What is Capital Gains Tax?
Capital Gains Tax (CGT) can be due when you sell something that’s increased in value, or you transfer it outside of your estate, e.g. to another person or into a trust. It can apply when selling or transferring lots of different assets, for example shares or property.

Moving investments into an ISA or pension this tax year shelters investments from tax in future years. Investments held within these accounts can grow free from Capital Gains Tax. With a pension you could also get tax relief on your contributions, subject to annual limits. Please note that you may generate a taxable gain in the tax year investments are moved.

You’ll usually need to be at least 55 (rising to 57 from 2028) before you can access the money in your pension. Pension and tax rules can change and any benefits will depend on your circumstances.

How is Capital Gains Tax calculated?
Each tax year you can make a set amount in capital gains before paying any tax – this is known as the ‘annual exempt amount’, or more simply your ‘CGT allowance’. Last tax year the CGT allowance was £12,300 but it has been cut to £6,000 this tax year. From April 2024 it is being cut further to £3,000 and could change again in the future.
You only pay tax on any gain over your allowance each tax year. For example, if you made a £15,000 gain in the current tax year, you’ll pay tax on a gain of £9,000.
The amount you pay in CGT depends on what you’re selling and the income tax band you fall into.
Capital Gains Tax calculations
Income tax band | Investments | Property |
---|---|---|
Basic rate | 10% | 18% |
Higher rate | 20% | 28% |
Additional rate | 20% | 28% |
Scottish taxpayers should use the ‘rest of UK’ tax bands to determine the rate at which they will pay CGT.
If you don’t use your allowance in a tax year, you can’t roll it over to the next tax year.
How can I reduce my Capital Gains Tax bill?
If you make any losses you can use them to reduce any gains made in the same tax year. If you make more losses in a year than gains you should report them, as they can be carried forward to reduce gains in future years. If you have forgotten to report losses, you can claim them up to 4 years after the end of the tax year in which the losses were incurred.
You can transfer investments to a spouse or civil partner free of Capital Gains Tax.
If you’re investing in shares or funds, you can shelter any gains from CGT by investing through an ISA, such as the HL Stocks and Shares ISA, or a pension, such as the HL Self-Invested Personal Pension (SIPP). Any gains within these accounts do not incur CGT.
However please bear in mind that a pension is meant for your retirement, so you can’t normally access your money until you’re 55 (57 from 2028).
