international tax

International tax refers to the set of rules and agreements that govern how countries tax income earned across borders. When individuals or businesses operate in multiple countries, they may be subject to taxes in each location. To avoid double taxation—where the same income is taxed by two different countries—nations negotiate treaties and establish regulations. These frameworks help clarify who gets to tax what, ensuring fair taxation while encouraging international trade and investment. Understanding international tax is crucial for global businesses and individuals working or earning income in foreign countries.
