Why gifting a rental property can bring a tax bill approaching 64%

Giving a property to the children can trigger capital gains tax and still leave an inheritance tax bill if the donor dies within seven years. For married couples, transferring an asset with a large accumulated gain to a terminally ill spouse can sometimes produce a very different result.

Landlords often reach a point where the priority becomes making life easier for the family. They want to reduce their responsibilities, provide for a spouse and pass on the wealth they have spent years building. Giving a property to the children can seem a sensible way to start.

The difficulty is that capital gains tax and inheritance tax have different rules. A gift can bring the first tax into charge immediately while failing to remove the second. Understanding that interaction also explains one of the most counterintuitive aspects of estate planning: why a couple might transfer an asset into the ownership of the spouse who is expected to die first.

A gift can create a tax bill without producing any cash

When you give an investment property to an adult child, the normal capital gains tax calculation uses its market value at the date of the gift. Receiving no money does not prevent a taxable disposal. Broadly, the gain is that value less the allowable acquisition cost, qualifying improvements and other permitted costs.

The higher CGT rate is currently 24%. An ordinary buy-to-let investment gifted outright to a child does not generally qualify for business asset gift hold-over relief, which defers a gain. There are reliefs for particular circumstances, but being a landlord is not, by itself, enough.

How the combined bill can approach 64%

Consider a hypothetical mortgage-free rental property worth £1 million, with an allowable CGT cost of £50,000. Assume the donor has used their CGT annual exemption, has no available losses or other reliefs, pays CGT at 24% and bears that tax personally from other funds. Earlier gifts have already exhausted all available inheritance tax nil-rate band and gift exemptions.

The landlord gives the property outright to a child, retains no benefit and dies two years later. Assume its value has not fallen and there are no other relevant reliefs.

Why the total can approach 64%: as the allowable cost becomes smaller relative to the property’s value, the combined figure approaches 64%. CGT applies to the gain, while inheritance tax applies to the taxable value of the gift. The two rates apply to different amounts, so this is not a flat 64% charge on every property gift.

These are also bills falling on different people. The donor normally pays CGT; the recipient is normally primarily liable for inheritance tax on a taxable failed gift. A property received without cash can therefore leave the child needing to fund a substantial liability.

The calculation needs to cover the whole family estate. Paying CGT from the donor’s other funds can reduce the estate remaining at death. If the recipient bears the CGT, a specific deduction can reduce the gift’s inheritance tax value. The £628,000 is a gross total of the two bills in this example, rather than a calculation of the additional cost compared with keeping the property.

The seven-year rule needs careful explanation

An outright gift to a child is usually a potentially exempt transfer. Death within seven years can make it chargeable, but does not automatically create a 40% bill on the entire gift. Earlier gifts and available allowances matter.

Where inheritance tax is payable, taper relief reduces the tax after three years. The usual rates on the taxable part are:

Taper relief reduces tax on a chargeable gift; it does not progressively reduce the gift’s use of the nil-rate band. Keeping the benefit of a gifted property, such as its rental income, can also engage the gift-with-reservation rules, so simply waiting seven years may not solve the problem.

Death changes the capital gains tax calculation

The treatment of an asset still owned at death is different. Under section 62 of the Taxation of Chargeable Gains Act 1992, there is generally no CGT charge on death and the person inheriting acquires the asset at its market value at that date. The accumulated lifetime gain is effectively removed from the future CGT calculation.

For an outright lifetime gift, the donor’s later death does not normally give the child another CGT uplift. The property already belongs to the child, even though the earlier gift can become chargeable to inheritance tax. That distinction is why the timing and direction of a transfer matter so much.

The counterintuitive transfer to a dying spouse

Now consider a married couple. One spouse owns a property with a substantial unrealised gain, sometimes described as an asset “pregnant with capital gains”. The other spouse has a terminal illness. Their concern is how the survivor will fund life and manage the portfolio after bereavement.

Assume both are UK resident and long-term UK resident for inheritance tax purposes, their marriage has not broken down, and the property is mortgage-free. The healthy spouse transfers genuine beneficial ownership to the terminally ill spouse. Under the inter-spouse CGT rules, this can take place at no gain and no loss: the recipient takes over the original tax cost.

The recipient then owns the asset until death and leaves it back to the surviving spouse under their will. The inherited asset acquires its date-of-death market value as its new CGT cost. The spouse exemption can cover both transfers for inheritance tax. The same principles apply to civil partners, but not automatically to unmarried couples.

Suppose the property originally cost £100,000 and is worth £500,000 at death. Without this planning, a sale by the original owner at £500,000 would produce a £400,000 gain, potentially costing £96,000 at 24%, before allowances, losses and costs. After inheriting it back with a £500,000 CGT cost, a sale at the same value would produce no gain on those simplified figures. A later rise in value could still be taxable.

The practical benefit is greater freedom to sell, repay borrowing elsewhere or simplify the portfolio. An exempt spouse transfer does not require seven years’ survival. However, the asset is now in the survivor’s estate, so their own eventual inheritance tax position still needs attention.

Beneficial ownership is what matters

For property in England and Wales, the registered legal owner and beneficial owner can be different. Beneficial ownership concerns the actual economic entitlement to the asset. HMRC recognises that a spouse can hold an asset on behalf of the other.

A lawyer may therefore be able to document a transfer of beneficial ownership while the registered title stays unchanged. The transfer must be legally effective and completed before death, with the income and capital entitlements properly addressed. The will must deal with the resulting ownership. A change of label, an uncompleted intention or a signature added afterwards cannot achieve the same result.

HMRC has published an example of this planning

Example D19 in HMRC’s General Anti-Abuse Rule guidance concerns investment-company shares gifted to a terminally ill wife and inherited back by her husband. HMRC acknowledges the tax-saving purpose and concludes that the GAAR would not apply on those facts.

It also considers a gift made on the day of death, reaching the same conclusion provided the wife had full capacity and the gift was validly completed beforehand. This supports the CGT principle explained here. The example concerns shares, however, and does not settle a property’s conveyancing, mortgage or land transaction tax requirements.

The details determine whether the result is available

Capacity, informed consent and the couple’s wishes come first. The lawyer needs to establish that the transfer and will arrangements are valid, and the advisers must consider what happens if the expected order of deaths changes. A lifetime transfer back simply carries forward the old CGT cost; it does not produce the uplift obtained on death.

Mortgaged property needs particular care. Transferring only the beneficial interest does not establish that lender consent is unnecessary. Taking responsibility for debt can also trigger SDLT in England or Northern Ireland. Wales and Scotland have their own land transaction taxes, and property law must be checked locally.

Residence history matters too. Since 6 April 2025, the spouse exemption can be restricted where a long-term UK resident transfers assets to a spouse who is not a long-term UK resident. Overseas taxes and succession rules may create additional consequences.

For a company-owned portfolio, the distinction between the shares and the properties is crucial. An uplift in inherited shares does not reset the company’s acquisition cost of the buildings. The company continues to own them and calculates its own gains when it sells.

Make the family decision in good time

Serious illness is a difficult setting for financial decisions. Reviewing ownership, wills and accumulated gains earlier gives both spouses more time to understand their options and decide what fits their wishes.

Before gifting a rental property, ask your advisers to compare the combined CGT and inheritance tax consequences of giving it away now, retaining it and reviewing ownership between spouses. Include the income you still need, the survivor’s ability to manage the assets, and how the family would fund each tax bill. A decision intended to help the next generation deserves that full calculation.
