Start with the general rule and exception
Revenue says Irish-incorporated companies are generally Irish tax-resident, subject to relevant treaty rules. Central management and control can also matter for foreign-incorporated companies. Those rules require an assessment of the particular setup. A registered-office service or formation package is not a personalised conclusion about all countries involved.
Prepare the management facts
Describe where directors live, where major decisions are made and how the business operates. Include staff, premises, contracts and other material facts your adviser requests. Separate the intended model from what is already happening. For example, an Irish address for post does not describe a board that actually makes its decisions elsewhere.
Coordinate advisers across countries
If another country is involved, ask who will assess its rules and how the advisers will share the same facts. Avoid giving different simplified descriptions to different professionals. Keep a dated setup summary and update it when the operating model changes. Your adviser can then explain potential registrations, treaty considerations and the evidence needed for the relevant position.
Review changes before relying on old advice
A director move, new office, staff hire or shift in management may change the questions. Tell the adviser before implementing a major change. Do not keep relying on formation-stage advice after the facts it assumed have changed. Retain the assessment with its scope and date so the company can identify when a fresh review is needed.
Your practical checklist
- Describe incorporation and actual management accurately
- Provide relevant locations, people and activities
- Coordinate advice for all material jurisdictions
- Avoid assuming an address fixes the tax outcome
- Review the assessment when the operating facts change
