The UK government has been exploring significant changes to CGT property 2027 rate changes that could fundamentally alter the tax landscape for property investors. While these changes remain under consultation, understanding the potential impact is crucial for landlords planning their investment strategies.

Current speculation suggests that capital gains tax 2027 reforms could align CGT rates more closely with income tax rates, potentially increasing the tax burden on property disposals significantly. This article examines what we know so far and what landlords should be considering.

Current CGT Rates on Property (2025/26)

Before examining potential changes, it's important to understand the current position. For the 2025/26 tax year, CGT on property disposals operates at:

  • 18% for basic rate taxpayers
  • 24% for higher and additional rate taxpayers
  • Annual exempt amount of £3,000

These rates apply to residential property gains, excluding your main residence (which typically qualifies for Private Residence Relief). Commercial property gains are subject to standard CGT rates of 10% (basic rate) or 20% (higher rate).

The key point is that property CGT rates are already higher than standard CGT rates, reflecting the government's policy of treating property investment gains differently from other capital gains.

Proposed CGT Rate Increases from 2027

Government consultation documents and policy papers have suggested several potential approaches to CGT rate increase property taxation from 2027:

Alignment with Income Tax Rates

The most significant proposal involves aligning CGT rates with income tax rates. Under this scenario:

  • Basic rate taxpayers: CGT could increase from 18% to 20%
  • Higher rate taxpayers: CGT could increase from 24% to 40%
  • Additional rate taxpayers: CGT could increase from 24% to 45%

This would represent a substantial increase, particularly for higher and additional rate taxpayers who could see their CGT liability nearly double.

Removal of the Annual Exempt Amount

Another proposal under consideration is the complete removal or further reduction of the annual exempt amount. Having already fallen from £12,300 in 2022/23 to £3,000 in 2025/26, complete removal would mean all gains become taxable.

Changes to Taper Relief

There's speculation about reintroducing taper relief or similar mechanisms that would reduce CGT rates based on the length of ownership. However, this remains uncertain and could work either for or against landlords depending on their holding periods.

Timeline and Implementation

Current government statements suggest any major CGT property 2027 rate changes would be implemented from the 2027/28 tax year (starting 6 April 2027). This timing is significant because it coincides with other major property tax reforms:

  • Separate property income tax rates take effect from April 2027
  • Full implementation of Making Tax Digital for Income Tax
  • Potential changes to Section 24 mortgage interest restrictions

The government has indicated it will provide at least 12 months' notice of any confirmed changes, meaning final decisions would need to be announced by April 2026 at the latest.

Impact on Different Types of Property Investment

Individual Landlords

Individual landlords holding property in their personal names would be most directly affected by rate increases. A landlord disposing of a property with a £100,000 gain could see their tax liability increase from £24,000 to £40,000 (assuming higher rate taxpayer status).

This makes the timing of disposals crucial. Landlords considering selling properties may want to bring forward disposals to 2026/27 to take advantage of current rates.

Limited Company Structures

Properties held within limited companies are subject to corporation tax on gains, not CGT. With corporation tax rates at 19% (small profits rate) and 25% (main rate), company structures might become more attractive if personal CGT rates increase significantly.

However, extracting gains from companies through dividends or capital distributions creates additional tax layers that need careful consideration. Our guide to buy-to-let limited companies explores these structures in detail.

Joint Ownership

Married couples and civil partners who jointly own properties could use their combined annual exempt amounts and potentially manage gains across different tax years to optimise their position under current rules.

Planning Strategies for 2027 Changes

Timing of Disposals

The most immediate consideration for many landlords is whether to accelerate property disposals before the 2027 changes take effect. This strategy might be appropriate if:

  • You were already planning to sell within the next 3-4 years
  • Properties have accumulated substantial gains
  • You're a higher or additional rate taxpayer

However, premature disposals purely for tax reasons can be counterproductive if it disrupts your investment strategy or forces sales in unfavourable market conditions.

Incorporation Considerations

If CGT rates increase substantially while corporation tax rates remain relatively stable, incorporation might become more attractive for some landlords. However, this needs to be weighed against:

  • Ongoing compliance costs and complexity
  • Loss of mortgage interest relief benefits
  • Potential incorporation charges if transferring existing properties

Gift and Inheritance Planning

Higher CGT rates could make gift planning more complex. While gifts between spouses remain tax-neutral, gifts to adult children or trusts could trigger larger CGT liabilities if rates increase.

Some landlords might consider gifting properties before 2027 to take advantage of current rates, though this needs careful planning around inheritance tax implications and loss of control.

Commercial vs Residential Property

The proposed changes appear focused on residential property CGT rates. Commercial property gains might remain subject to standard CGT rates (currently 10%/20%), potentially making commercial property investment relatively more attractive from a tax perspective.

However, commercial property investment carries different risks and requires different expertise compared to residential buy-to-let investment.

Interaction with Other Tax Changes

The capital gains tax 2027 changes don't exist in isolation. Landlords need to consider them alongside:

Separate Property Income Tax Rates (April 2027)

From April 2027, property income will be subject to separate tax rates (22%/42%/47% instead of standard income tax rates). Combined with higher CGT rates, the overall tax burden on property investment could increase significantly.

Section 24 Restrictions

The Section 24 mortgage interest restrictions continue to limit tax relief on mortgage interest to the basic rate. Higher CGT rates could compound the impact of these restrictions.

Making Tax Digital Requirements

Making Tax Digital for Income Tax becomes mandatory from April 2026 for landlords with gross rental income over £10,000. This adds compliance complexity just as the tax landscape becomes more challenging.

What Landlords Should Do Now

Review Your Portfolio

Conduct a comprehensive review of your property portfolio, including:

  • Estimated gains on each property based on current values
  • Your likely tax position in 2027 and beyond
  • Properties you might consider disposing of in the next few years
  • The impact of different CGT rate scenarios on your plans

Consider Professional Advice

The complexity of these potential changes and their interaction with existing rules makes professional advice increasingly valuable. A specialist property accountant can help model different scenarios and develop appropriate strategies.

Stay Informed

Tax policy in this area remains fluid. The government's final decisions may differ from current proposals, and implementation details could significantly affect the practical impact.

Subscribe to updates from HMRC and professional bodies, and consider how different outcomes might affect your investment strategy.

Don't Make Hasty Decisions

While it's important to plan for potential changes, avoid making irreversible decisions based on speculation. The proposals remain under consultation, and final policy may look different from current suggestions.

Wider Market Implications

Significant increases in property CGT rates could have broader market implications:

  • Reduced liquidity: Higher exit taxes might encourage longer holding periods
  • Price impacts: Buyers might adjust offers to reflect higher future tax costs
  • Investment flows: Capital might shift towards other asset classes or offshore opportunities
  • Structural changes: Greater use of corporate structures and alternative investment vehicles

Understanding these potential market-wide effects is important for long-term investment planning.

International Perspective

For non-resident landlords, the interaction between UK CGT changes and their home country tax systems could become more complex. Higher UK CGT rates might affect the value of double taxation treaty relief and influence decisions about UK property investment.

The UK's approach to property CGT rates would also affect its competitiveness as an international investment destination compared to other major property markets.

Keeping Your Options Open

Given the uncertainty around final policy details and implementation, the best approach for most landlords is to:

  • Understand the range of possible outcomes
  • Identify which scenarios would most affect your situation
  • Develop flexible strategies that can adapt to different outcomes
  • Monitor developments and be ready to act when details become clearer

The CGT property 2027 rate changes represent potentially the most significant shift in property taxation for a generation. While the full impact remains unclear, early preparation and professional guidance will be essential for navigating these changes successfully.
