Capital Gains Tax UK: Property, Shares, Reliefs and Annual Exemptions

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.

Tax information is based on HMRC rules for the 2026/27 tax year. Tax rules can change — always verify current rates at GOV.UK. This is not tax advice. Consider consulting a qualified tax adviser for your personal situation.

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.

Step-by-Step CGT Calculation

StepWhat to calculate
1Sale price (the amount you sell for)
2Minus base cost (what you paid, or probate value if inherited)
3Minus purchase costs (Stamp Duty, solicitor fees, survey on purchase)
4Minus selling costs (estate agent fees, solicitor fees, EPC)
5Minus qualifying improvements (extensions, new kitchen — not repairs)
6= Total gain
7Minus annual exempt amount (£3,000)
8Minus any reliefs (Private Residence Relief, lettings relief)
9= Taxable gain
10Apply CGT rate (18% or 24% depending on your total income)

Worked Example — Selling a Buy-to-Let

ItemAmount
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

ItemAmount
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)

DetailInformation
What it doesExempts periods where the property was your main home
How it worksGain is apportioned by time — months occupied vs total months owned
Final period exemptionLast 9 months of ownership are always exempt (even if not living there)
NominationYou 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

DetailCalculation
Owned for 10 years (120 months)
Lived in as main home for 3 years (36 months)
Final 9 months always exempt9 months
Total exempt months36 + 9 = 45 months
Total gain£100,000
Exempt portion45/120 × £100,000 = £37,500
Taxable portion£100,000 − £37,500 = £62,500

Lettings Relief

DetailInformation
What it doesReduces CGT where a property was both your home and let out
Current rulesOnly applies if you shared occupation with the tenant (e.g. lodger)
Maximum reliefLowest of: gain from letting period, £40,000, or the PRR amount
Practical impactVery limited since April 2020 — only benefits those with live-in lodgers

Transfer Between Spouses

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 band24%
Split across both bands18% on the part within basic rate, 24% on the rest

Split Rate Example

DetailAmount
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

Transfer to spouse before saleUse their CGT allowance too (£3,000 + £3,000 = £6,000)
Transfer to lower-earning spouseThey may pay 18% instead of 24%
Claim all allowable improvementsKeep receipts for extensions, renovations
