Not always. A company can bring advantages, but it also entails obligations and risks. We analyze whether a holding company, a holding company or investing directly as an individual is right for you.
It means determining in which country you are taxed on your worldwide income. It does not always coincide with where you live. It depends on factors such as the length of your stay, your economic interests or your family ties.
No. Although you can have several administrative residences, you can only have one tax residence. In case of conflict, the criteria of the double taxation treaties apply.
It depends on the time and type of link with your company. A prolonged relocation can generate tax obligations in the destination country. We analyze your case to avoid problems with the Tax Agency or the country where you work.
