Which tax system would be most advantageous for Mr. Young when choosing a new country to live in, assuming tax rates remain constant?

选项：

A.Residence Jurisdiction B.Source Jurisdiction C.No preference due to constant tax rates

解释：

B is the correct answer. In choosing a new country of residence, Mr. Young’s optimal tax system—either Residence Jurisdiction or Source Jurisdiction—depends on several factors, such as his non-US citizenship, EU citizenship, and the assumption of stable tax rates. In a Residence Jurisdiction, he would be taxed on his worldwide income in both the United States and his new residence. This includes income from all sources, not just the United States. Under Source Jurisdiction, taxation focuses on the income’s origin. In the United States, this means taxing only income earned within the country, regardless of Mr. Young’s citizenship. Income earned outside the United States may escape US taxation. Given constant tax rates in both countries, the choice between these systems isn’t clear-cut. Source Jurisdiction might offer tax advantages, but that depends on various intricate factors. While constant tax rates don’t tilt the balance toward either system, a detailed analysis of tax exposures is essential. Consulting international tax experts is crucial for an informed decision, although Source Jurisdiction could be more beneficial in Mr. Young’s case.
