International tax lawyer

Taxation is a field that often has to deal with situations involving different tax systems and deal with any double taxation generated on the same transactions.

The tax consequences of the international mobility of people and goods are often difficult to grasp, given the boom in technology and the dematerialization of the economy. Added to this are the ever-increasing economic constraints on the budgets of states seeking both to attract talent and investment and to have their budgets financed by non-voting foreigners….

This environment creates numerous traps and obstacles that must be mastered to avoid serious setbacks. But it also brings opportunities. The tax lawyers at AlterTax support their clients, both individuals and companies, in their international development by helping them to define and implement a winning international tax strategy.

They also ensure the compliance of their operations with the French and foreign tax environment in order to secure their investments abroad and control their tax risk.

In this way, they can limit the tax exposure of French companies that have developed activities or own assets in Europe or abroad, or of foreign companies operating in France or holding assets there.

Our expertise in French tax rules, European law and bilateral tax treaties enables AlterTax Avocats’ lawyers to offer their clients solutions to avoid double taxation of the same tax base, and to optimize their overall effective tax rate.
