What is Capital Gains Tax?
For many, property investment represents a significant pathway to achieving consistent and substantial returns. Investment property remains a resilient asset class, offering diverse opportunities. However, navigating the UK property investment landscape requires a thorough understanding of the associated taxes, which can significantly impact your profitability.
Capital Gains Tax (CGT) is a crucial consideration for property investors, particularly those focused on shorter-term investments or planning to liquidate their portfolio for a lump sum. CGT is levied on the profit (or gain) realised when you sell an asset that has increased in value, directly affecting your overall investment returns. This guide will provide you with the most up-to-date information on capital gains tax on investment property in 2025.
How Capital Gains Tax Works on Investment Property in the UK
It’s important to understand that CGT isn’t exclusive to property; it applies to gains from a wide range of investments, from stocks and shares to investment property. If you make a profit from selling a buy-to-let property or any other investment asset, this profit may be subject to Capital Gains Tax.
Capital Gains Tax Allowance: What You Need to Know for 2025
The amount you can earn in profits before paying CGT has changed in recent years. For the tax year 2024/2025, the Capital Gains Tax allowance is £3,000. This means that if your investment property gains are below this threshold, you will not pay CGT. However, if your gains exceed this personal allowance, you will be taxed on the profit above £3,000.
Example:
If you sell your investment property and make a profit of £30,000, you will only pay Capital Gains Tax on £27,000 (£30,000 – £3,000 allowance). The actual tax rate you pay will depend on your Income Tax band.
Capital Gains Tax Rates for Investment Property in 2025
Significant changes to Capital Gains Tax rates came into effect in 2024 and further changes are scheduled for 2025 and 2026. For disposals of investment property (residential property) made on or after October 30, 2024:
- Basic Rate Income Taxpayers: The CGT rate is 18% (increased from 10%).
- Higher or Additional Rate Income Taxpayers: The CGT rate is 24% (increased from 20%).
These increased rates mean that understanding your income tax band is crucial for calculating your potential capital gains tax liability on investment property.
You can find more detailed information on these rate changes on the GOV.UK website.
When Do You Pay Capital Gains Tax on Investment Property?
The timing of CGT payment is important for property investors.
- Long-term Rental Income vs. Property Flipping: If your investment strategy focuses on long-term rental income, CGT may be less of an immediate concern. However, if you are building a portfolio to sell for a lump sum or are involved in property flipping, CGT becomes a primary consideration.
- Payment Trigger: CGT is payable upon the sale of your investment property, once you have calculated your profit.
- Reporting Deadlines: For gains made on residential property disposals on or after April 6, 2020, you must report the gains to HMRC and pay the CGT within 60 days of the sale completion. This is a change from the previous 30-day reporting window. For gains made before April 2020, you can report these via your Self Assessment tax return.
Capital Gains Tax on Inherited Property
Inheriting property can be complex from a tax perspective. If inheriting a property results in you owning multiple properties, you’ll need to designate one as your primary residence. When you sell any property that is not your primary residence (including inherited investment property), you will be liable for Capital Gains Tax on any profit made from the sale.
If you wish to mitigate CGT on inherited property, consider renting it out instead of selling. This can provide a consistent income stream without triggering an immediate CGT liability.
Calculating Capital Gains Tax on Investment Property
To accurately calculate your capital gains tax on investment property, you need to determine your profit and your Income Tax band.
Example Calculation (using updated 2025 rates and £3,000 allowance):
Let’s assume you are a higher rate Income Taxpayer and make a £150,000 profit on selling your residential investment property.
- Taxable Gain: £150,000 (Profit) – £3,000 (Personal Allowance) = £147,000
- Capital Gains Tax Calculation:
- Higher/Additional Rate Taxpayer (24% CGT): £147,000 x 24% = £35,280
Therefore, in this scenario, a higher rate taxpayer would owe £35,280 in Capital Gains Tax.
Capital Gains Tax for Overseas Investors
Overseas investors with investment property in the UK are also subject to Capital Gains Tax. The same rates of 18% or 24% apply. However, there are specific reliefs available for overseas investors.
- Principal Private Residence Relief: Overseas investors may be able to claim Principal Private Residence Relief if they have occupied the property as their main residence. To qualify, they typically need to reside in the property for a significant period (rules can be complex, so professional advice is recommended).
- Tax Residency Implications: Be aware that spending a significant amount of time in the UK to claim this relief could potentially impact your UK tax residency status, potentially incurring other UK taxes.
