LOCAL GOVERNMENT INCOME TAX IMPLEMENTATION MODELS IN EUROPEAN COUNTRIES

The study summarises the experiences of Finland, Sweden, Denmark and Norway in introducing and implementing a local personal income tax. It answers 14 research questions and draws mainly on document analysis, complemented by input from external experts. 

We compared key indicators across the four countries, including the municipal income tax rate and effective tax rate, local tax revenue per capita, and residents’ average income. The report highlights the main strengths and weaknesses of each model and includes a comparative table of the countries’ local income tax systems. 

In all four countries, the local personal income tax is a major source of municipal revenue and plays an important role in financing welfare-state services. Equalisation systems are central to reducing disparities between municipalities. However, the countries differ in how much discretion municipalities have over tax policy: Sweden and Finland represent a high-autonomy model, Norway a strictly constrained model, and Denmark – despite formal autonomy – resembles a more constrained approach due to strong central budget coordination.
