Two beliefs travel with property sellers: “my home is tax-free” and “I left the UK, so UK tax no longer applies”. Capital gains tax on property tests both, and each holds only inside conditions.
The tax falls on your gain, not on the sale price. What you owe turns on how you used the property, where it stands and where you live, and the deadline is counted in days. Property has rules of its own, set on top of the general capital gains tax rules and rates.
Often, but not always. Capital Gains Tax is charged on the gain, usually the difference between what you paid for the property and what you received on selling or otherwise disposing of it. Property dealers and developers sit outside it altogether: they pay Income Tax or Corporation Tax instead.
According to HMRC (August 2026), 205,000 taxpayers reported 230,000 disposals of residential property in the 2024 to 2025 tax year, for £12.9 billion of gains and £2.8 billion of Capital Gains Tax. Disposals are not properties: co-owners can each report their share of one sale.
| Inside the charge | Usually outside the charge |
|---|---|
| A property that is not your main home: buy-to-let property, business premises, land, inherited property | Your main home, where it meets the conditions set out below |
| A main home that has been let, used for business or is very large | The share of that gain the relief still covers |
Where the property stands in one country and you live in another, the same gain can mean tax in two countries on one sale.
Your home is the large exception. Under the Taxation of Chargeable Gains Act 1992, Private Residence Relief covers the gain on a dwelling-house that is, or has at any time in your period of ownership been, your only or main residence, with grounds up to a permitted area of 0.5 of a hectare. Relief is full where it was your only or main residence throughout, or throughout except for all or part of the last 9 months. GOV.UK lists five conditions for full relief to apply automatically:
When one condition fails, the relief is reduced, not necessarily lost. Some periods are then treated as occupation.
| Period | Length | Condition |
|---|---|---|
| Final period | Last 9 months; 36 months for a disabled person or a person in long-term residential care with no other home | Only or main residence at some point |
| Start of ownership | Up to the first 24 months | Home being built or renovated, or old home unsold |
| Absence for any reason | Up to 3 years in total | Main residence at a time before and a time after |
| Employment with all duties outside the UK | Any length | As above, or return prevented by the place of work |
| Work location or employer's requirement elsewhere | Up to 4 years | As above, or return prevented by the place of work |
Letting Relief applies only where you lived in the home at the same time as your tenants, never where the whole home was let for a time. It is the lowest of the Private Residence Relief, £40,000 and the gain made from the letting.
Married couples and civil partners can count only one main home at any one time. With two or more homes, the main residence can be nominated within 2 years of each change in the combination of homes.
A home in a country where you do not live follows a further rule. Since 6 April 2015, a tax year in which neither you nor your spouse or civil partner was resident in the country where the home stands counts as occupation only if 90 days were spent in the home that year. The days need not be consecutive, your spouse's days count, and the 90 days are reduced pro rata for a part year of ownership.
If you have left for the UAE or elsewhere and kept a former UK home, the years abroad may therefore count as occupation only if an absence in the table applies or the 90-day count is met; the last 9 months count in any event.
Private Residence Relief covers the gain on a dwelling-house that is, or has at any time in your period of ownership been, your only or main residence, under conditions that GOV.UK lists.
Take a home you lived in, then let. A fraction of the gain is relieved: the months of main residence, the last 9 always included, divided by the months of ownership.
The assumptions: one seller, sole owner, UK resident throughout; only the costs GOV.UK lists by name are counted.
With £30,000 of taxable income instead, the same seller would see £7,700 of the gain fall in what remains of the £37,700 basic rate band at 18% (£1,386) and the other £67,300 at 24% (£16,152): tax of £17,538. No Letting Relief applies, because the house was never shared with the tenant. The 3-year absence adds no months either, because the owner never returned to live there.
Completion on 1 July 2026 puts the return and the payment on or before 30 August 2026, the 60th day following it.
The relief follows the calendar, not the market: months lived in, plus nine, over months owned.
Your gain is added to your taxable income for the year, and that total decides the rate. Each individual has an annual exempt amount, £3,000 for 2026 to 2027, set against the gains charged at the highest rates.
According to GOV.UK (rates from 6 April 2026), individuals pay 18% or 24%. A higher or additional rate taxpayer pays 24%; a basic rate taxpayer pays 18% on the part of the gain that stays within the £37,700 basic rate band once added to taxable income, and 24% above it. The separate residential rate of 28% ended on 5 April 2024, and since 30 October 2024 property carries the same rates as other assets.
| Reduces the gain | Does not reduce the gain |
|---|---|
| Estate agents' and solicitors' fees on the purchase and on the sale | Normal maintenance, such as decorating |
| Improvement works, such as an extension | Interest on a loan to buy the property |
A second home that was once your main home still counts its months of main residence and the final 9, as in the example.

Begin Your Journey With UsSooner than for gains on other assets. For a UK resident selling UK residential property, Schedule 2 to the Finance Act 2019 requires the return to be delivered, and the tax paid on account, on or before the 60th day following completion.
| Date | What it fixes |
|---|---|
| Exchange of contracts (for a conditional contract, the date the conditions are satisfied) | The tax year, and with it the rates and the annual exempt amount |
| Completion | The start of the 60 days, and the end of the period of ownership used for the relief |
This point is easy to misread: the tax year is fixed before the 60 days begin.
