Taxing work and investment across legal forms: pathways to welldesigned taxes

The parts of the UK tax system that dictate how different forms of income are taxed are of central importance and are not fit for purpose. There is a large, unjustified and problematic bias against employment and labour incomes and in favour of business ownership and capital incomes. The tax treatment of returns to investment is a mess: incentives vary depending on the asset type, source of finance and legal structure involved and range from large subsidies to large penalties. And this is just the start; the list of problems is long. Some problems are high profile and periodically subject to tinkering. Others are so baked into the system that they are generally overlooked, yet are no less problematic. There is growing pressure on the current system, notably as a result of rapid growth in the number of people working through their own business (business owner-managers have been the fastest-growing part of the labour market since at least the early 2000s) and increasing strain at the boundary between employment, self-employment and incorporation. Different groups are unhappy with the current system for different reasons: some worry about exploitation of the low-income self-employed, some about inequality related to low capital income taxes at the top of the income distribution and others about complexity and disincentives to enterprise. But these disparate groups seem increasingly united in thinking the current system is not working. In this report, we seek to give people the information and tools needed to: (i) understand the range of problems with the current system for taxing different legal forms of work and how radical reform could largely or completely fix most of them; and (ii) devise smaller reforms that would move the system in the right direction while mitigating the trade-offs inherent in partial reforms.
