A key problem in tax research is that quantitative information is often only available for tax rates, not tax bases. This column introduces a new IMF database on tax reforms published, which uses text-mining techniques to infer multiple dimensions of tax reforms enacted in 23 advanced and emerging economies over the last four decades. The database, which covers both direct and indirect taxes, can help address well-known methodological pitfalls in existing tax research and offers opportunities for novel analysis of tax policy.

Many countries exempt foreign-sourced income from taxation at home, with income taxed only in the source country. In 2009, the UK moved from a system of tax credit to a system of tax exemption of foreign-earned income of firms. This column looks at the effects of this reform on firm behaviour. Immediately following the reform, firms were induced to pay significantly more dividends to the UK and decreased their investments. But neither effect persisted in the long run.
