The four parts of Form 15CA, at a glance
| Situation | Form 15CA part | Form 15CB (CA certificate)? |
| Taxable remittance, up to ₹5,00,000 in the year | Part A | No |
| Taxable, above ₹5,00,000, with an AO order (s.195(2)/195(3)/197) | Part B | No |
| Taxable, above ₹5,00,000, no AO order | Part C | Yes — mandatory |
| Not chargeable to tax (any amount) | Part D | No |
| In the Rule 37BB specified list (33 items) | No 15CA/15CB | No |
Form 15CB is a Chartered Accountant’s certificate and is mandatory in one case only — Part C. Part D applies whatever the amount, because nothing turns on the ₹5 lakh threshold when the sum is not taxable. Failure to furnish, or furnishing inaccurate, 15CA/15CB attracts a penalty of ₹1,00,000 under Section 271-I.
If a treaty rate is claimed — TRC and Form 10F
Whenever you withhold at a lower rate under a Double Taxation Avoidance Agreement, the non-resident must give you a Tax Residency Certificate (TRC) from its home country, and — if the TRC lacks the prescribed particulars — a Form 10F, which now has to be filed electronically on the income-tax portal (a non-resident without a PAN can register on the portal to do this). A treaty rate is a flat rate: no surcharge and no cess are added on top. Where no PAN is available, Section 206AA can push the rate to 20% unless the Rule 37BC details (name, address, TIN and TRC) are on record for interest, royalty, technical fees or a transfer of a capital asset.

Frequently asked questions
When is Form 15CB (a CA certificate) actually required?
Only in Part C — when the remittance is chargeable to tax, the total to that payee exceeds ₹5,00,000 in the financial year, and you have not obtained an Assessing Officer’s order under Section 195(2), 195(3) or 197. In every other case (Part A, Part B, Part D, or a specified-list item) no 15CB is needed.
Is Form 15CA needed if the payment is not taxable in India?
Yes — you still file Form 15CA Part D for a non-taxable remittance to a non-resident, but no Form 15CB is required. Only remittances in the Rule 37BB specified list (such as import of goods for business or private travel) need no 15CA at all.
What are Forms 145 and 146?
They are the new numbers for Form 15CA and Form 15CB under the Income-tax Rules 2026, effective from 1 April 2026 (Tax Year 2026-27). The purpose and process are unchanged — Form 145 is the remitter’s declaration and Form 146 is the Chartered Accountant’s certificate. This year’s remittances still use 15CA/15CB.
Do I need a TRC and Form 10F?
Only if you are applying a lower rate under a tax treaty. The non-resident gives you a Tax Residency Certificate, and a Form 10F (filed electronically) where the TRC does not contain all the prescribed particulars. If you are simply withholding at the Act rate, these are not required.
What is the penalty for getting 15CA/15CB wrong?
Section 271-I provides a penalty of ₹1,00,000 for failure to furnish, or for furnishing inaccurate information in, Form 15CA or 15CB. The bank will also not release the remittance without a valid 15CA (and 15CB where applicable).
This wizard is a general guide for taxpayers and is not tax advice. Whether a remittance is chargeable to tax, and the correct rate, depend on the specific facts and the applicable tax treaty, and often require a Chartered Accountant’s judgement. Form and section references to the Income-tax Act, 2025 and the Income-tax Rules 2026 apply from Tax Year 2026-27 (1 April 2026); the Income-tax Act, 1961 references apply for earlier years. Verify the current position on the income-tax portal or with your advisor before remitting.
