Form 41 vs Form 10F: New DTAA Rules Under Income Tax Act 2025

India's new Income-tax Act, 2025, which came into effect from April 1, 2026, has introduced significant changes to the compliance framework for non-residents claiming relief under Double Taxation Avoidance Agreements (DTAAs). One of the most critical updates is the introduction of Form 41, which replaces the old Form 10F under the Income-tax Act, 1961. For NRIs, foreign companies, and non-resident taxpayers earning income from India, understanding these new DTAA compliance rules is essential to avoid denial of treaty benefits and higher TDS deductions.

If you're a non-resident receiving salary, interest, dividends, capital gains, royalty, or any other income from Indian sources and want to claim reduced tax rates under DTAA, you must now comply with Section 159(8) and file Form 41 electronically. This comprehensive guide explains everything you need to know about Form 41 vs Form 10F, the new documentation requirements, and how to stay compliant in FY 2026-27.

What is Form 41 Under the Income Tax Act 2025?

Form 41 has replaced Form 10F under the Income-tax Act, 2025. This shift is reflected in Section 159(8) of the Act, along with the introduction of Form 41—which replaces Form 10F under the Income-tax Act, 1961. The new form serves as a supplementary self-declaration that non-residents must furnish to support their claims for tax relief under India's Double Taxation Avoidance Agreements.

India's Income-tax Act, 2025, introduces a more structured compliance framework for non-residents claiming relief under Double Taxation Avoidance Agreements (DTAAs). While the underlying principles governing treaty relief remain unchanged, the new regime places greater emphasis on documentation and digital compliance. This modernization aligns India's tax framework with global standards and promotes technology-driven tax administration.

Structure of Form 41

Form 41 has four parts. The form requires comprehensive information from non-resident taxpayers:

• Part A: Particulars of taxpayer such as name, communication address, email etc. PAN is optional, i.e., if available to the taxpayer.
• Part B: Tax residency details and foreign tax identification number
• Part C: Nature of income received from India (salary, business income, capital gains, royalty, interest, dividends)
• Part D: Details of the applicable DTAA and the specific article under which relief is claimed

Key Difference: Form 41 vs Form 10F

There is no substantive change in purpose; Form 41 is a renumbered and digitized successor to Form 10F, aligned with the new legislative framework. However, the key differences lie in the implementation and compliance requirements:

Understanding Section 159(8) of the Income Tax Act 2025

Section 159(8) of the Income-tax Act, 2025 governs India's treaty framework, enabling the central government to enter into agreements with foreign countries or specified territories. This section is the cornerstone of DTAA implementation under the new tax law.

Rule 75 of the Income-tax Rules, 2026, provides the operational framework for implementing Section 159(8) of the Income-tax Act, 2025, and outlines the documentation and procedural requirements for claiming DTAA relief. Together, these provisions ensure that:

• Tax authorities and withholding agents can validate treaty eligibility with greater precision
• Treaty relief is properly documented and consistently applied
• India's DTAA framework aligns with global anti-abuse standards
• Digital compliance becomes the norm for international tax matters

Who Must Comply with Section 159(8)?

Non-resident individuals, companies, or other entities receiving income from India and seeking to avail of DTAA benefits. This includes:

• NRIs earning salary, rental income, or capital gains in India
• Foreign companies receiving royalty, fees for technical services (FTS), or dividends from Indian entities
• Non-resident investors earning interest from NRO fixed deposits or debentures
• Foreign portfolio investors (FPIs) claiming treaty benefits on capital gains from Indian securities
• Any non-resident taxpayer filing ITR in India and claiming DTAA relief

Tax Residency Certificate (TRC): Mandatory Requirement

A Tax Residency Certificate (TRC) remains the most critical document for claiming DTAA benefits. Tax Residency Certificate (TRC): Issued by the tax authority of the country of residence, confirming the taxpayer's residency status. Without a valid TRC, DTAA benefits cannot be claimed under any circumstances.

What TRC Must Contain

The TRC issued by foreign tax authorities should include:

• Full name of the taxpayer (individual/entity)
• Residential address in the foreign country
• Tax identification number (TIN) or equivalent
• Period of tax residency (specific financial year)
• Confirmation from the tax authority that the person is a tax resident
• Official seal and signature of the issuing authority

If the foreign TRC lacks specific details required by Indian authorities (such as TIN or nationality), non-residents must supplement it with Form 41 to provide complete information.

