With potential Labour government housing policies post-2024, what are the likely impacts on capital gains tax (CGT) for buy-to-let property sales and Section 24 mortgage interest relief by 2026, and how can investors mitigate these changes?
Quick Answer
Potential Labour policies post-2024 may increase CGT on property sales and maintain or tighten Section 24 for landlords, impacting profitability.
## Navigating Potential Capital Gains Tax and Section 24 Changes
### What are the current Capital Gains Tax rates on residential property?
Current Capital Gains Tax (CGT) on residential property for basic rate taxpayers is 18%, while higher and additional rate taxpayers face a 24% rate. Investors can use an annual exempt amount, currently £3,000, to reduce their taxable gains. For example, a higher rate taxpayer selling a property with a £50,000 gain would pay £11,280 in CGT after deducting the exempt amount, representing a significant cost that directly reduces investment returns.
### How might CGT rates change under a potential Labour government?
A potential Labour government might increase CGT rates or reduce the annual exempt amount further. While specific proposals could emerge, investors should consider a scenario where CGT rates align more closely with income tax rates. This would mean higher/additional rate taxpayers potentially facing a CGT rate of 40% or 45%, similar to their income tax bands. Such a change would significantly affect long-term profit projections for buy-to-let property sales. For instance, a £100,000 gain currently taxed at 24% (less the £3,000 exemption) would cost £23,280 in CGT; at 40%, this jumps to £38,800.
### Will Section 24 relief be reinstated or further restricted?
Section 24, which removed the ability for individual landlords to deduct mortgage interest from rental income, was fully phased in by April 2020 and is highly unlikely to be reinstated under any government. Instead, there is potential for further restrictions or amendments that could impact the remaining mortgage interest relief, currently given as a 20% tax credit. For example, a landlord with £10,000 of mortgage interest receives a £2,000 tax credit. Scenarios could involve capping this credit or reducing its percentage, directly increasing the effective tax burden on rental income and reducing net profitability for landlords with mortgages. The current Bank of England base rate of 4.75% contributes to higher mortgage interest payments, making any further Section 24 restrictions particularly impactful for landlords with BTL mortgage rates typically between 5.0-6.5%.
### What strategies can mitigate potential CGT increases?
To mitigate potential CGT increases, investors can consider holding properties within a limited company, where Capital Gains Tax does not apply directly. Instead, any profits on disposal are subject to Corporation Tax, currently 19% for profits under £50k and 25% for profits over £250k. Another strategy involves exploring other property investment opportunities that may have more favourable tax treatments or are less susceptible to direct CGT changes, such as commercial property, which has different CGT rules. Landlords could also consider crystallising gains before potential policy changes are enacted, although this is speculative and depends on individual circumstances and market conditions. Thorough financial planning and scenario analysis for "BTL investment returns" against various tax impacts are crucial.
### How can investors manage Section 24 impacts?
Managing Section 24 impacts primarily involves strategies to reduce reliance on mortgage finance or optimise property ownership structures. Incorporating as a limited company allows full mortgage interest deduction against rental income before Corporation Tax, a significant advantage over individual ownership. However, transferring properties to a limited company can incur Stamp Duty Land Tax (SDLT) and CGT liabilities, so this requires careful financial modelling. Investors should focus on maximising rental income while minimising operational expenses to strengthen their "landlord profit margins". Reviewing existing mortgage products and stress-testing portfolios against varying interest rates and Section 24 scenarios is also advisable. For example, a property generating £1,200/month rent with £700/month mortgage interest would yield a pre-tax profit of £500 as a limited company, but much less as an individual taxpayer due to Section 24.
Steven's Take
The potential for increased CGT and tightened Section 24 reinforces the need for strategic property structuring. While political changes can create uncertainty, the core principles of sound property investment remain. For many, transitioning to a limited company structure has already proven beneficial for rental income and mortgage interest deductions. Reviewing your portfolio and understanding your true 'rental yield calculations' against various tax implications is not about reacting to speculation, but about building resilience. Always make decisions based on what makes commercial sense for your long-term goals.
What You Can Do Next
Review your current property ownership structure (individual vs. company): Consult a property tax specialist accountant (search 'property tax accountant' on ICAEW.com) to understand the benefits and costs of holding properties in a limited company, including potential SDLT and CGT implications on transfer.
Calculate your current and potential future CGT liability: Use the HMRC CGT calculator (gov.uk/tax-sell-property/work-out-your-gain) to model scenarios with increased rates and reduced annual exemptions for your existing portfolio.
Stress-test your cash flow against Section 24 changes: Create a detailed income and expenditure spreadsheet for each property, factoring in potential reductions to the 20% mortgage interest tax credit, to assess the impact on your 'landlord profit margins' and overall portfolio resilience.
Stay informed on policy developments: Monitor official government and reputable property industry news sources (e.g., LandlordZone.co.uk, NRLA.org.uk) for specific proposals related to CGT and Section 24, ensuring decisions are based on confirmed information.
