Could millions of pensioners be just one small income stream away from an unexpected tax bill?
From 6 April 2026, the full new State Pension rises to £241.30 per week — an increase of 4.8% under the triple lock guarantee, confirmed by the Secretary of State for Work and Pensions on 26 November 2025. That works out to roughly £12,548 a year, which sits just £22 below the frozen Personal Allowance of £12,570. For anyone with even a modest private pension, part-time earnings or savings interest, that razor-thin margin could trigger an income tax liability for the first time — and most pensioners are entirely unaware. As bestmortgagesforyou.co.uk has covered across its benefits and finance guides, the devil is often in the detail when it comes to government payment changes.
New research from Royal London suggests that 41% of UK adults do not realise the State Pension is taxable income at all. With the Personal Allowance frozen at £12,570 until at least April 2031, that gap will only narrow further in the years ahead — and the government’s proposed fix will not arrive until the 2027/28 tax year at the earliest.
Key Takeaways
- The full new State Pension rises to £241.30 per week (approximately £12,548 per year) from 6 April 2026 — just £22 below the £12,570 Personal Allowance threshold.
- The basic State Pension (pre-April 2016) rises to £184.90 per week, and those on this system will see a smaller annual increase of roughly £440.
- Any additional income beyond the State Pension — including private pensions, savings interest or part-time work — could push total income above the tax-free threshold.
- The government has proposed a tax waiver for pensioners whose sole income is the State Pension, but this will not take effect until 2027/28 at the earliest.
- Checking tax codes, National Insurance records and State Pension forecasts before April 2026 is strongly advised.
What Is Actually Changing With the State Pension From April 2026
Two significant changes take effect on 6 April 2026: the annual payment increase under the triple lock, and the beginning of the State Pension age rise from 66 to 67. Both carry financial implications that are worth understanding well in advance.
The 4.8% Triple Lock Increase Explained
The triple lock guarantees that the basic and new State Pensions rise each year by the highest of three measures: the Consumer Prices Index (CPI) rate of inflation, average weekly earnings growth, or 2.5%. For 2026/27, the determining factor is average earnings growth for the period May to July 2025, which the Office for National Statistics confirmed at 4.8%.
This means both versions of the State Pension will increase by 4.8% from April — a rate higher than CPI inflation (3.8% for September 2025). The Chancellor confirmed this commitment during the Autumn Budget on 26 November 2025.
Worth noting, the triple lock has been in place since 2011 and has significantly outpaced inflation-linked benefits over time. The Office for Budget Responsibility estimates the policy will cost the government £15.5 billion a year by 2030.
New State Pension vs Basic State Pension — The Exact Figures
Not all pensioners receive the same version of the State Pension, and the difference in weekly rates is substantial. The system divides broadly into two groups: those who reached State Pension age on or after 6 April 2016 (new State Pension), and those who reached it before that date (basic State Pension).
| State Pension Type | 2025/26 Weekly Rate | 2026/27 Weekly Rate | Annual Increase |
|---|---|---|---|
| New State Pension (post-April 2016) | £230.25 | £241.30 | ~£575 |
| Basic State Pension (pre-April 2016) | £176.45 | £184.90 | ~£440 |
| Pension Credit (single, minimum guarantee) | £227.10 | £238.00 | ~£567 |
| Pension Credit (couple, minimum guarantee) | £346.60 | £363.25 | ~£866 |

A common assumption is that every pensioner receives the headline £241.30 figure. In practice, the full new State Pension requires 35 qualifying years of National Insurance contributions, and many receive less due to gaps in their record or contracted-out deductions. Nearly two thirds of state pensioners — around 8.4 million people — are on the older basic system, which pays considerably less.
Why £22 Is the Number Every Pensioner Should Know
Here’s the thing: the State Pension is rising, but so is the risk of being pulled into the income tax net for the first time. The gap between the full new State Pension and the Personal Allowance has narrowed to the point where even trivial amounts of additional income could trigger a tax liability.