How to Obtain TRC from India (For Indian Residents)

Indian residents earning income abroad and seeking DTAA benefits in foreign countries can obtain TRC from Indian tax authorities by:

1. Filing Form 10FA with the jurisdictional Assessing Officer
2. Submitting proof of Indian residency (Aadhar, passport, voter ID)
3. Providing previous year's ITR acknowledgment
4. Receiving Form 10FB (the official TRC) after verification

However, for non-residents claiming benefits in India, they must obtain TRC from their home country's tax authority.

When and How to File Form 41 in FY 2026-27

The form is required to be furnished whenever treaty benefits are claimed. Where ITR is to be filed, the form is required for processing of DTAA benefit claim in the ITR. Thus, the form is required to be filed only once in a tax year.

Filing Frequency and Deadlines

While the Income-tax, Act 2025 does not prescribe any statutory deadline, Form 41 must be furnished. Typically once per financial year, for each relevant stream of income. Best practices include:

• For TDS at source: Submit Form 41 and TRC to the payer (employer, bank, company) before the income is paid to ensure lower withholding tax
• For ITR filing: File Form 41 electronically on the income tax portal before or along with your Income Tax Return
• For lower TDS certificates (Form 129): Attach copy of Form 41 as a mandatory document

Given that the new tax year begins April 1, 2026, non-residents should file Form 41 as early as possible to avoid complications.

Step-by-Step: How to File Form 41 Online

1. Visit the Income Tax e-filing portal: Log in to incometaxindia.gov.in using your credentials (PAN-based or special non-resident login)
2. Navigate to Forms section: Go to 'e-File' > 'Income Tax Forms' > Select 'Form 41'
3. Fill in details: Complete all four parts of Form 41 with accurate information about your identity, residency, income, and applicable DTAA article
4. Upload TRC: Attach a scanned copy of your valid Tax Residency Certificate issued by your home country
5. Verify and submit: Use Digital Signature Certificate (DSC), EVC, Aadhaar OTP, or Mobile OTP to verify and submit the form
6. Download acknowledgment: Save the filed Form 41 acknowledgment for your records and share with the payer if required

Consequences of Non-Compliance with Form 41 Requirements

Without Form 41 (and TRC), DTAA benefits may be denied. The payer may be required to withhold tax at full domestic rates. Failure to comply with Section 159(8) can result in denial of DTAA benefits at the withholding stage, application of standard domestic tax rates, or disallowance of treaty claims during return processing.

Impact on TDS Rates

Without Form 41 and TRC, non-residents will face maximum TDS rates on various income types:

Example: Rajesh, an NRI in the USA, earns ₹10,00,000 as interest from Indian fixed deposits. Without Form 41 and TRC, the bank deducts TDS at 30% = ₹3,00,000. With valid Form 41 and TRC under India-USA DTAA, TDS is reduced to 15% = ₹1,50,000. Rajesh saves ₹1,50,000 annually by filing Form 41.

Track your TDS deductions and verify credits using the Form 26AS / TDS Fetch Tool to ensure accurate tax reporting.

Assessment and Penalty Risks

Form 41 is specifically meant for non-residents claiming DTAA benefits. General best-judgment assessment also remains possible under section 271 for non-filing or non-compliance. Additional risks include:

• Denial of foreign tax credit in your home country due to higher Indian tax paid
• Delayed ITR processing if Form 41 is filed late or with incorrect information
• Notices from the Assessing Officer seeking explanation for claiming treaty benefits without proper documentation
• Potential addition of unreported income if DTAA benefits are disallowed

Form 41 in Context: Form 129 and Lower TDS Certificates

Non-residents can also apply for a lower TDS certificate under Form 129 before receiving payments from India. Form No. 41, Nature of payment- business income, capital gains, royalty, FTS, interest income, dividend income or other payments under the DTAA, relevant article, taxable income, tax liability, TDS rate.

What is Form 129?

