Burnham urged to launch £26bn tax raid on high earners

Academics have proposed a £26 billion tax increase through raising capital gains taxes and applying national insurance to additional income sources, potentially impacting high earners. The Centre for Analysis of Taxation, a research group comprising academics from the London School of Economics and Warwick University, suggested these reforms would address tax disparities between salaried employees and the wealthiest earners.

This plan has sparked debate in Westminster, as a fiscal headroom of up to £15 billion could prompt the Chancellor to consider substantial tax hikes. The Labour Party platform had previously pledged not to increase income tax, VAT, or national insurance for workers. Critics, including top economists Jim O'Neill and Andy Haldane, argue that changes to capital gains and investment taxes could hinder growth.

A key recommendation is to equalize capital gains taxes with income tax rates, which could generate £19.7 billion by 2030. Researchers also propose implementing employer national insurance contributions on partnership profits and investment income, potentially raising £6.1 billion by the forecast's end. Despite potential concerns about reduced competitiveness and controversy surrounding employer NIC charges for self-employed individuals, proponents argue that these reforms would encourage productivity and fairness in taxation.
