Income Tax Act, 2025 Replaces “May” with “Shall”: Has the Assessing Officer Lost His Discretion?
A Three-Letter Change That Could Transform Tax Assessments
The Income-tax Act, 2025 has brought numerous structural and drafting changes. While many of them are visible and widely discussed, one seemingly insignificant amendment may have far-reaching consequences for taxpayers, tax professionals, and the Income Tax Department alike.
The legislature has replaced the word “may” with “shall” in the provisions dealing with unexplained income. This three-letter substitution may fundamentally alter the manner in which additions under unexplained cash credits, investments, expenditure and similar provisions are made.
The question is simple but significant:
Has the Assessing Officer’s discretion been taken away under the new law?
The Position under the Income-tax Act, 1961
Sections 68 to 69D of the Income-tax Act, 1961 dealt with unexplained cash credits, unexplained investments, unexplained money, unexplained expenditure and hundi transactions.
The common expression used in these provisions was:
«”such sum may be charged to income-tax.”»
The use of the word “may” was deliberate.
It empowered the Assessing Officer (AO) to exercise judicial discretion after considering the facts and circumstances of each case. Merely because an explanation was found unsatisfactory did not automatically compel the AO to make an addition.
The officer could evaluate:
– the surrounding circumstances,
– the conduct of the taxpayer,
– the genuineness of the transaction,
– financial realities, and
– overall evidence available on record.
Thus, the assessment was intended to be a quasi-judicial exercise rather than a mechanical one.
What Has Changed in the Income-tax Act, 2025?
The corresponding provisions have now been renumbered as Sections 102 to 106.
The crucial change is that the statute now provides that the unexplained amount “shall be charged” to income-tax if the explanation is absent or not satisfactory.
The replacement of “may” with “shall” appears simple.
Legally, however, it is a substantial shift.
Ordinarily, the word “shall” is regarded as mandatory, while “may” confers discretion unless the context indicates otherwise.
If interpreted literally, the Assessing Officer would no longer have the liberty to refrain from making an addition once the explanation is considered unsatisfactory.
Impact on the Landmark Judgment in P.K. Noorjahan
One of the most celebrated decisions on this issue is the Supreme Court ruling in CIT v. P.K. Noorjahan (103 Taxman 382).
The Court specifically observed that Parliament had consciously replaced the word “shall” with “may” while enacting Section 69, thereby conferring discretion upon the Assessing Officer.
The Supreme Court held that even if the explanation was not satisfactory, the AO was not bound to make an addition in every case.
That judgment has protected genuine taxpayers for more than three decades.
However, the statutory foundation on which the decision rested has now changed.
If the legislature has consciously restored the word “shall”, an important question arises:
Can the ratio of P.K. Noorjahan continue to apply under the Income-tax Act, 2025?
This issue is likely to become the subject matter of future litigation.
Practical Consequences for Taxpayers
The amendment could significantly alter assessment proceedings.
1. Greater Documentation Requirements
Taxpayers will need to maintain stronger documentary evidence supporting every credit, investment and expenditure.
Even minor deficiencies may become costly if additions become mandatory.
2. Increased Importance of Source Verification
The source of funds, and in many cases even the source of the source, may receive greater scrutiny.
Incomplete documentation could lead to automatic additions.
3. Reduced Scope for Equitable Considerations
Earlier, genuine hardship, practical business realities or bona fide mistakes could sometimes persuade an Assessing Officer not to invoke these provisions.
If “shall” is interpreted strictly, such equitable considerations may no longer influence the assessment.
4. Higher Litigation
Ironically, a change intended to simplify assessments may increase litigation.
Taxpayers may challenge whether “shall” should always be read as mandatory, particularly where rigid interpretation results in injustice.
Is “Shall” Always Mandatory?
Not necessarily.
Indian courts have consistently held that statutory interpretation depends upon legislative intent and the consequences flowing from a particular interpretation.
The Supreme Court has, in several cases, observed that the words “may” and “shall” are not always decisive by themselves.
If reading “shall” literally leads to absurdity, injustice or defeats the object of the legislation, courts may still interpret it as directory rather than mandatory.
Therefore, although the amendment undoubtedly strengthens the Revenue’s position, the final legal position will ultimately depend upon judicial interpretation.
A New Era of Tax Compliance
The amendment serves as an important reminder that compliance under the Income-tax Act, 2025 is likely to become increasingly documentation-driven.
Taxpayers can no longer rely merely upon equitable considerations or administrative discretion.
Every financial transaction should be capable of being supported by proper evidence.
The emphasis is clearly shifting from explaining transactions after scrutiny to maintaining comprehensive documentation from the very beginning.
Conclusion
Sometimes, the biggest legal changes are hidden in the smallest words.
The substitution of “may” with “shall” may appear to be a mere drafting exercise, but its practical implications could be enormous.
Whether Parliament intended to eliminate the Assessing Officer’s discretion or whether courts will continue to preserve a degree of flexibility remains to be seen.
Until judicial precedents emerge under the Income-tax Act, 2025, taxpayers and tax professionals would be well advised to assume that the law has become stricter and ensure that every credit, investment and expenditure is backed by complete and credible documentation.
In tax law, three letters can change the entire landscape. The transition from “may” to “shall” could well become one of the most debated interpretational issues under the Income-tax Act, 2025.
