What Is the Capital Gains Tax Annual Exempt Amount?
The Capital Gains Tax Annual Exempt Amount is an annual tax-free amount that can be set against relevant capital gains. For most individuals, the Annual Exempt Amount is £3,000 for the 2026/27 tax year.
It applies to capital gains rather than to the amount of money received when an asset is sold. It also applies across your relevant gains for the tax year rather than providing a separate £3,000 exemption every time you sell an investment.
If your overall gains, after applying the relevant rules for losses and reliefs, are within your available Annual Exempt Amount, there may be no Capital Gains Tax to pay on those gains.
How the Annual Exempt Amount Works
The Annual Exempt Amount forms part of your overall Capital Gains Tax calculation rather than applying separately to each investment sale.
£3,000 for 2026/27
The Annual Exempt Amount for most individuals is £3,000 for the 2026/27 tax year.
Applies to gains
The exemption applies to relevant capital gains rather than to the total proceeds received when investments or other assets are sold.
Annual exemption
The amount applies to your Capital Gains Tax position for the tax year and cannot simply be recreated for each disposal.
Consider gains together
Relevant gains and allowable losses across the tax year need to be considered before establishing how much gain remains above the available exemption.
The Annual Exempt Amount therefore needs to be understood as one stage within the wider Capital Gains Tax calculation. A single investment sale does not normally determine how much of the exemption is ultimately available against your overall gains.
Is the £3,000 Exemption Per Investment You Sell?
No. The £3,000 Annual Exempt Amount is not a separate exemption for each investment, each sale or each taxable investment account.
Suppose you make a £2,000 gain when selling Investment A and another £2,000 gain when selling Investment B during the same tax year. Looking at either disposal on its own might suggest that the gain is below £3,000, but the two gains together amount to £4,000 before considering any allowable losses or reliefs.
This distinction becomes increasingly important where investments are bought and sold through several accounts or platforms. The fact that the transactions appear on separate statements does not give each account its own Capital Gains Tax exemption.
Does the Annual Exempt Amount Apply to the Sale Price or the Gain?
The Annual Exempt Amount applies to capital gains, not simply to the amount you receive when an investment is sold.
For example, suppose you bought an investment for £15,000 and later sold it for £19,000. Ignoring other allowable costs and adjustments, the starting gain would be £4,000. It is the gain that matters for the Annual Exempt Amount rather than the £19,000 of sale proceeds.
This means that selling investments worth considerably more than £3,000 does not automatically mean you have exceeded the Annual Exempt Amount. Equally, a relatively small disposal could still produce a substantial gain if the investment originally cost much less.
The calculation of a capital gain can involve acquisition costs, disposal costs and other rules, particularly where the same investment has been purchased at different times. Capital Gains Tax on Investments Explained covers those calculations in more detail.
How Are Several Capital Gains Combined?
When several relevant disposals occur during the same tax year, their gains need to be considered as part of the overall Capital Gains Tax position rather than treating each disposal as having its own Annual Exempt Amount.
Consider a simplified example in which three investments are sold at gains during the same tax year.
This simplified example shows how gains from several disposals can build towards the same Annual Exempt Amount. This is a simplified illustration and does not calculate the Capital Gains Tax rate that may apply.Combining Several Capital Gains
The example demonstrates why the exemption cannot be assessed by looking only at whether each individual gain exceeds £3,000.
It also shows why keeping records of disposals across the whole tax year can matter. Several relatively modest gains can produce a different overall position when they are brought together.
How Do Capital Losses Affect the Annual Exempt Amount?
Allowable capital losses can reduce gains before the Annual Exempt Amount is applied. This means the order in which gains, losses and the exemption are considered can affect how much gain ultimately remains chargeable.
Suppose you have £8,000 of gains during the tax year and £2,000 of allowable losses arising in that same year. Deducting those losses leaves £6,000 of net gains. Applying a £3,000 Annual Exempt Amount would then leave £3,000 of gains above the exemption.
Losses brought forward from earlier tax years can work differently. Where the relevant conditions are met, brought-forward losses generally only need to be used to reduce gains to the level of the available Annual Exempt Amount. This can allow remaining qualifying losses to continue to be carried forward for potential use in later years.
Capital losses therefore should not simply be treated as interchangeable with the Annual Exempt Amount. Both can reduce the amount of gain ultimately exposed to Capital Gains Tax, but they operate under different rules.
Can You Choose Which Gains Use the Annual Exempt Amount?
Where different gains would otherwise be charged at different Capital Gains Tax rates, the Annual Exempt Amount can be used against gains in the way that produces the most beneficial tax result.
This can matter because not every capital gain is necessarily taxed at the same rate. The type of gain and the individual’s wider tax position can affect the rate that would otherwise apply.
For example, if part of someone’s gains would otherwise be charged at a higher CGT rate than another part, using the exemption against the higher-rate gains can reduce the tax bill more than using it against lower-rate gains.
This does not increase the amount of the Annual Exempt Amount. It changes which gains the available exemption is set against.
The detailed CGT rate calculation is covered in Capital Gains Tax on Investments Explained.
Can You Carry Forward Unused Annual Exempt Amount?
No. The Annual Exempt Amount relates to a particular tax year. Any part that is not used does not accumulate for use in later years.
