TL;DR: Working after reaching State Pension age in the UK has significant disadvantages alongside the obvious benefits of additional income. The main downsides are: continued income tax on earnings (with the State Pension counting as taxable income), the loss of certain age-related benefits and reliefs when income exceeds thresholds, complex tax code interactions where multiple income sources need careful allocation, the impact on means-tested benefits like Pension Credit and Council Tax Reduction, the potential reduction in time available for healthcare appointments and family care responsibilities, and the limited employment protection some older workers experience in practice. National Insurance is no longer payable on earned income from State Pension age, which is one clear advantage that offsets some of these costs.
Last reviewed May 2026
The decision to continue working after reaching the UK State Pension age (66 in 2026, rising to 67 between 2026 and 2028) is a complex one. It is no longer a binary "retire fully or work full-time" choice: phased retirement, part-time roles, consultancy and self-employment all sit between full retirement and continuing full employment. The disadvantages of working after State Pension age sit alongside the obvious advantages of additional income and the social and cognitive benefits of continued engagement.
This guide covers the main disadvantages: the tax position on combined income from work and pension, the impact on means-tested benefits, the loss of age-related allowances at higher incomes, the practical employment-rights and age-discrimination considerations, the impact on the State Pension itself, and the trade-offs around time, health and family.
Income tax on combined pension and earned income
The State Pension is taxable income in the UK. When combined with earnings from continued work, the total income is taxed according to the relevant income tax bands. The Personal Allowance (12,570 pounds in 2026-27) covers the first slice of total income; income above that is taxed at the basic rate (20 percent), then higher rates above the band thresholds.
For someone receiving the full new State Pension (currently around 11,500 pounds annually with the 2026 triple-lock uprating) and earning a modest 15,000 pounds from part-time work, the total income of 26,500 pounds puts them in the basic-rate band. The tax bill is roughly 2,786 pounds (20 percent on 13,930 pounds above the allowance). Without the part-time work, the tax bill would be 0 (the State Pension alone is below the allowance).
The State Pension is paid gross (without tax deducted), so the tax due on it is collected through PAYE on the earned income (with the tax code adjusted to reflect the State Pension) or through Self Assessment. Many older workers are caught out by an unexpected tax bill in the first year of combined income because the tax code does not catch up immediately.
The tax code complications of multiple income sources
Someone with three income streams (State Pension, private pension, part-time work) often has a tax code on each that allocates the Personal Allowance to one source and applies BR (basic rate) or D0 (higher rate) to the others. The mechanics work in theory, but in practice the codes can be misaligned, particularly in the first year of combined income or after a change in circumstances.
Common code issues include: HMRC's estimated State Pension figure being out of date (the code does not update automatically with the annual triple-lock uprating, leading to a small underpayment); the tax code for the part-time job being on BR when a split allocation would be more efficient; or untaxed savings and dividend income from retirement investments not being captured in the code.
HMRC's Personal Tax Account shows the current code allocations and the assumptions driving them. Older workers should check the figures each April when the new tax year starts, and again if any income source changes during the year. The end-of-year P800 calculation reconciles any errors, but in-year corrections avoid a year-end shock.
The disappearance of National Insurance: the offsetting advantage
The clearest advantage of working past State Pension age is that National Insurance Class 1 (employee) and Class 4 (self-employed) contributions are no longer payable on earnings. Class 1 saves 8 percent of earnings between 12,570 and 50,270 pounds for an employee in 2026-27. Class 4 saves 6 percent of self-employed profits in the same band.
This NI saving is significant. For an earner of 25,000 pounds past State Pension age, the saving is roughly 996 pounds a year compared to a younger earner with the same salary. The employer's NI (Class 1 secondary, currently 13.8 percent above the secondary threshold) continues to apply, but that is the employer's cost, not the employee's.
The employer remains liable for employer NI on the over-State-Pension-age employee's earnings, which is one of the cost considerations employers weigh when hiring or retaining older workers. It does not change the employee's take-home pay but can affect the willingness of employers to extend or offer roles to older workers.
Loss or reduction of means-tested benefits
Pension Credit, the means-tested top-up to the State Pension for lower-income pensioners, is reduced or removed by additional earned income. Pension Credit's Guarantee Credit element tops a pensioner's weekly income up to 227.10 pounds for a single person in 2026-27 (or 346.60 pounds for a couple). Additional earned income reduces the Pension Credit pound-for-pound after a small disregard.
The loss of Pension Credit can have knock-on effects beyond the cash: Pension Credit is a "passport" benefit that opens entitlement to Housing Benefit (or its successor in Universal Credit areas, although State Pension age claimants remain on the older system), free TV licences for over-75s, Council Tax Reduction in many local authority schemes, NHS dental and prescription help, and certain Cold Weather Payments and Winter Fuel Payment top-ups. Losing Pension Credit can lose all of these.
