Capital Gains Tax on Selling a Second Home or Property UK
How much Capital Gains Tax you pay when selling a second home, buy-to-let, or inherited property — with worked examples, reliefs, and the 60-day reporting rule.
When you sell a property that isn’t your main home, you usually pay Capital Gains Tax on the profit. Here’s how to calculate it and how to reduce it.

Worked Example — Selling a Buy-to-Let
| Item |
Amount |
| Sale price |
£350,000 |
| Purchase price (2015) |
£220,000 |
| Stamp Duty paid on purchase |
£8,500 |
| Solicitor fees on purchase |
£1,200 |
| Solicitor fees on sale |
£1,500 |
| Estate agent fee on sale (1.5%) |
£5,250 |
| Extension added (2018) |
£25,000 |
| New bathroom (2020) |
£5,000 |
| Total gain |
£350,000 − £220,000 − £8,500 − £1,200 − £1,500 − £5,250 − £25,000 − £5,000 = £83,550 |
| Annual exempt amount |
−£3,000 |
| Taxable gain |
£80,550 |
| CGT at 24% (higher rate) |
£19,332 |
Worked Example — Selling an Inherited Property
| Item |
Amount |
| Probate value (value at date of death) |
£280,000 |
| Sale price (sold 18 months later) |
£310,000 |
| Solicitor fees (purchase equivalent = probate costs) |
£3,000 |
| Solicitor and agent fees on sale |
£7,000 |
| Total gain |
£310,000 − £280,000 − £3,000 − £7,000 = £20,000 |
| Annual exempt amount |
−£3,000 |
| Taxable gain |
£17,000 |
| CGT at 24% |
£4,080 |
Key point: You don’t pay CGT on the increase from when the deceased originally bought it — only from the probate value.

Reliefs That Can Reduce CGT
Private Residence Relief (PRR)
| Detail |
Information |
| What it does |
Exempts periods where the property was your main home |
| How it works |
Gain is apportioned by time — months occupied vs total months owned |
| Final period exemption |
Last 9 months of ownership are always exempt (even if not living there) |
| Nomination |
You can nominate which property is your main residence (if you own more than one) within 2 years of acquiring the second property |
PRR Worked Example
| Detail |
Calculation |
| Owned for 10 years (120 months) |
|
| Lived in as main home for 3 years (36 months) |
|
| Final 9 months always exempt |
9 months |
| Total exempt months |
36 + 9 = 45 months |
| Total gain |
£100,000 |
| Exempt portion |
45/120 × £100,000 = £37,500 |
| Taxable portion |
£100,000 − £37,500 = £62,500 |
Lettings Relief
| Detail |
Information |
| What it does |
Reduces CGT where a property was both your home and let out |
| Current rules |
Only applies if you shared occupation with the tenant (e.g. lodger) |
| Maximum relief |
Lowest of: gain from letting period, £40,000, or the PRR amount |
| Practical impact |
Very limited since April 2020 — only benefits those with live-in lodgers |
Transfer Between Spouses
| Detail |
Information |
| Transfers between spouses/civil partners |
No CGT — transfer at “no gain, no loss” |
| Separating couples |
Must transfer within 3 years of separation for no-gain treatment |
| Strategy |
Transfer to the spouse with the lower tax rate before selling |
The 60-Day Reporting Rule
| Detail |
Information |
| What to report |
Any UK residential property disposal where CGT is due |
| Deadline |
60 days from completion (not exchange) |
| How to report |
HMRC’s online service: “Report and pay Capital Gains Tax on UK property” |
| Payment |
Due at the same time — within 60 days |
| Late filing penalty |
£100 |
| Still need Self Assessment? |
Yes — include the gain on your tax return for the year (credit the 60-day payment) |
| No gain/loss-making sale |
No need to report within 60 days (but still declare on tax return) |
How Your Tax Band Affects CGT
Your CGT rate depends on your total income plus the gain:
| Total taxable income (salary + rental + gain) |
CGT rate on property |
| Within basic rate band (under £50,270) |
18% |
| Above basic rate band |
24% |
| Split across both bands |
18% on the part within basic rate, 24% on the rest |
Split Rate Example
| Detail |
Amount |
| Salary |
£40,000 |
| Taxable income (after Personal Allowance) |
£27,430 |
| Basic rate band remaining |
£50,270 − £27,430 = £22,840 |
| Taxable property gain |
£50,000 |
| Gain taxed at 18% |
£22,840 × 18% = £4,111 |
| Gain taxed at 24% |
£27,160 × 24% = £6,518 |
| Total CGT |
£10,629 |
Ways to Reduce Your CGT Bill
| Strategy |
How it helps |
| Use your annual exempt amount (£3,000) |
Deduct automatically |
| Transfer to spouse before sale |
Use their CGT allowance too (£3,000 + £3,000 = £6,000) |
| Transfer to lower-earning spouse |
They may pay 18% instead of 24% |
| Claim all allowable improvements |
Keep receipts for extensions, renovations |
| Claim all purchase and sale costs |
Stamp duty, solicitor fees, agent fees |
| Pension contributions |
Reduce your taxable income, keeping more gain in the basic rate band |
| Timing the sale |
Sell in a year when your other income is lower |
| Private Residence Relief |
If you genuinely lived in the property for any period |
