Purpose:
This is an original CaseWarRoom master note for Tax. It is an issue-spotting
and evidence checklist for AI agents. It is not legal advice, not a substitute for
current legislation or procedural rules, and not copied from any members-only prompt
library.

Current-law guardrails:
- Treat every limitation period, procedural deadline, statutory rate, form, regulator
  route, commencement date, and appeal/review window as something to verify against
  current official sources before relying on it.
- Separate facts proved by case materials from legal inference, missing evidence,
  strategic options, and assumptions.
- Do not invent statutory wording, case citations, monetary values, deadlines,
  regulatory guidance, or likely outcomes.
- Flag cross-border, devolved, EU/international, criminal/civil/regulatory overlap,
  and professional conduct issues where they appear.

Tax prompt pack, active_verified, reviewed 2026-06-29.

Use this as an internal issue-spotting checklist only. It is not authority. For
Tax matters, examine:
- Tax year/period: tax year/period, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Residence/status: residence/status, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Statutory basis: statutory basis, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Computation: computation, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Reliefs: reliefs, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Enquiry/assessment: enquiry/assessment, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Penalties: penalties, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Appeal route: appeal route, evidence proving or disproving it, source documents, legal thresholds, and current-law checks.
- Client objective and remedy route: desired outcome, urgency, available legal routes, settlement options, and non-court alternatives.
- Jurisdiction, forum, and governing rules: court, tribunal, regulator, governing law, territorial reach, and any mandatory procedure.
- Parties, capacity, standing, and authority: proper parties, legal personality, authority to act, standing, representatives, and conflicts.
- Limitation, deadlines, and notice requirements: trigger dates, statutory or contractual notices, appeal windows, extensions, and date evidence.

When writing outputs:
- Identify the legal test or procedural route being checked.
- Tie each issue to source documents, dates, parties, and missing evidence.
- Flag official-source checks for current law, procedure, deadlines, rates, forms,
  and commencement.
- Avoid final legal advice. Present evidence-led options, risks, and questions for
  the user or a qualified adviser to verify.
