If you are an NRI earning income from India, taxation can sometimes feel like paying for the same meal twice.

You may already be paying tax in the country where you live. At the same time, income generated in India — such as rent, interest, dividends, capital gains or certain professional income — may also have an Indian tax implication.

Does that mean you have to pay tax twice on the same income?

Not necessarily.

India has provisions designed to provide relief from double taxation, including Double Taxation Avoidance Agreements (DTAAs) with other countries. These agreements can determine which country gets the right to tax particular income and, in many cases, allow tax paid in one country to be adjusted against the tax payable in another.

However, claiming this relief is not as simple as saying, "I have already paid tax abroad." Your tax residency, source of income, the relevant DTAA and documentation all matter.

Let's break it down.

What is Double Taxation?

Double taxation occurs when the same income is taxed twice.

There are broadly two types.

1. Economic Double Taxation

This happens when the same economic income is effectively taxed more than once. A common example is when a company's profits are taxed at the corporate level and distributions to shareholders are subsequently taxed as dividend income.

2. Jurisdictional or International Double Taxation

This is more relevant to NRIs.

Suppose you live in the UK but own a property in India. You receive rental income from that property. India may have the right to tax the rental income because the property is located in India. Depending on the tax rules of the country where you are resident, the same income may also need to be reported there.

Without any mechanism for relief, the same income could effectively face taxation in both countries.

This is where DTAA for NRIs becomes important.

Your Residential Status is the Starting Point

Before looking at DTAA, determine your tax residency in India.

This is important because Indian tax rules do not simply depend on your citizenship. Citizenship and tax residency are different concepts.

For tax years beginning on or after 1 April 2026, residential status is governed by the Income-tax Act, 2025. For earlier tax years, the Income-tax Act, 1961 continues to apply. The basic residency tests have broadly remained unchanged.

Broadly, an individual can become a resident based on their period of stay in India. The commonly relevant tests include:

• Staying in India for 182 days or more during the relevant tax year; or
• Staying in India for 60 days or more during the relevant tax year and 365 days or more during the preceding four years, subject to specific exceptions and conditions.

Special rules apply to Indian citizens and persons of Indian origin visiting India, including different thresholds in certain circumstances. For example, the 60-day threshold can become 120 days for certain individuals whose Indian income exceeds ₹15 lakh. There are also provisions concerning deemed residency.

This is why an NRI who spends significant time in India should not assume that their overseas residential status automatically makes them a Non-Resident (NR) for Indian tax purposes.

What are the Different Residential Categories?

For Indian tax purposes, individuals can broadly fall into categories such as:

• Resident and Ordinarily Resident (ROR)
• Resident but Not Ordinarily Resident (RNOR)
• Non-Resident (NR)

The distinction matters because the extent to which your foreign income is taxable in India can differ significantly.

For an NRI, therefore, the first question should not be "How much tax will I pay?"

It should be:

"What is my tax residency status, and which income is taxable in India?"

Only after answering that should you move on to DTAA.

What is DTAA?

A Double Taxation Avoidance Agreement, or DTAA, is an agreement between two countries designed to address situations where income could potentially be taxed in both jurisdictions.

India has entered into DTAAs with numerous countries. However, the provisions are not identical across countries.

That is an important point.

The India-US DTAA, for example, cannot simply be assumed to work in the same way as the India-UAE, India-UK or India-Singapore DTAA.

The agreement may specify:

• Which country has the primary right to tax a particular type of income
• Maximum withholding tax rates on certain income
• How foreign tax credit can be claimed
• Rules for determining tax residency
• Special provisions for salary, interest, dividends, capital gains, pensions and other income

So, DTAA is not a blanket exemption from Indian tax. It is a mechanism for allocating taxing rights and preventing the same income from being unfairly taxed twice.

How does DTAA Help NRIs Avoid Double Taxation?

There are two broad ways in which double taxation relief can work.

1. Exemption Method

Under an exemption approach, income taxed in one country may be exempt from tax in the other country, depending on the applicable treaty provisions.

In simple terms:

Income → Taxed in Country A → Exempt from tax in Country B

The exact application depends on the relevant DTAA.

2. Foreign Tax Credit Method

The second and more commonly encountered mechanism is a Foreign Tax Credit (FTC).

