The productivity cost of low Capital Gains rates

9 October 2024 – Equalise Capital Gains Tax rates with Income Tax rates to support productivity and growth, argues new report from the Centre for the Analysis of Taxation (CenTax).
At least half of all capital gains are actually income from work. The top rate of tax on work is 47%, while for capital gains it varies between 10% and 28%. The preferential rates offered to capital gains encourage work through personal service companies, to allow income from work to be taxed at these lower rates.
Almost all gains on unlisted shares (89%) comes from companies with apparent average annual returns above 100%. While a small number of individuals might by chance consistently double their money year after year, this overwhelming pattern is clearly indicative of returns coming from work not capital.
This pattern is true even for many large gains. A third of all large capital gains (>£5 million) from businesses had initial investments of under £500.
HMRC attempts to clamp down on this behaviour have helped to highlight some of the problem. A pre-announced 2016 reform that aimed to make it harder to regularly pay out income as capital gains, led to a tripling in the rate of company liquidations. Since the CGT rate itself was unchanged, this behaviour can only be explained by ‘forestalling’, as individuals attempted to benefit from CGT treatment one final time before the new rules were in place.
These findings come from new research by the Centre for the Analysis of Taxation (CenTax). This used de-identified administrative data from HMRC to examine the share of gains which appear to be income, as well as information on company liquidations from Companies House linked to company characteristics from the Bureau van Dijk’s Orbis database to study responses to past anti-avoidance reforms.
Arun Advani, Director of CenTax and Associate Professor at University of Warwick, said: “Although people tend to assume higher Capital Gains Tax rates are bad for investment, they too often miss that lower rates are bad for productivity and growth through the effect on how people work. Equalising rates with Income Tax, and providing an investment allowance to support investment, could square the circle by raising money while supporting growth.”
Andy Summers, Director of CenTax and Associate Professor at LSE, said:
“Reams of legislation exist just to police the boundary between capital gains and income. Equalisation would be a massive simplification, by allowing these to be eliminated at a stroke.”
Andrew Lonsdale, Research Economist at CenTax, said:
“The fact that one in three business disposals with over £5 million in gains had less than £500 originally invested makes it clear that low Capital Gains Tax rates are being regularly applied to returns that aren’t actually from capital.”