Suppose your relevant gains for 2026/27 amount to £1,000 and you have the full £3,000 Annual Exempt Amount available. The remaining £2,000 does not carry forward and increase the exemption available in the following tax year.
The position is considered again using the Annual Exempt Amount applying to that later tax year.
Unused Annual Exempt Amount
Any unused Annual Exempt Amount does not carry forward to a future tax year. It applies only to the tax year for which it is available.
Unused Allowable Capital Losses
Qualifying allowable losses that cannot be used may potentially be carried forward under the Capital Gains Tax rules and used against gains in later tax years.
The Annual Exempt Amount expires if unused, while qualifying unused capital losses can potentially continue into future tax years.
This difference can be important when reading a Capital Gains Tax calculation. An unused exemption from an earlier year cannot be brought into the current calculation in the same way that qualifying carried-forward losses potentially can.
Does Everyone Get a £3,000 Annual Exempt Amount?
For the 2026/27 tax year, £3,000 is the standard Annual Exempt Amount for most individuals. The amount is not increased simply because someone pays Income Tax at a higher rate.
Different amounts can apply in other circumstances. For example, the Annual Exempt Amount for most trustees is £1,500 for 2026/27, while trustees for disabled people can qualify for the £3,000 amount.
There are also specialist circumstances in which an individual may not qualify for an Annual Exempt Amount, including certain claims connected with the foreign income and gains regime or Overseas Workday Relief.
For most individual investors using a General Investment Account, however, the standard £3,000 individual Annual Exempt Amount is the relevant starting point for 2026/27.
Does the Annual Exempt Amount Apply to Investments in an ISA?
Gains arising from eligible investments held within an ISA are not subject to UK Capital Gains Tax. They therefore do not need to use the Annual Exempt Amount to receive that tax treatment.
Suppose an investor realises a £2,000 gain from investments held in a General Investment Account and a £5,000 gain from investments held within a Stocks & Shares ISA.
The £5,000 gain within the ISA does not use £5,000 of the investor’s Annual Exempt Amount. The ISA gain is outside the normal CGT charge because of the ISA tax wrapper.
The £2,000 gain outside the ISA would instead form part of the investor’s relevant Capital Gains Tax position, alongside any other chargeable gains and allowable losses.
ISA Tax Benefits Explained looks more broadly at how the ISA wrapper affects capital gains, dividends and interest.
What If Your Gains Are Exactly £3,000?
If an individual has the full £3,000 Annual Exempt Amount available and their overall relevant gains after applying the appropriate losses and reliefs are £3,000, those gains would be covered by the exemption.
This does not mean that every £3,000 gain can automatically be ignored. Other relevant disposals during the tax year still need to be considered because the exemption applies to the overall position rather than separately to each gain.
It is also useful to distinguish between having Capital Gains Tax to pay and having a reporting obligation. Whether a disposal or gain needs to be reported can depend on separate HMRC rules and the individual’s circumstances.
Do You Pay Tax When You Sell Investments? explains the distinction between making a disposal, making a gain and ultimately having Capital Gains Tax to pay.
Does the Annual Exempt Amount Reduce Your Income Tax?
No. The Annual Exempt Amount belongs to the Capital Gains Tax system. It cannot simply be transferred to other forms of taxable income because it has not been used against capital gains.
For example, unused Annual Exempt Amount cannot be used against salary, pension income, savings interest or dividends.
Those forms of income are dealt with under the relevant Income Tax rules and may have their own allowances or tax treatments. The Dividend Allowance, for example, performs a different job from the Capital Gains Tax Annual Exempt Amount.
This separation is important because someone can have several different allowances available during the same tax year, but they are not necessarily interchangeable.
How the Annual Exempt Amount Fits Into a CGT Calculation
The Annual Exempt Amount is applied as part of the wider Capital Gains Tax calculation rather than separately to every investment sale.
-
Identify the relevant gains
Establish which disposals produced chargeable gains during the tax year and calculate those gains under the applicable Capital Gains Tax rules.
-
Bring the gains together
Consider the relevant gains across the tax year rather than giving each disposal its own Annual Exempt Amount.
-
Apply allowable losses and reliefs
Deduct allowable losses and apply any relevant reliefs according to the Capital Gains Tax rules.
-
Apply the Annual Exempt Amount
Use the available Annual Exempt Amount against the remaining gains. For most individuals this is £3,000 for 2026/27.
-
Consider any remaining chargeable gains
If gains remain above the available exemption, those gains move into the Capital Gains Tax rate calculation.
The Annual Exempt Amount is one annual exemption against your relevant capital gains. It is not a separate £3,000 allowance for every investment, account or disposal.
Conclusion
The Capital Gains Tax Annual Exempt Amount provides most individuals with a £3,000 exemption against relevant capital gains for the 2026/27 tax year.
The most important point is that this is an annual exemption against your overall Capital Gains Tax position. It is not £3,000 for every investment you sell, every disposal you make or every investment account you hold.
Relevant gains need to be considered together, with allowable losses and reliefs applied under the appropriate rules before the available Annual Exempt Amount is taken into account. Any gain remaining above the exemption can then move into the Capital Gains Tax rate calculation.
Unused Annual Exempt Amount does not carry forward to a later tax year, while qualifying unused capital losses potentially can. Keeping those two concepts separate makes it much easier to understand the role the Annual Exempt Amount plays within the wider Capital Gains Tax calculation.
