Capital Gains Tax Services for UK Taxpayers Who Need Expert Help
CGT rates have risen, allowances have shrunk, and reporting deadlines are tighter than ever. ABM Chartered Accountants calculates your capital gains accurately, claims every relief available, reports disposals on time, and makes sure you never pay more tax than you owe.
Capital Gains Calculated and Reported Correctly
Capital gains tax applies when you sell, gift, or dispose of an asset that has increased in value. With the annual exempt amount now at just 3,000 pounds and CGT rates at 18 and 24 percent, the cost of getting it wrong is significant. ABM Chartered Accountants handles your CGT calculations, reliefs, and reporting from start to finish.
Our ICAEW and ACCA qualified accountants calculate your gains, apply the correct rates and allowances, claim Business Asset Disposal Relief where it qualifies, offset losses from current or previous years, report property disposals within the 60-day deadline, and include everything correctly on your self assessment return.
What Our Capital Gains Tax Service Covers
From calculating your gains to filing your return, here is how ABM Chartered Accountants makes sure your capital gains tax is handled accurately and every relief is claimed.

CGT Planning Advice

Pay Only What You Owe and Not a Penny More
CGT rates have increased sharply since October 2024 and the annual exempt amount has fallen from 12,300 pounds to just 3,000 pounds. These changes mean more people are paying CGT than ever before and the amounts are larger. ABM Chartered Accountants ensures every available relief is used so you keep as much of your gain as possible.
Missing the 60-day reporting deadline for property disposals triggers automatic penalties and interest. Failing to claim losses you are entitled to means paying more tax than necessary. And getting the rates wrong can result in underpayments that attract HMRC enquiries. We prevent all of this.

Frequently Asked Questions
Here are answers to the capital gains tax questions we hear most often. Contact our team for guidance.
What is capital gains tax?
Capital gains tax is a tax on the profit you make when you sell, gift, or dispose of an asset that has increased in value. You pay tax on the gain, not the total sale price. The annual exempt amount for 2026/27 is 3,000 pounds per individual.
What are the current CGT rates?
From 6 April 2026, the main CGT rates are 18 percent for basic rate taxpayers and 24 percent for higher and additional rate taxpayers. Business Asset Disposal Relief qualifying gains are taxed at 18 percent, up from 14 percent in 2025/26. The lifetime BADR limit remains at one million pounds.
Do I need to report a property sale within 60 days?
Yes. If you sell a UK residential property at a gain, you must report it to HMRC and pay any CGT due within 60 days of completion. This applies even if you also file a self assessment return. ABM Chartered Accountants handles both the 60-day report and the return.
Can I offset capital losses against my gains?
Yes. Capital losses from the same tax year are automatically offset against gains. Unused losses can be carried forward indefinitely and used against gains in future years. You must formally claim losses within four years of the end of the tax year in which they arose.
What is Business Asset Disposal Relief?
Business Asset Disposal Relief reduces the CGT rate on qualifying disposals of a business, part of a business, or shares in a trading company. From April 2026, the BADR rate is 18 percent with a lifetime limit of one million pounds. ABM Chartered Accountants checks whether your disposal qualifies.
How much does CGT advice cost?
Fees depend on the type of asset, the complexity of the disposal, and the reliefs involved. Simple share disposals cost less than complex property or business sales. We offer fixed-fee pricing agreed before we start. Contact ABM Chartered Accountants for a tailored quote.
