Capital Gains Tax on a £75,000 Gain 2026/27
After the £3,000 annual exempt amount, a basic-rate taxpayer (£35,000 other income) owes £16,364 CGT on a £75,000 gain. A higher-rate taxpayer (£55,000 other income) owes £17,280.
£75,000 is a typical gain on a buy-to-let or second home held for a decade or more, so this page leans towards property. £72,000 is taxable, and most of it is at 24% whatever your income: £16,363.80 for a seller on £35,000 and £17,280 on £55,000, effective rates of 21.8% and 23.0%.
Which rate does a £75,000 gain pay at different incomes?
| Other income | Band left | At 18% | At 24% | CGT |
|---|---|---|---|---|
| £20,000 | £30,270 | £30,270 | £41,730 | £15,463.80 |
| £35,000 | £15,270 | £15,270 | £56,730 | £16,363.80 |
| £45,000 | £5,270 | £5,270 | £66,730 | £16,963.80 |
| £55,000 | £0 | £0 | £72,000 | £17,280 |
Only the first slice of the gain can ever be at 18%: at most £37,700 of it, and only for someone with no taxable income. That is why a seller on £20,000 (£15,463.80) pays not far short of the bill at £55,000. Residential property is taxed at the same 18% and 24% as other assets in 2026/27.1
Every extra £1,000 of gain costs £240 at every income in the table, because the 18% slice has already been used. The reverse also holds: each £1,000 of allowable cost you can prove, such as an extension or the solicitor's bill when you bought, takes £240 off the bill.7

Spreading the sale over two tax years
A single property cannot be sold in two tax years, so the split-year row really applies to a share portfolio of this size, where it saves £1,636.20 or £720. For property, the equivalent lever is ownership: a property held jointly is taxed as two half gains.
Giving half to a spouse or civil partner
If the property is in one name, giving a share to your spouse before contracts are exchanged means two allowances and two bands. The engine puts the saving at £2,790 for a spouse with no income and £1,636.20 for one on £35,000.2 It must be a genuine gift of the share, not a transfer in name only.
Pensions, ISAs and reliefs
If you ever lived in the property as your main home, Private Residence Relief can cover part of the gain, always including the last 9 months you owned it. Letting Relief now only applies if you lived there at the same time as your tenants.6 A £20,000 gross pension contribution saves a higher-rate seller £916.20.3
Reporting and paying the tax
For UK residential property you must report and pay within 60 days of completion.4 The payment uses an estimate of your income for the year, and your tax return then settles the final figure. Proceeds will be well over £50,000, so the capital gains pages are needed as well.5

CGT on other gain amounts
Frequently asked questions
How much CGT on a £75,000 property gain?
£16,363.80 for a basic-rate earner on £35,000 and £17,280 for a higher-rate earner on £55,000, before any Private Residence Relief.
Can I deduct the costs of selling the property?
Yes. Estate agent and solicitor fees, stamp duty and legal costs from the purchase, and the cost of improvements (not repairs) are allowable costs that reduce the gain.
Is the 60-day payment my final bill?
No. It is a payment on account. Your Self Assessment return works out the year's CGT on all your gains with your actual income, and any difference is paid or repaid.
