Progressive tax on wages etc. (box 1)
There is a
progressive tax on wages,
social security benefits and
pensions. Thus there are
tax brackets, each with its own
tax rate. Mathematically, apart from
discretization (whole euros both for income and for tax), the tax is a continuous,
convex,
piecewise linear function of income. For people above the pension age, the social security component is reduced. Additionally, there are income-dependent deductions and tax credits for incomes up to €90,710 which decrease the effective tax rate. Under certain conditions a
life annuity is treated as a pension: premiums are deducted from the income, the benefits are taxed, and the scheme is not counted as asset in box 3. The conditions concern the type of life annuity and the necessity, based on the principle that the higher the income is, the more pension plus life annuity one needs to build up for the future, up to a maximum. For the value of an owner-occupied dwelling and for
mortgage debt related to that, this box and not box 3 applies. Based on the value of the dwelling, a "fixed rentable value" is counted, while
interest for the mortgage is deductible. This is an important factor, since interest on a mortgage can easily be over a thousands euros per month, which is subtracted from income before any income tax is applied. If the value of an owner-occupied dwelling would be positive (fixed rentable value is greater than interest) it is changed to zero. For taxpayers above the official retirement age reduced rates apply for the first two brackets. In 2019, the corresponding tax rates are 18.75% and 20.20%. The discount of 17.9% of the income in these brackets corresponds to the
AOW contributions, which are not owed by the AOW beneficiaries. In 2018, the retirement age in the Netherlands was postponed from 65 years and 9 months to 66 years. For employed and self-employed people there is an employment rebate. The wage
withholding tax is a deduction of wages, social security benefits and pensions, as an advance payment for the income tax, paid through the employer, etc. See also

Health insurance premium From 2006 there is a new national
health insurance scheme (
zorgverzekering(swet),
Zvw). The premium is partly income-dependent and paid as a tax supplement. It applies for the "contribution income" (
bijdrage-inkomen), which is part of box 1, including labor income, social security benefits, pensions, and life annuities (it does not include the "owner-occupied dwelling income"). It is withheld if the wage withholding tax applies. The rate is 7.1% for e.g. wages and 5% for e.g. life annuities, coming on top of the tax percentages mentioned above. The total income for which these rates apply is limited to ca. 50,000 euro. ==Tax on income from a substantial business interest (box 2)==
