Benefit Crystallisation Event: Triggers, Allowances, and Tax

A benefit crystallisation event is the point at which your UK pension benefits are measured against statutory tax limits. It happens when you access your pension in certain ways, or when lump sum death benefits are paid out after you die. Since 6 April 2024 the test has been reframed: the lifetime allowance was abolished under the Finance Act 2024, and these checkpoints, now called relevant benefit crystallisation events (rBCEs), measure the lump sum element of your benefits against two fixed allowances rather than the entire capital value of your pension against one overall cap.¹

What Changed on 6 April 2024

For nearly two decades every pension access was tested against a single lifetime allowance. The lifetime allowance charge was removed from 6 April 2023, and the allowance itself was abolished a year later. In its place, two fixed allowances now govern how much tax-free cash you can take across your lifetime and how much can pass to your beneficiaries as tax-free lump sum death benefits.¹

The old regime had thirteen numbered BCEs, each triggered by different actions such as taking a lump sum, entering drawdown, buying an annuity, reaching age seventy-five, or paying out death benefits. The new system replaces most of those with rBCEs that test only the lump sum element.² The practical effect matters. Under the old rules, designating funds into drawdown used up lifetime allowance even when you took no cash. Under the current rules, the focus is squarely on tax-free cash, so moving money into drawdown no longer consumes your allowances in the same way.

What Triggers a Relevant Benefit Crystallisation Event

The most common trigger is a pension commencement lump sum, the tax-free cash you can take when you start drawing a pension. You can normally withdraw up to twenty-five percent of the pot being accessed without paying income tax, subject to your remaining lump sum allowance.¹ Taking an uncrystallised funds pension lump sum, where you withdraw a whole pot in one go with twenty-five percent tax-free and the rest taxed as income, also counts.

Other triggering payments include serious ill-health lump sums and the various lump sum death benefits: uncrystallised funds, drawdown pension fund, annuity protection, flexi-access drawdown, and defined benefits lump sum death benefits.¹ Where a death benefit lump sum is paid, the deceased member’s legal personal representative reports any amount exceeding the available allowances to HMRC.

Serious Ill-Health Lump Sums

If a registered medical practitioner confirms in writing that you are expected to live less than one year, you can take a serious ill-health lump sum. There is no minimum age. The payment must extinguish all your uncrystallised rights under the arrangement. If you are under seventy-five, the lump sum is tax-free up to your available lump sum and death benefit allowance; anything above that is taxed as pension income at your marginal rate.³

How Your Benefits Are Valued

Measurement depends on the type of scheme. For defined contribution (money purchase) pensions the calculation is straightforward: the scheme administrator uses the market value of the assets in your pot at the point you access them. That figure is what the allowances are tested against.

Defined benefit schemes promise a guaranteed income rather than holding a pot. Under the old lifetime allowance regime, the annual pension was multiplied by a valuation factor of twenty to one, with any separate scheme lump sum added on top. Schemes offering annual increases above five percent could apply to HMRC for a higher scheme-specific factor. Under the current rules, rBCE testing focuses on the lump sum element rather than the capitalised value of the income stream, so that twenty-to-one multiplier is less central than it once was.

The Two Allowances That Now Apply

The Finance Act 2024 introduced two fixed figures. Your lump sum allowance (LSA) is £268,275. This is the maximum tax-free cash you can take across all your pensions during your lifetime, and every pension commencement lump sum or tax-free element of a UFPLS reduces it.⁴

Your lump sum and death benefit allowance (LSDBA) is £1,073,100. It is a broader cap covering both the tax-free lump sums you take in your lifetime and any lump sum death benefits paid to your beneficiaries. Tax-free lump sums you take also count toward this combined figure, so the LSDBA acts as an overall ceiling.⁴

Both figures can be higher if you hold a valid protection from the old regime, such as Individual Protection 2016, Fixed Protection 2016, or earlier protections. The standard figures apply to everyone else.⁵

Tax on Amounts Above the Allowances

When a lump sum takes you past your available LSA or LSDBA, the excess loses its tax-free status and is taxed as pension income at your marginal rate.⁶ Depending on your total income for the year that could mean twenty, forty, or forty-five percent on the excess.

If your LSA is already used up, a scheme can still pay tax-free cash as a “pension commencement excess lump sum,” but the whole excess is subject to income tax, deducted by the administrator before the money reaches you.¹ Because these amounts are often large, they can push you into a higher band for the year. The same principle applies to death benefit lump sums: any amount above the deceased member’s remaining LSDBA is taxed at the recipient’s marginal rate.

Transitional Rules for Pre-April 2024 Benefits

If you used some or all of your lifetime allowance before 6 April 2024, transitional rules work out how much of the new allowances remain. Broadly, the percentage of lifetime allowance you previously used is converted into a deduction from your LSDBA. If your scheme has issued you a transitional tax-free amount certificate, the specific amount on that certificate is deducted instead.²

If you registered for Fixed Protection 2016 or Individual Protection 2016 before the old regime ended, you may have higher allowances than the standard figures. To use them, give your scheme two reference numbers: your protection notification number and your scheme administrator reference. Both are available by signing in to the HMRC pension protection service online.⁷

One trap worth flagging. Fixed Protection 2016 holders who registered after 15 March 2023 can still lose their protection by making new pension contributions, starting a new arrangement, or being automatically enrolled into a workplace scheme. Those who registered by 15 March 2023 and held valid protection on 6 April 2023 are safe. Automatic enrolment catches people out here, so confirm your registration date if this affects you.

Reporting and Statements

After an rBCE, your scheme administrator must issue a relevant benefit crystallisation event statement showing how much of your LSA and LSDBA has been used. If you are receiving a pension from the scheme, the statement must be provided at least once per tax year. Otherwise it must be issued within three months of the rBCE.⁸

You also have to tell each of your schemes about any rBCEs that have already happened with other providers. Without that history, an administrator cannot calculate your remaining allowances correctly and could pay out too much tax-free cash, leaving you with an unexpected bill.

What This Does Not Cover

The lump sum allowances cap what you take out. They are separate from the annual allowance, which caps what goes in. For 2026/27 the standard annual allowance is £60,000, tapering by £1 for every £2 of adjusted income above £260,000, down to a floor of £10,000 at £360,000.⁹ Once you flexibly access your pension, your allowance for further money purchase contributions drops to £10,000 under the money purchase annual allowance. Triggers include taking income from flexi-access drawdown, taking a UFPLS, or exceeding the income cap on a pre-existing capped drawdown fund. Taking only tax-free cash does not trigger it, and defined benefit accrual is dealt with under separate rules.

Overseas transfers are a separate matter too. Moving benefits to a qualifying recognised overseas pension scheme carries a twenty-five percent overseas transfer charge unless a specific exemption applies. A transfer to a scheme that does not qualify as a QROPS is treated as an unauthorised payment with harsher charges, so the classification is worth confirming before you initiate the transfer.¹⁰
