Tax Treaty (Double Taxation Agreement)

A bilateral agreement setting out which country taxes which types of income — and at what rates.

Full Definition
Tax treaties (DTAs) eliminate double taxation by allocating taxing rights. A typical DTA covers: employment income (taxed where work is performed), business profits (taxed where PE exists), dividends/interest/royalties (withholding caps 5–15%), capital gains, and pensions. Treaties also include exchange-of-information provisions. Not all countries have treaties — expats in treaty-less situations must rely on domestic foreign tax credits.
