Find out how taxes and cash benefits affect the incomes of working-age families across countries and over time. The OECD has taken all the complex legal rules used to calculated tax and benefit amounts and put them into a simple web calculator.
The OECD Policy Descriptions describe in detail the rules for calculating the main tax liabilities and social benefits for the working age population in each OECD and EU country.
The reports are updated annually and use a common format to facilitate comparisons between countries and the monitoring of policy reforms over time.
The OECD TaxBEN methodology and manual describes key modelling concepts such as the treatment of regional differences, the family types and labour market characteristics that are currently supported by the model, its policy scope, and the assumptions underlying the calculation of taxes and benefits. The document also describes how to use the web calculator and the underlying STATA command. The STATA command is available through a dedicated online platform, which may be accessible after the review of the application process (please contact the OECD team for additional information).
