Concept
Tax residency is a distinct status that determines which country has the right to tax your worldwide income; it does not coincide with citizenship or residence permits. Most countries consider anyone who has spent at least 183 days on their territory within 12 consecutive months to be a resident—but this is only the first and crudest criterion.
Why "183 Days" Is Not the Whole Truth
If by day count you qualify as a resident of two countries simultaneously, the dispute is resolved not by the calendar but by the tie-breaker in Article 4 of the OECD Model Tax Convention: where you have a permanent home, then centre of vital interests (family, business, economic ties), then where you habitually reside, and only lastly—citizenship. Therefore, "leaving for 184 days" by itself does not sever ties with a country if your family, home, and affairs remain there.
⚙️ 183 days is merely a threshold. Tax attachment is determined by the facts of life: where your home, family, and centre of interests are located. A stamp in your passport alone does not break that connection.
The "Nowhere Resident" Myth
The idea of "spending less than 183 days everywhere and being a tax resident nowhere" is the most dangerous notion in flag theory. "Resident nowhere" does not equal "owing nothing to anyone": the US taxes by citizenship, other countries tax by source of income or under "deferred" residency rules. And without resident status, you fall outside the network of tax treaties and lose protection from double taxation.
Moreover, banks report under CRS precisely by tax residency—"nowhere" means either refusal of service or reporting by citizenship. A clean structure is not the absence of residency, but a deliberately chosen "good" residency.
💡 The goal of Flag 2 is to replace expensive tax residency with a favourable and sustainable one: UAE, non-dom regimes, flat tax, territorial systems.
