On a £10,000 capital gain with a £30,000 salary, your CGT is £700 on shares and other assets (10% basic rate), or £1,260 on residential property (18% basic rate). After the £3,000 annual exempt amount, your taxable gain is £7,000.

How UK Capital Gains Tax works

Capital Gains Tax is charged on the profit when you sell (or "dispose of") an asset that has increased in value. In the 2026-27 tax year, everyone gets a £3,000 annual exempt amount — gains below this are tax-free (reduced from £6,000 in 2023/24 and £12,300 in 2022/23).

CGT rates depend on the type of asset:

• Shares, crypto & other assets: 10% (basic rate) / 20% (higher rate)
• Residential property: 18% (basic rate) / 24% (higher rate)

Which rate you pay depends on your total taxable income — your gain sits on top of your other income when determining which band applies. If your salary already uses up the basic rate band (£37,700 of taxable income), your entire gain is taxed at the higher rate.

Your CGT band breakdown

With a £30,000 salary, your taxable income (after the £12,570 personal allowance) is £17,430. This uses £17,430 of the £37,700 basic rate band, leaving £20,270 of basic rate band available for your gain.

Of your £7,000 taxable gain (after the £3,000 exempt amount):

• £7,000 falls in the basic rate band

Residential property vs other assets

With a £30,000 salary, you pay £700 CGT on shares/crypto or £1,260 on residential property. The £3,000 annual exempt amount is deducted first.

When do you pay Capital Gains Tax?

For most assets, you report and pay CGT through your Self Assessment tax return by 31 January following the end of the tax year. For UK residential property, you must report and pay within 60 days of completion using the "Report and pay CGT on UK property" service.

What is Private Residence Relief?

Your main home (private residence) is usually exempt from CGT when you sell it, provided you have lived in it as your only or main home for the entire period of ownership. This is known as Private Residence Relief (PRR). Letting relief may also apply if you rented out part of your home.

Yes. Capital losses from the same tax year are automatically offset against gains. Losses from previous years can be carried forward and used to reduce gains below the annual exempt amount. You must report losses to HMRC within 4 years to carry them forward.
