How to organise the first pack
- Put HMRC decisions, notices and deadline letters first.
- Group purchase, disposal, transfer and valuation papers by asset.
- Add computations, return extracts, relief claims and adviser correspondence.
- Separate review, appeal, tribunal and settlement papers if the dispute has progressed.
Define The CGT Issue
The enquiry should identify the asset, tax year, disposal date, reported gain, HMRC figure and the relief or valuation point in dispute. Capital gains tax issues may involve property, shares, business assets, trusts, estates or non-resident disposals.
GOV.UK tax appeal guidance says the decision letter should explain how to challenge an HMRC decision and that many tax appeals use a short deadline. The current decision letter should be checked before publication or case-specific use.
Evidence To Gather
A tax barrister will usually need the documents showing the transaction, the calculation, HMRCs position and the evidence behind any relief or valuation argument.
- HMRC enquiry letters, assessments, penalties, closure notices, review decisions or tribunal correspondence.
- Tax returns, CGT computations, SA108 pages, property disposal returns and supporting schedules.
- Purchase, sale, transfer, completion, probate, trust, share or cryptoasset records where relevant.
- Valuation evidence, base cost evidence, enhancement expenditure and professional fee records.
- Relief claim evidence, residence history, business asset documents and adviser correspondence.
- Chronology of the disposal, reporting steps, HMRC contact and any settlement discussions.
Scope The Barrister Work
Defined Direct Access work may include advice on merits, relief conditions, evidence review, draft submissions, grounds of appeal, skeleton argument preparation, settlement advice or tax tribunal representation.
Accountants, valuers, solicitors or other advisers may be needed to prepare calculations, valuations, records, disclosure or ongoing correspondence.
Review Notes For Tax Procedure
CGT rules and HMRC appeal routes are technical. Reviewers should check current HMRC guidance, the tax decision letter, tribunal rules and specialist tax sources before adding procedural detail or tax-rate statements.
Avoid delays
What not to send first
- Sending a tax narrative without the HMRC notice or computation.
- Leaving out disposal dates, tax years or the disputed figure.
- Relying on adviser emails without the underlying asset and valuation records.
- Missing review, appeal, payment or tribunal deadlines from the first enquiry.
Source/review note: checked against GOV.UK tax appeals guidance and HMRC CGT/property disposal guidance on 11 August 2026; technical CGT points require tax-specialist review before publication.
Editorial status: source and legal review required. No completed legal review is claimed.
