Capital Gains Tax on Property Sales 2026

Capital Gains Tax on Property Sales 2026

Overview of Capital Gains Tax on Property for 2025-26

 

What is Capital Gains Tax on Property?

Capital Gains Tax (CGT) is a tax on the profit (gain) made when selling or disposing of an asset that has increased in value. For UK residential property, CGT applies when selling second homes, buy-to-let properties, or any property other than your main residence.

  • Main homes are generally exempt due to Private Residence Relief.
  • Gains from buy-to-let or second homes are taxable if they exceed the annual CGT allowance.

Annual Allowance for 2025-26

  • The annual CGT allowance for individuals in the tax year 2025-26 is £3,000.
  • For couples jointly owning property, the allowance doubles to £6,000.
  • This allowance is the amount of gain you can realise tax-free.
  • Unused allowance cannot be carried forward to subsequent years.​

 

CGT Rates for Property Sales

CGT rates for residential property sales depend on your taxable income:

Income Tax Band

CGT Rate on Residential Property Gains

Basic Rate

18%

Higher/Additional Rate

24%

The CGT rate is applied on the gain after using the annual allowance and allowed deductions. Importantly, the capital gain is added on top of your other taxable income to determine the rate band applicable.​

Calculating Capital Gains Tax on Property Sales

Step-by-Step Calculation

  1. Determine the Gain on Sale
    Gain = Sale Price – Purchase Price – Allowable Costs
    Allowable costs include:
  • Purchase price (including solicitor fees)
  • Costs of improvement (not repairs)
  • Selling costs (estate agent fees, solicitor fees).​
  1. Apply Annual Allowance
    Deduct the £3,000 allowance (or £6,000 for couples).
  2. Determine taxable gain
    Any amount above the allowance is taxable.
  3. Add Gain to Income to Determine Tax Band
    Combined taxable income + gain determines if gain is taxed at 18% or 24%.
  4. Calculate CGT Owed

 

Practical Calculation Example:

  • Property bought for £200,000 (with £5,000 in allowable improvements).
  • Sold for £350,000.
  • Selling costs: £10,000.
  • Other taxable income for the year: £45,000 (basic rate band).

 

Step 1: Gain = £350,000 – (£200,000 + £5,000 + £10,000) = £135,000
Step 2: Deduct allowance: £135,000 – £3,000 = £132,000 taxable gain
Step 3: Basic rate band limit is £50,270 for 2025/26 (assuming personal allowance has been used).
Combined income + gain = £45,000 + £132,000 = £177,000.
£50,270 – £45,000 = £5,270 taxed at 18%.
Remaining gain: £132,000 – £5,270 = £126,730 taxed at 24%.

CGT = (5,270 × 18%) + (126,730 × 24%) = £948.60 + £30,415.20 = £31,363.80 tax owed.​

60-Day Reporting Rule

  • Taxpayers must report and pay CGT for UK residential property within 60 days from the completion date of the sale.
  • Failure to comply leads to penalties and interest.
  • Reporting is done via the UK property Capital Gains Tax return on HMRC’s online portal.​

 

Filing a Self-Assessment Tax Return

  • Even if the 60-day return is filed, a self-assessment tax return may still be required depending on your tax circumstances.
  • Reporting obligations also apply to non-residents disposing UK property.​

Private Residence Relief (PRR)

  • Exempts your main home from CGT.
  • Partial relief may apply if part of the property was rented out.
  • Last 9 months of ownership counted as if the property was your main residence to extend relief.​

 

Spousal Transfers

  • Transfers between spouses and civil partners are exempt from CGT.
  • Allows usage of both allowances by transferring property ownership share.​

 

Other Reliefs

  • Letting Relief, mainly abolished but may apply in limited cases.
  • Relief in case of gifting property to charity (exempt).
  • Relief if property was occupied by a dependent relative (consult an adviser).​

 

Multiple Income Sources and Tax Bands

  • CGT must be calculated considering all sources of income.
  • Gains may push taxpayers into higher income tax bands, increasing CGT rate.
  • Important for self-employed or gig economy workers who may have fluctuating income.

 

Scottish and Welsh Variations

  • Scotland and Wales have different income tax rates but CGT for property follows UK-wide rules (18%/24%).
  • However, Income Tax band thresholds differ, affecting the CGT rate applied.

 

High-Income Child Benefit Charge Interaction

  • For high earners subject to the High Income Child Benefit Charge, additional tax liability may arise.
  • CGT gains can push taxpayers into the charge threshold.

 

Before Selling Property

  • Confirm property qualifies as your main residence for PRR.
  • Gather all cost receipts for purchase and improvements.
  • Check if you can transfer ownership to spouse before sale.
  • Calculate anticipated gain considering 2025/26 allowance.

