Form 15CA and 15CB: The Remittance Paperwork, Now Forms 145 and 146

Form 15CA is the remitter's online declaration that tax has been considered on a payment leaving India. Form 15CB is the chartered accountant's certificate backing that declaration for taxable remittances above the threshold. From 1 April 2026, under the Income-tax Act, 2025, Form 15CA is renumbered Form 145 and Form 15CB is renumbered Form 146. The substance carries over; some fields are new. No bank will wire your property sale proceeds abroad without them.

What each form does

Form 15CA (now Form 145) is filed by the person sending the money: you, the NRI account holder, or any remitter paying a non-resident. It declares the nature of the remittance, the amount, and the tax position. It is filed on the income tax e-filing portal before the bank executes the transfer.

Form 15CB (now Form 146) is a certificate from a practising chartered accountant. The CA examines the source of funds, the taxability of the remittance, the rate applied, the DTAA position if claimed, and certifies the details. It is the CA's signature on the line, with a UDIN. The bank relies on it; so does the tax department.

The renumbering is confirmed by the Income Tax Department: the portal lists Form 145 with the note "earlier Form 15CA," and the department's FAQs say the same. Banks and CAs will use the old names in conversation for years. The portal will not.

The four parts of Form 145 (old 15CA)

Part When it applies
Part A Taxable remittance, total in the financial year up to Rs 5 lakh
Part B Taxable remittance above Rs 5 lakh, covered by a lower/nil TDS order or certificate
Part C Taxable remittance above Rs 5 lakh, backed by a CA certificate in Form 146 (old 15CB)
Part D Remittance not chargeable to tax in India

Property sale proceeds and NRO balance transfers almost always travel under Part C with a Form 146, or Part D where the remittance is not chargeable. The CA decides which, on paper, with reasons. Confirm the current thresholds on the portal before filing; the structure above carried over from Rule 37BB of the old regime.

Who does not need the forms

The rules carve out a specified list of remittance purposes, 33 categories under the old Rule 37BB, where no Form 15CA/15CB is needed at all. The list covers items like imports, certain travel and education remittances, and other current-account payments by residents. Two practical points for NRIs:

Do not rely on a blog list of exemptions, including this one. Check the current rule on the portal or have the CA cite it in the certificate.

Step-by-step e-filing

  1. The remitter logs in to the e-filing portal and assigns Form 146 (old 15CB) to a CA under "My CA," authorising that CA for the form and the year.
  2. You give the CA the full file: source-of-funds proof (sale deed, TDS certificates, bank statements), PAN, passport, the remittance amount, the destination account, and the purpose.
  3. The CA files Form 146 online with a digital signature and generates the UDIN.
  4. You (or the CA on your behalf) file Form 145 in the correct part, pulling in the Form 146 acknowledgment number.
  5. Download both acknowledgments. Submit them to the bank with Form A2 (the FEMA outward remittance declaration) and the bank's own repatriation request form.
  6. The bank's trade or NRI desk verifies, then executes the wire.

Each remittance needs its own filing. Splitting a large transfer into tranches means a fresh Form 145, and often a fresh 146, per tranche.

What changed under the Income-tax Act, 2025

If a bank officer or an older guide insists the forms are "15CA/15CB," they mean Forms 145/146. Filing under the old form numbers is not possible on the portal for transactions on or after 1 April 2026.

Where this goes wrong

FAQ

Are Form 15CA and 15CB still called that in 2026? The forms are renumbered: Form 145 replaces 15CA and Form 146 replaces 15CB from 1 April 2026 under the Income-tax Act, 2025. Same job, new numbers, some new fields.

Who files which form? The remitter files Form 145. A practising CA files Form 146. For an NRI moving property sale proceeds, the CA prepares both in most cases and the NRI authorises the CA on the portal.

Is Form 146 (15CB) always required? No. It is required for taxable remittances above Rs 5 lakh in the year that are not covered by a lower/nil TDS order. Exempt-list remittances and NRE transfers need neither form. Confirm against the current rule.

Do I need the forms to move money from NRO to NRE? Yes. Banks treat NRO-to-NRE transfers like outward remittances under the USD 1 million scheme and ask for Forms 145 and 146.

Can the bank remit without the forms? For NRO property proceeds, no. The authorised dealer bank is required to collect the declarations before remitting.

How long does filing take? With documents ready, a CA can file Form 146 and Form 145 in two to four working days. The bank's processing adds two to ten working days.

What happens if the form has an error after the wire went out? Form 145 can be withdrawn within a limited window. Past that, corrections get messy and may need the assessing officer. Get it right before the bank executes.
