What Is a Bypass Trust?
A bypass trust — sometimes called a spousal bypass trust or pension death benefit trust — is a discretionary trust that is set up to receive pension death benefits on behalf of your family. Instead of paying pension death benefits directly to your spouse or children, the pension scheme pays them into the trust. The trustees then distribute funds to the beneficiaries according to the trust deed.
The primary purpose of a bypass trust was to keep pension death benefits outside the estate of the surviving spouse. Without a trust, if your spouse inherited your pension as a lump sum and then died, the lump sum would form part of their estate and could be subject to inheritance tax at 40%. A bypass trust prevented this by holding the funds in a separate legal structure.
Why Bypass Trusts Were Popular Before 2015
Before the pension freedoms of April 2015, the tax treatment of pension death benefits was much less generous than it is today. If a pension holder died at 75 or over, any lump sum death benefit was taxed at a punitive 55%. This made bypass trusts an attractive option because:
- Pension lump sums paid before age 75 were tax-free, but would enter the surviving spouse's estate if paid directly
- A bypass trust kept the lump sum outside both the deceased's and the surviving spouse's estates
- The trust could distribute funds to the spouse (and others) as needed, without the funds being counted as part of anyone's estate
- The 55% tax on lump sums at 75+ made it important to extract pension funds as early and tax-efficiently as possible
How the 2015 Pension Freedoms Changed Everything
The pension freedoms introduced in April 2015 dramatically changed the tax treatment of pension death benefits, making bypass trusts unnecessary for most people. The key changes were:
| Feature | Before April 2015 | After April 2015 |
|---|---|---|
| Tax on lump sum death benefit (death before 75) | Tax-free | Tax-free |
| Tax on lump sum death benefit (death at 75+) | 55% tax charge | Beneficiary's marginal income tax rate |
| Beneficiary drawdown available | No (limited options) | Yes — any beneficiary can use drawdown |
| IHT on pension death benefits | Outside estate | Outside estate (until April 2027) |
The introduction of beneficiary drawdown was the game-changer. Instead of taking a lump sum (which would enter someone's estate), beneficiaries can now keep inherited pension funds within the pension wrapper indefinitely. The fund remains outside their estate for IHT purposes, grows tax-free, and they can withdraw income as needed. This achieves everything a bypass trust was designed to do, but without the cost and complexity.
When Bypass Trusts Might Still Be Relevant
While bypass trusts are no longer needed for most pension holders, there are limited scenarios where they may still serve a purpose:
- DB pension lump sums — if a DB scheme pays a lump sum death benefit (for example, a death-in-service payment), and the beneficiary does not want the money to enter their estate, a bypass trust could receive it
- Protecting vulnerable beneficiaries — if a beneficiary lacks the capacity to manage a large sum, a trust can provide a structure for professional management
- Protecting against creditors or divorce — funds in a discretionary trust may be better protected from creditors or divorce proceedings than funds paid directly to a beneficiary
- Multi-generational planning — where a provider does not offer successor beneficiary nominations, a trust could ensure the pension death benefits reach grandchildren
The April 2027 IHT Changes: Could Bypass Trusts Return?
From April 2027, unused pension funds will be brought within the scope of inheritance tax. This change fundamentally alters the calculus that made bypass trusts unnecessary after 2015. If pension death benefits are now subject to IHT, there may be scenarios where a trust structure helps reduce the overall tax burden.
However, it is too early to say definitively whether bypass trusts will become useful again. The details of the 2027 rules have not been finalised, and the government may introduce specific provisions that address the interaction between pensions, trusts, and IHT. Key questions that remain include:
- Will pension death benefits paid into a trust still be treated as part of the deceased's estate for IHT?
- Will there be specific anti-avoidance rules targeting the use of trusts to shelter pension death benefits?
- How will the double taxation relief work when both IHT and income tax apply?
Disadvantages of Bypass Trusts
Even in scenarios where a bypass trust could theoretically help, the disadvantages are significant:
- Setup costs — a solicitor will typically charge £1,000 to £3,000 to draft a bypass trust deed
- Ongoing administration — the trust must file tax returns, maintain accounts, and comply with HMRC's trust registration service
- Ten-year periodic charges — discretionary trusts face a potential IHT charge of up to 6% on the trust value every ten years
- Exit charges — when funds are distributed from the trust, an IHT exit charge may apply
- Income tax at trust rates — income and gains within a discretionary trust are taxed at 45% (income) and 28% (capital gains on property) or 20% (other gains), which are higher than most individuals' rates
- Loss of pension tax advantages — once pension funds leave the pension wrapper and enter a trust, they lose the tax-free growth, tax-free lump sum, and other pension tax benefits
- Complexity — trusts add a layer of legal and administrative complexity that most families would prefer to avoid
What to Do with an Existing Bypass Trust
If you have an existing bypass trust that was set up before 2015, you should review whether it still serves a useful purpose. In many cases, the trust may no longer be necessary because beneficiary drawdown provides the same IHT protection without the costs and complexity. However, you should not wind up a trust without professional advice, as there may be tax consequences.
Key considerations for existing bypass trusts include:
- Whether the trust is still holding significant assets
- Whether the beneficiaries' circumstances have changed since the trust was established
- The tax cost of distributing trust assets to beneficiaries
- Whether the upcoming 2027 IHT changes might make the trust useful again
Alternatives to Bypass Trusts
For most people, the following alternatives provide similar or better protection without the drawbacks of a bypass trust:
- Beneficiary drawdown — keeps pension funds in the pension wrapper, outside the beneficiary's estate, with flexible income access
- Expression of wish forms — ensure your pension goes to the right people without the need for a trust
- Life insurance in trust — a whole-of-life policy written into a trust can provide a lump sum to cover any IHT liability, without the complexity of a pension bypass trust
- Lifetime gifting — using your annual IHT exemptions to reduce the overall size of your estate
