In one line

Section 65 lets the tax authorities conduct an AUDIT of a registered person’s records at their premises or the office, with 15 days’ notice, to be completed within three months (extendable), findings communicated in ADT-02.

What this means in practice

The parts that actually decide cases — the things a practitioner checks first.

1

Fifteen working days’ notice in ADT-01; audit to be completed within three months of commencement, extendable by six months by the Commissioner with reasons recorded.

2

‘Commencement’ means the date the records asked for are made available or the audit actually starts, whichever is later – the clock does not start with the notice.

3

Findings come in ADT-02 within thirty days of completion; any tax discovered is then demanded under section 73 or 74A, not under section 65 itself.

4

The department cannot audit a period already covered by a completed audit without fresh material – raise it early if a second notice covers the same year.

Questions people actually ask

Real questions we get on this provision, answered straight.

The audit has been running for eight months. Is that allowed?+

Three months from commencement, extendable by six by the Commissioner with reasons recorded in writing. Ask for the extension order; if none exists, the audit is beyond time and anything built on it is open to challenge.

How this provision is built

(6) On conclusion of audit, the proper officer shall, within thirty days, inform the registered person, whose records are audited, about the findings, his rights and obligations and the reasons for such findings.