 

When Reporting

  • Submit property disposal report within 60 days on HMRC portal.
  • Retain all documentation for calculations and relief claims.
  • File self-assessment return if required.

 

Ways to Reduce CGT

  • Time sale in a lower-income year.
  • Use both spouses’ CGT allowances.
  • Deduct allowable costs and improvements accurately.
  • Consider gifting to spouse or charity where appropriate.

CGT rates on residential property

Basic-rate taxpayers
18%
Applies to the portion of your gain that, when added to your taxable income, stays within the basic-rate band (up to £50,270).
Higher / additional-rate taxpayers
24%
Applies to any portion of your gain that pushes you above the basic-rate band, plus the gains of all higher-rate taxpayers.
i
Important context. Since the Autumn Budget 2024, residential-property CGT rates (18% / 24%) now also apply to most other chargeable assets such as shares. The annual allowance has fallen from £12,300 in 2022/23 to just £3,000 today — meaning many more property owners face a CGT bill on disposals.

When does CGT apply?

Type of property CGT typically due?
Your only or main home (continuously)No — Private Residence Relief
Buy-to-let / rental propertyYes
Second home or holiday homeYes
Inherited property (when you sell)Yes — gain measured from probate value
Property gifted to spouse / civil partnerNo (no gain / no loss)
Property gifted to anyone elseYes — at market value

How the gain is calculated

=
Gain = Sale price − Purchase price − Allowable costs. You pay CGT on the gain that sits above your annual allowance, not the sale price itself.

What you can deduct

Stamp Duty Land Tax (SDLT), solicitor fees, survey costs, and the price you originally paid all form the base cost.
Extensions, loft conversions, new kitchen, central heating installation — anything that adds value to the property and is still in place when you sell. Keep receipts and invoices.
Routine decorating, replacing a broken boiler with a like-for-like, fixing a leak. These are revenue costs, not capital. Mortgage interest is also not deductible against CGT.
Estate agent fees, solicitor / conveyancing fees, EPC, advertising costs.

Key reliefs

Fully exempts your only or main home from CGT for the years it was your main residence. The final 9 months of ownership always count as residence even if you've moved out. Partial relief applies if you let part of the property out or used it for business.
Transfers between spouses or civil partners trigger no CGT. Used strategically before sale, this lets a couple use both £3,000 allowances and potentially have part of the gain taxed at the lower 18% rate. Separating couples now have up to 3 years after the year of separation.
Since April 2020, Lettings Relief only applies where the owner shared occupation of the property with the tenant. If you moved out and let the whole place, this relief no longer applies.
No CGT at inheritance. Your base cost becomes the property's probate value. CGT applies only to the gain from that value to the eventual sale price — accurate probate valuations matter.
Property gifted directly to a registered charity is exempt from CGT.

Reporting & payment

!
The 60-day rule. UK residents must report and pay CGT on residential-property gains within 60 days of the completion date — via HMRC's online "Report and pay Capital Gains Tax on UK property" service. Late returns trigger an automatic £100 penalty plus daily and percentage-based penalties for further delays. Non-residents must report every UK property disposal within 60 days, even if no tax is due.

The CGT & landlord tax timeline

Property CGT rates themselves are unchanged for 2026/27, but the wider tax burden on property owners is rising. Here's what's confirmed in the Autumn Budget 2025 and Finance Act 2026.

Now · 2025/26 & 2026/27
CGT property rates held at 18% / 24%
Annual allowance frozen at £3,000 (£1,500 for most trusts). Allowance now confirmed frozen until 5 April 2031 — a real-terms cut as gains continue to grow.
6 April 2026
Business Asset Disposal Relief rate rises to 18%
BADR climbs from 14% to 18%, matching the basic CGT rate. Maximum lifetime saving collapses to roughly £60,000 per person. Owner-managers and landlords with qualifying business activity who can complete before 5 April 2026 lock in the lower rate.
6 April 2026
Making Tax Digital (MTD) live for landlords > £50,000
Sole-trader landlords with rental turnover above £50,000 must keep digital records and submit quarterly updates to HMRC. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028.
6 April 2026
Dividend tax rates rise by 2 points
Basic rate moves to 10.75% and higher rate to 35.75%. Relevant for landlords drawing income from a property limited company.
6 April 2027
Separate, higher tax rates for property income
Rental profits will be taxed at 22% / 42% / 47% — two points above standard income tax rates. Mortgage interest relief (Section 24) will be recalculated at the new 22% basic rate. Also from April 2027, the personal allowance must be set against employment, trading or pension income before property income.
6 April 2028
High Value Council Tax Surcharge ("Mansion Tax")
A new annual surcharge for residential property in England valued above £2 million (based on a fresh Valuation Office assessment). Collected by local authorities; expected to behaviourally bunch sale prices below the £2m threshold.
!
Combined effect for landlords. The OBR notes that successive measures — Section 24, lower CGT allowances, the 5% SDLT surcharge on additional homes, and now the 2% rate uplift on rental income from April 2027 — are reducing private-landlord returns and may push rents up by an estimated £20–£25 per month in England. Many landlords are reviewing whether to incorporate, exit, or restructure.

