Capital Gains Tax Considerations for Property Investors and Business Owners in the UK
With property prices in London and across the UK continuing to fluctuate, many investors and business owners face significant Capital Gains Tax bills upon selling assets. A surprising fact is that the annual tax-free allowance stands at just £3,000 for the 2025/26 and 2026/27 tax years, meaning even modest gains can trigger a tax liability at rates of up to 24 percent.

Introduction:
Capital Gains Tax considerations for property investors and business owners play a crucial role in effective financial planning across London and the wider UK. Whether you are selling a buy-to-let property, disposing of commercial premises, or exiting a business, understanding CGT rules helps you stay compliant while maximising your returns. At Kay Peters & Co, with decades of experience supporting clients since 1978, we provide clear, practical guidance tailored to your circumstances, helping you navigate these rules with confidence.
What Is Capital Gains Tax and Who Does It Affect?
Capital Gains Tax is the tax payable on the profit, or gain, made when you dispose of an asset that has increased in value. This includes selling, gifting, or transferring property and certain business assets. Property investors, such as landlords with buy-to-let portfolios, and business owners disposing of premises or shares typically fall within its scope.
Individuals, sole traders, and partners in businesses pay CGT through self-assessment, while limited companies pay Corporation Tax on gains instead. Accurate record-keeping of purchase costs, improvement expenses, and sale proceeds is vital for correct calculations.
Current CGT Rates and Allowances
For the 2025/26 tax year, the annual exempt amount is £3,000 for individuals. This means you only pay tax on gains exceeding this threshold.
Residential property gains are taxed at 18 percent for basic rate taxpayers and 24 percent for higher or additional rate taxpayers. Similar rates generally apply to other assets following recent changes. Rates for Business Asset Disposal Relief are scheduled to increase, reaching 18 percent from April 2026 for qualifying disposals.
Always consider your total income, as it determines which tax band your gains fall into.
Capital Gains Tax for Property Investors
Property investors must account for CGT on second homes, buy-to-let properties, and commercial real estate. Key deductible expenses include the original purchase price, stamp duty, legal fees, and capital improvement costs, such as extensions or renovations, but not routine maintenance.
Private Residence Relief (PRR):
If a property has been your main home for part of the ownership period, you may claim partial relief. The final nine months of ownership are usually treated as a residence period, regardless of actual use.
Reporting Requirements:
For UK residential property disposals, you must report and pay any CGT due within 60 days of completion using the dedicated HMRC service. Missing this deadline can result in penalties.
CGT Considerations for Business Owners
Business owners face additional layers. Sole traders and partnerships pay CGT on asset disposals, while companies handle gains via Corporation Tax. Selling business premises or shares in a trading company may qualify for reliefs that significantly reduce the effective rate.
Business Asset Disposal Relief (BADR):
This relief allows qualifying gains up to a £1 million lifetime limit to be taxed at a lower rate, currently 10 percent or 14 percent depending on the timing, rising to 18 percent from 2026. Strict conditions apply, such as owning at least 5 percent of shares and meeting employment criteria.
Other options include rollover relief, where gains are deferred by reinvesting in new qualifying business assets.
Strategies to Minimise Capital Gains Tax
Effective planning can make a substantial difference:
- Transfer assets to a spouse or civil partner to utilise their annual allowance and lower tax bands (transfers between spouses are usually CGT-free).
- Time disposals to spread gains across tax years.
- Consider holding property within a limited company, though this involves weighing Corporation Tax and other factors.
- Claim all allowable expenses and reliefs, and maintain detailed records.
- Explore hold-over relief for gifts of business assets.
Professional tax planning, tailored to your situation, ensures you remain compliant while optimising outcomes.
Common Pitfalls to Avoid
Failing to report within 60 days, underestimating deductible costs, or overlooking mixed-use properties can lead to unexpected liabilities and penalties. Non-residents and those with complex structures face additional rules. Early advice prevents costly mistakes.
Conclusion:
Capital Gains Tax considerations for property investors and business owners demand proactive planning to protect your wealth and support sustainable growth. By understanding rates, reliefs, and reporting obligations, you can make informed decisions that align with your long-term goals. Key takeaways include utilising the £3,000 annual exemption, maximising available reliefs such as PRR and BADR, and keeping thorough records.
