Form 15CB

Form 15CB is the chartered accountant’s certificate that backs the remitter’s declaration in Form 15CA Part C. Prescribed under Rule 37BB of the Income Tax Rules and read with Section 195(6) of the Income Tax Act, 1961, Form 15CB documents the CA’s professional opinion on the taxability and TDS position for any foreign remittance to a non-resident where the aggregate during the financial year exceeds ₹5 lakh and the income is chargeable to tax in India.

What is Form 15CB?

Form 15CB is the upstream professional certification that authenticates the tax treatment of a cross-border payment. The remitter’s own Form 15CA Part C is a self-declaration; Form 15CB is the independent third-party certificate from a practising chartered accountant that the remitter relies on. The two together — 15CB from the CA and 15CA Part C from the remitter, linked by the Form 15CB UDIN — form the audit trail that the bank, the Income Tax Department and the RBI rely on to release the foreign remittance.

The CA’s role is to:

• Examine the underlying invoice, agreement and supporting documentation
• Determine whether the income is chargeable to tax in India under the Income Tax Act
• Identify the correct section (commonly Section 195) and rate
• Examine the Tax Residency Certificate, Form 10F, no-PE declaration and PAN of the non-resident
• Apply the DTAA rate where eligible, and document the basis
• Certify the gross amount, tax withheld, BSR code and challan details

When Form 15CB is Required

Form 15CB is required when both conditions are met:

1. The aggregate of remittances to the same non-resident during the financial year exceeds ₹5 lakh; and
2. The remittance is chargeable to tax under the Income Tax Act, 1961

If either condition is not met, Form 15CB is not required:

For the 33 specified categories listed in Rule 37BB(3) — personal remittances, payments for imports, certain government payments — neither Form 15CA nor Form 15CB is required.

Process and Portal

Form 15CB is e-filed by the chartered accountant on the Income Tax e-filing portal (incometax.gov.in) under the CA module. The end-to-end process:

1. Engagement: The remitter engages a CA in practice and shares all supporting documentation — invoice, agreement, TRC, Form 10F, PAN, no-PE declaration
2. CA review: The CA reviews the chargeability under the Income Tax Act, applicable DTAA article, withholding rate, and computes the tax to be deducted
3. UDIN generation: The CA logs into the ICAI UDIN portal and generates a Unique Document Identification Number for the certificate
4. E-filing: The CA logs into incometax.gov.in under their CA login, navigates to e-File → Income Tax Forms → File Income Tax Forms → Form 15CB, and completes the form fields including UDIN
5. Authentication: The CA signs digitally using DSC and submits
6. Acknowledgement: The system generates an acknowledgement and the form is now available against the remitter’s PAN
7. Form 15CA Part C: The remitter then logs in, files Form 15CA Part C, and quotes the Form 15CB UDIN to link the two
8. Bank submission: Both forms are submitted to the authorised dealer bank with the SWIFT remittance instruction

The CA must retain working papers for every certificate — copies of TRC, Form 10F, agreement, invoice, computation, PAN check — for ICAI peer review and Income Tax assessment.

Common Errors and Consequences

Form 15CB sits at the intersection of professional certification and statutory withholding, so errors can attract liability on multiple sides:

• Wrong section quoted: Using Section 194J (resident professional fees) instead of Section 195 (non-resident) is a structural error and the certificate is invalid. The bank may still process the remittance, but assessment will treat it as non-deduction.
• Incorrect DTAA rate: Applying a lower DTAA rate without a valid TRC or Form 10F leads to short-deduction notices for the remitter and disallowance of the expense under Section 40(a)(i). The CA can face ICAI disciplinary proceedings for negligence.
• Form 10F not e-filed: Since CBDT Notification 03/2022 dated 16 July 2022, paper Form 10F is not recognised. The CA must verify that the non-resident has e-filed Form 10F before applying the DTAA rate.
• No UDIN or invalid UDIN: A Form 15CB without a valid UDIN is treated as not issued. The remitter cannot file Form 15CA Part C without the UDIN.
• No PAN of the deductee: If the non-resident has no PAN and the alternative documentation under Rule 37BC is not in place, Section 206AA forces the higher of the Act rate or 20%. The CA cannot certify a lower rate.
• Stale TRC: TRCs are valid only for the financial year for which issued. A TRC from a prior year cannot back the current year’s certificate.
• Disallowance: Section 40(a)(i) disallows the entire payment as a deduction in the remitter’s hands if TDS has not been deducted properly — the cost of an erroneous Form 15CB can be 25–30% of the gross remittance in additional tax.

Practical Example

A Pune manufacturing company pays USD 80,000 (₹68,00,000 at ₹85/USD) to a German engineering consultancy in June 2026 for plant design services. The German firm provides a German TRC, e-filed Form 10F, PAN and no-PE declaration.

The CA reviews the documentation and prepares Form 15CB:

The CA e-files Form 15CB, the remitter then files Form 15CA Part C quoting the UDIN, and both are submitted to the bank for SWIFT remittance of ₹61,20,000 net. The deduction is later reported in the Q1 Form 27Q filed by 31 July 2026.

If the German firm had not provided a valid TRC, the CA could not have certified the 10% DTAA rate and would have been forced to apply the 20% Act rate (or higher under Section 206AA without PAN), increasing the withholding to ₹13,60,000.

How Omnivoo Handles Form 15CB

For employers using Omnivoo to pay international vendors and contractors, Omnivoo coordinates Form 15CB with a partner chartered accountant network — collecting the TRC, validating Form 10F e-filing acknowledgement, computing the correct withholding under the applicable DTAA, generating the certificate with UDIN, and feeding it directly into the remitter’s Form 15CA Part C filing. The full cycle is then aggregated into the quarterly Form 27Q for non-resident TDS reporting. For more on TDS fundamentals, see Tax Deducted at Source (TDS).
