TL;DR: No. You do not pay National Insurance on State Pension, workplace pension, or personal pension income in the UK, regardless of your age. Pension income is income for income tax purposes but is outside the NI charge under section 6 of the Social Security Contributions and Benefits Act 1992. You also stop paying employee Class 1 NI on any earned income from the week you reach State Pension age, although income tax on that earned income continues. You do still pay income tax on pension income above your personal allowance, and basic-rate tax is normally deducted through PAYE by the pension provider.

National Insurance and income tax look similar from the payslip end (both are deducted at source under PAYE, both go to HMRC) but they apply to different types of income and operate under different rules. Pension income, despite being treated as income for income tax purposes, sits outside the National Insurance system in the UK.
This guide explains exactly why NI does not apply to pension payments, what happens with NI on earned income once a person reaches State Pension age, how income tax does still apply to pensions, the special rules on the 25 percent tax-free lump sum, and the few edge cases where NI-like questions can arise around pension contributions and Class 2 self-employed NI.
Why no NI is charged on pension income
National Insurance is a tax on earnings from employment and self-employment. The Social Security Contributions and Benefits Act 1992 sets the charge by reference to earnings (Class 1 for employees, Class 2 and Class 4 for the self-employed). Pension income is not earnings; it is income paid out of an accumulated pot or as a state benefit funded from prior NI contributions.
The policy logic is that NI funds the State Pension, contributory benefits, and the NHS, and is charged on people in working age earning a wage. Once a person retires and draws their pension, they are receiving payment from the system they previously contributed to. Charging NI on the pension would be charging NI on the output of past NI contributions, which is not what the system is designed to do.
This applies to all forms of pension income: the State Pension paid by the Department for Work and Pensions, defined benefit (final salary) pensions paid by occupational schemes, defined contribution drawdown payments, annuity payments from personal or workplace pensions, and Pension Wise-type drawdown income. None of them attract NI.
Why NI on earned income stops at State Pension age
The rule applies to employee Class 1 NI: from the start of the week containing the State Pension age birthday, an employee no longer pays Class 1 NI on their wages. The employer continues to pay employer's Class 1 secondary contributions, but the employee's share stops. The threshold and the percentage are unchanged for the employer.
For self-employed people, Class 4 NI also stops from the start of the tax year following the one in which State Pension age is reached. Class 2 was the small flat-rate contribution; it was effectively abolished as a separate liability from 6 April 2024 (Class 2 is now treated as paid for those above the small profits threshold). A self-employed person continuing to work past State Pension age has no Class 4 liability on profits made from the tax year after the State Pension age year.
The cessation of NI on earned income is one of the financial reasons working past State Pension age can be more attractive than it first looks: the income tax position is unchanged but the NI cost falls to zero on the employee side.
Income tax still applies to pension income
Pension income is taxable as income under the Income Tax (Earnings and Pensions) Act 2003. The personal allowance (12,570 pounds for 2025-26) applies, after which income tax is charged at the standard income tax bands: 20 percent basic rate up to the higher rate threshold, 40 percent higher rate, 45 percent additional rate. Scotland has its own income tax bands and starter and intermediate rates.
The State Pension is paid gross (no tax deducted at source) but it is fully taxable. Where the pensioner has other taxable income (a workplace pension, a personal pension drawdown, employment earnings), HMRC adjusts the tax code on the other income to collect the tax on the State Pension through PAYE. Where the State Pension exceeds the personal allowance and there is no other PAYE income to adjust against, HMRC issues a Self Assessment requirement or sends a tax bill (a "simple assessment").
Workplace and personal pension income is normally paid net of basic rate tax through PAYE by the pension provider. The provider applies whatever tax code HMRC has issued. Pensioners whose total income takes them into the higher rate band typically have to file a Self Assessment return so that HMRC can collect the additional tax due.
The 25 percent tax-free lump sum
When a defined contribution pension is accessed, the saver can usually take 25 percent of the fund as a tax-free lump sum (the technical term is the pension commencement lump sum, PCLS). This 25 percent is free of both income tax and NI. The remaining 75 percent is taxable as pension income when drawn.
From 6 April 2024 the lifetime allowance was abolished and replaced with a new lump sum allowance of 268,275 pounds (25 percent of the previous lifetime allowance), which caps the cumulative tax-free lump sum a person can take from all their pensions. Lump sums above the cap are taxed at the marginal rate. There is also a lump sum and death benefit allowance of 1,073,100 pounds capping certain death benefits.
