.
