The UK government's proposed income tax 'waiver' for pensioners, intended to exempt those whose sole income is the state pension, is facing scrutiny over potential exclusions. Details remain pending, but early analysis suggests individuals who have deferred taking their state pension—and consequently receive higher payments—may not qualify for the exemption. This uncertainty complicates decisions for those currently considering deferring their pension benefits.

The government has stated its commitment to ensuring that individuals whose only income is the full new or basic state pension, without any increments, will not pay income tax. However, the specifics of this policy are still being finalized. The full rate of the state pension is projected to exceed the basic rate income tax threshold of £12,570 annually in the coming spring. An industry study indicated that only about one in eighteen pensioners would benefit from such a waiver.

Under current rules, deferring the state pension results in an increased payout, with an additional 5.8% added for each year deferred. Those who reached state pension age before April 2016 have a more generous deferral rate of 10.4% per year, or the option of a lump sum with interest. Experts suggest that individuals with any form of 'increments' on their state pension, including those earned through deferral, are likely to be excluded from the proposed tax waiver.

This potential exclusion could significantly reduce the financial benefit of deferring a pension, potentially costing individuals hundreds of pounds annually. Concerns have been raised that the current lack of clarity makes it difficult for people to make informed decisions about their retirement income now.

Many pensioners already pay income tax due to private pensions, occupational pensions, or earnings from Serps or S2P during their working lives. These individuals, along with those who have deferred their state pension, are among those who could miss out on the planned tax exemption. The policy's design may create a divide between exempt pensioners and those who continue to face tax obligations, with increasing financial implications over time.

For instance, LCP estimates that a pensioner solely reliant on the new state pension, currently around £12,548 annually, might save approximately £88 in income tax in the 2027-28 tax year, rising to £220 by 2029-30. However, specific groups appear set to be disqualified. This includes individuals with even a small amount of other taxable income, recipients of the pre-2016 state pension combined with Serps, and those who have deferred their state pension.

One individual who deferred their pension in 2020-21 reported receiving an extra £11.48 per week, totaling an annual pension of over £13,000. This increase, a result of following government guidance to defer, could disqualify them from the proposed tax waiver, forcing them to pay tax on income above the personal allowance. They noted that while their standard pension increases with the triple lock, the deferral increment is adjusted based on inflation, leading to a fear of being financially overtaken by pensioners who did not defer.

Looking ahead, the next state pension increase is anticipated to be influenced by wage growth figures. If average earnings growth remains around 4.1%, the new state pension could rise by approximately £500 annually from April 2027. The Treasury has reiterated its commitment to the tax waiver for those with no income other than the state pension and no increments, highlighting the benefit of the triple lock which is expected to increase incomes for 12 million pensioners this year.
