This report from UK think tank the Institute of Economic Affairs examines Britain’s inheritance tax system and asks if reform is enough.

Britain has fifth highest tax in the OECD on what parents leave to children, placing it in a small group of high-tax outliers and far above where headline comparisons often suggest.

The tax is arbitrary, distortionary and expensive to administer, it imposes heavy costs on families, deters saving and investment and undermines Britain’s international competitiveness in attracting entrepreneurs and the very rich.
