Section 491 Income Tax Act 2025: Is Prior Sanction Required Before Tax Prosecution?
Can the Income Tax Department launch criminal prosecution without prior approval? Section 491 regulates sanction for prosecution, supervisory directions, protection following specified penalty waivers and compounding of offences under the Income-tax Act, 2025.
What does Section 491 of the Income-tax Act, 2025 provide?
The statutory heading is "Prosecution to be at instance of Principal Chief Commissioner or Chief Commissioner or Principal Commissioner or Commissioner." The section contains six subsections dealing with authorisation of prosecution, administrative directions, an exclusion linked to certain penalty relief, compounding, evidentiary admissibility and Board instructions.
The Income-tax Act, 2025 came into effect on 1 April 2026. Section 491 broadly corresponds to Section 279 of the Income-tax Act, 1961. The application of the former legislation to earlier periods must be examined under the applicable transition and saving provisions.
Section 491(1): Who must sanction prosecution?
No person may be proceeded against for an offence under Sections 473, 474, 475, 476, 477, 478, 479, 480, 481, 482, 483 or 484 without the previous sanction of one of the following authorities:
- Principal Commissioner;
- Commissioner;
- Commissioner (Appeals); or
- Joint Commissioner (Appeals).
Previous sanction means approval required before the prosecution is instituted. It is distinct from a tax assessment, penalty order or internal recommendation. Whether sanction is valid in a particular case depends on the competent authority, applicable procedure and the facts presented for approval.
Section 491(2): Directions for instituting proceedings
The Principal Chief Commissioner, Chief Commissioner, Principal Director General or Director General may issue instructions or directions to the authorities identified in subsection (1) concerning the institution of proceedings. This is a supervisory power; it does not eliminate the express requirement of previous sanction.
Section 491(3): When does penalty relief bar prosecution?
A person cannot be proceeded against for an offence under Section 478 or Section 482 in relation to an assessment for a tax year where the penalty imposed or imposable under Section 439 has been reduced or waived by an order under Section 469.
This protection is tied to the specific sections and statutory conditions stated above. It does not automatically extend to every offence, every penalty concession or every case where a tax demand is reduced.
Section 491(4): Can income-tax offences be compounded?
Yes. Any offence under the relevant Chapter may be compounded before or after institution of proceedings by the Principal Chief Commissioner, Chief Commissioner, Principal Director General or Director General. Compounding generally means resolving an offence through the legally authorised process, subject to applicable guidelines, conditions and payment requirements.
Compounding is not automatic merely because an application is submitted. Eligibility, procedure and terms must be checked against the applicable statutory powers and current administrative instructions.
Section 491(5): Are earlier statements and documents admissible?
Where proceedings have been taken under subsection (1), a statement made, or an account or other document produced, before an income-tax authority specified in Section 236(a) to (k) is not inadmissible merely because it was furnished in the belief that:
- a penalty might be reduced or waived under Section 469; or
- the offence might be compounded.
This provision addresses those two stated grounds of inadmissibility. It does not dispense with other legal requirements governing relevance, authenticity, admissibility or proof.
Section 491(6): Board directions on compounding
The Board's power to issue orders, instructions or directions includes instructions to other income-tax authorities for proper compounding of offences under Section 491. Such instructions may require previous approval of the Board. Taxpayers and practitioners should check the directions applicable when a compounding request is considered.
Relevant statutory terms and connected provisions
Practical checklist before initiating or contesting prosecution
- Identify the exact offence and whether it falls within Sections 473 to 484.
- Verify that previous sanction was issued by an authority specified in Section 491(1).
- Examine the sanction order and underlying allegations for procedural compliance.
- For Sections 478 and 482, determine whether Section 439 penalty was reduced or waived by an order under Section 469.
- Consider whether compounding is available under current applicable instructions.
- Distinguish prosecution sanction from the separate classification of offences under Section 492.
Practical illustrations
Example 1: Prosecution for a false verification
A taxpayer is accused under Section 482. Before prosecution, the prescribed previous sanction is required. If the statutory conditions in Section 491(3) are fulfilled through a qualifying Section 469 order relating to the Section 439 penalty, the express bar to proceeding must also be considered.
Example 2: Compounding after proceedings begin
Prosecution is already instituted for a covered tax offence. Section 491(4) permits compounding even after institution, but the taxpayer must satisfy applicable conditions and obtain a decision from the competent authority.
Section 491 compared with Section 279 of the Income-tax Act, 1961
Section 491 substantially carries forward the statutory framework of Section 279 of the 1961 Act, including prior sanction, compounding and connected safeguards. Earlier judicial interpretations may assist where the statutory language and legal context correspond, but their application requires attention to the facts and governing law.
Frequently asked questions
Is prior sanction compulsory for prosecution under Section 478?
Yes. Section 491(1) expressly includes Section 478 among the offences for which previous sanction of a specified authority is required.
Can an income-tax offence be compounded after prosecution starts?
Yes. Section 491(4) expressly allows compounding before or after institution of proceedings, subject to competent-authority approval and applicable conditions.
Does a waiver of any income-tax penalty prevent prosecution?
No. Section 491(3) sets out a specific bar concerning Sections 478 and 482 where the Section 439 penalty for the relevant tax year has been reduced or waived by an order under Section 469.
Does Section 491 itself impose imprisonment or a fine?
No. Section 491 concerns prosecution procedure, sanction, compounding and related matters. Punishment is prescribed by the substantive offence provisions.
