Around 820,000 state pensioners are expected to start paying income tax on their Department for Work and Pensions (DWP) state pension alone within the next two years. This increase is largely driven by the Triple Lock guarantee, which ensures the state pension rises each April, causing many pensioners’ income to surpass the HMRC personal tax-free allowance threshold.
Looking ahead, up to 12 million pensioners could eventually be affected as their state pension payments climb above the £12,570 tax-free allowance. By the 2027/28 tax year, an estimated 820,000 pensioners will owe income tax on their State Pension alone.
The Triple Lock, introduced in 2011 by the Conservative-Liberal Democrat coalition government, guarantees an annual pension increase of whichever is highest: average earnings growth, inflation, or 2.5%. Thanks to this policy, a full new state pension, currently around £241 per week, is about £30 weekly (14%) higher than it would have been had increases followed only average earnings since 2011. Consequently, state pension spending has grown from roughly 3.5% of GDP at the turn of the century to around 5% today, making it the second-largest area of public expenditure after the NHS.

Maike Currie, Vice President of Personal Finance at PensionBee, emphasizes the complexity of the issue. “It’s important not to frame the Triple Lock as a choice between supporting pensioners or younger generations. Challenges like youth unemployment require targeted approaches, while pensioners need protection from inflation, especially those relying heavily on state pensions with limited private savings. Any reforms to the Triple Lock must be carefully thought through and paired with credible alternatives to help people plan their financial futures confidently.”
Currie further explains, “The complicated interaction between the rising State Pension and frozen tax thresholds makes taxing pensions a challenge. Changes must ensure pensioners pay a fair tax share without introducing unnecessary complexity or confusion.”
She adds that the ongoing discussions about the Triple Lock highlight that pension policies evolve. “We’ve seen multiple reforms to the State Pension age, National Insurance, and tax allowances over time. While the Triple Lock remains today, no government can guarantee its future. The State Pension forms a vital base for retirement income, but it shouldn’t be the sole pillar. Building private pensions offers individuals more choice, flexibility, and financial security regardless of future policy changes.”
