Under section 279(1) of the Income-tax Act, 1961, prosecution for the listed tax offences required previous sanction from one of these authorities: the Principal Commissioner or Commissioner, the Joint Commissioner (Appeals), the Commissioner (Appeals), or the prescribed appropriate authority. A Principal Chief Commissioner, Chief Commissioner, Principal Director General or Director General could issue directions about instituting proceedings, but that direction-making power was not the same as the statutory sanction itself.
This answer concerns the 1961 Act. The Income-tax Act, 2025 changed the numbering: its section 279 addresses income escaping assessment, while published section-correspondence material identifies old section 279’s successor as section 491. The 1961 Act was repealed with effect from 1 April 2026, subject to transition rules for assessment years already begun under it. For a live matter, identify the governing Act and verify the current official text before relying on a section number.

Who were the sanctioning authorities under section 279(1)?
Section 279(1) of the Income-tax Act, 1961 prohibited proceedings for specified Chapter XXII offences unless the prosecution had received previous sanction from a listed authority. The statutory list was broader than a single senior commissioner:
- the Principal Commissioner or Commissioner;
- the Joint Commissioner (Appeals);
- the Commissioner (Appeals); or
- the appropriate authority, where the Act assigned that role by reference to section 269UA(c).
The sanction had to exist before the prosecution was proceeded with. The Supreme Court, in its judgment dated 7 February 2025, described prior sanction as a prerequisite for launching the prosecutions covered by subsection (1). That requirement is why the officer who investigates a suspected default, prepares a prosecution proposal or presents a complaint is not automatically the officer legally empowered to grant sanction.
#1 Best Overall
The official heading of the 1961 provision was “Prosecution to be at instance of Principal Chief Commissioner or Chief Commissioner or Principal Commissioner or Commissioner.” The heading should not be read as replacing the detailed list in subsection (1). In particular, it does not make the Principal Chief Commissioner or Chief Commissioner the only possible sanctioning authority.
Which offences did the 1961 Act’s section 279(1) cover?
The Supreme Court reproduced subsection (1) as applying to prosecutions under sections 275A, 275B, 276, 276A, 276B, 276BB, 276C, 276CC, 276D, 277, 277A and 278 of the 1961 Act. Those provisions covered different forms of non-compliance, including failures connected with tax recovery, payment, returns, information and verification, as well as specified conduct involving concealment or false statements.
The sanction rule was therefore tied to the offences named in that provision, not to every dispute under the Income-tax Act. A tax demand, penalty order or assessment adjustment did not by itself establish that a prosecution could be filed. The proposed charge had to fall within a covered offence and satisfy the procedural requirements applicable to that offence.

Section 279(1A) created a specific limitation for certain prosecutions under sections 276C and 277. Where the relevant penalty had been reduced or waived under section 273A for the assessment year concerned, the Act barred proceedings in the circumstances described by subsection (1A). This is a targeted statutory qualification, not a general rule that every reduced penalty prevents prosecution.

Sanction, directions, complaint filing and compounding are different powers
Confusion often arises because several officials may appear in the same prosecution file. The 1961 Act separated their legal functions.
| Function | Who could exercise it under the 1961 Act | What it did | Timing or limitation |
|---|---|---|---|
| Previous sanction under section 279(1) | Principal Commissioner or Commissioner; Joint Commissioner (Appeals); Commissioner (Appeals); or the applicable appropriate authority | Provided the statutory approval needed before a covered prosecution could proceed | Had to precede institution or continuation of the covered prosecution as required by the provision |
| Directions under the proviso to subsection (1) | Principal Chief Commissioner, Chief Commissioner, Principal Director General or Director General | Issued instructions or directions to the authorities dealing with institution of proceedings | A direction did not automatically become the individual sanction required by subsection (1) |
| Compounding under subsection (2) | Principal Chief Commissioner, Chief Commissioner, Principal Director General or Director General | Considered whether the offence could be compounded | Could occur before or after institution; it was a separate discretionary decision |
The Supreme Court has distinguished compounding from sanction. Compounding is an enabling discretion, not an entitlement that an assessee can demand before prosecution begins. A person cannot treat a compounding application as a substitute for the previous sanction required to institute a prosecution.
Likewise, an instruction from a senior official about pursuing a case does not, without more, answer whether the officer named in the sanction order was authorized under subsection (1). The order, the statutory provision invoked, any delegation and the administrative chain must be examined together.

