Capital Gains Tax UK: Rates, Thresholds & Avoidance 2026

Capital Gains Tax in the UK changed significantly from 6 April 2026, with higher-rate taxpayers now facing 24% on residential property gains — up from previous years. Understanding the 18%/24% rate structure, annual exemption of £3,000, and legal relief options before selling beats discovering a large tax bill afterwards.

Basic rate CGT: 18% · Higher rate CGT from 6 April 2026: 24% · Annual exempt amount: £3,000 · Property reporting deadline: 60 days

The following table summarises the key figures every UK property seller needs to know heading into 2026/27.

What is the Capital Gains Tax rate in the UK?

Understanding UK CGT rates matters because the difference between 18% and 24% on a £100,000 gain is £6,000. The rates apply differently depending on your total taxable income, the type of asset sold, and whether you qualify for any reliefs.

“The following Capital Gains Tax rates apply: 18% and 24% for individuals from 6 April 2026.” — HMRC, UK Government Tax Authority

Basic rate taxpayers

If your total taxable income falls within the basic rate band (currently £12,570 to £50,270 for 2025/26), your CGT on most assets is charged at 18%. This applies to gains on shares, crypto, and residential property alike. According to GOV.UK’s guidance on capital gains tax rates and allowances, this rate covers individuals who have not exceeded their basic rate threshold.

Higher and additional rate taxpayers

Once your total taxable income pushes past the higher rate threshold, your CGT jumps to 24% on gains above that band. This applies from 6 April 2026 for all residential property and most other assets. Analysis from Headway Wealth (a wealth management advisory) confirms that the 2026/27 rates remain 18% within the basic band and 24% above for residential property.

Property vs other assets

Post-October 2024, rates harmonised at 18%/24% for most assets including property. According to Prosperity Group (a wealth management firm), this alignment removed the previous discrepancy where residential property had faced higher rates. Carried interest remains an exception, taxed at 32% for the period 6 April 2025 to 5 April 2026, per GOV.UK.

How can I avoid paying Capital Gains Tax on property in the UK?

Legal CGT avoidance isn’t about loopholes — it’s about understanding which reliefs you’re entitled to and structuring your disposal to maximise them. Several strategies stand out based on current rules.

Use annual exemption

Every individual gets a £3,000 annual exempt amount for 2026/27 per GOV.UK. Couples with jointly owned property can combine exemptions for £6,000 of tax-free gain. One approach is timing property sales across different tax years to use multiple exemptions, as explained by MMBA Accountants (a chartered accountancy firm).

Private Residence Relief

PRR eliminates or reduces CGT on your main home sales. The final 9 months of ownership are automatically exempt even if the property was not your main home throughout, according to MMBA Accountants. The relief applies if the property was your primary residence at any point during ownership — this matters for those who have lived in an investment property before selling it.

Transfer to spouse

Transfers of property to a spouse or civil partner are CGT-free if genuinely gifted. This allows use of both partners’ annual exemptions. Analysis from GoldHouse Accounting (an accounting practice) notes that the transfer must be genuine to avoid HMRC challenge — gifts at undervalue still trigger CGT calculations based on market value.

What is the 6-year rule on Capital Gains Tax?

The 6-year rule specifically applies to absent UK property owners — UK residents who left the country but retained property here. Understanding who qualifies matters because the implications for non-resident landlords are significant.

Eligibility

The 6-year rule applies to individuals who have left the UK and own property that was either their main home or a property they had lived in. According to Experts for Expats (a specialist expat tax advisory), non-residents face the same CGT rates on UK residential property: 18% basic and 24% higher rate.

How it works for non-residents

When a non-resident sells UK property, they must report and pay CGT within 60 days of completion, per Experts for Expats. This 60-day reporting requirement is strict — missing the deadline incurs penalties. The rule essentially limits private residence relief for periods the owner was not living in the property.

Time limits

PRR can cover periods when the property was the owner’s main home, plus the final 9 months of ownership. The 6-year reference typically relates to how long a previous main home can still qualify for relief if it was rented out — but specific timing depends on the individual’s circumstances and HMRC’s detailed calculations.

How much before I pay Capital Gains Tax in the UK?

CGT isn’t charged on the full sale price — it’s calculated on the profit (gain) after allowable deductions. Several thresholds and calculators help you estimate liability before you sell.

Annual threshold

The annual exempt amount is £3,000 for 2026/27, confirmed by THP Chartered Accountants (a chartered accountancy practice). This means gains up to £3,000 are tax-free per individual. Gains above this amount are added to your total income for the tax year to determine which CGT band applies.

Calculator tools

Several providers offer CGT calculators based on GOV.UK rates. MMBA Accountants recommends using official tools to model different scenarios, particularly around timing sales across tax years. The key inputs are your estimated total income for the tax year, the gain amount, and any allowable expenses.

Income tax band impact

Your CGT rate depends on where your total income falls. If your taxable income (including the gain) exceeds £50,270, the portion of gain above that threshold faces 24% CGT. This crossover effect means a £30,000 gain on top of a £45,000 salary could push part of the gain into the higher CGT band.

Can I avoid Capital Gains Tax in the UK?

Complete avoidance is rarely legal, but significant reduction is achievable through recognised reliefs, wrappers, and timing strategies. The key distinction is between tax avoidance (illegal) and tax planning (legal).