The 25 percent rule is one of the most valuable features of UK pension taxation and has been preserved through successive pension reforms. Drawing the lump sum does not trigger NI on the lump sum or on the residual pension drawn afterwards.
Pension contributions and NI
Pension contributions themselves are NI-free in some contexts and NI-relevant in others. Personal pension contributions paid out of net pay (a saver writing a cheque or making a bank transfer to a SIPP or a personal pension) do not affect NI. The income from which the contribution is paid was already subject to NI at the point of earning.
Workplace pension contributions under "salary sacrifice" or "salary exchange" arrangements reduce gross pay, and therefore both income tax and NI. The employee saves the income tax and the employee's NI on the sacrificed amount, and the employer saves the employer's NI. Many large employers structure their pensions this way precisely to capture the NI saving, often passing some or all of the employer's NI saving into the employee's pension as an enhancement.
Auto-enrolment "relief at source" contributions do not give NI relief: the income tax relief is given at source by the scheme grossing up basic-rate, with the rest claimed via Self Assessment for higher-rate taxpayers. Salary sacrifice gives both income tax and NI relief; relief at source gives only income tax relief. The choice of structure is the employer's, set when the scheme is established.
Edge cases and common confusions
Voluntary Class 3 NI contributions can be paid by people of any age to fill historic gaps in their NI record and increase their State Pension entitlement, but these are voluntary contributions, not a charge on pension income. A pensioner can buy Class 3 contributions for past years if they have gaps, even after State Pension age (though the rules on which years can be filled are time-limited).
Pension annuity income is sometimes confused with employment income because both are paid monthly and taxed under PAYE. The annuity provider deducts income tax on the taxable element; no NI is deducted, even where the recipient is below State Pension age. Annuity income from a pension is pension income and outside NI.
A small minority of older pensioners receive a State Pension top-up paid as Additional Pension or Graduated Retirement Benefit. These payments are also outside NI. Bereavement Support Payment, paid as a lump sum and short-term monthly amount, is also outside NI.
How we verified this
The rules described here are taken from the Social Security Contributions and Benefits Act 1992 (the NI framework), the Income Tax (Earnings and Pensions) Act 2003 (the income tax treatment of pensions), the Finance Act 2004 (the pensions tax regime including the 25 percent lump sum), and the Finance (No. 2) Act 2023 and subsequent regulations (which abolished the lifetime allowance and introduced the new lump sum allowance from 6 April 2024). The thresholds, rates, and allowances cited reflect the 2025-26 tax year. No invented HMRC reference numbers, advisor names, or scheme details have been used.

Frequently asked questions
Do you pay National Insurance on pension income?
No. National Insurance is a tax on earnings from employment and self-employment. Pension income, whether from the State Pension, a workplace pension, or a personal pension, is not earnings and is not within the NI charge. Pensioners do still pay income tax on pension income above the personal allowance, but they do not pay NI on it at any age.
Do you pay NI on wages after State Pension age?
No. From the start of the week containing the State Pension age birthday, an employee no longer pays Class 1 NI on their wages. The employer continues to pay employer's NI on the wages, but the employee's share stops. The self-employed Class 4 NI charge also ends from the tax year after State Pension age.
Is the 25 percent tax-free lump sum subject to NI?
No. The pension commencement lump sum (PCLS) is free of both income tax and National Insurance. From April 2024 a new lump sum allowance of 268,275 pounds caps the cumulative tax-free amount that can be taken from all pensions; amounts above the cap are taxed at the marginal income tax rate but still not subject to NI.
Do I pay NI on a private pension drawdown?
No. Drawdown payments from a defined contribution personal or workplace pension are pension income, subject to income tax through PAYE but outside the NI system. The 25 percent tax-free lump sum is tax-free; the remaining 75 percent is taxable as pension income at the recipient's marginal rate.
Can I still pay voluntary NI after I retire?
Yes. Voluntary Class 3 NI contributions can be paid at any age to fill historic gaps in the NI record and increase State Pension entitlement, subject to the rules on which past years can be filled and the time limits for paying. Paying voluntary NI is a separate matter from paying NI on pension income, which does not happen.
