NRI Tax Filing in India: What You Need to Know

For Non-Resident Indians, tax in India is one of the most misunderstood subjects — partly because the rules turn on technical definitions, and partly because they change. The good news is that the framework is logical once you understand the two questions that drive everything: what is your residential status, and where does your income arise? This guide answers both and walks through the practical points NRIs most often ask about.

Residential status decides everything

The single most important concept in NRI taxation is residential status. It is determined by the number of days you are physically present in India during a financial year (and, in some cases, across preceding years) — not by your passport or your citizenship. You are tested afresh every year, so it is entirely possible to be a resident one year and a non-resident the next.

Indian tax law broadly recognises three categories, and the category you fall into determines how much of your income India can tax:

• Resident and Ordinarily Resident — taxed in India on worldwide income.
• Resident but Not Ordinarily Resident — a transitional status, taxed on Indian income and on certain foreign income linked to India.
• Non-Resident (NRI) — taxed in India only on income that arises, accrues, or is received in India.

There is also a special rule for certain Indian citizens with high India-sourced income who are not liable to tax elsewhere — a reminder that day-counting alone isn't always the end of the analysis. If your travel pattern is borderline, get your status assessed before you assume you're an NRI.

What income is taxable in India for an NRI

As a non-resident, you are generally taxed in India only on income with an Indian source. Common examples include:

• Salary earned for services rendered in India, or salary received in India.
• Rental income from property situated in India.
• Capital gains on the sale of Indian assets — such as property, shares, or mutual funds.
• Interest from Indian bank accounts and deposits (with important differences by account type, below).
• Business income from operations carried on in India.

Your overseas salary, foreign rental income, and gains on foreign assets are generally outside the Indian tax net while you are an NRI. The practical question is usually not "is my foreign income taxed" but "have I correctly classified my Indian income and claimed every relief."

NRE, NRO and FCNR accounts

NRIs cannot ordinarily hold a regular resident savings account, and the type of NRI account you use has direct tax consequences:

A frequent and avoidable mistake is leaving income to flow into the wrong account, or failing to redesignate resident accounts after becoming an NRI. Getting the account structure right protects both the tax position and the ability to move money home.

TDS — and how to avoid over-deduction

Tax Deducted at Source (TDS) is where NRIs most often lose cash flow. Payments to NRIs — for example, rent, or the proceeds on the sale of property — are frequently subject to TDS at higher rates than apply to residents, and the deduction happens before the money reaches you. Two tools prevent over-deduction:

1. A lower- or nil-deduction certificate — where your actual tax liability is lower than the default TDS, you can apply for a certificate authorising the payer to deduct at a reduced rate. This is especially valuable on property sales, where TDS on the full sale value can vastly exceed the tax on the actual gain.
2. Treaty relief under a DTAA — where a Double Taxation Avoidance Agreement applies, it may cap the rate or allow you to claim credit, provided you hold the right documentation.

If excess tax has already been deducted, the route to recover it is to file a return and claim a refund — which is one of the most common reasons an NRI should file even when not strictly required to.

DTAA relief and treaty benefits

A Double Taxation Avoidance Agreement (DTAA) is a treaty between India and another country that prevents the same income being taxed twice. India has DTAAs with a large number of countries, including key GCC jurisdictions. Crucially, what a treaty actually offers depends on the specific agreement and the type of income — so the right starting question is always: which treaty applies to me, and what does it say about this particular income?

By way of example, the India–UAE treaty is especially relevant to the very large NRI population in the UAE. Depending on the income and subject to the treaty's conditions, it can reduce or even eliminate Indian tax that would otherwise apply — for instance, capital gains on certain mutual fund units held by a UAE-resident NRI may not be taxable in India under the treaty. That is only an illustration: other DTAA benefits may be available under other treaties, each with its own rules, so your position must be checked against the specific agreement that applies to you.

Treaty relief is not automatic. To claim it you generally need a Tax Residency Certificate from your country of residence and to file the prescribed declaration. Getting these in place before the income arises — rather than scrambling afterwards — is what turns a treaty entitlement into actual tax saved.

When must an NRI file a tax return in India?

You generally must file an Indian income tax return if your taxable Indian income exceeds the basic exemption limit. Beyond that, there are strong practical reasons to file even when it isn't mandatory:

• To claim a refund of TDS that was deducted in excess of your actual liability.
• To carry forward capital losses for set-off against future gains.
• To create a clean record that supports repatriation and future visa or loan applications.
• To claim DTAA relief, which is given effect through the return.
