Capital Gains Tax Calculations and Reporting
Capital Gains Tax can arise when you sell or dispose of an asset that has increased in value, such as shares, business assets or a residential property that is not your main home. Sterling Crest Accountants calculates gains and losses, applies reliefs where the facts support them, and reports the disposal through Self Assessment or the separate UK property return where that is required.
Sterling Crest Accountants provides this service to clients throughout the United Kingdom. Consultations are arranged in advance by telephone or online meeting. Our registered office is in Leeds, West Yorkshire.
About Capital Gains Tax
Each disposal needs proceeds, base cost, incidental costs of acquisition and disposal, and enhancement expenditure evidence. We build a computation schedule you can keep for HMRC questions.
Residential property disposals may require reporting within 60 days of completion for UK residents in scope of the rules. We prepare the return when engaged and you provide completion statements promptly.
Reliefs such as private residence relief, business asset disposal relief and losses brought forward depend on detailed facts. We apply the rules HMRC publishes but do not promise relief outcomes without evidence.
Gains may feed the main Self Assessment return or a separate reporting route depending on asset type and timing. We coordinate with inheritance tax work only where separately engaged.

Key deadlines
Many gains are reported on the Self Assessment return, due by 31 January after the end of the tax year. Where a UK resident sells UK residential property and Capital Gains Tax is due, a separate return and payment are normally required within 60 days of completion.
Confirm official dates and rules on GOV.UK. Rules and thresholds can change.
