Establish tax residence
Days present matter, but permanent home, family ties and centre of vital interests can also determine residence under domestic law and treaties.
Locate the work
Employment income may be connected to the country where duties are physically performed, subject to treaty conditions and payroll rules.
Separate social security
Social-security coordination follows its own framework. Certificates or registrations may be required even when income-tax treatment appears clear.
Protect both worker and employer
Track days and work locations, review the treaty and obtain professional advice before a long remote-work arrangement begins.
