Introduction

For Non-Resident Indians, managing finances across two countries can feel confusing. Many NRIs earn income abroad and also receive income from India through rent, bank interest, dividends, capital gains, pension, or property sale.

Without proper tax planning, the same income may face tax in two countries. India may tax income earned or received in India, while the country where the NRI lives may also require reporting of global income.

To reduce this burden, India has signed Double Taxation Avoidance Agreements, commonly known as DTAA, with many countries. These agreements help NRIs avoid double taxation, claim lower TDS rates, and get tax credit where the treaty allows it.

As of 2026, DTAA compliance has become more document-based and form-based. Therefore, NRIs should understand the correct forms, keep proper proof, and submit documents on time.

What is DTAA?

DTAA stands for Double Taxation Avoidance Agreement. India signs this treaty with another country to decide how both countries will tax the same income.

In simple words, DTAA protects a taxpayer from paying full tax twice on the same income. It also gives clarity on which country has the right to tax a particular income.

For example, an NRI living in the USA may earn rental income from a property in India. Since the property is located in India, India can tax this rental income. At the same time, the USA may also require the NRI to report worldwide income. In such a case, DTAA may help the NRI claim credit or relief as per treaty rules.

Therefore, DTAA does not always mean no tax. It usually means fair tax.

Why DTAA is Important for NRIs

DTAA plays an important role because NRIs often deal with income in more than one country. Without treaty relief, they may face double taxation.

These agreements may help NRIs reduce TDS in India. They may also allow credit for tax paid in India or abroad, depending on the treaty and local tax rules. Moreover, DTAA gives clarity on taxation rights between India and the country of residence.

As a result, NRIs can manage their Indian income better and avoid unnecessary tax disputes.

Updated DTAA Compliance for NRIs

As of 2026, NRIs must focus on correct forms and proper documentation. Earlier, many taxpayers commonly referred to Form 10F, Form 15CA, and Form 15CB. Under the updated form structure, the income tax framework uses corresponding new form numbers.

Form 41 is linked with old Form 10F for DTAA self-declaration.

For foreign remittance information, taxpayers now refer to Form 145 in place of old Form 15CA.

Similarly, Form 146 serves the purpose of old Form 15CB for accountant certification in applicable foreign remittance cases.

Therefore, NRIs should check the applicable form on the income tax portal before claiming DTAA benefit or making foreign remittances.

Tax Residency Certificate

A Tax Residency Certificate, or TRC, is the most important document for claiming DTAA benefit.

An NRI must obtain TRC from the tax authority of the country where they live. This certificate proves that the person is a tax resident of that foreign country.

For example, an NRI living in the UK should obtain TRC from the UK tax authority. Similarly, an NRI living in the UAE should obtain it from the competent UAE authority.

Banks, companies, tenants, buyers, and other deductors may ask for TRC before applying a lower DTAA rate. Therefore, NRIs should arrange this certificate before the income becomes due.

Form 41 for DTAA Benefit

Form 41 is an important DTAA compliance form under the updated form structure. It is linked with old Form 10F.

In simple words, Form 41 works as a self-declaration for claiming treaty benefit. It provides important details such as name, address, nationality, tax identification number, residential status, and tax residency period.

This form helps the deductor verify whether the NRI is eligible for DTAA relief. Therefore, NRIs should check whether Form 41 applies before claiming lower TDS or treaty benefit.

Form 10F and Form 41 Mapping

Many taxpayers still use the term Form 10F because it was widely used earlier. However, under the updated form structure, Form 41 is the new corresponding form for old Form 10F.

So, NRIs should not rely only on the old form name. They should use the form prescribed on the income tax portal for the relevant tax year.

A simple way to understand it is this: Form 41 is the updated version linked with old Form 10F for DTAA declaration purposes.

Form 145 and Form 146 for Foreign Remittance

Foreign remittance compliance also has updated form numbers.

Taxpayers use Form 145 to provide information about payments made to a non-resident or a foreign company. Earlier, this purpose was covered through Form 15CA.