For someone close to the Pension Credit threshold, taking on a few hundred pounds of additional weekly income can result in losing more in benefit entitlements than is gained in wages. The arithmetic is sensitive and should be checked with a benefits adviser at Citizens Advice or Age UK before deciding to take on paid work.
The Personal Allowance taper at incomes above 100,000 pounds
For higher-earning older workers, the Personal Allowance starts to taper at incomes above 100,000 pounds: the allowance is reduced by 1 pound for every 2 pounds of income above the threshold, with the allowance fully removed at 125,140 pounds. The effective marginal tax rate in this band is 60 percent (40 percent income tax on the additional income plus 20 percent on the reclaimed allowance), which is the highest marginal rate in the UK system.
Older workers with a substantial private pension plus continued earnings can find themselves in the 100,000-125,140 pound band, paying the 60 percent marginal rate. Pension contributions, charitable donations and other allowable deductions can reduce the income figure for the taper test, but the planning requires care.
The Personal Savings Allowance and Dividend Allowance also taper or change at the higher rate thresholds. A retiree with significant investment income from ISAs, dividends and savings, combined with continued earnings, faces a complex set of rate band interactions.
Impact on the State Pension itself
Working past State Pension age does not normally increase the State Pension entitlement, because additional NI contributions cannot be made past State Pension age (with one exception described below). The State Pension is fixed based on the NI record up to State Pension age.
State Pension deferral is the exception: a person who reaches State Pension age can choose to defer claiming the State Pension. Deferral increases the eventual State Pension by 1 percent for every 9 weeks of deferral (around 5.8 percent per year) under the post-April-2016 rules for those reaching State Pension age on or after 6 April 2016. For someone in good health expecting a long retirement, deferral can be valuable. For someone in poor health or with a short life expectancy, deferral is rarely worthwhile.
The State Pension also affects the tax code while deferral is in progress (because there is no State Pension to add to the code's calculation) and afterwards (because the deferred-and-increased pension is higher when it eventually starts). The deferral arithmetic should consider the full long-term position, not just the immediate income.
Practical workplace and health considerations
Age discrimination is unlawful under the Equality Act 2010 in the UK. In practice, older workers can still face workplace challenges: assumptions about technology comfort, the absence of structured progression paths, performance management approaches calibrated to younger workforces, and an implicit pressure to retire at "the normal age" even though no normal age exists in law.
Health is the other significant variable. Working past State Pension age requires physical and cognitive capacity. For some, the structure and engagement of work is health-protective. For others, working past the point of comfortable capacity leads to burnout, mistakes and a worse retirement when it eventually comes. The right answer is individual; the wrong answer is to keep working out of inertia.
Time has an opportunity cost. Working takes time that could otherwise be spent on family care (older workers are often the only available childcare for grandchildren, or the only adult available to care for ageing parents), travel, learning, volunteering or leisure. The decision to keep working should weigh this trade-off explicitly rather than treating work time as cost-free.

Frequently asked questions
What are the main disadvantages of working after State Pension age in the UK?
The main disadvantages are: continued income tax on earnings combined with the State Pension, complications in tax codes across multiple income sources, possible loss of Pension Credit and the passport benefits it unlocks, the Personal Allowance taper at incomes above 100,000 pounds, time pressure on health and family commitments, and the limited practical employment protection some older workers experience. National Insurance no longer being payable on earnings is the main offsetting advantage.
Do I pay National Insurance if I work past State Pension age?
No. Class 1 employee NI and Class 4 self-employed NI cease at State Pension age. This saves 8 percent of earnings between the primary threshold and the upper earnings limit (a substantial amount for moderate earners). Employer NI (paid by the employer, not the employee) continues. The employee's take-home pay therefore benefits from the NI exemption.
Does the State Pension count as income for tax purposes?
Yes. The State Pension is taxable income in the UK. It is paid gross (without tax deducted) and is included in the total income figure used to calculate the tax due. For most pensioners, the State Pension alone is below the Personal Allowance, but adding earnings or a private pension typically pushes total income above the allowance, triggering income tax.
Will working after State Pension age affect my Pension Credit?
Yes. Pension Credit is means-tested. Additional earned income reduces the Pension Credit entitlement after a small disregard. Losing Pension Credit can also remove passport benefits like Housing Benefit, free TV licences for over-75s, Council Tax Reduction in many local authority schemes, and NHS dental and prescription help. A benefits check before starting paid work is sensible.
Can I defer my State Pension and keep working?
Yes. State Pension deferral is voluntary: a person at State Pension age can choose to defer claiming. Deferral increases the eventual State Pension by around 5.8 percent for each year deferred (under the post-April-2016 rules). For someone in good health expecting a long retirement, deferral can be valuable; for someone in poor health, it is rarely worthwhile because the increased pension is only paid for as long as the person lives.
