The number of state pensioners being sent dreaded letters from HMRC is set to soar, with around 820,000 expected to pay income tax on their Department for Work and Pensions (DWP) state pension alone within two years. The warning comes as the Triple Lock pledge, introduced in 2011 by the Conservative-Liberal Democrat coalition, continues to push annual pension increases above the personal tax-free allowance threshold of £12,570.
Triple Lock Drives Pensioners Over Tax Threshold
Under the Triple Lock, the state pension rises each April by the highest of average earnings growth, inflation, or 2.5%. At £241 per week, a full new state pension is now £30 per week—14% higher—than it would have been under average earnings indexation since 2011. This has dragged more pensioners into income tax liability, with an estimated 820,000 set to be affected by 2027/28. In total, 12 million pensioners could eventually be impacted as payments climb above £12,570.
Growing Cost of State Pension
State pension spending has risen from around 3.5% of annual economic output (GDP) at the turn of the century to approximately 5% today. This makes it the second-largest individual area of public spending after the NHS, putting pressure on government finances.
Expert Calls for Careful Reform
Maike Currie, VP Personal Finance at PensionBee, commented: "It's important not to present the Triple Lock divisively, as a choice between supporting pensioners and supporting younger people. Rising youth unemployment and the growing number of young people who are not in education, employment or training are complex, structural challenges that require targeted solutions."
She added: "Pensioners also need protection against inflation, particularly those who rely heavily on the state pension and have limited private pension savings, so any reforms to the Triple Lock should be carefully considered and accompanied by a clear, credible alternative that gives people confidence to plan for the future."
Complex Interaction with Frozen Tax Thresholds
Ms Currie noted: "The challenges over taxing the State Pension highlights just how complicated the interaction between the Triple Lock and frozen tax thresholds has become. Any changes need to be carefully designed so pensioners pay the right amount of tax without creating unnecessary complexity or confusion."
She concluded: "More broadly, the ongoing Triple Lock debate is a reminder that pension policy can and does change. We've seen reforms to the State Pension age, National Insurance and tax allowances over the years. While the Triple Lock remains in place today, no government can guarantee what the system will look like decades from now. The State Pension provides an important foundation, but it shouldn't be the only pillar of retirement planning. Building up a private pension gives people greater choice, flexibility and financial resilience, regardless of how future governments choose to reform the system."
