double taxation treaties are agreements between two countries. they determine which country gets to tax what income. and at what rate.
india has signed such agreements with 94 countries. for an indian resident with income from abroad, or a foreign resident with income from india, these treaties can save significant money.
without a treaty, the same income could be taxed twice. once in the country where it is earned. once in the country where the person lives. the treaty prevents that.
the two methods of relief
treaties use two approaches to avoid double taxation.
the exemption method. income is taxed only in one country. the other country exempts it entirely. the country where the income arises typically has the first right to tax. the country of residence then exempts it.
the credit method. income is taxed in both countries. but the country of residence allows a credit for tax paid in the other country. the credit is limited to the lower of the foreign tax paid or the indian tax payable on the same income.
india follows the credit method. a resident can claim relief for taxes paid abroad. this is done using form 67, filed before the itr due date.
what treaties typically cover
treaties set rules for different types of income.
dividends face a standard domestic withholding rate of up to 20% for non-residents. treaties often bring this down to 10% or 15%. under the india-singapore treaty, the rate is 10% if the recipient is a company holding at least 25% of the shares. for other cases, it is 15%.
interest rates follow a similar pattern. the domestic rate can go up to 20%. treaties usually cap it at 10% to 15%. for banks and financial institutions, the rate can drop to 10%.
royalties and fees for technical services have a domestic rate of up to 20%. treaty rates are often 10% to 15%.
capital gains rules vary by treaty. some give the country of residence the right to tax. others give the country where the company is resident the right. the india-france treaty was amended in february 2026 to give full taxing rights on share capital gains to the country where the company is resident.
the permanent establishment rule
a foreign company is taxable in india only if it has a permanent establishment here. a permanent establishment is a fixed place of business. office, branch, factory, workshop. a building site or construction project lasting more than six months can also qualify.
the us and uk treaties have detailed definitions of permanent establishment. many foreign companies accidentally create a taxable presence in india by exceeding these limits. understanding the rule helps avoid unexpected tax liability.
the principal purpose test
treaty benefits are not automatic. the principal purpose test denies benefits if one of the main reasons for using a particular structure was to get a tax advantage. the test applies prospectively from october 1, 2019.
grandfathering. investments made before april 1, 2017 are protected. the principal purpose test does not apply to them.
substance requirements. a tax residency certificate alone is not enough. the claimant must prove genuine economic substance in the treaty country. a recent supreme court ruling in the tiger global case clarified that residency must be accompanied by commercial substance and effective management.
documentation requirements
to claim treaty benefits, specific documents are required.
tax residency certificate (trc). this is mandatory. it proves the person is a resident of the treaty country. without it, the standard domestic rates apply.
form 41 (form 10f). a self-declaration form filed online through the income tax portal. it must be filed annually.
beneficial ownership tests. the recipient must be the true owner of the income. not just an agent or nominee passing it on. the entity must have genuine business presence, employees, and management.
why it matters for investors
a treaty can reduce tax liability significantly. an nri earning rent in india might pay 30% tds without a treaty. with a treaty, the rate could be lower. a foreign investor receiving dividends might pay 10% instead of 20%.
but benefits do not apply automatically. the correct documents must be filed. the structure must have genuine substance. the principal purpose test must be satisfied.
