The dutch goverment aims to make working more profitable. Starting in 2020 there will be only two tax rates on your income. The proposed tax rates for income from work (Box 1) will be lowered and limited to a base rate of 37.10% for income up to €68,507 and a top rate of 49.5% for income exceeding €68,507.
Further changes Box 1 – Deductions Certain deductible expenses will only be deductible against a maximum rate of 46% (instead of the top rate). These expenses concern: alimony payments, specific healthcare expenses, weekend expenditure for handicapped individuals, educational expenses, charity donations, self-employed deductions, the deduction for small and medium-sized enterprises and the exemption for the business use scheme.