Legitimate ways to reduce your CGT bill

Transferring a share of the property to a spouse before sale doubles your tax-free allowance to £6,000 and may move part of the gain into the lower 18% band. The transfer itself is CGT-free.
Because CGT rate depends on your other taxable income, completing in a lower-income year (e.g. a sabbatical, pension drawdown gap year, between contracts) can keep more of the gain inside the 18% band.
Solicitor fees on purchase & sale, SDLT paid, estate-agent fees, and capital improvements (with invoices clearly labelled) directly reduce the taxable gain. The distinction between a deductible improvement and a non-deductible repair is one of the biggest sources of overpaid CGT.
If a property has ever been your main home, even for part of the ownership, Private Residence Relief gives partial relief — plus the final 9 months are always exempt. Keep evidence (council tax, electoral roll, utility bills) of the periods of occupation.
Losses on shares, crypto or another property in the same tax year reduce the taxable gain. Reported losses can be carried forward indefinitely — but unreported losses are lost. The deadline to report a loss is 4 years from the end of the tax year it occurred.
Splitting the disposal across two tax years (e.g. a spouse sells their share in March, the other in April) can use two annual allowances in two consecutive years. This requires real ownership transfer and proper conveyancing — not just paperwork.
Limited companies receive full mortgage-interest relief and pay corporation tax (19% / 25%), unaffected by the April 2027 property-rate rise. However, transferring existing properties into a company is itself a CGT disposal and may trigger SDLT. Specialist advice is essential.
Penalties stack quickly. If you can't pin down the final figure, file with your best estimate and amend later through self-assessment. Late-filing penalties usually exceed any CGT recalculation savings.
★
Forward-looking strategy. With landlord rental rates rising in April 2027 and the BADR rate rising in April 2026, some property owners are choosing to dispose of underperforming buy-to-lets before the wider tax burden grows further — using each year's allowance fully rather than holding for marginal gains.

  7. Recording and claiming allowable costs reduces your CGT liability.
  8. Transfers between spouses avoid CGT and allow use of both allowances.
  9. Scottish and Welsh taxpayers face standard CGT rates but different income tax bands affect the rate applied.
  10. Use planning strategies such as timing sales and claiming reliefs to minimize tax due.

This comprehensive insight provides UK taxpayers and property owners with practical knowledge, actionable checklists, and detailed calculations to manage CGT liabilities effectively for the 2025-26 tax year.​

Capital Gains Tax on UK Property Sales 2026

FAQs

Q1: Can someone change their tax code if it’s incorrect when calculating Capital Gains Tax on property sales?

A1: Well, it’s worth noting that CGT on property sales isn’t handled through your tax code like PAYE income tax is. Instead, you report gains and pay CGT separately via the HMRC portal or your self-assessment return. So, an incorrect tax code won’t affect your CGT liability directly, but if you notice discrepancies in your PAYE code that impact your overall income tax band, correcting it could affect the CGT rate you pay on the gain.

Q2: How does having multiple jobs affect the CGT rate on property sales?

A2: In my experience with clients juggling multiple jobs, the key is remembering that your total taxable income (from all jobs) plus your capital gain determines your CGT rate. More income means you’re more likely to pay the higher 24% CGT rate instead of 18%. So double-check all your earnings before calculating CGT to avoid surprises.

Q3: Could a self-employed person in the gig economy face any particular pitfalls with CGT on property sales?

A3: Absolutely. For freelancers or gig economy workers, fluctuating incomes make predicting your CGT rate tricky. Let’s say a contractor in Leeds sells a buy-to-let; a good tip is to estimate your total income including the gain for that tax year to know if you cross the higher rate threshold. Also, keep solid records of all allowable costs to reduce your taxable gain.

Q4: Are there any specific CGT differences for Scottish or Welsh taxpayers on property sales?

A4: It’s a common mix-up, but CGT rates on residential property are UK-wide — 18% for basic rate taxpayers, 24% for higher. However, because income tax bands differ in Scotland and Wales, this affects where your income plus the gain falls in the tax brackets, indirectly influencing your CGT rate. So, always verify your regional income tax bands alongside CGT.