The Personal Allowance Freeze Until 2031
The Personal Allowance — the amount of income that can be earned before income tax applies — has been frozen at £12,570 since the 2021/22 tax year. In the November 2025 Budget, the Chancellor confirmed this freeze will continue until at least April 2031 under the Finance (No.2) Bill 2024–26.
When the freeze began in 2021, the full new State Pension was £9,339 per year — well below the threshold. By 2025/26, it reached £11,973. From April 2026, it climbs to approximately £12,548 — leaving a buffer of just £22.
| Tax Year | Full New State Pension (Annual) | Personal Allowance | Gap |
|---|---|---|---|
| 2021/22 | £9,339 | £12,570 | £3,231 |
| 2024/25 | £11,502 | £12,570 | £1,068 |
| 2025/26 | £11,973 | £12,570 | £597 |
| 2026/27 | ~£12,548 | £12,570 | ~£22 |
| 2027/28 (projected) | ~£12,861+ | £12,570 | Exceeds threshold |

This process — known as ‘fiscal drag’ — pulls more people into the tax net without any change in actual tax rates. It affects not only pensioners but also workers on modest incomes; from April 2026, those earning the National Living Wage (£12.71 per hour) will begin paying income tax after roughly 20 hours of work per week.
What Counts as ‘Additional Income’ in HMRC’s Eyes
The State Pension alone may not breach the threshold in 2026/27 — but it comes perilously close. Any income on top of it, no matter how modest, could push total earnings past £12,570. Sources of additional income that HMRC considers include workplace or private pension payments, interest from savings accounts above the Personal Savings Allowance (£1,000 for basic-rate taxpayers), earnings from part-time or freelance work, rental income from property, and dividends from shares outside an ISA.
Bear in mind, the Personal Savings Allowance of £1,000 applies separately, so savings interest below that level would not itself trigger tax. However, if total income (including State Pension) already exceeds £12,570, even modest interest adds to the tax bill.
The Myth That the State Pension Is Tax-Free
A common belief is that the State Pension is exempt from income tax. According to HMRC, however, the State Pension is taxable income — it simply arrives without any tax deducted at source. The Department for Work and Pensions pays it gross, and any tax owed is collected separately.
This distinction catches many pensioners off guard. Research from Royal London found that 41% of adults in the UK had no idea the State Pension counts as taxable income.
How HMRC Actually Collects Tax on State Pension Income
Because DWP does not operate PAYE on State Pension payments, HMRC uses an indirect method. If a pensioner also receives a workplace or private pension, HMRC adjusts the tax code on that second pension to account for the State Pension. This means more tax is deducted from the private pension, effectively collecting tax on both income streams.
For pensioners with no other pension or employment income, HMRC may issue a ‘Simple Assessment’ after the end of the tax year, setting out how much tax is owed and the deadline for payment. The Low Incomes Tax Reform Group has called on the government to bring the State Pension into the PAYE system so that DWP deducts tax before payment — simplifying the process for the approximately 12 million recipients.
Simple Assessment vs PAYE — Which Applies
The method depends entirely on the pensioner’s other income sources.
| Situation | How Tax Is Collected |
|---|---|
| State Pension + workplace/private pension | PAYE — tax code adjusted on the private pension |
| State Pension + employment income | PAYE — tax code adjusted via employer |
| State Pension only (no other income) | Simple Assessment issued by HMRC after year-end |
| State Pension + self-employment income | Self Assessment tax return |

It is worth checking the tax code on any private or workplace pension payslip before April 2026. An incorrect code could mean too much — or too little — tax is being deducted.
Who Will Pay Tax on Their State Pension From 2026/27
Not every pensioner will face a tax bill. However, the £22 margin means the pool of those at risk is larger than many realise. According to figures obtained by pension consultancy LCP through a Freedom of Information request to HMRC, approximately 8.8 million pensioners already pay income tax, with more than one million in the 40% higher-rate bracket.
Pensioners With Small Private Pensions or Savings Interest
Those most likely to be caught out are pensioners who receive the full new State Pension and have even modest additional income. A private pension of just £25 per week (roughly £1,300 per year) would push total income well past the Personal Allowance. Similarly, savings interest from a Cash ISA is tax-free, but interest earned in standard savings accounts above the Personal Savings Allowance is not.
