Dubai's value lies not in "0% tax," but in whether you can assemble people, entities, and fund flows into a system that can be audited and explained. After CARF, the question is no longer "Am I in Dubai," but whether you can prove the consistency of your tax-resident status, the pricing basis for related-party transactions, and your business logic. A company with no real business, chaotic related-party transactions, weak proof of residency, and a single-passport profile—four high-frequency pitfall scenarios are dissected one by one to build a defense system for tax residency and cash flow in the CARF era.
