This is Money explained the reasons behind a long-standing question about why state pensions are subject to income tax whilst other benefits, including Universal Credit and Personal Independence Payment, are not taxed at all.
The UK social security system divides benefits into three categories. National Insurance benefits, which include the state pension, Jobseekers Allowance, Employment Support Allowance and Bereavement Support Payments, are generally taxable. Means-tested benefits such as Universal Credit, Pension Credit and Housing Benefit are not taxed. A third category comprises 'extra cost' benefits like Attendance Allowance, Personal Independence Payment and Child Benefit, which are also not taxed. The original reasoning behind this structure dates back to the system created after the Second World War. National Insurance benefits were designed to provide insurance against loss of earnings from unemployment, sickness, old age or widowhood. Since someone earning normally would have paid income tax on their salary, it followed logically that a benefit replacing that income should also be taxable.
The justification for not taxing means-tested benefits differs fundamentally. These payments aim to bring recipients up to a bare minimum standard of living by topping up other income to a set threshold. If such benefits were taxable, paying tax could push recipients below that minimum level they were deemed to need, defeating the purpose of the payment. Similarly, 'extra cost' benefits seek to place disabled people or parents in the same financial position as those without those extra costs. Taxing disability benefits, for example, could claw back 20 per cent or more, leaving disabled people still worse off than those without disabilities.
This creates situations where someone on means-tested benefits may receive more support than a pensioner paying tax on a deferred state pension. Means-tested benefit recipients can access 'passported benefits' including free prescriptions, help with rent and council tax, and assistance with energy bills. Whilst some support tapers gradually as income rises, others operate on a cliff-edge system where recipients just above the benefit threshold lose all assistance. This is particularly unfair where someone has deferred their pension or accumulated modest savings, as these push them above benefit thresholds entirely.
For savers and pensioners in the UK, this means someone who has worked long and saved modestly may pay tax on pension income whilst receiving fewer total benefits than someone on Universal Credit with access to additional passported support.
This is Money's agony uncle noted that whilst governments could theoretically tax these additional benefits, doing so would undermine their purpose, potentially leaving people unable to afford rent or prescriptions. The system reflects an awkward balance between having benefits available to all versus limiting support to those on low incomes, with no perfect solution where all outcomes feel equitable.
