Form 3CEFB

Application for Opting for Safe Harbour in respect of Specified Domestic Transactions

What this form is

Form 3CEFB belongs to the regime of the Income-tax Act, 1961. The same ground is now covered by Form 49 of the Income-tax Rules, 2026. It is an application. Nothing follows from filing it by itself; what follows is an order, and the order is what matters. The assessee signs and files this himself.

Which provision requires it

Neither side of the department’s description names a section or a rule, so there is nothing here we can point at without guessing. The enabling provision is on the form itself.

What it became under the 2026 Rules

The description changed with the number, and the change is worth reading: the 2026 wording points at the Income-tax Act, 2025, and a great deal of what used to sit in a section of the 1961 Act now sits in a Schedule.

Where you meet it

You meet it when money, a related party or a permanent establishment sits on the other side of a border. It usually has to be in place before the transaction, not after it, and the department reads it against the treaty as well as the Act.

Published by the Income Tax Department. The link goes to their file, not a copy of it — a form is revised without notice and a stale copy is worse than none. Both are here because a notice, an order or a judgment may name either number.

What here is the department’s and what is ours. The form number, the sentence describing it, and the pairing of the old form with the form it became are all taken from the Income Tax Department’s own published forms concordance, and are reproduced as the department wrote them — including its abbreviations and its occasional typing errors. Everything else on this page is ours: the plain-English account of what the form is, the reading of which provision requires it, the grouping the form sits in, the note on where you meet it, and the selection of cases. The department has not said that this form serves that section; we have read that off the description and off its own section concordance, and we can be wrong. Before you rely on any of it, open the form.
