Capital Gains Tax allowance and rates for 2026/27

Knowing your capital gains tax allowance is the first step to working out what you owe. This guide sets out the annual exempt amount and rates for the 2026/27 tax year.

What is the Capital Gains Tax allowance for 2026/27?

The annual exempt amount is £3,000 for 2026/27. It is the total of chargeable gains you can make in the tax year before any Capital Gains Tax is due, and it is shared across everything: shares, funds and crypto together, not per asset.

The allowance cannot be carried forward. If you do not use it in a tax year, it is gone.

The current CGT rates

For disposals of shares and cryptoassets on or after 30 October 2024, the rates are:

• 18% on gains that fall within your remaining basic-rate income band.
• 24% on gains above that band.

These rates apply to the taxable gain, which is your total gains minus losses minus the £3,000 allowance.

How the allowance is applied

You add up your gains, subtract any allowable losses (including losses carried forward from earlier years), then subtract the £3,000 allowance. What remains is taxed at the rates above. Pooled applies the allowance for you and shows how much of it you have used.

Plan around the allowance

Because the allowance resets each 6 April and cannot be carried forward, it can be worth knowing where you stand before the tax year ends. Pooled shows your remaining allowance and lets you model a hypothetical disposal, purely as information, never as advice to buy or sell.