Legal reliefs and exemptions

PRR, the annual exemption, lettings relief (up to £40,000 where applicable), and chattels exemption (£6,000 per item) are all legitimate. MMBA Accountants (chartered accountancy firm) confirms these are statutory reliefs HMRC allows — not loopholes.

Pension and ISA wrappers

Assets held within an ISA or pension are exempt from CGT. The “Bed and ISA” strategy — selling an asset outside an ISA, waiting, then repurchasing within an ISA — is mentioned by MMBA Accountants as a method to shelter future gains. However, this requires careful timing to ensure the disposal and repurchase are genuinely separate transactions for CGT purposes.

Timing disposals

Spreading sales across different tax years allows use of multiple annual exemptions. If your income fluctuates, selling in a lower-income year may keep more of the gain within the basic rate CGT band. St. James’s Place (a financial advisory firm) notes that planning ahead of the 6 April year-end is particularly valuable given the rate changes.

UK Capital Gains Tax for non-residents: Rules and rates

Non-residents selling UK property face the same rates as UK residents but with additional reporting obligations. Understanding the rules matters because the 60-day deadline is unforgiving.

Same rates apply

According to Experts for Expats, non-residents pay 18% CGT within the basic rate band and 24% above for UK residential property. There is no special lower rate for non-resident sellers. The rules apply from 6 April 2026 with the same harmonised rates as UK residents.

Reporting requirements

Non-residents must register with HMRC and report UK property disposals within 60 days of completion. This is a strict deadline — late filing incurs penalties regardless of whether tax was paid on time. Experts for Expats (expat tax specialist) advises that non-residents without a UK tax adviser should seek professional help given the complexity.

The 6-year absenc

Non-residents who previously lived in the UK may still qualify for PRR on a former main home under certain conditions. The rule relates to periods of absence and whether the property was genuinely the owner’s main residence at any point. Documentation of occupancy periods is essential for any PRR claim.

Capital Gains Tax UK shares and crypto rates

CGT on investments and digital assets follows the same 18%/24% rates as property from 6 April 2026. The rules apply whether you’re selling shares, funds, or cryptocurrency.

Shares and funds

According to Prosperity Group, crypto profits and business assets including shares are subject to CGT at standard rates. The gain is calculated as sale proceeds minus purchase price and allowable expenses. Using the annual exemption and ISA wrappers are the primary legal reduction strategies.

Cryptocurrency

Crypto assets are treated as chargeable assets for CGT purposes. Gains from crypto disposals are added to total taxable income to determine the applicable rate. Prosperity Group (wealth management firm) confirms that all crypto profits are subject to CGT — there is no specific exemption or lower rate for digital assets.

Using ISAs for shares

Holding shares within an ISA removes them from CGT entirely. MMBA Accountants recommends maximising ISA allowances (£20,000 per year in 2025/26) before holding investments outside the wrapper. For long-term investors, the compounding benefit of CGT-free growth is substantial.

The 36-month rule and main residence elections

Two lesser-discussed rules affect CGT on residential property: the 36-month rule for PRR and the split-year election for those with multiple residences.

The 36-month rule explained

When a property was the owner’s main residence at any point, PRR applies for that period plus an additional 36 months after it ceased being the main home. According to HMRC guidance confirmed by MMBA Accountants, this provides a buffer period for those who move out before selling. The final 9 months of ownership receive automatic PRR regardless of occupancy.

Main residence elections

Those with more than one property can make an election to designate one as their main residence for PRR purposes. GoldHouse Accounting notes that this election can be changed during ownership but requires careful analysis of which property would generate the larger gain if sold.

Split-year strategies

For those moving between properties, split-year treatment may allow PRR across both in the same tax year. Samuel Leeds (property investor and training provider) discusses the live-in strategy — moving into an investment property, renovating, and selling as the main residence to claim PRR. This requires genuine occupancy and HMRC scrutiny of the timing.

How to reduce Capital Gains Tax in 2026

With rates at 18%/24% from 6 April 2026, the window for certain reduction strategies narrows. Here’s what remains viable.

Enterprise Investment Scheme

EIS allows deferral of CGT on property sales by reinvesting in qualifying unlisted companies. Per MMBA Accountants, this requires the reinvestment to be in EIS-qualifying shares and the deferral applies to gains from other assets. The original gain is not eliminated — just deferred until the EIS shares are sold.

Refurbishment costs

Deducting improvement and refurbishment costs from the taxable gain is legitimate and often overlooked. GoldHouse Accounting confirms that capital expenditure on property improvements — but not repairs — reduces the chargeable gain. Keeping detailed records of renovation costs is essential.

Trust structures

According to Haggards Crowther (a chartered accountancy practice), trusts and estates can be used to structure ownership for CGT reduction. However, trustees pay a flat 24% on all residential property gains from 6 April 2026 — the same as higher-rate individuals. The structure benefit depends on individual circumstances and requires professional advice.

Summary

The 2026 CGT changes mark a significant shift for UK property investors and higher-rate taxpayers. Rates harmonised at 18%/24% from 6 April 2026 mean the previous preferential treatment for residential property is gone. The annual exempt amount of £3,000 per person remains the first line of defence, while PRR, spousal transfers, and ISA wrappers offer legitimate reduction strategies. The 60-day reporting deadline for property sales applies to both residents and non-residents — a compliance trap for the unprepared. Property sellers who understand the rates, reliefs, and timing options before disposing of assets will fare better than those who discover their CGT liability after completion.
