Can you take a small defined benefit pension as a lump sum?
Trivial commutation lets you take a small defined benefit pension as a one-off lump sum, with 25% tax free and the rest taxed as income, provided the total value of all your pension rights is £30,000 or less. The test is taken across everything you hold on a single nominated day, which is what most often disqualifies people who assumed only the small pension counted.
- The limit: £30,000 total across all pension rights, not per scheme.
- The test date: a single nominated date within three months of the first payment.
- The window: all trivial commutation payments must be made within twelve months.
- The tax: 25% tax free, the balance taxed as pension income, usually on an emergency code first.
01 The £30,000 test
Trivial commutation is available where the total value of all your pension rights is £30,000 or less. That includes defined benefit rights valued on a prescribed basis, defined contribution pots, and pensions already in payment — not just the small scheme you want to cash in.
The valuation is taken on a single nominated day, which must fall within three months before the first payment. Someone with a £14,000 defined benefit entitlement and a £40,000 SIPP does not qualify, however small the scheme pension is on its own.
This is different from the small pots rule, which tests a single arrangement rather than the whole picture. Small pots are the more flexible route where they apply, and they do not affect the annual allowance either.
02 How the payment works
You must be 55 or over, rising to 57 from April 2028. A quarter of the payment is free of Income Tax and the remainder is taxed as pension income at your marginal rate, usually with an emergency code applied to the first payment that then has to be reclaimed.
Once the first trivial commutation payment is made, a twelve-month window opens and every other trivially commuted pension has to be paid inside it. Missing that window does not undo the payment already made; it simply means the remaining pensions cannot use this route.
The scheme has to be willing to pay, which is not automatic. Trivial commutation is permitted by legislation rather than required of schemes, so the administrator's rules decide whether the option exists.

03 When it is worth doing
A very small scheme pension is often worth less than the administration around it. A £600-a-year pension generates an annual payslip, a P60, a tax code and a change-of-address obligation for thirty years, and its lifetime value may be under £15,000. Converting it to cash removes all of that.
Against that, a small index-linked pension with a survivor's benefit is still a guaranteed income, and the trivial commutation lump sum is taxed at your marginal rate above the 25%. Someone in a high-income year will lose more of it than someone taking it in a year with unused personal allowance, so timing the payment matters as much as the decision.
The other consideration is that taking it removes the scheme from your record permanently. There is no route back, and no residual entitlement for a survivor.
Shows: the net lump sum from a trivial commutation, and how many years of the pension it replaces after tax. Ignores: the £30,000 qualifying test, emergency tax on the payment, the survivor's pension, and inflation increases on the pension.
On the defaults above, the worked example shows £11,900. The net lump sum replaces about 19 years of the pension after tax, before any inflation increases on it.
Tiny pensions are worth less than they look and cost more than they should — not in money, in attention. Thirty years of statements, tax codes and address changes for six hundred pounds a year is a genuine cost, and trivial commutation is the tidy-up. Two cautions. Check the £30,000 test across everything you hold, not just the pension in front of you, because that is where most people fall out. And take the payment in a year when you have personal allowance spare, because the taxable three quarters is charged at your marginal rate and a bad year can cost you 40% of it.
FAQ
Does the £30,000 limit apply per scheme?
No. It is the total value of all your pension rights, including defined contribution pots and pensions already in payment, measured on a single nominated day within three months of the first payment.
How is trivial commutation different from the small pots rule?
Small pots tests one arrangement at a time against a £10,000 limit and ignores everything else you hold; trivial commutation tests all your pension rights against £30,000. Small pots is usually the more flexible route where it applies.
Do I have to take all my small pensions at once?
Within twelve months of the first trivial commutation payment. After that window closes the remaining pensions cannot use this route, though they may still qualify under the small pots rule if they are individually small enough.
