Start with the purpose and the beneficiaries
This guide concerns a proposed lifetime transfer into an ordinary UK discretionary family trust, using guidance checked on 7 November 2026. Special trusts, overseas connections and relief-bearing business or agricultural assets require separate analysis. Decide why trustees need discretion, who may benefit and what resources the donor must retain before selecting the asset.
Compare an outright gift as well as a trust. Flexibility brings trustee responsibilities, professional costs and potentially different tax treatment. A trust is not automatically the lowest-tax route.
IHT: chargeable does not necessarily mean tax payable now
A lifetime transfer into a discretionary trust is generally an immediately chargeable transfer under the IHT framework. Review the loss to the donor’s estate, earlier chargeable transfers, available nil-rate band and any exemptions or reliefs. Funding within the available band is not the same as exemption from the relevant-property regime.
Where entry tax is payable, who bears it affects the calculation: tax paid by the donor can increase the loss to their estate. Consider potential additional liability on death within seven years and the trust’s future ten-year and exit charges. Do not treat survival for seven years as ending every trust tax obligation.
CGT: transferring investments is a separate disposal
Ordinary sterling cash has no embedded investment gain to transfer. An investment asset can have one: a gift normally brings market value into the CGT computation. TCGA 1992 section 260 can provide hold-over relief for a qualifying chargeable transfer, including certain transfers where no IHT is actually payable. It is not automatic and does not apply merely because the document is called a trust deed.
Relief defers the qualifying gain by reducing the recipient’s acquisition cost. It does not erase the gain. A claim is required; consideration received and the detailed statutory restrictions can change the result. A potentially exempt transfer does not qualify under this particular route, although other relief provisions may need separate consideration.
Hypothetical comparison: equal value, different latent gains
Assume a donor is comparing £200,000 sterling cash with an unencumbered investment holding worth £200,000 that cost £80,000. Ignore transaction costs and assume the whole holding is transferred. The investment route has a £120,000 gain before relief; the cash route does not have that embedded investment gain.
If the entire £120,000 qualifies for section 260 relief and a valid claim is made, the trustees’ illustrative acquisition cost becomes £80,000 rather than £200,000. A later sale at £200,000 would therefore still expose that deferred gain, before any other adjustments. This example assumes relief eligibility solely to show the mechanism. It does not establish IHT neutrality, eligibility or an actual tax saving, and is not a client case.
Retained benefits can undermine the intended outcome
TCGA 1992 section 169B restricts hold-over relief for settlor-interested settlements, subject to exceptions. The test extends beyond simply excluding the donor personally. Review the permitted beneficiaries, including relevant family members, and any arrangements for a later benefit. HS295 explains the exclusion and potential clawback if the trust becomes settlor-interested after funding.
Separately, keeping a benefit can engage IHT gift-with-reservation rules. Income attribution also needs its own review. Do not assume one exclusion clause settles every tax test. Mortgaged property introduces further debt, lender and land-transaction-tax questions beyond this cash/investment comparison.
Sequence the deed, valuation, claims and administration
Agree the objective with tax and legal advisers, review the donor’s gift history and retained resources, model the funding options and stress-test trustee cash needs. Settle beneficiary exclusions and powers before execution. Obtain the required valuations, complete the transfer, and make the necessary claims and returns. Check registration and continuing reporting obligations even where no immediate tax is due.
