CGT on property (2026/27)

You pay Capital Gains Tax when you sell a residential property that isn't your main home — a second home, buy-to-let or inherited property. The first £3,000 of gains is tax-free; the rest is taxed at 18% (within your basic-rate band) or 24% (above it).

🏠 Your main home is normally exempt under Private Residence Relief. If a property was your main home for part of the time you owned it, part of the gain may be relieved.

How the rate is decided

Your taxable gain is added on top of your income. The part within your remaining basic-rate band is taxed at 18%; anything above is 24%. Since 30 October 2024, property uses the same 18%/24% rates as other assets.

⏱️ You must report and pay CGT on UK residential property within 60 days of completion.

Example: £40,000 income + £60,000 gain

After the £3,000 allowance, £57,000 is taxable. With £40,000 income, about £10,270 of basic-rate band remains (taxed at 18% = £1,849), and the remaining £46,730 at 24% (£11,215) — a total of roughly £13,064.

Is my main home taxed?

Usually not — Private Residence Relief normally makes your main home exempt. CGT typically applies to additional properties.

Can I deduct costs?

Yes — buying/selling costs and qualifying improvements reduce the gain. Enter your net gain (after costs) above.
