DTAA Compliance Gets Stricter: Form 10F Now Mandatory for All Treaty Claims

 

A significant procedural shift has been introduced under the Income-tax Act, 2025 and Income-tax Rules, 2026, effective from 1st April 2026.

The change revolves around a seemingly simple document-Form 10F (now replaced by Form 41)-but its impact on international taxation compliance is far-reaching.

What was earlier a conditional requirement has now become a mandatory compliance document in every DTAA claim.

Earlier Position: Conditional Requirement under Rule 21AB

Under the erstwhile Rule 21AB of the Income-tax Rules, 1962, Form 10F was required only if certain details were missing in the Tax Residency Certificate (TRC).

These details typically included:

•  Status of the assessee (individual, company, etc.)

•  Nationality or country of incorporation

•  Tax Identification Number (TIN)

•  Period of residency

•  Address in the country of residence

If the TRC already contained all these particulars, Form 10F was not required.

This provided flexibility and reduced compliance burden in many cases.

New Regime: Mandatory Disclosure under Rule 75

With the introduction of the Income-tax Rules, 2026, Rule 21AB has been replaced, and Rule 75 now governs DTAA compliance.

The key shift is clear:

–  Prescribed particulars must now be furnished in all cases where DTAA benefit is claimed

This is to be done through:

•  Form 10F (now Form 41)

Importantly, this requirement applies irrespective of whether the TRC already contains all necessary details.

Thus, `

10F (Form 41) is no longer optional-it is compulsory.

From Conditional to Mandatory: A Major Shift

This amendment marks a fundamental shift in compliance philosophy.

Earlier, Form 10F acted as a supplementary document.

Now, it has become a primary compliance requirement, without which treaty benefits may be denied.

Impact on Foreign Remittances

The practical implications are immediate and significant.

Businesses making foreign payments must now ensure:

•  Form 10F (Form 41) is obtained in every case where DTAA benefit is claimed

•  It is available before processing remittances

This is particularly important because:

•  It is essential for filing Forms 15CA / 15CB (now Forms 145 / 146)

•  Absence of Form 10F may lead to higher withholding tax

Increased Compliance Burden

The new requirement increases documentation responsibilities for:

•  Indian payers making remittances

•  Non-resident recipients claiming treaty benefits

Even in straightforward cases where TRC is complete, Form 10F (Form 41) must still be obtained and maintained.

Emerging Practical Challenges

While the intent is to standardise compliance, several practical issues arise.

Availability of TRC at Beginning of Year

In many jurisdictions, TRC is issued only after the end of the financial year.

This raises a practical difficulty:

–  How can Form 10F (Form 41) be furnished at the start of the year when TRC itself is not yet available?

This may lead to delays or provisional compliance complications.

Multiple-Year Applicability

Another issue is whether non-residents can apply for Form 10F (Form 41) covering multiple years.

Currently, clarity on this aspect is limited, and it may lead to repetitive compliance requirements year after year.

Expanded Disclosure Requirements

The new format also requires communication details, increasing the level of disclosure expected from non-residents.

This may create additional coordination challenges, especially in cross-border transactions involving multiple jurisdictions.

Key Takeaway for Businesses

The message from the new law is clear-DTAA benefits will now be strictly documentation-driven.

Businesses must:

•  Update their compliance checklist immediately

•  Ensure Form 10F (Form 41) is obtained in all applicable cases

•  Coordinate with foreign parties well in advance

Failure to comply may result in denial of treaty benefits and higher tax withholding.

Conclusion

The transition from Rule 21AB to Rule 75 represents a decisive move towards uniform and stricter compliance in international taxation.

While the objective is to reduce ambiguity and improve data consistency, the increased compliance burden cannot be ignored.

For taxpayers and professionals, proactive planning and documentation will be the key to navigating this change smoothly.

In the evolving landscape of cross-border taxation, compliance is no longer conditional-it is compulsory.
