Best order

How to organise the first pack

  1. Put HMRC decisions, notices and deadline letters first.
  2. Group tax returns, computations and schedules by tax year.
  3. Add adviser correspondence and previous submissions in date order.
  4. Separate tribunal documents, statements of case and directions if proceedings have started.

Define The HMRC Issue

The enquiry should identify the tax type, tax years, amount at stake and current stage. HMRC compliance checks, discovery assessments, penalties, VAT disputes and tribunal appeals may require different evidence.

Explain whether you are an individual, company, director, trustee, accountant or adviser, and whether any solicitor or accountant is already involved.

Evidence To Gather

A tax barrister will usually need the documents that show HMRCs position, your previous response and the records behind the disputed figures.

  • HMRC enquiry letters, information notices, closure notices, assessments, penalty notices or review decisions.
  • Tax returns, VAT returns, computations, accounts, schedules and relevant source records.
  • Bank, property, payroll, company, trust, offshore or transaction records where relevant.
  • Correspondence with HMRC, accountants, advisers and any previous representatives.
  • Chronology of HMRC contact, disclosure steps and any settlement discussions.
  • Appeal notice, tribunal correspondence, directions, bundles or hearing notices.

Scope The Barrister Work

Defined Direct Access work may include advice on merits, evidence review, draft submissions, grounds of appeal, skeleton argument preparation, settlement advice or tribunal representation.

Some matters may need an accountant, solicitor or other specialist adviser to gather records, manage correspondence, handle disclosure or provide ongoing case management.

Review Notes For Tax Procedure

Tax deadlines and procedural routes can be strict and fact-specific. Check the current HMRC notice, GOV.UK appeal guidance, HMRC manuals where relevant and tribunal rules before publication or case-specific use.

Avoid delays

What not to send first

  • Sending a narrative without the HMRC decision or notice.
  • Leaving out tax years, tax type or amount in dispute.
  • Assuming adviser emails replace the underlying records.
  • Missing review, appeal or tribunal deadlines from the first enquiry.

Source/review note: HMRC and tax tribunal procedure should be checked against current GOV.UK guidance, HMRC materials, the relevant notice and tribunal directions.

Editorial status: source and legal review required. No completed legal review is claimed.

HMRC Investigation Barrister Evidence Checklist FAQs

Can a barrister deal directly with HMRC for me?

A barrister may provide defined advice or drafting where Direct Access is suitable. Ongoing correspondence, record gathering or case management may require a solicitor, accountant or other authorised adviser.

What should I send first for a tax investigation quote?

Send the HMRC notice or decision, tax returns, computations, correspondence, deadline, tax years, tax type and any tribunal papers.

Does requesting a quote pause a tax appeal deadline?

No. A quote request does not pause HMRC, review, appeal or tribunal deadlines. Include all dates and seek specific advice quickly.
