A new study warns that extending Capital Gains Tax to main residences could reduce home sales, inflate prices, and influence voter behaviour ahead of the upcoming Budget, sparking economic and political concerns.
A recent study by financial brokerage Boon Brokers highlights significant potential repercussions of proposed Capital Gains Tax (CGT) reforms on the UK housing market. These reforms, which may be announced in the upcoming Budget, could introduce CGT on profits made from selling main residences—a departure from the current system that exempts primary homes from such taxes. The poll, involving 1,000 homeowners, found that 71% would be less likely to sell their main home if these changes were implemented, signalling a likely reduction in housing market supply.
Under the existing tax rules, CGT only applies to gains from second homes, investment properties, shares, and other assets. However, speculation ahead of the November 26 Budget suggests the Treasury is considering extending CGT to primary residences, though details such as tax rates, thresholds, and exemptions remain undisclosed. The Boon Brokers survey showed reluctance to sell was consistent across age groups, with over 80% of those aged 55 and over less inclined to sell, alongside 76% of 18-24-year-olds.
Gerard Boon, the managing director of Boon Brokers, emphasised the possible market impact: “When fewer homeowners are willing to sell, supply will naturally constrict, driving up competition and prices. This imbalance between supply and demand doesn’t just impact affordability, it could stagnate the market and place greater pressure across all levels of the housing market.” The survey also revealed strong opposition to CGT on primary homes, with 73% of respondents rating the move as unfair and 97% disagreeing that it was the fairest method to balance public spending.
Public sentiment also indicates potential political ramifications. When asked how CGT reform might affect Labour’s chances in the next general election, 78% believed it would reduce the party’s prospects, with 45% seeing a significant negative impact. This suggests that beyond market dynamics, the reforms could influence voter behaviour and electoral outcomes.
The broader context of these proposed changes is part of a wider government strategy to rebalance the property market and address fiscal challenges. Recent years have seen alterations to property-related taxes such as Stamp Duty Land Tax (SDLT) and Council Tax, aimed at curbing property accumulation by investors and generating additional revenue. Fiscal policy shifts, including aligning CGT rates closer to income tax rates, are expected to increase tax burdens on landlords and investors, possibly triggering a surge in property sales prior to changes taking effect. This could lead to short-term market instability and reduced rental availability.
Moreover, speculation around property tax reforms, including the potential replacement of stamp duty with a progressive property tax, is already creating market uncertainty. This heightened caution among buyers contributes to slower transaction rates and hesitancy in the housing sector, compounding effects from the CGT reform debate. Industry experts also warn that reductions in CGT allowances, scheduled in the short term, could dampen property transactions and affect prices, particularly influencing landlord and investor decisions.
Taken together, these factors indicate that the proposed CGT reforms could reshape the UK housing market both economically and politically. While intended to bolster public revenues and promote fairness, the changes risk constraining supply, inflating prices, and affecting voter sentiment, underscoring the complexity of balancing fiscal policy with market and social considerations.
