The United Kingdom Tax Engine
Cassandra's United Kingdom tax engine reasons over UK primary sources rather than a generic global model. Answers name the statute, the section, and the HM Revenue & Customs (HMRC) guidance relied on, so chartered tax advisers, chartered accountants, solicitors and barristers can verify the reasoning before it reaches a client.
Where a regime is in transition — currently Making Tax Digital expansion and Pillar Two multinational top-up tax — Cassandra surfaces the transition and the competing treatments instead of silently choosing one. Cross-border questions combine this engine with the applicable double tax agreement, the OECD Model Tax Convention commentary, the OECD Transfer Pricing Guidelines, and BEPS Pillar One and Pillar Two materials.