Q5: What happens if a landlord didn’t report a property sale within the 60-day deadline?

A5: Missing the 60-day deadline to report UK residential property sales can lead to penalties and interest. In practice, I advise landlords to file promptly since the penalties start small but grow over time. If you’re late, file as soon as possible and be prepared to explain any genuine reasons for delay to HMRC.

Q6: How can a homeowner with shared ownership reduce CGT on property sales?

A6: For shared ownership, each owner gets their £3,000 annual allowance, doubling it effectively if the property is jointly owned. However, it’s essential to split the gain correctly according to ownership percentages. Also, transferring ownership between spouses before selling can help utilise both allowances fully.

Q7: Is it ever beneficial to gift a property to a spouse before selling to save on CGT?

A7: It can be. Transfers between spouses are CGT-free, which lets you shift the property to utilise both CGT allowances and potentially lower rates. For example, a business owner might gift half the buy-to-let to their spouse, then both sell shares to reduce overall CGT outlay, a strategy I’ve used successfully with married clients.

Q8: Can mixing personal use and rental periods affect CGT liabilities?

A8: Yes, this often trips up many property owners. If your main home was rented out for a period, you might only get partial Private Residence Relief, reducing exempt gain. This means CGT is payable on the gain related to the rental period, so accurate records of dates and usage are crucial.

Q9: How do improvements vs. repairs impact CGT calculation for property sales?

A9: It’s a subtle but vital distinction. Only capital improvements (like extensions or new kitchens) add to your property’s base cost for CGT purposes. Routine repairs or maintenance costs don’t reduce your gain. So, keep invoices sorted and label work carefully.

Q10: What are the chances of HMRC challenging the valuation if a property is sold to a connected party?

A10: Quite high. HMRC expects sales between connected parties to be at market value. If HMRC suspects undervaluation, they may request independent valuation reports or reassess your gain, which can lead to disputes and penalties. Being prepared with professional valuations is a smart safeguard.

Q11: Do pension contributions or withdrawals affect CGT on property sales?

A11: While pension contributions don’t impact CGT directly, higher pension withdrawals can increase your taxable income, potentially pushing you into the higher CGT bracket at 24%. So, if you’re planning a large withdrawal alongside a property sale, it’s wise to plan timing carefully.

Q12: Can an individual with multiple properties sell some without paying CGT?

A12: It depends. Your main residence is generally exempt due to Private Residence Relief. Any extra properties like buy-to-lets or holiday homes will be subject to CGT on gains above the allowance. Strategic timing and using reliefs or exemptions on one property might help.

Q13: How does non-resident CGT reporting differ with multiple UK property sales?

A13: Non-residents must report every UK property disposal within 60 days of completion, even if no CGT is due. This strict reporting ensures HMRC tracks gains accurately. If selling multiple properties in one year, report each separately and keep impeccable records.

Q14: Are there any risks of CGT overpayment if income changes unexpectedly after property sale?

A14: Yes, this happens often with fluctuating incomes — you may calculate CGT assuming a higher tax band than your final income justifies. You can ask HMRC to adjust this via self-assessment amendments or claim a repayment. It’s worth double-checking your final income before submitting.

Q15: If someone receives a family inheritance of property, when does CGT kick in?

A15: Good question. No CGT is due at inheritance. The base cost for CGT is the property value at the date of death. CGT is payable when you later sell the property, with gain measured from the inherited value to the sale price. Careful valuation at inheritance is important.

Q16: What should a PAYE employee check to ensure correct CGT calculations alongside salary?

A16: Employees should check their tax code is correct to ensure income tax bands are properly applied. Since CGT rate depends on combined income, you’ll want your PAYE income accurately reflected so your CGT computation corresponds to your real income level.

Q17: How does the High-Income Child Benefit Charge influence CGT tax planning?

A17: Gains can push your income over £50,000, triggering the high-income child benefit charge, reducing or removing child benefit payments. For business owners with children, this is a subtle trap — planning sales timing or spreading gains over different tax years may help.

Q18: What’s the impact of part-exchanging property on CGT?

A18: Part-exchange means swapping part cash and part another property. For CGT, you calculate gain based on the total value you receive (cash + value of the property received). It complicates calculations, so getting valuations and advice is crucial.

Q19: Can business owners offset CGT from property sales against trading losses?

A19: Unfortunately, no. Trading losses offset income tax, but CGT computations are separate. However, planning to use trading losses in a year with a big capital gain could free up more cash for CGT payments.

Q20: Is it advisable to seek professional valuations for all properties sold?

A20: In my 15+ years advising clients, I always recommend professional valuations, especially for connected-party sales or where the market value is unclear. This protects you from HMRC challenges and supports accurate CGT reporting.
