Reform UK has pledged to raise the tax-free personal allowance from £12,570 to £15,000 within the first 100 days of a Reform government, should the party win the next general election. The commitment, to be announced by would-be Chancellor Robert Jenrick at Reform's Birmingham conference, is aimed at reversing years of "stealth" tax rises caused by the freezing of thresholds under successive Labour and Conservative governments, a policy currently set to continue until 2031.

Reform says the change would save most taxpayers around £500 a year, benefit roughly 40 million people, lift 2.9 million out of income tax entirely, and keep the state pension untaxed. The party estimates the move would cost £17.7 billion in its first year, rising to £21 billion by year five, to be funded through £80 billion of spending cuts already identified, including reductions to welfare, Net Zero spending and foreign aid. Jenrick reaffirmed Reform's longer-term ambition of a £20,000 allowance and challenged Prime Minister Andy Burnham to match the pledge, as the party sought to move past a donations row that overshadowed the first day of its conference.