For accountant certification, Form 146 now serves the role that old Form 15CB performed in applicable cases. A Chartered Accountant certifies the nature of payment, taxability, DTAA benefit, TDS rate, and tax deduction details.

Therefore, before sending money outside India, the remitter should check whether Form 145 and Form 146 apply.

DTAA and TDS for NRIs

TDS is one of the most common areas where NRIs use DTAA.

In India, a payer may deduct tax before making payment to an NRI. This can happen in cases such as NRO bank interest, rent, dividend, property sale, capital gains, royalty, professional fees, or technical service fees.

Sometimes, the normal TDS rate can be high. However, DTAA may allow a lower rate. To claim this lower rate, the NRI must submit proper documents before payment.

If the NRI submits documents late, the deductor may already deduct tax at a higher rate. In that case, the NRI may need to file an Income Tax Return in India to claim a refund.

DTAA Rates Depend on Country and Income Type

DTAA rates are not the same for all NRIs. Each treaty has its own rules.

For example, the DTAA rate for interest may differ from the DTAA rate for dividend, royalty, or technical service fees. Similarly, the treaty rate for one country may differ from another country.

Therefore, NRIs should not rely on a general rate table. They should check the specific DTAA between India and their country of residence before claiming any lower rate.

Documents Required to Claim DTAA Benefit

An NRI usually needs the following documents to claim DTAA benefit:

Tax Residency Certificate

Form 41, where applicable

PAN card, if available or required

Passport copy

Visa or residence permit copy, if required

Foreign address proof

Self-declaration for DTAA benefit

No Permanent Establishment declaration, where applicable

Income details

Bank details for refund, if required

Among these documents, TRC and the applicable DTAA declaration form are very important. Without proper documents, the deductor may apply the normal TDS rate instead of the treaty rate.

No Permanent Establishment Declaration

A No Permanent Establishment declaration is not required in every DTAA case.

It is more relevant when an NRI earns business income, professional income, royalty, or fees for technical services from India.

Permanent Establishment means a fixed business presence in India. It may include an office, branch, project site, place of management, or dependent agent.

Through a No-PE declaration, the NRI confirms that they do not have a fixed business setup in India. This declaration helps the payer decide whether DTAA benefit can apply.

However, the NRI should give this declaration carefully. If the NRI actually has business operations in India, the tax treatment may change.

DTAA and NRO Account Interest

NRO account interest is taxable in India. Banks usually deduct TDS on this interest.

However, an NRI may request a lower DTAA rate if the relevant treaty allows it. For this, the NRI should submit TRC, Form 41 where applicable, PAN or required details, and self-declaration to the bank.

Once the bank verifies the documents, it may deduct TDS at the lower treaty rate.

DTAA and NRE Account Interest

NRE account interest is generally exempt from tax in India if the person qualifies as a non-resident under Indian tax rules.

However, the country where the NRI lives may tax global income. For example, some countries require residents to report foreign bank interest even if India does not tax it.

Therefore, NRIs should check the rules of their country of residence and report income wherever required.

DTAA and Property Sale by NRI

When an NRI sells property in India, the buyer usually deducts TDS before making payment.

DTAA may provide relief in some cases, but India generally taxes gains from property located in India. Therefore, the NRI should calculate capital gains carefully.

If the actual tax liability is lower than the TDS amount, the NRI can apply for a lower deduction certificate. Alternatively, the NRI can file an Income Tax Return and claim a refund.

DTAA and Foreign Tax Credit

Foreign Tax Credit means credit for tax paid in another country.

For example, if a taxpayer pays tax abroad on income that India also taxes, the taxpayer may claim credit as per the applicable rules.

However, NRIs should first check their residential status. In many cases, NRIs pay tax in India on Indian income and claim credit in their country of residence. The exact treatment depends on the local law of both countries and the relevant DTAA.

Residential Status and 120-Day Rule

Residential status plays a major role in NRI taxation.

The 120-day rule does not apply to every NRI. It mainly applies to certain Indian citizens or Persons of Indian Origin who visit India and have Indian income above the prescribed threshold.

