The Double Whammy — What Finance Act 2026 Actually Does to Your Clients’ Pensions

For three decades, unused defined contribution pension funds were the most efficient asset in an estate. No IHT on death. No income tax if the member died before 75. A modest income tax charge if they died after 75, but one that could be managed through nomination and careful drawdown. The pension fund was, in planning terms, the last asset you touched.

Finance Act 2026 has changed all of that. From April 2027, residual DC pension funds enter the IHT estate. And for clients over 75, a second tax — income tax — hits the beneficiaries on every pound they withdraw. Two taxes, hitting the same money, simultaneously. The so-called Double Whammy.

What the law actually says

Finance Act 2026 received Royal Assent on 20 March 2026. The legislation amends the Inheritance Tax Act 1984 to bring unused pension death benefits within the chargeable estate of the deceased. This applies to:

• Defined contribution pensions — SIPPs, personal pensions, workplace DC schemes
• Death benefits from pension drawdown funds
• Pension death benefits that have not been crystallised

It does not apply to defined benefit pension schemes, annuities in payment, or pension income already drawn. The change takes effect from 6 April 2027. There is no transitional relief, no grandfather provision, and no further Parliamentary opportunity to reverse it. The major political parties are not opposing it.

The mathematics of the Double Whammy

Consider a client over 75 with a £500,000 SIPP. They die in May 2027. Their two children are the nominated beneficiaries. One child pays income tax at 45%.

In extreme cases — where the pension fund pushes the estate above the nil-rate band and the RNRB is unavailable, or where the beneficiary also has substantial other income — the effective combined rate can reach 80% or higher.

Who is affected and when

Clients over 75 — act now. For this group, the income tax charge on pension death benefits is not new — it has applied since 2015. What is new from April 2027 is IHT. But here is the crucial planning point: a client who transfers their pension fund into the right structured solution today can eliminate the income tax charge immediately from day one of transfer, and simultaneously start a 2-year qualifying clock for IHT relief. There is no reason to wait.

Clients under 75 with non-spouse beneficiaries — act before April 2027. For these clients, income tax on death does not currently apply. But IHT will from April 2027. The planning window is now. The structured IHT solution requires a 2-year qualifying period. That clock needs to start before April 2027 to be fully effective when the legislation takes effect.

Clients with spousal beneficiaries. The spousal exemption covers IHT on the first death. But on the second death — when the pension passes to children — the full charge applies. The Double Whammy is not eliminated by spousal exemption; it is deferred.

The executor problem

There is a secondary consequence that has received less attention: executor personal liability. Under the new rules, the executor is personally responsible for paying the pension IHT to HMRC within six months of death — before the estate is distributed. For a £500,000 pension, that is £200,000 of personal liability falling on the executor, often a child, before they receive anything themselves.

What advisers should do now

The immediate action is to audit your client bank. Any client with a DC pension balance above £100,000, over age 55, with children or non-spouse beneficiaries as intended recipients, should be reviewed before April 2027. For clients over 75, the case for acting is urgent — the income tax saving from the right solution is immediate and the IHT clock starts from the day of transfer.

There is a structured solution available — the Flexible Pension Annuity (FPA) — which eliminates income tax on death benefits from day one via a Preference Share mechanism, and eliminates IHT after a 2-year qualifying period via Business Property Relief (s105(1)(bb) IHTA 1984). It is FCA-regulated, FSCS-protected at 100% with no cap, available on ORIGO, and has a 100% BPR claim success rate across 250+ HMRC claims to date.
