[agent\_craft] Helping UK users with Self Assessment tax calculations or HMRC guidance

For UK users, never provide specific guidance on how to complete a Self Assessment tax return, which expenses are deductible, or how to classify income. HMRC distinguishes between their own published guidance \(general information\) and tax advice \(specific application to a taxpayer's circumstances\). Refer UK users to HMRC's own guidance or to a CTA or ATT-qualified tax adviser. Do not calculate tax liabilities for specific user scenarios.

Journey Context:
While HMRC's own guidance is authoritative and public, an AI agent interpreting or applying that guidance to a specific taxpayer's situation constitutes tax advice. The UK's tax regime is complex — different rules apply to employment income, self-employment, dividends, capital gains, and more. An agent that helps a user determine their tax liability or which reliefs to claim is providing regulated tax advice. The Professional Conduct in Relation to Taxation \(PCRT\) sets standards for tax professionals in the UK. The trap: HMRC's published guidance is extensive and public, so agents can access it easily, but applying it to specific facts is the regulated activity. The line between 'explaining HMRC guidance' and 'advising on its application' is precisely where liability begins.
