We provide expert-led Capital Gains Tax (CGT) compliance services for individuals, businesses, trustees, and executors. Our team ensures CGT calculations and returns are prepared accurately, submitted on time, and fully compliant — reducing risk, avoiding penalties, and giving you confidence that your reporting and payment obligations are met. Whether you are dealing with a one-off asset disposal or ongoing CGT reporting, our services are tailored to your circumstances.
Capital Gains Tax (CGT) is a tax on the profit (or gain) made when you dispose of an asset that has increased in value. It is the gain that is taxed, not the total amount you receive.
Preparing CGT returns and managing payments can be complex, particularly where multiple assets, reliefs, or strict reporting deadlines apply. Having professional support ensures your calculations are accurate, your reporting is fully compliant, and your tax is paid on time — while freeing you to focus on your wider financial priorities.
When Does Capital Gains Tax Arise?
CGT can arise on a wide range of transactions, including:
• Sale of UK residential or commercial property (including buy-to-let and second homes)
• Disposal of inherited property or assets
• Sale or transfer of shares and investments
• Disposal of business assets, including goodwill
• Sale or gifting of land or property (including transfers to family members)
• Disposal of cryptoassets
• Sale of valuable personal possessions (such as artwork or antiques)
• Business restructures or cessation of trade
• Received compensation for an asset (such as insurance payouts, compensation for damage or loss)
• Acted as a trustee or personal representative and disposed of assets from a trust or estate
Different rules, reliefs, exemptions, and reporting deadlines can apply depending on the type of asset and the nature of the disposal.
Important notes
• Even if your gains are below £3,000, you may still need to report them if total disposals exceed certain thresholds or HMRC requires it.
• UK property disposals often must be reported and tax paid within 60 days of completion.
When to Report Capital Gains?
Within 60 days of selling UK residential property (using HMRC’s online CGT service)
