Nigel Farage’s Reform UK party has proposed raising the personal income tax threshold to £20,000. The current personal allowance stands at £12,570, meaning the policy would exempt an additional £7,430 of earnings from tax. Reform UK argues this would benefit working people across income bands. Independent estimates suggest the policy could cost the Treasury between £40 billion and £80 billion annually, depending on secondary effects and policy design. To cover the cost, the party proposes scrapping the UK’s net-zero policies. It argues that ending subsidies and obligations tied to decarbonisation would yield significant savings. Reform UK has pointed to renewable energy subsidies, electric vehicle incentives and building efficiency standards as areas for rollback. The Climate Change Committee estimated government climate spending at around £22 billion annually in its 2023 report. Reform UK also plans deep cuts to public spending. The proposals include reducing the civil service headcount, abolishing public bodies, and freezing departmental budgets. The party claims this would eliminate unnecessary bureaucracy. The Institute for Fiscal Studies notes that while such proposals are common, delivering actual savings on that scale would require service cuts or structural reforms. The party has not released a detailed fiscal framework. There is no official manifesto or breakdown of how much each element of the plan would cost or save. The Office for Budget Responsibility has not been asked to review the proposal. Economists have raised concerns about the lack of independent analysis or modelling. The UK’s deficit remains high by historical standards. According to the Office for National Statistics, public sector borrowing in the year to March 2025 reached £121 billion. This is equivalent to 4.3 per cent of GDP, above the pre-Covid average. Farage is using the tax pledge to define the party’s pitch ahead of the election. Reform UK is seeking to attract voters dissatisfied with the Conservatives. The policy forms part of a broader plan to position the party as a pro-worker, anti-establishment alternative. No timetable has been provided for the proposed tax change. It is not clear whether the new threshold would be introduced in a single year or phased in. The party has also not clarified whether the policy would be subject to parliamentary or departmental review....
