What the proposed capital gains changes are in the uk autumn budget 2026
The main rates of capital gains tax stay at 18 percent for basic-rate taxpayers and 24 percent for higher-rate taxpayers. The annual exempt amount remains £3,000. The real shift sits in the reliefs. Business Asset Disposal Relief lifetime limit falls from £1 million to £500,000 for disposals on or after 6 April 2027. A new Founders’ Relief offers a 10 percent rate on up to £10 million of lifetime gains for qualifying founders and early investors in high-growth innovative companies, subject to strict conditions and a technical consultation that closed on 30 November 2026.
Full details appear in the official Budget 2026 collection published by HM Treasury. Advisers note that the Founders’ Relief is unlikely to help most residential landlords because property development and land dealing sit outside the qualifying activities.
How the reform applies to residential property disposals
Residential property gains continue to be charged at the same main rates. No private residence relief changes were announced for ordinary buy-to-let stock. The reduction in the BADR lifetime limit affects any landlord who also holds shares in a trading company and had planned to use the higher allowance on an exit. RSM UK and other firms have highlighted that the combined package could still raise material revenue through behavioural effects and the property income tax rise rather than through higher CGT rates themselves.
How the new rules will be implemented and interact with existing tax law
The BADR cut and Founders’ Relief both take effect from 6 April 2027. Until that date the existing rules apply. Reporting of UK residential property disposals remains due within 60 days of completion, with the gain also entered on the Self Assessment return. Late-filing penalties on the property disposal return stop accruing once the disposal is reported on the Self Assessment return, a small administrative relief that starts from Budget day itself.
Stamp duty land tax and the capital gains regimes continue to operate side by side. Group relief claw-back rules were tightened so that winding up the vendor company no longer prevents recovery of the relief if the purchaser leaves the group within three years. Trustees and personal representatives face the same valuation and reporting deadlines as individuals.
How valuation and reporting will work under the new regime
Valuation for CGT purposes remains the market value at the date of disposal. HMRC has not altered the 60-day reporting window. Landlords who hold properties through companies must still consider how corporation tax on chargeable gains interacts with the new property income tax rates that apply to individuals from April 2027. Accurate contemporaneous records of acquisition costs, improvement expenditure and selling costs remain essential.
Why John Healey and ministers are pushing capital gains reform now in the UK budget 2026
John Healey framed the autumn budget as providing breathing space while protecting the fiscal rules. Pre-Budget speculation had focused on aligning CGT rates with income tax. The Chancellor rejected that route after warnings that higher rates could reduce overall receipts through deferred sales and migration. Instead, the package targets reliefs and property income. Concurrent measures such as the uk car tax changes 2026 — Vehicle Excise Duty rising with RPI from April 2027 and the planned electric vehicle mileage charge from 2028 — sit in the same fiscal narrative of revenue stability and green transition.
How fiscal pressure and autumn budget predictions shaped the policy choice
Autumn budget 2026 predictions gov uk commentary and market notes had widely expected a CGT rate rise. The final autumn budget summary shows the government chose a narrower route. The Office for Budget Responsibility forecasts incorporate the behavioural response to the relief changes and the additional property income tax yield. The legislative timetable runs through the Finance Bill 2026-27, with most personal tax measures commencing in the 2027-28 tax year.
What changes for property investors, landlords and small-scale developers
Cash flow is the immediate pressure point. From 6 April 2027, the rates of income tax on property income rise by a further two percentage points to 24 percent, 44 percent and 49 percent. That increase compounds the earlier rise and reduces net rental yields for higher-rate landlords. Sale timing decisions now hinge on the BADR limit reduction rather than on any change to the main CGT rates. Portfolio structures that rely on incorporation or trust arrangements need fresh modelling because the interaction with the higher income tax rates alters the relative advantage of each vehicle.
