When it comes to selling property in the UK, one of the biggest financial considerations is Capital Gains Tax (CGT) — the tax charged on the profit you make when disposing of an asset that has increased in value. Whether you’re selling a buy-to-let, a second home, or an inherited property, understanding how to legally reduce or avoid Capital Gains Tax can save you thousands of pounds.
In this detailed guide, ABM Chartered Accountants, a leading UK accountancy firm, explains how CGT works, who it applies to, and what steps you can take to minimise your liability — all while staying fully compliant with HMRC rules.
What Is Capital Gains Tax on Property?
Capital Gains Tax (CGT) is a tax on the profit (or “gain”) made when you sell an asset for more than you paid for it. In the case of property, the tax applies when selling or disposing of:
- A second home
- A buy-to-let investment property
- A property inherited and later sold
- A commercial property
Your main home is usually exempt from CGT, thanks to Private Residence Relief, but other types of property sales may be taxable.
CGT Rates for Property in 2026
As of the 2025/26 tax year, property CGT rates are:
- 18% for basic rate taxpayers
- 28% for higher and additional rate taxpayers
The amount you pay depends on your total taxable income and capital gains for the year.
1. Claim Private Residence Relief (PRR)
If the property you’re selling has been your main home, you can claim Private Residence Relief. This relief can exempt all or part of your gain from CGT.
Eligibility criteria:
- You must have lived in the property as your main home.
- You cannot have rented it out (except for a permitted lodger).
- You must not have used the property entirely for business purposes.
Example:
If you lived in the property for 10 years and rented it out for 5 years before selling, you can claim partial PRR for the 10 years of residence — and may also qualify for Lettings Relief on the remainder.
2. Use Your Annual CGT Allowance
Every individual in the UK has a Capital Gains Tax allowance, also known as the Annual Exempt Amount (AEA).
For the 2025/26 tax year, the allowance is £3,000 per person (subject to HMRC updates).
If you own a property jointly with a spouse or civil partner, you can combine your allowances — effectively doubling the tax-free amount to £6,000.
Tip: Plan your property sales strategically. Selling different assets in different tax years can help maximise this exemption.
3. Transfer Property to a Spouse or Civil Partner Before Sale
Transfers between spouses or civil partners are exempt from CGT, meaning no tax is due at the time of transfer.
By shifting ownership before the sale, you can:
- Distribute the gain between two people.
- Use both CGT allowances.
- Take advantage of the lower income tax bracket of one partner (reducing CGT from 28% to 18%).
This is one of the simplest and most effective legal ways to reduce CGT on UK property sales.
4. Sell During a Low-Income Year
Because CGT rates depend on your income tax bracket, your timing can significantly impact how much tax you pay.
If you expect your income to be lower in a particular year (e.g., retirement, career change, or business slowdown), selling your property then could place you in the basic rate tax band, reducing your CGT rate from 28% to 18%.
Working with experienced tax advisors such as ABM Chartered Accountants can help you identify the most tax-efficient timing for your sale.
5. Offset Capital Losses Against Gains
If you have made a loss on the sale of another asset (such as shares, property, or crypto investments), you can offset these losses against your capital gains to reduce your CGT liability.
Losses must be reported to HMRC within four years of the end of the tax year in which they occurred.
For long-term investors, recording and declaring capital losses can be a strategic tool for future tax savings.
6. Consider Incorporating Your Property Portfolio
For landlords with multiple investment properties, transferring assets into a limited company can offer significant tax advantages, including:
- Lower corporation tax rates (currently 25%).
- The ability to deduct mortgage interest as a business expense.
- Potential to defer CGT when transferring properties, depending on structure and valuation.
However, incorporation has legal and financial complexities — professional guidance from Canary Wharf Accountants like ABM Chartered Accountants ensures the process is fully compliant and structured to your advantage.
7. Use a Trust to Manage Long-Term CGT Exposure
Transferring property into a trust can be another legitimate way to reduce CGT exposure, particularly for estate planning.
Trusts allow you to:
- Distribute ownership among beneficiaries.
- Potentially defer or reduce CGT on future disposals.
- Manage inheritance tax (IHT) exposure simultaneously.
This strategy is complex and should always be implemented under the supervision of a qualified tax expert.
8. Reinvest Gains Through the Enterprise Investment Scheme (EIS)
If you reinvest your property sale gains into qualifying EIS shares, you can defer CGT payments until you dispose of those shares.
You may also qualify for income tax relief of up to 30% on the amount invested.
This is particularly suitable for investors seeking to reinvest profits while maintaining liquidity and tax efficiency.
9. Claim Relief for Property Improvement Costs
When calculating your capital gain, you can deduct certain costs that directly relate to improving or maintaining the property, such as:
- Extensions or conversions
- Roof replacements
- New kitchens or bathrooms (if they enhance value)
- Legal fees, survey costs, and estate agent fees
These deductions can significantly reduce your taxable gain — make sure to retain all receipts and documentation.
