Quick answer: for many defined contribution pensions, up to 25% can be tax free, subject to the remaining Lump Sum Allowance. The rest is taxable income. Use the pension withdrawal tax calculator to combine a proposed withdrawal with other income for 2026/27.
The 25% tax-free rule and the Lump Sum Allowance
GOV.UK says most people can usually take up to 25% of pension benefits as a tax-free lump sum. Since 6 April 2024, the standard Lump Sum Allowance limits tax-free lump sums across pensions to £268,275. People with protected allowances can have a higher limit, while previous benefit crystallisations or lump sums can reduce the amount still available.
The 25% is not necessarily 25% of every cheque. A person can designate funds to drawdown, take the associated pension commencement lump sum and leave taxable funds invested. Alternatively, an uncrystallised funds pension lump sum normally contains 25% tax-free and 75% taxable in the same payment. Provider terminology matters.
Main ways to access a defined contribution pension
| Method | How cash is taken | Typical tax treatment | MPAA point |
|---|---|---|---|
| Pension commencement lump sum plus drawdown | Tax-free cash, rest invested | Tax-free cash within allowance; later drawdown taxable | Normally when taxable flexible income starts |
| UFPLS | Each payment comes directly from uncrystallised funds | Usually 25% tax free and 75% taxable | Normally triggered by first UFPLS |
| Full-pot cash withdrawal | Whole pot paid | Usually 25% tax free and 75% taxable | Normally triggered unless small-pot rules apply |
| Lifetime annuity | Pot buys guaranteed income | Income taxable; tax-free cash may be taken first | A non-decreasing lifetime annuity normally does not trigger |
| Small-pot lump sum | Qualifying pot of no more than £10,000 | Usually 25% tax free and 75% taxable | Does not trigger if statutory small-pot conditions are met |
Defined benefit pensions work differently because they promise scheme income rather than exposing a personal investment pot. Taking a commencement lump sum can reduce the annual pension under scheme rules. Transfer and access decisions can carry advice requirements and irreversible trade-offs, so this guide focuses mainly on defined contribution tax mechanics.
How taxable pension withdrawals enter Income Tax
The taxable portion is added to other taxable income in the tax year from 6 April to 5 April. It can use remaining Personal Allowance, fill the basic-rate band, push income into higher or additional rates, and reduce the Personal Allowance once adjusted net income exceeds £100,000. Scotland uses Scottish pension income rates and bands for Scottish taxpayers.
Pension income is not subject to employee National Insurance. That does not make it tax free: PAYE is normally operated by the pension provider on taxable payments, and the final annual liability depends on all income together.
Worked example 1: £40,000 withdrawal with £20,000 other income
| Step | Calculation | Amount |
|---|---|---|
| Gross withdrawal | Given | £40,000 |
| Tax-free portion | 25% | £10,000 |
| Taxable pension portion | 75% | £30,000 |
| Total income | £20,000 + £30,000 | £50,000 |
| Tax before withdrawal | Tax on £20,000 | £1,486 |
| Tax after withdrawal | Tax on £50,000 | £7,486 |
| Tax attributable to withdrawal | £7,486 - £1,486 | £6,000 |
| Net withdrawal after final tax | £40,000 - £6,000 | £34,000 |
This assumes the full standard Personal Allowance, no other reliefs or deductions, and all income in one 2026/27 tax year. The effective tax on the £40,000 withdrawal is 15%, even though the taxable portion is charged at 20%, because £10,000 is tax free.
Worked example 2: taking £80,000 at once or £40,000 in each of two tax years
| Approach | Tax-free cash | Taxable pension | Extra tax caused by withdrawals | Net pension cash |
|---|---|---|---|---|
| £80,000 in one year | £20,000 | £60,000 | £21,946 | £58,054 |
| £40,000 in each of two years | £20,000 total | £60,000 total | £19,892 total | £60,108 total |
| Illustrative difference | Same | Same | £2,054 less | £2,054 more |
The two-year approach keeps less taxable pension in the higher-rate band in this specific example. It assumes the same tax bands and £40,000 other income in both years, no investment change, no provider charge and enough tax-free allowance. It is an illustration, not a forecast or recommendation.
Why first withdrawals are often emergency-taxed
When a provider makes a first flexible payment without a current tax code, PAYE may use an emergency code on a Month 1 basis. That gives the payment only one month's share of the Personal Allowance and tax bands, as if the same amount might be paid every month. A large one-off withdrawal can therefore be taxed far above the final annual liability.
The deduction is not a special pension penalty. It is provisional PAYE. HMRC can issue a code for later payments, reconcile after the tax year, or process an in-year reclaim where the conditions are met. Compare the provider's payment statement with the annual calculation, not just 25% of the gross amount.
P55, P53Z and P50Z: choosing the refund route
| Form | Typical situation | Important distinction |
|---|---|---|
| P55 | Part of a pot taken and no further flexible payments expected that tax year | Pot has not been emptied |
| P53Z | Whole pot emptied and you have other PAYE or pension income | Other income continues |
| P50Z | Whole pot emptied and you stopped working or have no continuing PAYE income | No continuing relevant PAYE source |
| P53 | Certain small pension lump sums | Not the standard flexible-access route |
Use HMRC's online guidance rather than selecting a form only from this table. Whether the pot was emptied, whether another payment is expected, residence status and ongoing income can change the route. Keep the P45 or payment statement from the provider.
The Money Purchase Annual Allowance
The standard Money Purchase Annual Allowance is £10,000 for 2026/27. Once triggered, it limits tax-relieved contributions to defined contribution arrangements and includes employer contributions. Carry forward cannot normally increase the MPAA. The provider should issue a flexible-access statement, and the individual must tell other active pension schemes within the required period.
Taking taxable flexible income normally triggers the MPAA. An UFPLS does so even though part is tax free. Taking only a pension commencement lump sum and leaving the taxable drawdown fund untouched normally does not. HMRC also lists exceptions including qualifying small-pot lump sums and certain non-decreasing lifetime annuities.
If you plan to keep contributing, confirm the exact payment type before withdrawing. The pension carry forward calculator can illustrate allowances, but it cannot decide whether a historic event legally triggered the MPAA.
State Pension and other pension income
The State Pension is taxable, but tax is not normally deducted from the payment itself. HMRC may collect the tax through another private-pension or employment tax code. When modelling a withdrawal, include the taxable State Pension due in the same tax year, not merely the amount received after any separate adjustment.
Annuity and occupational pension income also uses PAYE. Multiple providers can each hold a tax code, so check that allowances have not been duplicated or omitted. A year with employment ending, State Pension beginning and flexible withdrawals can need an HMRC reconciliation.
Questions to answer before requesting a withdrawal
- How much Lump Sum Allowance remains after all previous pensions?
- Will the payment be pension commencement cash, UFPLS, taxable drawdown or a small-pot lump sum?
- What other taxable income will arise before 5 April?
- Will the withdrawal enter a higher band or reduce the Personal Allowance?
- Could it trigger the MPAA while contributions are still being made?
- Will the provider use an emergency code, and which refund route would apply?
- Would a staged withdrawal change tax, benefits, investment risk or provider charges?
- Is regulated advice or a Pension Wise appointment appropriate before an irreversible decision?
Pension access affects longevity risk, investment exposure, means-tested benefits and estate planning as well as tax. This guide and calculator explain arithmetic, not suitability. The Pensions calculators hub links the withdrawal, carry-forward and contribution tools.