An Assessing Officer may investigate facts, record reasons, collect evidence, communicate with the prosecution wing or present a complaint through the procedure prescribed by the department. Those operational steps do not, by themselves, make the Assessing Officer a sanctioning authority under section 279(1).
Whether a particular officer could sign, forward or institute a complaint depends on the authority conferred by the applicable statute, rules, delegation and administrative instructions. It is therefore unsafe to say either that an Assessing Officer can never be involved or that the Assessing Officer’s signature alone proves valid institution. The key questions are:
- Which offence and statutory section were alleged?
- Which version of the Income-tax Act governed the conduct and assessment year?
- Who signed the previous-sanction order?
- Did that person fall within the statutory list or hold a valid delegation?
- Was the sanction granted before the prosecution was instituted, and does the order show application of mind to the proposed case?
A complaint filed by one officer can therefore be procedurally distinct from sanction granted by another. The filing officer’s identity does not, on its own, answer the validity of the sanction.
Does section 279 still apply after the Income-tax Act, 2025?
Not as the current section number for new matters. The Income-tax Department’s page for section 279 of the Income-tax Act, 2025 labels that provision “Income escaping assessment.” That is a different subject from the 1961 Act’s prosecution provision.

A reproduced version of section 491 describes a previous-sanction requirement involving the Principal Commissioner, Commissioner, Commissioner (Appeals) or Joint Commissioner (Appeals) for its enumerated offences. Because the correspondence and reproduced text are secondary material, they should be checked against the official consolidated 2025 Act and its commencement and transition provisions before being used to decide a case.

Why the assessment year and conduct date matter
The transition is not resolved by looking only at the date a complaint was filed. The relevant analysis may involve the date of the alleged offence, the assessment year, when proceedings began, and the commencement language of the new Act. Published transition material states that an assessment year already begun under the 1961 Act remains governed by that Act. That rule must be applied to the facts of the individual matter, including any savings clause or procedural provision that affects prosecution.
For that reason, a document referring to “section 279” may correctly describe an old-Act prosecution even after 1 April 2026, while the same number in a new-Act document may refer to income escaping assessment. Always read the section title, Act name and transition provision together.

The Department’s prosecution tutorial describes a separate rule for the section 280 offence concerning disclosure by a public servant: prosecution cannot be instituted without the previous sanction of the Central Government. This is not the same authority structure as section 279(1).
Recommended Free Tools
Section 280 should therefore not be used to argue that every Income-tax Act prosecution requires Central Government sanction, nor should the section 279 list be applied automatically to a section 280 allegation. The exact offence and the version of the Act in force for the matter must be identified first.

How to check whether a prosecution has the required authority
For a real case, use the following sequence rather than relying on the designation printed on a complaint:
- Identify the governing law. Record whether the matter arises under the Income-tax Act, 1961 or the Income-tax Act, 2025, the assessment year, the alleged conduct date and the date proceedings began.
- Identify the offence. Match each charge to the precise section. Confirm that it falls within the prosecution provision requiring previous sanction, or determine whether a distinct rule such as section 280 applies.
- Locate the sanction order. Obtain the signed order, not merely a forwarding letter, internal note or statement that approval was granted.
- Check the signatory’s statutory capacity. Compare the signatory with the sanctioning-authority list in the governing Act. If authority is said to arise from delegation, obtain the delegation or direction and confirm that it covered the relevant offence and period.
- Check sequence and dates. Compare the sanction date with the institution of the complaint and any amendment or fresh complaint. A direction to investigate or a proposal to prosecute is not the same document as previous sanction.
- Read the order for the actual case. Confirm that it identifies the assessee, assessment year, alleged offence and material considered. The legal effect of defects depends on the governing statute and case law; it cannot be determined from the title of the document alone.
- Check transition provisions. If the file spans 1 April 2026, verify the official current Act, repeal clause, savings language and any provision preserving proceedings under the 1961 Act.
What this rule does—and does not—establish
The statutory framework establishes who could grant prior sanction under the 1961 Act and separates that function from senior officials’ direction-making and compounding powers. It does not, without the case record, establish whether a named officer had a valid delegation, whether a particular sanction order was properly issued, or whether a prosecution is liable to be quashed.
Those conclusions require the complete complaint, sanction order, relevant assessment and penalty records, delegation instruments, dates and the Act applicable to the alleged conduct. A court may also apply authorities interpreting defects in sanction, curing provisions or procedural prejudice. General information about section 279 cannot replace that case-specific analysis.
