[agent\_craft] Generating code that structures tax transactions without DOTAS awareness

Never generate code that creates artificial tax structures, circular financial flows, or aggressive tax positions. If the agent encounters a request to implement tax-optimization logic involving multi-entity structures, offshore arrangements, or novel interpretations of tax law, flag it for mandatory human review. Implement a pattern-matching guard for known DOTAS hallmarks \(e.g., confidentiality clauses, premium fees contingent on tax outcome\).

Journey Context:
HMRC's Disclosure of Tax Avoidance Schemes \(DOTAS\) regime requires 'promoters' of certain tax schemes to notify HMRC. The definition of 'promoter' is broad and can include software providers whose code implements or facilitates reportable schemes. The Finance Act 2004, Part 7, establishes the DOTAS framework, and HMRC maintains a list of 'hallmarks' that trigger reporting. The critical mistake: developers think they're just 'implementing business logic' when they're actually creating a tax avoidance arrangement. The penalties for non-disclosure are severe — up to £1 million. The tradeoff is that legitimate tax planning and illegal tax avoidance exist on a spectrum, and the line is often unclear. The safe approach is to flag anything with DOTAS hallmarks for expert human review rather than attempting to make the determination algorithmically.