Interestingly, National Savings & Investments (NS&I) Premium Bond prizes are tax-free and do not count towards the Personal Allowance calculation — a detail that may be relevant for pensioners managing their income carefully.
Those on the Old Basic State Pension With Additional State Pension
Pensioners who reached State Pension age before April 2016 receive the basic State Pension (£184.90 per week from April 2026) rather than the new flat rate. This is substantially lower and, on its own, well below the Personal Allowance at roughly £9,615 per year.
However, many of these pensioners also receive the Additional State Pension — sometimes called SERPS or the State Second Pension — which can push total State Pension income significantly higher. In some cases, the combined total exceeds the full new State Pension figure, meaning these pensioners may already be paying tax. The individual amount depends entirely on earnings history and National Insurance contributions during employment.
The Government’s Promise for 2027 — And What It Actually Means
The November 2025 Budget included a notable commitment: the government stated it would ensure that pensioners whose sole income is the basic or new State Pension would not have to pay income tax through Simple Assessment from the 2027/28 tax year onwards, should the State Pension exceed the Personal Allowance.
The Proposed Tax Waiver for State-Pension-Only Households
This waiver would apply until the end of the current Parliament — likely 2029, though an earlier general election is always possible. The Chancellor has said the government is ‘exploring the best way to achieve this’ and will publish further detail in due course.
That said, there are several important caveats. The waiver would only protect those with no additional income beyond the State Pension — a relatively small group. Pensioners with even a small workplace pension, savings interest or part-time earnings would not qualify, meaning the vast majority of those affected by fiscal drag would see no relief. Additionally, the House of Commons Library noted in March 2026 that no further details on implementation have been published since the Budget announcement.
Pension experts have raised fairness concerns as well. As Maike Currie of PensionBee has observed, a pensioner with a tiny private pension could miss out on the waiver entirely, whilst a neighbour on the same total income — but from the State Pension alone — pays nothing. The policy risks creating what commentators have described as ‘cliff edges and anomalies’ that the government will need to resolve carefully.
Five Steps to Check Before April 2026
Preparation is the most effective defence against a surprise tax bill. The following steps can help anyone approaching or already in receipt of the State Pension to understand where they stand.
- Check the State Pension forecast. The GOV.UK tool at gov.uk/check-state-pension shows the projected weekly amount, the number of qualifying National Insurance years on record and the expected State Pension age.
- Review the National Insurance record for gaps. Missing years can be topped up with voluntary Class 3 contributions (currently £17.45 per week per missing year). The deadline for filling gaps from 2006 onwards has been extended, but this window will not remain open indefinitely — it is worth acting sooner rather than later.
- Verify the PAYE tax code. Anyone receiving a private or workplace pension alongside the State Pension should check the tax code on their pension payslip or via the HMRC Personal Tax Account online. An incorrect code could mean overpaying or underpaying tax unnecessarily.
- Estimate total income for 2026/27. Adding up the State Pension, any private pension income, expected savings interest, rental income and earnings gives a clearer picture of whether the £12,570 threshold will be breached.
- Consider ISA-sheltered savings. Interest earned within a Cash ISA or Stocks and Shares ISA does not count towards taxable income. Moving savings into an ISA before the new tax year can help keep total income below the Personal Allowance — the annual ISA allowance remains at £20,000 for 2026/27.
Scam Awareness and Official Contact Details
State Pension changes tend to attract fraudsters. HMRC, DWP and the Pension Service will never contact anyone by text message or email asking for bank details, passwords or upfront payments to ‘release’ a pension.
Anyone who suspects a pension-related scam should report it to Action Fraud on 0300 123 2040, or contact the Financial Conduct Authority’s consumer helpline on 0800 111 6768. The Financial Ombudsman Service handles complaints about regulated financial firms and can be reached on 0800 023 4567.

Closing
The 4.8% triple lock increase from April 2026 is welcome news for the 13 million pensioners who will benefit. However, the collision between rising State Pension payments and a frozen Personal Allowance creates a situation that demands attention — particularly for those with any form of additional income.
