Change the Owner, Not the Gain: Spousal Transfers Before a 2026/27 Sale

A capital gains tax bill is often decided before the sale contract is signed. For married couples and civil partners, the ownership of an investment can be rearranged ahead of a disposal, and the tax system generally treats a transfer between them as giving rise to neither a gain nor a loss. The result is not an exemption: the gain is deferred and follows the asset into the recipient’s hands. But the identity of the seller can matter a great deal, particularly where one partner has unused annual exempt amount, capital losses or lower taxable income.

What the no-gain, no-loss rule actually does

When assets are transferred between spouses or civil partners who are living together, the legislation treats the disposal as being made for a consideration that produces no gain and no loss. The transferor does not pay capital gains tax on the transfer. The recipient is treated as having acquired the asset at the transferor’s original base cost, and generally with the transferor’s original acquisition date. In effect, the recipient steps into the transferor’s shoes.

The gain is not erased. It is postponed until the recipient sells the asset to someone outside the marriage or civil partnership. If shares were bought for £10,000 and are worth £30,000 when transferred, no gain arises on the transfer. If the recipient later sells for £30,000, the £20,000 gain is assessed on the recipient, subject to the usual reliefs and exemptions.

This can be useful where the recipient has a lower marginal rate of income tax, unused capital losses, or an annual exempt amount that would otherwise go unused. It can also be useful where the transferor has already used their own annual exempt amount for 2026/27. What it cannot do is create a second exemption for the same gain. It changes the person who reports the gain, not the amount of the gain itself.

Why the order of events matters

A transfer must be genuine and must happen before the sale. For capital gains tax, the disposal generally occurs when an unconditional contract is made, not when completion takes place. If a sale has already been agreed, or if the transfer is arranged only after the buyer is committed, HMRC is likely to view the sequence as artificial. The transfer should be executed, and beneficial ownership should pass, before the sale contract is entered into.

The point is particularly important for shares and funds held on investment platforms. Some platforms do not permit transfers between spouses in specie, or they require a stock transfer form and a period of administration. A sale instruction given before the transfer is completed may mean the transferor remains the seller for tax purposes. For listed shares, the contract date and settlement mechanics should be checked carefully. For unlisted shares, the company’s articles and any shareholder agreement may also affect what is possible.

Both annual exempt amounts, but not twice for the same gain

For 2026/27, each individual has an annual exempt amount of £3,000 for capital gains tax. A no-gain, no-loss transfer does not use up the transferor’s annual exempt amount. When the recipient later sells, the recipient’s annual exempt amount can be set against the gain. If both spouses or civil partners have investments to sell, each can use their own £3,000 allowance on their own disposals.

The rate of tax also depends on the seller’s income. For 2026/27, capital gains tax on most investments is charged at 18% to the extent that gains fall within the seller’s available basic rate band, and 24% above it. A spouse with lower taxable income may therefore have more room at the 18% rate. That is often the real value of a pre-sale transfer, rather than the annual exempt amount alone.

The traps: genuine, permanent and properly documented

The relief is not available merely because two people are married. They must be married or in a civil partnership and living together at the time of the transfer. If they are separated, the no-gain, no-loss rule generally stops applying, and a transfer may be treated as a disposal at market value. That can crystallise a gain even though no money changes hands. Divorce or dissolution brings further complications, and the timing of the separation is therefore central.

The transfer must also be genuine. A paper exercise that leaves the transferor with control, use or benefit of the asset may be challenged. An outright gift, or a genuine transfer for consideration, is different from an arrangement where the transferor retains a beneficial interest. For shares, the stock transfer form, the company’s register and the platform records should all be consistent. For funds, the platform’s own transfer process should be followed. A dated record of the transfer, the value at transfer and the original acquisition cost should be kept.

Stamp duty and stamp duty reserve tax can also arise on share transfers, although nil consideration transfers between spouses often do not attract stamp duty. Broker charges and administrative requirements still apply. Where the asset is land or residential property, different rules and reporting obligations may apply, including the 60-day capital gains tax return for certain residential property disposals.

Losses need a separate thought

Where an asset stands at a loss, a no-gain, no-loss transfer preserves the loss for the recipient. That may be useful if the recipient has gains to offset. But it is not automatically the right move. If the transferor has gains elsewhere, selling the loss-making asset in the transferor’s own name may allow the loss to be set against those gains. The decision should be made asset by asset, not as a blanket strategy.

A pre-sale checklist for 2026/27

• Confirm that you are married or in a civil partnership and living together at the date of transfer.
• Identify who beneficially owns the investment. A joint holding may require only one share to be transferred.
• Establish the original acquisition cost, date and any allowable improvement or transaction costs.
• Check whether the asset has a gain or a loss, and whether the recipient has gains, losses or annual exempt amount to use.
• Compare the seller’s likely capital gains tax rate with the recipient’s rate, taking income and the basic rate band into account.
• Complete the transfer before an unconditional sale contract is made.
• Use the correct legal and platform formalities, and keep dated records of the transfer and valuation.
• Remember that a sale in 2026/27 will usually be reported through Self Assessment by 31 January 2028, with separate rules for certain residential property disposals.

A spousal transfer is a legitimate planning step when it reflects a real change in ownership and is carried out in the right order. It is not a substitute for advice on the wider position, particularly where separation, losses or residential property are involved. Handled carefully, it can ensure that the gain is taxed in the hands of the person best placed to deal with it.
