A record 9.5 million UK pensioners are projected to pay income tax in 2026-27, according to official HM Revenue and Customs figures published on Wednesday, July 15, 2026.
Data reveals nearly three million additional retirees entered the tax net since income tax thresholds were frozen in 2021-22.
Consequently, older adults above state pension age now account for 23.5 percent of all taxpayers, up from 21.1 percent a decade ago.
Fiscal Drag and Triple Lock
The policy mechanism has created widespread fiscal drag as inflation pushes pension incomes above the fixed £12,570 personal allowance.
The state pension increases annually based on inflation, average earnings, or 2.5 percent through the triple lock guarantee, while Chancellor Rachel Reeves has extended threshold freezes through April 2031.
By April 2027, the full new state pension is projected to surpass the tax-free allowance for the first time.
Although the government promised measures to prevent state pensioners without other income from paying tax, specific implementation details remain unannounced.
HMRC estimates that the total number of taxpaying pensioners will reach 9.58 million in 2026-27.
This represents a 500,000 increase from the previous tax year and a rise of 2.84 million since frozen limits began.
Analysis from pensions consultancy LCP confirms that more than 70 percent of pensioners now owe income tax.
"The surge in older people paying income tax is continuing, with record numbers of taxpaying pensioners in 2026-27," said Sir Steve Webb, former pensions minister at LCP.
Webb highlighted how tax policy and inflation indexing intersect for retirees.
"The recent extension of the freeze in personal allowances, combined with the continued generous indexation of the state pension means that even more people in retirement can expect to become taxpayers for the first time in the coming years," said Webb.
Revenue generation from threshold freezes extends across the entire taxpayer population.
HMRC projects 40.8 million total income taxpayers in 2026-27, compared to 36.7 million in 2023-24, with higher-rate taxpayers rising to 7.7 million.
Currently, 24 percent of taxpayers pay higher or additional rates, up from 17.5 percent ten years ago, while London sees one-third of taxpayers in top brackets.
"The Treasury has become increasingly reliant on the revenues generated by frozen thresholds," said Shaun Moore of wealth management firm Quilter.
Moore noted the structural shift in government tax strategy.
"What began as a temporary measure has evolved into one of the most effective revenue-raising tools available to government, but the burden falls squarely on the shoulders of UK taxpayers," said Moore.
