A clear statutory rule dictates exactly who pays Capital Gains Tax in the UK: individuals, personal representatives of a deceased estate, and trustees who realise a profit from disposing of a chargeable asset. With the annual tax-free allowance fixed at a historically low £3,000, thousands of modest investors, second homeowners, and retirees now fall within its scope.
This guide breaks down exactly who pays Capital Gains Tax, who is exempt, and what happens in less obvious situations such as joint ownership, non-residency, and trusts.
Who Pays Capital Gains Tax in the UK?
Capital Gains Tax applies to four main categories of taxpayer:
- UK resident individuals: Anyone resident in the UK who disposes of a chargeable asset at a profit, whether they are employed, self-employed, or not working at all.
- Non-UK residents: Non-residents pay Capital Gains Tax on disposals of UK land and property, and in some cases on UK business assets, even though they are not otherwise UK taxpayers.
- Trustees: Trusts that dispose of chargeable assets held within the trust pay Capital Gains Tax, usually at a flat rate rather than the individual bands.
- Personal representatives: Executors and administrators who sell assets belonging to a deceased person’s estate during the administration period are liable for any gain arising after the date of death.
Limited companies do not pay Capital Gains Tax. Instead, gains made by a company are charged to Corporation Tax as part of its overall taxable profits.
When Do You Actually Have to Pay?
Not everyone who disposes of an asset ends up with a tax bill. You only pay Capital Gains Tax once your total gains in a tax year exceed the Annual Exempt Amount. For 2026/27, this threshold is:
- £3,000 for individuals and most personal representatives.
- £1,500 for the majority of trustees.
If your total gains stay below this threshold, no Capital Gains Tax is due, although you may still need to report the disposal if the proceeds (not just the gain) exceed certain limits, particularly for UK residential property.
Who Does Not Have to Pay Capital Gains Tax?
Several groups and situations fall outside the charge entirely:
- Anyone selling their main home: Private Residence Relief generally removes the gain in full if the property has been your only or main residence throughout ownership.
- Spouses and civil partners transferring assets between themselves: These transfers happen on a no gain, no loss basis, so no Capital Gains Tax arises at the point of transfer.
- People gifting to UK charities: Gifts of qualifying assets to registered charities are exempt.
- ISA and pension holders: Gains made within an ISA or a registered pension scheme are entirely free of Capital Gains Tax.
- Anyone whose total gains fall within the £3,000 Annual Exempt Amount: No tax is due if your total gains for the year do not exceed this threshold.
Joint Ownership: Who Pays When an Asset Has More Than One Owner?
When an asset is owned jointly, such as by a married couple, business partners, or friends who bought a property together, each owner is individually liable for Capital Gains Tax on their own share of the gain. Each co-owner has their own £3,000 Annual Exempt Amount, meaning a couple who jointly own a buy-to-let property can shelter up to £6,000 of combined gains before any tax is due.
Non-Residents and UK Property
Since 2015, non-UK residents have been brought into the scope of Capital Gains Tax on UK residential property, and since 2019 this has extended to commercial property and land. Non-residents disposing of UK property must report the disposal within 60 days of completion, in the same way UK residents must for residential property, regardless of whether any tax is actually due.
Trustees and Personal Representatives: The Details
Trustees of most settlements pay Capital Gains Tax at a flat 24% rate on chargeable gains, rather than the 18%/24% bands that apply to individuals. Personal representatives administering an estate benefit from the same £3,000 Annual Exempt Amount as an individual, but only for the tax year of death and the following two tax years, after which any further gains within the estate lose access to the allowance.
Worked Example: Who Pays What on a Jointly Owned Property
Consider a married couple who jointly own a buy-to-let flat and sell it for a combined gain of £40,000. Because they are treated as individual taxpayers for Capital Gains Tax purposes, the gain is split according to their ownership share, typically 50/50 unless recorded otherwise. Each spouse then applies their own £3,000 Annual Exempt Amount, leaving £17,000 taxable per person rather than £34,000 for one person alone. This is one of the clearest illustrations of why understanding who pays Capital Gains Tax, and how ownership is structured, can make a significant difference to the total household tax bill.
Reporting Deadlines: Who Pays and When
Once you have established that you are liable, the reporting deadline depends on the type of asset:
- UK residential property: Report and pay within 60 days of completion, using the Capital Gains Tax on UK property service.
- Shares, business assets, and other chargeable assets: Report through your Self Assessment tax return, with any tax due by 31 January following the end of the tax year.
- Trustees and personal representatives: Report via the trust or estate’s own Self Assessment return, following the same 31 January deadline for non-property assets.
Missing these deadlines can trigger automatic penalties and interest, regardless of whether the amount of tax owed is large or small, so it is worth confirming who is responsible for reporting before the deadline passes.
What About Capital Gains Tax and Divorce or Separation?
Couples going through divorce or separation are a special case worth understanding, because who pays Capital Gains Tax can change significantly once a couple stops living together. Transfers between spouses only qualify for the no gain, no loss treatment up until the end of the third tax year after separation, or on the date of the final divorce settlement if that comes first, whichever is earlier under current rules.
After that window closes, any transfer of an asset between former spouses is treated as a normal disposal, meaning Capital Gains Tax can apply in the same way as a transfer to any other person. Couples who are separating and hold jointly owned property or investments should take advice early, since the timing of a transfer can materially change who pays Capital Gains Tax and how much is due.
Do Beneficiaries Pay Capital Gains Tax on Inherited Assets?
Beneficiaries do not pay Capital Gains Tax simply for inheriting an asset. Instead, the estate’s personal representatives are responsible for any Capital Gains Tax due if assets are sold during the administration period, using the value at the date of death as the new base cost.
Once an asset has been transferred out of the estate and into a beneficiary’s own name, that beneficiary then becomes the person who pays Capital Gains Tax on any future increase in value if they later sell it themselves.

Frequently Asked Questions About Who Pays Capital Gains Tax
What is the threshold for Capital Gains Tax in the UK?
For 2026/27, the threshold, known as the Annual Exempt Amount, is £3,000 for individuals and most personal representatives, and £1,500 for most trustees. You only pay Capital Gains Tax on gains above this amount.
How to avoid Capital Gains Tax on property in the UK?
You cannot legally avoid Capital Gains Tax on a genuine chargeable gain, but legitimate strategies include using Private Residence Relief on your main home, transferring a share to a spouse before sale to use both Annual Exempt Amounts, and timing disposals across different tax years.
Who does not have to pay Capital Gains Tax?
People selling their main home under Private Residence Relief, spouses transferring assets between themselves, those gifting to UK charities, ISA and pension holders, and anyone whose total annual gains fall within the £3,000 Annual Exempt Amount do not have to pay Capital Gains Tax.
How do I know if I need to pay Capital Gains Tax in the UK?
You need to check three things: whether the asset you disposed of is chargeable, whether your total gains for the tax year exceed the £3,000 Annual Exempt Amount, and whether a specific exemption or relief applies, such as Private Residence Relief for a main home.
