Chancellor John Healey has dismissed proposals to increase the capital gains tax (CGT) in the upcoming Budget, choosing not to align it with the higher rates applicable to income tax. The decision comes amid ongoing debate over the fairness and effectiveness of taxing investment profits at the same rate as earned income.
Capital gains tax is levied on the profit made from selling assets such as property or shares. Critics argue that the current system allows wealthier individuals, who often earn significant income through investments, to pay a lower effective tax rate than wage earners. Notably, investor Warren Buffett has previously highlighted that he paid a lower tax rate than some of his staff, an example frequently cited by proponents seeking to equalise CGT and income tax.
Within the Labour Party, voices from both the left and more moderate wings, including Deputy Leader Louise Haigh and Wes Streeting, have advocated for raising CGT as a means to impose a more progressive, wealth-focused tax system. Supporters frame the measure as a “wealth tax that works,” aimed at addressing economic inequality.
However, Healey’s stance reflects concerns about the broader economic impact and government revenue implications. Increasing CGT at this juncture, he and others suggest, risks discouraging investment and might not yield the additional tax income anticipated.
Historical precedent supports this caution. When Nigel Lawson, Chancellor under Margaret Thatcher, announced a hike in CGT to 40 percent in 1988, a rush among investors to realise gains before the tax increase temporarily boosted revenues. Yet, subsequent years saw government receipts decline, with no net revenue gain over the following five years. Analysis by Tax Policy Associates, an independent think tank, attributes this to accelerated asset sales ahead of tax changes and increased tax avoidance strategies.
Similar patterns emerged in Scotland, where increasing the top tax rate to 48 percent reportedly led to a £22 million decrease in revenue, according to the same think tank. Wealthier taxpayers frequently have access to legal avenues for tax mitigation, reducing the effectiveness of higher rates in raising government funds.
Economists and policymakers warn that while redistributive tax policies remain important, measures perceived as hostile to investment could prompt capital flight or reduced economic activity, ultimately undermining the state’s fiscal position.
John Healey’s decision to hold off on raising CGT comes as Britain faces significant debt challenges and economic uncertainty. This approach prioritises steady revenue streams and economic stability over immediate attempts at redistributive taxation. As the forthcoming Budget approaches, the Chancellor faces continued pressure to balance fairness with fiscal pragmatism, navigating a complex political and economic landscape.
