A further 16% of respondents stated that the Autumn Budget itself serves as the decisive reason for their planned departure.Analysis from New World Wealth projects that 9,500 millionaires are set to leave the UK during 2024 - the second-largest outflow globally - in anticipation of reported tax plans. However, in addition to the nation's wealthiest residents, new national research from Cornerstone Tax has found that a significant portion of society has expressed deep concerns over potential tax plans and retirement issues, with 32% of the population citing changes in the tax system as the main reason they would leave the UK.The Autumn Budget, to be delivered by Chancellor Rachel Reeves on 30th October, is expected to introduce reforms affecting inheritance tax relief; impose higher taxes on capital gains (CGT) along with adjustments to CGT exemptions; increase taxes on investment income; alter pensions tax relief and tax-free allowances; and modify Business Assets Disposal Relief. Cornerstone's first-of-its-kind report reveals that if Brits act on their intentions, the UK economy could face significant losses amounting to billions of pounds in business and property revenue, as well as investment-weighted assets.

David Hannah, Group Chair of Cornerstone Tax, emphasises how new economic policy could shift where Brits intend to house their families, money, businesses and futures: "Our data highlights a clear issue that there are significant concerns amongst Brits regarding the new Labour government and its impending Autumn Budget. With proposed increases to Capital Gains Tax and Inheritance Tax, it's no surprise that 16% of the population agree that this budget will be the deciding factor in their decision to leave the UK. The thought of rising taxes amidst a cost-of-living crisis is pushing people to reconsider their futures.“What we're now seeing is a significant shift in where Brits intend to house their families, their money, and their businesses. Our research shows that 32% of individuals are contemplating a move abroad due to these tax changes, with 23% considering relocating their families and 21% thinking about taking their businesses overseas. These are not just fleeting thoughts — they are serious intentions for many Brits as they seek more favourable conditions elsewhere.“Moreover, our research highlights that 29% of Brits believe that renting property abroad offers greater advantages than maintaining a mortgage in the UK, reflecting the profound impact of the ongoing housing crisis. This situation has left many feeling trapped in a challenging market, prompting them to seek better alternatives overseas.
