Double Taxation

When the same income is taxed by two different countries — resolved through tax treaties or foreign tax credits.

Full Definition
Double taxation arises when two jurisdictions both claim to tax the same income. It is avoided through: bilateral tax treaties (DTAs) that allocate taxing rights; unilateral foreign tax credits; or exemption methods. The OECD Model Tax Convention is the template for most of the 3,000+ treaties in force globally.

Tax treaties are the foundation of cross-border tax planning. Without a treaty, the same income can be taxed by two countries simultaneously.
