Quick checklist
Start with these
Best order
How to organise the first pack
- Put the HMRC position, tax years, disputed amount and deadline first.
- Add written contracts, statements of work and renewal documents.
- Explain actual working practices with examples and project records.
- Include status determinations, CEST outputs if used and disagreement records.
- Add calculations, adviser correspondence, appeal papers and tribunal directions.
Show Written Terms And Reality
IR35 and off-payroll working disputes often turn on both the written documents and what happened in practice. A first enquiry should explain the contractor, agency, end-client or engager relationship, the period under review and the current HMRC or tribunal stage.
A barrister may advise on status, evidence, HMRC response, appeal strategy, drafting or suitable tribunal advocacy. Accountants, tax advisers or solicitors may also be needed for calculations, filings, correspondence or litigation conduct.
Evidence To Gather
The pack should allow a reviewer to compare contractual wording with actual working arrangements.
- Contracts, statements of work, extensions, purchase orders, agency terms and end-client terms.
- Role descriptions, project plans, deliverables, substitution evidence, supervision records and working-pattern evidence.
- Status determination statements, CEST outputs if used, disagreement correspondence and internal decision records.
- HMRC letters, information notices, closure notices, assessments, penalties, review decisions and appeal papers.
- Invoices, accounts, tax-year summaries, calculations and adviser correspondence.
- Tribunal directions, hearing dates, evidence deadlines and settlement correspondence.
Questions A Barrister May Consider
A focused request may ask whether status evidence is sufficient, whether a response or appeal needs drafting, how to organise working-practices evidence, or whether tribunal representation can be scoped.
This guide does not advise whether IR35 applies. Status and tax liability depend on the detailed facts, current law, HMRC position and evidence.
Review Notes For Tax Procedure
IR35, off-payroll working, HMRC enquiry and tribunal procedure are technical. Current HMRC guidance, tax legislation, tribunal rules and specialist tax review should be checked before detailed procedural wording is published.
Avoid delays
What not to send first
- Sending the contract without practical working evidence.
- Omitting the HMRC letter, decision or deadline.
- Leaving out tax years, sums in dispute or calculations.
- Assuming a quote request pauses an appeal, review or tribunal deadline.
Source/review note: IR35 and off-payroll working content should be reviewed against current HMRC guidance, tax legislation and First-tier Tribunal procedure before publication.
Editorial status: source and legal review required. No completed legal review is claimed.
IR35 Barrister Status Evidence Guide FAQs
Can a barrister advise on IR35 status?
A tax or employment-status barrister may advise on IR35 issues by reviewing contracts, working practices, HMRC correspondence and evidence.
Is the written contract enough?
Usually not by itself. Working practices, project records and the real relationship between the parties may also be important.
Who can request IR35 advice?
Contractors, agencies, engagers and companies may request defined advice, subject to conflicts, documents and Direct Access suitability.
