Millions of UK pensioners are expected to be excluded from the government’s proposed state pension tax exemption, with experts warning the scheme could create unfair outcomes and sharp financial cliff edges. New analysis shows only a small fraction of retirees will actually benefit from the policy, which is due to begin in the 2027/28 tax year.
Who Will Benefit
Analysis by pension consultancy LCP finds that just around 5.4% of Britain’s pensioners—roughly one in 18—are likely to qualify. Those born before April 6, 2016, who reached state pension age under the old system, will be entirely excluded, even if their total retirement income is identical to someone on the new system. This raises concerns about inequality between pensioners on different schemes.
Why Pensioners Could Start Paying Tax
Under the triple lock, the state pension rises each year by whichever is highest of inflation, average earnings growth, or 2.5%. Meanwhile, the personal allowance, currently £12,570, is frozen until 2030. This means the full new state pension could exceed the tax-free allowance from April 2027, resulting in pensioners receiving tax bills from HMRC.
Experts estimate these bills could rise quickly: about £88 in 2027/28, £153 in 2028/29, and £220 in 2029/30. While the government pledged a tax exemption for these pensioners, the proposal applies only to those whose sole income is the basic state pension with no additions or increments.
Cliff Edges and Complexity
LCP’s analysis shows that most retirees will still receive nothing. Out of roughly 13.2 million pensioners, around 7.7 million on the old system automatically miss out, and the majority of the 5 million on the new system also fail to qualify due to additional income or overseas residency.
Experts warn the system creates sharp “cliff edges.” Even receiving £1 of taxable income outside the state pension could disqualify a retiree from the exemption. Small workplace pensions, savings income, or annuities could unintentionally trigger significant tax bills.
Inequalities Between Pensioners
Former pensions minister Steve Webb said the policy creates differential treatment. Two pensioners with identical total income may face entirely different tax liabilities simply because one receives the new state pension while the other receives the old pension plus SERPS or the State Second Pension. Alasdair Mayes, LCP pensions expert, said the scheme adds complexity rather than simplifying retirement finances. “A simple and transparent tax system would benefit all,” he noted.
The proposal highlights the challenges the government faces in balancing rising state pensions with frozen tax thresholds. Without careful adjustment, millions of pensioners could face unexpected tax bills while only a small minority receive relief.