Form 129 is an application filed by a non-resident or the payer to obtain a certificate from the Assessing Officer for determining the appropriate TDS rate based on DTAA provisions. This certificate ensures that:

• The payer deducts TDS at the rate specified in the certificate (usually lower than standard rates)
• The non-resident receives higher net income and avoids the hassle of claiming refunds later
• Tax compliance is maintained with proper documentation

Documents Required for Form 129

Attachments: Relevant documents such as contract for sale of goods and/or provisions for services, computation of capital gains, share purchase agreement, bank payment, details of cost of acquisition, contract note, share certificate etc. Details of income of payee/recipient of preceding four tax years. Additionally:

• Valid Tax Residency Certificate (TRC)
• Copy of Form 41 (mandatory under IT Act 2025)
• Details of taxability under DTAA
• Computation showing reduced tax liability

Form 129 applications should be filed well in advance (at least 30-45 days before payment) to receive the certificate on time.

DTAA Framework: Sections 90, 90A, and 91 in the New Act

While the Income-tax Act, 2025 has reorganized the legislative structure, the core DTAA provisions continue under Section 159. Understanding the previous framework helps appreciate the continuity:

Section 90 (Now Part of Section 159)

Two sections under the Indian Income Tax Act of 1961 offer tax relief under the DTAA. They help prevent double taxation under two different jurisdictions and provide tax relief to income taxpayers who have both Indian and foreign sources of income. Section 90 applied when India had signed a DTAA with a foreign country.

Section 90A (Now Part of Section 159)

Section 90A applied when DTAA was signed between specified associations of India and a foreign country (rather than government-to-government treaties).

Section 91 (Unilateral Relief - Continues)

Section 91 provides unilateral relief when there is no DTAA between India and the foreign country. In such cases, taxpayers can claim credit for foreign taxes paid, limited to the lower of the two tax amounts.

Important Note: Section 91 relief is only available when there is no DTAA between India and the other country. If a DTAA exists, you must use its provisions to avoid double taxation, even if you have no plans to claim its benefits.

Special Considerations for NRIs and Foreign Companies

For NRIs

Non-Resident Indians must be particularly careful about:

• Residential status determination: Individuals continue to be classified based on their physical presence in India, with thresholds such as 182 days in a tax year or 60 days combined with 365 days over the preceding four years. However, a modified 120-day rule applies to high-income individuals earning over ₹15 lakh in India, tightening residency conditions for certain NRIs.
• Multiple income sources: File separate Form 41 declarations for different income streams (salary, rental, capital gains, interest)
• Annual TRC renewal: TRCs are typically valid for one financial year only; apply for renewal before the year ends
• Claiming foreign tax credit: Use Form 67 when filing ITR in India to claim credit for taxes paid abroad

If you're an NRI with rental income from Indian property, calculate your HRA or rental tax implications using the HRA Calculator.

For Foreign Companies and FPIs

Foreign entities must ensure:

• Valid TRC from the country of incorporation/residence
• Form 41 filed for each type of income (dividends, interest, capital gains, business income)
• Compliance with Permanent Establishment (PE) rules under DTAA
• Proper documentation of beneficial ownership for treaty benefits
• Coordination with Indian payers/withholding agents for lower TDS rates

For foreign investors earning capital gains from Indian stocks or mutual funds, use the Capital Gain Calculator and Stock Profit Calculator to compute your tax liability after DTAA benefits.

Common Mistakes to Avoid When Filing Form 41

1. Filing without valid TRC: Form 41 alone is useless without a current, valid Tax Residency Certificate from your home country
2. Incorrect DTAA article reference: Each type of income is covered under specific articles of the DTAA; citing wrong articles can lead to rejection
3. Missing filing deadline: While no statutory deadline exists, filing after receiving income or after ITR deadline creates complications
4. Providing incomplete information: All four parts of Form 41 must be filled accurately; incomplete forms may be rejected
5. Not informing the payer: If claiming lower TDS, you must submit Form 41 and TRC to the payer (bank, employer, company) before payment
6. Using expired TRC: TRCs are valid for specific periods; using an expired certificate will result in denial of benefits
7. Not keeping documentation: Maintain copies of Form 41, TRC, and all supporting documents for at least 7 years for potential scrutiny

Preparing for Smooth DTAA Compliance in FY 2026-27

With the Income-tax Act, 2025 now in force, here's your action checklist:

For Non-Residents Claiming DTAA Benefits

• Obtain fresh TRC: Apply for Tax Residency Certificate from your home country tax authority for FY 2026-27 (covering period April 2026 to March 2027)
• Register on IT portal: If not already registered, create login credentials on incometaxindia.gov.in
• Prepare Form 41: Gather all information required for the four parts of Form 41
• File electronically: Submit Form 41 with TRC attachment before the first income payment or well before ITR due date
• Inform payers: Share Form 41 and TRC copies with all Indian payers (employer, bank, company paying royalty/dividends)
• Monitor TDS: Check Form 26AS regularly to verify that lower TDS rates are being applied
• File ITR on time: Submit Indian Income Tax Return by July 31, 2026 (for non-audit cases) with Form 41 reference
• Claim FTC if applicable: Use Form 67 to claim foreign tax credit for taxes paid in India when filing returns in your home country

