It means Avoidance of double taxation of same Income. If a person earned income in 2 or more countries and these countries has signed DTAA then this income will taxable as per this agreement.
If these countries has not signed DTAA then this income will be taxable in all countries.
For Example: A resident of India, also have income in USA. As India and USA has signed the DTAA then income from USA will be taxable as per provisions given in the DTAA i.e. this income will be taxable only in one country either in USA or India.
If there was no DTAA between USA and India, then first this income will be taxable in USA and after that it will be taxable in India.
