A tax treaty is a bilateral agreement between two countries designed to address issues related to double taxation of both passive and active income earned by their citizens. These treaties typically establish how much tax each country can levy on a taxpayer’s income, capital, estate, or wealth. Income tax treaties are also referred to as Double Tax Agreements (DTAs).