For Indian Payers/Withholding Agents

• Request Form 41 and valid TRC from all non-resident payees before making payments
• Verify authenticity of TRC and cross-check DTAA article applicability
• Apply correct lower TDS rates only after receiving proper documentation
• Maintain records of Form 41, TRC, and payment details for reporting in TDS returns
• File TDS returns accurately with correct nature of payment codes for DTAA cases
• Issue TDS certificates (Form 16/16A) showing reduced TDS rates to non-residents

Businesses making payments to non-residents should use the Bank Statement Analyser to track and reconcile all international payments for accurate TDS compliance.

Frequently Asked Questions (FAQs)

What is Form 41 and how does it differ from the old Form 10F?

Form 41 is the new self-declaration form introduced under Section 159(8) of the Income-tax Act 2025, replacing Form 10F from the 1961 Act. While the core purpose remains unchanged—supporting DTAA claims by non-residents—Form 41 is a digitized, renumbered successor aligned with the new legislative framework. It must be filed electronically along with a Tax Residency Certificate (TRC) to claim treaty benefits. The form has four parts covering taxpayer particulars, residency details, income information, and tax treaty provisions. PAN is optional if not available to the taxpayer.

Who must file Form 41 to claim DTAA benefits in India?

Form 41 must be filed by non-resident individuals, companies, or entities receiving income from India who seek to claim benefits under Double Taxation Avoidance Agreements (DTAAs) between India and their country of residence. This applies to those claiming reduced withholding tax rates at source or seeking DTAA relief while filing Income Tax Returns. The form is required whenever treaty benefits are claimed and must be furnished at least once per tax year for each relevant income stream, as per Rule 75 of the Income-tax Rules 2026.

What is Section 159(8) of the Income Tax Act 2025?

Section 159(8) of the Income-tax Act 2025 is the legislative provision governing India's DTAA framework under the new tax law. It replaced the earlier provisions under Sections 90 and 90A of the 1961 Act. Section 159(8), read with Rule 75 of the Income-tax Rules 2026, mandates that non-residents claiming treaty relief must furnish Form 41 along with a Tax Residency Certificate (TRC). This ensures treaty relief is properly documented, consistently applied, and aligned with global anti-abuse standards. The section preserves India's DTAA framework while introducing a more structured and technology-driven compliance regime.

What documents are required along with Form 41?

To claim DTAA benefits using Form 41, non-residents must submit a valid Tax Residency Certificate (TRC) issued by the tax authority of their country of residence, confirming their residency status for the relevant financial year. Additional documentation may include proof of foreign tax identification number, details of the applicable DTAA article, nature of income (business income, capital gains, royalty, interest, dividend, etc.), and relevant contracts or payment documents. For lower TDS certificate applications (Form 129), a copy of Form 41 and TRC must be attached as per the Income-tax Rules 2026.

What happens if Form 41 is not filed or filed incorrectly?

Failure to comply with Section 159(8) by not filing Form 41 or filing it incorrectly can result in serious consequences. DTAA benefits may be denied at the withholding stage, forcing the payer to apply full domestic tax rates which can be as high as 30-31.2%. Non-residents may also face disallowance of treaty claims during ITR processing. Under Section 271 of the Income-tax Act 2025, best-judgment assessment is possible for non-filing or non-compliance. This can lead to higher tax liability, interest charges, and potential penalties. Non-residents should file Form 41 well before the ITR due date to avoid complications.

Conclusion: Navigating DTAA Compliance with Confidence

The transition from Form 10F to Form 41 represents India's commitment to modernizing its tax administration while preserving the benefits of Double Taxation Avoidance Agreements. For non-residents earning income from India, understanding and complying with Section 159(8) of the Income-tax Act 2025 is not optional—it's essential for optimizing your tax liability and avoiding penalties.

By filing Form 41 electronically along with a valid Tax Residency Certificate, you can claim reduced withholding tax rates, avoid double taxation, and ensure smooth ITR processing.
