Audit objections versus anti evasion investigation: two different files
Same taxpayer, same year, two authorities with different instincts. They should not be answered the same way.
An audit under Section 65 is a verification of records with a statutory timeline and a communicated findings document. An anti evasion investigation proceeds under Section 67 and Section 70 with search, summons and seizure, and it is built to establish intent. The subject matter may overlap, in which case the Section 6(2)(b) bar and the objection to duplication arise, but the conduct required from the taxpayer differs materially.
How they differ in practice
The audit is documentary and cooperative. The investigation is adversarial and directed at intent.
The audit produces findings in ADT-02 that you can answer before a notice. The investigation produces statements and seizures that shape the notice before you see it.
The audit is bounded by a period and a timeline. The investigation is open ended until a notice issues.
The audit rarely results in a Section 74 notice unless the auditor records suppression. The investigation is designed to support one.
How to conduct yourself in each
In an audit: written queries, written answers, complete disclosure, and voluntary correction of genuine errors under Section 73(5).
In an investigation: the same written discipline, but with counsel involved, no payments without a protest letter, no statements signed without reading, and the blocking and attachment remedies pursued in parallel.
Where both proceed on the same subject matter, raise the Section 6(2)(b) objection and the duplication objection in writing to both authorities.
Never let the audit file and the investigation file give inconsistent answers. A single owner should see both.
What to do on Monday
Give one owner visibility of both files, and require consistency between them.
Raise the duplication and Section 6(2)(b) objections in writing to both authorities where the subject matter overlaps.
Involve counsel from day one in an investigation, and keep the audit documentary.
Correct genuine errors in the audit under Section 73(5) before the investigation reaches them.

Write to the GST practiceQuestions we are asked on this
Can an audit and an investigation run together?
They do in practice. Where the subject matter is the same, the Section 6(2)(b) objection and the duplication objection should be raised.
Should we disclose in the audit what the investigation is examining?
Answer both accurately and consistently. Inconsistency between the two files is the most damaging thing that can happen.
Does cooperating in an audit protect us in an investigation?
It establishes disclosure, which defeats suppression. That is substantial protection.
Who should handle each?
One owner with visibility of both, with counsel involved in the investigation from the first day.
Can audit findings be used in the investigation?
Yes, and they are. Which is why the audit reply must be drafted as a pleading.
