Tax residency is one of the most consequential concepts in international structuring, and one of the most frequently misunderstood. The common assumption is that a company is tax resident in the country where it's incorporated. In many cases, that's true. In many others, it isn't — and the consequences of getting it wrong range from double taxation to criminal liability for undisclosed foreign income.

How corporate tax residency is actually determined

Most countries use one of two tests — or a combination of both. The first is the incorporation test: a company is tax resident where it was legally formed and registered. The second — and often more decisive — is the effective management and control test: a company is tax resident where its central management is exercised, regardless of where it was incorporated.

This means a company registered in Latvia but whose directors meet, make decisions, and conduct business from Italy can be deemed Italian tax resident by the Italian tax authority — regardless of what the Latvian register says. The OECD Model Tax Convention, which most bilateral treaties follow, uses the "place of effective management" as the primary tiebreaker when two countries both claim a company as resident.

The practical implication: incorporation in a low-tax jurisdiction is not sufficient. If your board meetings happen in your home country, if your decisions are made from a home office there, and if your only local presence is a registered address, the foreign registration may not protect you in a tax investigation.

Individual tax residency and its effect on your company

Individual tax residency is equally critical, because in many jurisdictions the tax residency of a controlling shareholder directly affects how the company is taxed. Most EU member states operate Controlled Foreign Corporation (CFC) rules — legislation that attributes the undistributed profits of a low-taxed foreign subsidiary back to the controlling resident individual or company. In plain terms: if you are Italian tax resident and you control a Latvian company, Italy may tax that company's profits as if they were your own income — whether or not they were ever distributed.

  • Individual residency tests vary: the UK uses a statutory residence test based on days and ties; Italy uses registration in the population register (Anagrafe), domicile, or habitual residence; Latvia uses 183 days or a declared permanent residence
  • Double Tax Treaties contain tiebreaker rules to resolve cases of dual residency — typically looking at permanent home, centre of vital interests, habitual abode, and nationality in that order
  • Changing tax residency requires genuine disconnection from the previous country — not just deregistration, but evidence that your life and economic centre have genuinely moved

What this means for your structure

A properly structured international company must address tax residency at both the corporate and individual level before anything is incorporated. The structure that works on paper in a lawyer's memo can fail entirely if the people running it continue to live and work in a high-tax jurisdiction. N3XTLV's advisory approach starts with where you and your key people actually are — then structures around that reality, not around an idealized version of it.