Transaction costs stay largely unchanged. SDLT rates were not altered. The main practical consequence is the need to update cash-flow forecasts and to review any planned disposals that might have used the higher BADR allowance.
1. Check the projected completion date of any planned sale against the 6 April 2027 BADR threshold.
2. Review whether existing company or trust structures still deliver the expected after-tax return once the higher property income rates apply.
3. Update portfolio valuations and acquisition cost records so that any future CGT computation is accurate.
4. Seek tailored advice on whether a pre-April 2027 disposal could preserve access to the higher BADR limit.
5. Model the cash-flow impact of the additional two-point property income tax rise on each let property.
6. Document improvement expenditure and selling costs in contemporaneous form to support future claims.
How a sale of a buy-to-let property could be taxed differently
A straightforward disposal of a residential buy-to-let by an individual still attracts CGT at 18 percent or 24 percent after the £3,000 annual exempt amount. The difference appears only if the seller also claims Business Asset Disposal Relief on other assets and has already used a substantial part of the lifetime limit. In that case the halved allowance from April 2027 can push more of the gain onto the main rates. For pure property investors, the headline CGT outcome is unchanged; the larger hit arrives through the higher tax on rental income while the asset is held.
What comes next: legislative timetable, consultation and market reaction
The Finance Bill 2026-27 will contain the detailed clauses. Founders’ Relief remains subject to the technical consultation responses. Industry bodies and firms such as Stephenson Harwood have published detailed notes on the interaction of the new relief with existing CGT rules. Market reaction has been muted on the residential side because rates themselves did not rise, yet landlords continue to reassess yields in light of the property income tax increase.
When will the measures reach Parliament and become law: anchor in the fiscal calendar
The uk autumn budget 2026 date was 28 October 2026. Most of the personal tax measures take effect from 6 April 2027. Readers should confirm the precise commencement dates against the official parliamentary calendar and the final Finance Act text before acting on any disposal plans.
Final verdict
The capital gains reform package does not raise the main rates that apply to residential property. The practical pressure on property investors comes from the reduced BADR lifetime limit and, more immediately, from the additional two-point rise in property income tax. Landlords with simple portfolios face higher ongoing tax on rents; those with mixed business and property holdings may lose part of the previous relief capacity. Industry estimates suggest the largest disruption falls on higher-rate landlords who planned to rely on the full £1 million BADR allowance.

FAQ
How will capital gains reform affect my buy-to-let property?
The main CGT rates that apply when you sell a buy-to-let remain 18 percent or 24 percent. Private residence relief is unchanged for ordinary lettings. The practical difference appears only if you also use Business Asset Disposal Relief on other assets and the reduced lifetime limit from April 2027 leaves less headroom. Ongoing tax on rental income rises by two percentage points from the same date, which reduces net cash flow while you continue to hold the property.
When is the autumn budget 2026 uk and when will changes take effect?
The autumn budget took place on 28 October 2026. That is the confirmed uk autumn budget 2026 date. Most of the personal tax measures, including the BADR limit reduction and the further property income tax rise, take effect from 6 April 2027. Always cross-check the final Finance Act and the official parliamentary calendar before relying on any specific commencement date.
What are the risks if I delay selling property until after the autumn budget?
Because the main CGT rates did not rise, the pure rate risk of waiting past 28 October 2026 is limited. The larger risk is the 6 April 2027 BADR threshold. Any disposal completed after that date can only use the lower £500,000 lifetime limit. Cash-flow risk also rises because the higher property income tax rates begin to apply from the same day, so net rental receipts fall while you continue to hold the asset.
Do I need to change my company or trust structure because of the capital gains reform?
Restructuring is not automatic. Review the numbers if the higher property income tax rates make personal ownership less attractive relative to a company, or if the reduced BADR limit affects a planned exit that mixes shares and property. Governance and reporting burdens increase with any new structure. Seek tailored advice before moving assets; the cost of restructuring can outweigh the tax saving if the numbers are marginal.
