Audit reports and accountants' reports Became Form 66

Form 29B

Report under section 115JB of the Income-tax Act, 1961 for computing the book profits of the company

What this form is

Form 29B belongs to the regime of the Income-tax Act, 1961. The same ground is now covered by Form 66 of the Income-tax Rules, 2026. It is a report — somebody with a professional obligation putting a set of facts on record for the department to act on. The assessee signs and files this himself.

Which provision requires it

Left, the provision as the department’s description names it. Right, where the same ground is covered now — taken from the department’s own section and rule concordances, not worked out by us.
What the description namesWhere it sits now
section 115JB of the 1961 Actsection 2, section 206

Rules of the 2026 Rules that work the same section. rule 118 (Relief in tax payable under section 206(1) due to operation of). This is our own matching — we have paired the section the form names with the rules whose headings name that same section. The department has not said that any of these rules prescribes this form.

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 in the run-up to the filing date, when a claim in the return needs an accountant’s report behind it. The report goes in separately from the return, and it usually has to be in before the return is.

On the same provision

Decisions in this library that turn on the same provision of the 1961 Act that this form names. They are about the provision, not about the form; a case is listed here because it argues the section, and none of them is authority on how the form itself is to be filled in.

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.
