Personal Income Tax: Marginal rates and social security contributions (Edition 2018)

This dataset reports marginal personal income tax and social security contribution rates for a single person without dependent, at various multiples (67%, 100%, 133%, 167%) of the AW/APW. The average wage (AW) is based on a single person at 100% of average earnings, no child. The results use tax rates applicable to the tax year. The results take into account basic/standard income tax allowances and tax credits and include family cash transfers. The marginal rates are expressed as a percentage of gross wage earnings, with the exception of the Total tax wedge which is expressed as a percentage of gross labour costs (gross wages + employer SSC).
