Section 491 of the Income-tax Act, 2025 — Sanction for Prosecution by the Principal Commissioner or Commissioner

In plain language

What Section 491 actually says

Section 491 of the Income-tax Act, 2025 is the "gatekeeper" provision for criminal prosecution under the income-tax law. It says that a person cannot be dragged into a criminal court for a tax offence unless a senior tax officer has first given written permission — called a "previous sanction". This is the 2025 Act's re-enactment of the well-known Section 279 of the Income-tax Act, 1961, and the substance is the same.

• Sub-section (1) — Sanction requirement: No prosecution can be launched for the offences listed in sections 473 to 484 (Chapter XXII offences) except with the previous sanction of the Principal Commissioner, Commissioner, Commissioner (Appeals) or Joint Commissioner (Appeals).
• Sub-section (2) — Higher-authority directions: The Principal Chief Commissioner, Chief Commissioner, Principal Director General or Director General may issue instructions or directions to the sanctioning officers on how and when to institute proceedings.
• Sub-section (3) — Protection where penalty is waived: A person cannot be prosecuted for an offence under section 478 (wilful attempt to evade tax) or section 482 (false statement in verification) for an assessment year in which the penalty under section 439 has been reduced or waived by an order under section 469.
• Compounding: Any offence under Chapter XXII may be compounded (settled by paying a fee, avoiding a criminal trial) either before or after proceedings begin, by the Principal Chief Commissioner / Chief Commissioner / Principal Director General / Director General.

Which offences need this sanction?

The sanction umbrella covers the Chapter XXII offences of the 2025 Act, including:

• Section 475 — removing/concealing property to defeat tax recovery;
• Section 476/477 — failure to pay TDS/TCS deducted or collected to the Government;
• Section 478 — wilful attempt to evade tax, penalty or interest;
• Section 479/480 — wilful failure to file returns (normal and search cases);
• Section 482 — false statement in a verification;
• Section 483 — falsification of books/documents;
• Section 484 — abetment of false returns.

Who does it apply to and why it matters

It applies to every taxpayer — individuals, HUFs, firms, companies and their directors/principal officers — who is being considered for criminal prosecution (not merely a penalty). Its purpose is protective: prosecution is a serious step carrying imprisonment, so the law inserts a senior officer's independent, reasoned approval as a filter against arbitrary or vindictive cases. A prosecution launched without a valid sanction is legally defective and can be quashed by the courts.

Key conditions and practical points

• Sanction must be genuine, not mechanical: Courts require the sanctioning authority to apply its mind to the facts. A rubber-stamp order can be struck down.
• Sanction precedes the complaint: Approval must exist before the criminal complaint is filed in court; a post-facto sanction generally does not cure the defect.
• Penalty vs prosecution are different tracks: Sub-section (3) links them only for evasion/false-verification offences — if the penalty is deleted, that specific prosecution cannot survive.
• Compounding is an exit route: A taxpayer can approach the department to compound the offence, pay compounding charges as per CBDT guidelines, and avoid a criminal record.

How it interacts with related sections

Section 491 sits at the end of the offences chapter and ties together the substantive offences (sections 473-484), the penalty machinery (section 439) and the penalty relief order (section 469). Where a taxpayer succeeds in getting a penalty waived, sub-section (3) automatically shields them from the linked prosecution — an important safeguard against being punished twice on shaky footing.
