Since its foundation in the 1960s, the IFS has been studying developments in the UK's tax and social security system. This continues to be a core part of the Institute's work, making a particularly important contribution to public debate around the government's annual set pieces of the Budget and Pre-Budget Report, and the Institute's own Green Budget. Research at the IFS concentrates on describing and analysing changes and proposed changes to the tax and social security system, and in using large cross-sectional household datasets to model the impact of reforms on individuals' incomes and behaviour. Below, we present specific projects that researchers at the IFS have worked on in recent years, although the constant need to maintain the Institute's tax and benefit model means that IFS researchers are familiar with almost all areas of personal tax and social security in the UK.

A notable feature and principal virtue of Tax by Design is its system-wide perspective on different elements of the tax system. This review essay builds on this trait and offers a more explicit foundation for the report's general approach, drawing on a distribution-neutral methodology that is developed in other work.