Here, the income may be taxable in both countries, but the tax already paid in one country can potentially be claimed as a credit against the tax payable in the other.

For example, assume you have ₹5 lakh of income that is taxable in both jurisdictions.

If you have already paid eligible foreign tax on that income, the applicable rules may allow you to claim credit for that tax against your Indian tax liability, subject to the relevant treaty and domestic-law conditions.

This doesn't necessarily mean you receive the entire foreign tax back.

Typically, the credit is subject to limitations and cannot simply exceed the Indian tax attributable to that income.

That distinction is important when calculating your NRI income tax liability.

What About Income Earned in India?

NRIs can have several sources of Indian income, including:

• Rental income from Indian property
• Interest from certain Indian bank deposits
• Dividends from Indian investments
• Capital gains from the sale of Indian assets
• Salary for services performed in India, where applicable
• Certain professional or business income connected with India

Whether and how each income is taxed depends on Indian domestic tax law as well as the applicable DTAA.

For instance, owning a property in India and receiving rent from it does not mean the rent automatically becomes tax-free simply because you live overseas.

Similarly, an NRI investor selling an Indian asset needs to consider the applicable capital gains rules, withholding requirements and treaty provisions.

What is Foreign Tax Credit?

Foreign Tax Credit (FTC) is one of the most important mechanisms for avoiding double taxation.

Broadly, it allows an eligible taxpayer to claim credit for certain foreign taxes paid on income that is also taxable in India.

However, there are compliance requirements.

For example, the Income Tax Department states that resident taxpayers claiming foreign tax credit are required to furnish the prescribed information through Form 67, along with relevant details and proof of foreign tax paid or deducted.

The important lesson is simple:

Paying tax overseas is not, by itself, enough to automatically receive credit in India.

You need to establish the income involved, the foreign tax paid and the eligibility for credit under the applicable provisions.

Section 90 and Section 91: What is the difference?

For tax years governed by the Income-tax Act, 1961, Section 90 deals broadly with relief where India has a tax treaty with the other country.

This is commonly referred to as bilateral relief.

Where there is no applicable DTAA, Section 91 provides for unilateral relief, subject to the conditions prescribed under Indian tax law.

The practical takeaway is:

Country with DTAA → Check treaty provisions and Section 90

Country without DTAA → Check Section 91 relief

Do not assume that the absence of a DTAA automatically means you have no tax relief available.

What Should an NRI do to Reduce Double Taxation?

A practical approach is to follow these steps:

Step 1: Determine your Indian Tax Residency

Keep a record of your days spent in India. Do not rely on assumptions based solely on your overseas residence permit or citizenship.

Step 2: Identify all Indian income

List rental income, interest, dividends, capital gains, salary and other income arising in India.

Step 3: Check the DTAA with Your Country of Residence

Look specifically at the article dealing with the relevant type of income.

Step 4: Compare Domestic Law with Treaty Provisions

In many cases, taxpayers need to examine both Indian tax law and the relevant DTAA before determining the most appropriate treatment.

Step 5: Maintain Documentation

Keep tax certificates, statements, withholding records, proof of foreign tax paid and other supporting documents.

Step 6: Claim the Appropriate Tax Credit or Relief

Where FTC is applicable, ensure the prescribed reporting and filing requirements are completed. The Income Tax Department's current guidance confirms that Form 67 is used for claiming foreign tax credit under the applicable rules.

The Bottom Line

Being an NRI does not automatically mean that you will be taxed twice on the same income.

At the same time, DTAA does not mean that NRIs can simply avoid paying tax.

The objective is to prevent unfair duplication of taxation while ensuring that income is taxed according to the rules agreed between the relevant countries.

The key is to get three things right:

Your residential status + the source of your income + the applicable DTAA.

For NRIs with multiple investments, rental properties, capital gains or income across jurisdictions, taxation can become considerably more complicated. A small mistake in determining residency or claiming foreign tax credit can potentially result in excess tax, missed relief or unnecessary compliance issues.

If you have substantial investments or assets in India, a professional portfolio and tax review can help you understand how your investments, income and tax obligations fit together — and whether there are legitimate opportunities to make your financial structure more tax-efficient.
