Since September 2015, students in the Netherlands who have their own business are allowed to earn unlimited income. Since September 2015 the basic student grant has been abolished. Instead, students can apply for a loan. However, these changes do not apply to students in secondary vocational education (Middelbaar Beroepsonderwijs, MBO).
Old student finance system
Students in the Netherlands who have their own business and receive student finance based on the student finance system before September 2015, may receive reduced study grants and loans, depending on their earnings. If your total (business) income does not exceed a limit, your student grants and loans may only be partly reduced. If you are running your own business during the last year of your study programme, you may keep the profits in full after having graduated.