Therefore, NRIs who frequently visit India should track their stay days carefully. They should also maintain passport entry-exit records and travel calendars.

If their residential status changes, their tax treatment may also change.

Equalisation Levy and Digital Business

Equalisation Levy is not a normal personal DTAA topic for most NRIs.

It mainly relates to specified digital transactions and non-resident digital businesses. Therefore, ordinary NRIs with rent, interest, dividends, pension, or property income usually do not need to focus on Equalisation Levy in a basic DTAA article.

However, NRIs who run digital businesses from outside India should take professional advice. They should check business connection, significant economic presence, permanent establishment, TDS, and DTAA provisions before taking any tax position.

Pillar Two and Large Global Business

Pillar Two rules relate to the global minimum tax framework for large multinational groups.

Ordinary NRIs with personal income from rent, interest, dividends, or property sale generally do not need to worry about Pillar Two. However, if an NRI owns or controls a large international business group, they should take expert advice before planning global tax positions.

Therefore, this point matters mainly for large global businesses, not for regular NRI personal income.

ITR Filing After Claiming DTAA

Many NRIs believe that DTAA benefit removes the need to file an Income Tax Return in India. This is not always correct.

An NRI may still need to file ITR if Indian taxable income exceeds the basic exemption limit. Filing may also become necessary when TDS has been deducted and the NRI wants a refund.

Capital gains from property, shares, or mutual funds may also require return filing. In addition, NRIs should file ITR when they want to report treaty relief properly.

The correct ITR form depends on the type of income. ITR-2 generally applies to individuals, including non-residents, who do not have business or professional income. If the NRI has business or professional income, ITR-3 may apply.

Therefore, NRIs should choose the ITR form based on their income type.

Important Compliance Checklist for NRIs

NRIs should follow this checklist before claiming DTAA benefit:

Check the DTAA between India and the country of residence.

Obtain a valid Tax Residency Certificate.

Check whether Form 41 applies for claiming DTAA benefit.

Submit PAN or required identification details to the deductor.

Give a self-declaration for DTAA benefit.

Submit No Permanent Establishment declaration, where applicable.

Give documents before TDS deduction.

Check Form 145 and Form 146 applicability for foreign remittance.

Maintain proof of tax paid in India and abroad.

Track India stay days.

File ITR in India, if required.

Claim refund if excess TDS has been deducted.

Report Indian income in the country of residence, where required.

Common Mistakes NRIs Should Avoid

NRIs should avoid these common mistakes:

Claiming DTAA benefit without TRC

Ignoring Form 41 where applicable

Submitting incomplete documents to the bank

Not giving PAN or required details to the deductor

Assuming DTAA means no tax

Ignoring ITR filing requirement

Using the wrong DTAA rate

Applying one country’s treaty rate to another country

Ignoring Form 145 and Form 146 compliance in foreign remittance cases

Not maintaining travel records

Not reporting Indian income in the country of residence

These mistakes can lead to higher TDS, refund delay, tax notice, or denial of treaty benefit.

Simple Example of DTAA Benefit

Suppose an NRI lives in Singapore and earns NRO interest from an Indian bank.

Normally, the bank may deduct TDS as per Indian tax rules. However, the India-Singapore DTAA may provide a lower tax rate on interest.

In this case, the NRI can submit TRC, Form 41 where applicable, PAN or required details, and self-declaration to the bank.

After verification, the bank may deduct TDS at the lower treaty rate. This helps the NRI avoid unnecessary high TDS. However, the NRI should still check whether the income needs reporting in Singapore.

Conclusion

DTAA helps NRIs avoid double taxation, reduce TDS, and claim tax credit where the treaty allows it. However, NRIs cannot claim DTAA benefit automatically.

As of 2026, NRIs must focus on proper documentation and correct online compliance. TRC, Form 41, PAN or required identification details, self-declaration, No-PE declaration, Form 145, Form 146, and ITR filing may become important depending on the income and remittance.

Therefore, NRIs should plan in advance, submit documents on time, and check the relevant treaty before claiming any benefit. With proper compliance, they can reduce tax burden legally and avoid unnecessary notices.