If you are UK resident, no return is due where no tax is payable on account, for instance where your total gains are below the annual exempt amount. The rule is different for a non-resident.
The return is made through an online Capital Gains Tax on UK property account, and both dates are among the details required. If you are registered for Self Assessment, the sale also goes in your annual return. Because the rate depends on your taxable income for the year, the 60-day figure may have to be worked out before that income is known. Gains on other assets follow the Self Assessment calendar instead.
HMRC states that “You may have to pay interest and a penalty if you do not report and pay on time”. Its general late-filing scale for Income Tax and Capital Gains Tax returns (factsheet CC/FS18a, May 2022) starts with an initial penalty of £100, with further penalties after 6 and 12 months, and none where there is a reasonable excuse. The factsheet does not name the property return.
Leaving the United Kingdom does not take your UK property out of its tax: gains on UK property and land are taxed even if you are non-resident. Living in a country that taxes no personal income does not change it. According to the UAE Government portal (accessed October 2026), individuals owe no income tax in the UAE, and the UK charge remains.
HMRC's guidance for non-resident sellers (updated 6 April 2026) sets four rules.
| Rule | What it says | Date or figure |
|---|---|---|
| Reporting | Every disposal is reported, even with no tax to pay or at a loss | Within 60 days of completion |
| Scope | Residential, non-residential and mixed-use property and land; indirect disposals of rights deriving at least 75% of their value from UK land (25% interest or more) | Since 6 April 2019 |
| Rebasing | Residential property owned before 6 April 2015: the standard method taxes only the gain since that date, with improvement costs counted from it. Other methods: time apportionment of the whole gain, or the gain over the whole period | Market value at 5 April 2015; 5 April 2019 by default for non-residential property and indirect disposals |
| Rates and allowance | As for a resident: the gain is added to taxable UK income; the annual exempt amount is in most cases available | 18% or 24% for 2026 to 2027 |
The valuation is your responsibility, and none had to be obtained in April 2015 or April 2019. A loss is set against gains on UK property or land only. If the property was your residence, Private Residence Relief may apply to all or part of the gain, subject to the 90-day rule, and the home can be nominated on the return made after the disposal.
This rebasing is a rule for the non-resident seller of UK land, not a revaluation of assets on arriving in, or leaving, the UK. The Statutory Residence Test settles non-residence, and a seller who returns within 5 years may see certain gains charged in the year of return.
Many UK double taxation treaties can determine whether the UK may tax the disposal; where one exempts the gain, the UK return is still filed to claim relief, as the guide to capital gains and property under the UK-US treaty shows for one of them.
Leaving the United Kingdom does not take your UK property out of its tax: gains on UK property and land are taxed even if you are non-resident, and every disposal is reported.
If you are UK resident, you pay Capital Gains Tax when you dispose of an overseas property, and you may also have to pay tax in the country where the gain is made. As a rule, tax treaties let the State where immovable property is situated tax the gain on it, whereas most other gains are taxable only where the seller is resident. A home abroad can qualify for Private Residence Relief, subject to the 90-day rule.
Spain illustrates the principle: a gain on real estate there is taxed in Spain even when the seller is non-resident.
For land or a house, GOV.UK says tax is paid in both countries, with relief from the UK. The UK credit is the lower of the foreign tax paid, or allowed by the treaty, and the UK tax on the same gain. HMRC's real time service cannot be used to claim it for overseas property: see relief for tax paid abroad on a property sale.
Your relationship to the other party also changes who is taxed, and on what.
| Situation | Rule |
|---|---|
| Gift to someone other than a spouse or civil partner, or sale below value to help the buyer | Gain worked out on the market value: tax can be due with no cash received |
| Transfer to a spouse or civil partner you live with | No Capital Gains Tax on the transfer; the recipient takes over the original cost for a later sale |
| Jointly owned property | Each owner works out and reports the gain or loss on their own share, with their own annual exempt amount and rate |
| Seller abroad (for instance in the UAE) with UK property | The non-resident rules of the previous section apply |

Usually not, where it was your only or main residence throughout your ownership: the gain is fully relieved. Relief is restricted where part was let or used exclusively for business, where grounds exceed the permitted area, or where it was bought to realise a gain.
The statute asks whether the house was, at some time in your ownership, your only or main residence. The relief then follows the months of residence, plus the final 9 months, over the months of ownership. Contact us for more information.
It is an absence allowance within Private Residence Relief, not a tax-free holding period.
A property that is not your main home is within the charge, at 18% or 24% for 2026 to 2027 after the £3,000 annual exempt amount. Return and payment fall within 60 days of completion. Begin your journey with us.
Not on inheriting it: Capital Gains Tax arises only when you later dispose of the property. The market value is used where the Inheritance Tax value is not known. Inheritance Tax on the estate is a separate tax.
