The Benefit and Wages portal is a platform containing resources to facilitate evidence-based analysis of tax-benefit systems. It includes detailed descriptions of taxes and benefit rules in OECD and EU countries as they apply to working age families. It also includes outputs from the OECD tax-benefit model, which put all these complex rules into a unified methodological framework that enables international comparisons of how tax liabilities and benefit entitlements affect the disposable income of families in different labour-market circumstances.
