The DTAA, or Double Taxation Avoidance Agreement is a tax treaty signed between India and another country ( or any two/multiple countries) so that taxpayers can avoid paying double taxes on their income earned from the source country as well as the residence country.
The need for DTAA arises out of the imbalance in tax collection on global income of individuals. If a person aims to do business in a foreign country, he/she may end up paying income taxes in both cases, i.e. the country where the income is earned and the country where the individual holds his/her citizenship or residence. For instance, if you are moving to a different country from India while leaving income sources such as interest from deposits in here, you will be charged interest by both India and the country of your current residence as per your consolidated global earnings. Such a scenario can have you pay twice the tax over the same income. This is where the DTAA becomes useful for taxpayers.
