Annual income from labour consists of:
• gross wage from labour plus employer health care contribution minus social contributions
• gross profits self-employed plus contribution health care minus social contributions
• wage from labour abroad
• wage from other labour in 2004.

If a person had more than one source of income in 2004, all wages are added up to form the annual income.

For the calculation of a person’s annual income, the number of hours worked is irrelevant.
