Gifting a Buy-to-Let Property: CGT, Inheritance Tax and What You Need to Know

Gifting a buy-to-let property can take its value outside your estate for inheritance tax once you survive seven years, but the gift is treated as a sale at market value, so capital gains tax is usually payable straight away. That trade-off sits at the heart of inheritance tax property portfolio UK planning: a known CGT bill now against a possible 40% charge later. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, helps landlords model both sides before anything is signed. This article covers CGT on a gifted rental, the seven-year rule, why keeping the rent defeats the gift, trusts and Business Property Relief, and a worked example.

Key Takeaways

• A gift of a buy-to-let property to anyone other than a spouse or civil partner is treated as a disposal at market value for capital gains tax.
• Capital gains tax on residential property is charged at 18% within the basic rate band and 24% above it in 2026/27, after a £3,000 annual exempt amount.
• UK residential property gains must be reported and the tax paid within 60 days of completion.
• An outright gift of property to an individual is a potentially exempt transfer that leaves the estate entirely if the donor survives seven years.
• The inheritance tax nil rate band is £325,000 and the rate above it is 40%, with both thresholds frozen until April 2031.
• The £2.5 million Business Property Relief allowance from 6 April 2026 does not normally cover rental portfolios, because letting is treated as an investment activity.

What capital gains tax is due when you gift a buy-to-let property?

Capital gains tax is due on a gifted buy-to-let property because a gift to a connected person, such as a child, is treated as a sale at full market value. The gain is market value at the date of the gift less the original cost and capital costs, even though no cash is received.

In 2026/27, the gain above the £3,000 annual exempt amount is taxed at 18% to the extent it falls within your remaining basic rate band and 24% above it. The tax must be paid within 60 days, so the cash has to come from elsewhere. Our article on the 60-day reporting rule sets out the process.

Gift holdover relief is not available on an outright gift of let residential property, because it is not a business asset. Gifts between spouses and civil partners pass at no gain and no loss, so rebalancing ownership within a marriage is a useful first step.

How does the seven-year rule affect inheritance tax on a gifted property?

An outright gift of property to an individual is a potentially exempt transfer, which falls out of your estate for inheritance tax if you survive seven years. If you die within seven years, the gift is added back and uses your £325,000 nil rate band first.

Where the failed gift exceeds the available nil rate band, inheritance tax at 40% is due on the excess, reduced by taper relief when death occurs between three and seven years after the gift. The recipient is primarily liable for that tax, so families often arrange life cover written in trust.

A buy-to-let property never qualifies for the £175,000 residence nil rate band, which applies only to a home you lived in, passing to direct descendants. Large landlords also lose the residence nil rate band on their own home through the taper above £2,000,000, which makes buy-to-let inheritance tax planning more urgent as a portfolio grows.

Why does keeping the rental income cancel the inheritance tax benefit?

Keeping the rent after gifting a property is a gift with reservation of benefit, and the property stays in your estate for inheritance tax as if no gift had been made. The rule sits in section 102 of the Finance Act 1986.

The capital gains tax charge still applies to the gift, so a landlord who keeps the income can pay CGT on the transfer and inheritance tax on the same property later. For the gift to work, the recipient must receive the rent and pay the tax on it. Our guide to inheritance tax planning for property portfolios covers the alternatives for landlords who still need the income.

Can trusts or Business Property Relief cut inheritance tax on a property portfolio?

Business Property Relief rarely helps an IHT landlord, because a business consisting wholly or mainly of holding investments is excluded, and HMRC and the courts treat ordinary letting as investment. The £2.5 million relief allowance from 6 April 2026 is therefore unlikely to apply.

A trust is the main buy-to-let inheritance tax planning alternative where the family wants control retained. A gift into a discretionary trust is a chargeable lifetime transfer rather than a potentially exempt transfer, so an immediate inheritance tax charge arises on value above the available nil rate band, and periodic charges follow every ten years. The advantage is that gift holdover relief is available on a transfer into such a trust, deferring the capital gains tax until the trustees sell. For many couples, gifting property within the nil rate band into trust every seven years is an efficient pattern.

Worked example: gifting a flat to an adult child

Gifting a rental flat bought for £150,000 and now worth £350,000 produces a capital gains tax bill of £47,280 for a higher rate taxpayer, against a potential inheritance tax saving of £140,000 if the parent survives seven years.

The gain is £200,000. After the £3,000 annual exempt amount, £197,000 is taxed at 24%, giving £47,280, payable within 60 days. Assuming the rest of the estate already uses the nil rate band, keeping the flat until death would cost £140,000 in inheritance tax at 40%, although the CGT gain would then be wiped out by the uplift to market value on death. If the gift succeeds, the net saving is £92,720.

There is usually no stamp duty on a gift, but if the child takes over a mortgage, the debt assumed counts as consideration. Our article on stamp duty on family transfers explains the calculation.

Frequently Asked Questions

Do I pay capital gains tax if I gift a buy-to-let property to my children?

Yes. Gifting a buy-to-let property to your children is treated as a sale at market value, so capital gains tax is due on the gain even though no money changes hands. In 2026/27 the gain above the £3,000 annual exempt amount is taxed at 18% or 24%, and must be reported and paid within 60 days of completion.

How long do I have to live after gifting a property to avoid inheritance tax?

You must live for seven years after gifting a property to an individual for the gift to fall completely outside your estate for inheritance tax. The gift is a potentially exempt transfer. If you die within seven years, it is brought back into account against your £325,000 nil rate band, and tax at 40% can arise on any excess.

Can I gift a rental property and keep the rental income?

No. If you gift a rental property but keep receiving the rent, HMRC treats it as a gift with reservation of benefit and the property stays in your estate for inheritance tax. The CGT charge on the gift still applies, so you can pay CGT now and inheritance tax later on the same property.

Does Business Property Relief apply to a buy-to-let portfolio?

Business Property Relief does not normally apply to a buy-to-let portfolio, because letting property is treated as holding investments. The £2.5 million 100% relief allowance from 6 April 2026 is therefore rarely available to landlords, so planning relies on lifetime gifts, trusts and the nil rate band.

Conclusion

Gifting a buy-to-let property swaps an uncertain 40% inheritance tax charge for a certain capital gains tax bill today, and it only works if you survive seven years and give up the rent. For an IHT landlord with a growing portfolio, a well-timed gift can save tens of thousands of pounds. Model the CGT, the seven-year exposure and any mortgage before transferring anything, and make sure the recipient, not you, receives the rent from the date of the gift. Spousal transfers first, then gifts to children or a trust, is often the most efficient order.
