Section 3 — Previous Year Defined

STATUTORY ARCHITECTURE — 18-ROW MAP

HISTORICAL CONTEXT — UNIFICATION OF THE PREVIOUS YEAR

Section 3 in its current form derives from the Direct Tax Laws (Amendment) Act, 1987, which unified the 'previous year' across all sources of income for AY 1989-90 onwards. Prior to this unification, the previous year could differ depending on the source of income — for example, a salary-earner's PY could be the financial year (April-March), while a businessman's PY could be his accounting year (e.g., July-June or October-September), and capital gains could be reported on a calendar-year basis. This caused administrative complexity, compliance errors, and inter-source timing arbitrage. The 1987 reform unified the PY as the financial year (1-April to 31-March) immediately preceding the AY for all sources.

The transitional provisions for businesses with non-April-to-March accounting years were addressed by the proviso to section 3 — newly set-up businesses or new sources have a 'broken' PY beginning on the date of set-up / new-source emergence and ending on 31-March of the same FY. This carve-out continues to be operative for any business newly set up mid-year (e.g., 15-October-2024 → PY 2024-25 runs from 15-10-2024 to 31-3-2025 — a 5.5-month PY; subsequent PYs are full April-March).

Section 3 interacts intensely with section 4 (charge) and section 5 (scope). The charge under section 4 is on the total income OF THE PY, payable for the AY. The scope under section 5 identifies WHICH income enters total income — anchored on the PY. Section 6 (residential status) is determined for each PY independently. The section-3 PY is thus the temporal anchor for the entire computational, charging, and scope machinery.

The transition to the Income-tax Act, 2025 replaces the PY-AY duality with a single 'tax year' concept under section 3 / section 4 of the 2025 Act. The tax year is anchored on the same April-March financial-year periodisation; the abstract distinction is that the 'tax year' is forward-looking rather than backward-looking. Substantive operation is identical — businesses still report on April-March; deductions still must be claimed within the tax year; the rate-prescription mechanism (annual Finance Act) continues. Section 536 saving clause preserves PY-AY framework for pending matters.

FINANCE ACT AMENDMENT TIMELINE

■ FA 1962 — Section 3 came into force; multiple-PY framework inherited from 1922 Act.

■ Direct Tax Laws (Amendment) Act, 1987 — Unification of PY with the financial year (effective AY 1989-90).

■ FA 1989 — Newly-set-up-business carve-out (proviso) clarified.

■ FA 1990-2000s — Multiple minor refinements; PY framework substantively stable.

■ FA 2018-2024 — Faceless assessment + procedural changes operate on the PY framework but do not alter section 3.

■ FA 2025 — No substantive change to section 3.

■ Income-tax Act, 2025 — Section 3 successor adopts 'tax year' terminology, operative 1-4-2026.

JUDICIAL EVOLUTION — VERIFIED LANDMARK AUTHORITIES

▸ Commissioner of Income-tax v. Excel Industries Ltd. (2013) 358 ITR 295 ; (2014) 2 SCC 1 (Supreme Court)

Facts. The assessee, an export-oriented unit, received DEPB licences and Advance Licences. The Department sought to tax the value of these incentives on accrual at the time of issue; the assessee contended that no income accrued until the licence was actually used or sold.

Issue. When does income accrue under the mercantile system — at the moment a right is created, or at the moment the right becomes enforceable as a debt?

HELD. Income accrues only when there is a corresponding liability of the other party. Mere creation of a contingent or unmatured right does not amount to accrual; the right must crystallise into a debt before tax incidence.

“Income accrues when there arises in favour of the assessee a debt — when there is a corresponding liability of the other party to pay the amount. It is not enough that the right has come into being; the right must ripen into a debt.”

Relevance. Anchor for accrual-vs-receipt timing disputes under section 5 / section 145 — relevant for retention monies, export incentives, contingent claim settlements, milestone-based contracts.

▸ E.D. Sassoon & Co. Ltd. v. Commissioner of Income-tax (1954) 26 ITR 27 ; AIR 1954 SC 470 (Supreme Court — Constitution Bench)

Facts. The assessee, a managing-agent firm, transferred its managing-agency rights to a successor mid-year. The Department sought to tax the entire year's managing-agency commission in the hands of the assessee, on the ground that the right accrued only on the completion of the year. The assessee contended that the commission for the part of the year actually served had accrued month-by-month.

Issue. When does income accrue under the mercantile system — at the point of rendering service, or only on completion of the contractual cycle that fixes the quantum?

HELD. Income accrues only when there is a vested right to receive it, however remote the future date of receipt. Mere expectation, however confident, is not accrual. For income to accrue, the right must be vested — not contingent on future performance, and not subject to defeasance.

“It is clear, therefore, that income may accrue to an assessee without the actual receipt of the same. If the assessee acquires a right to receive the income, the income can be said to have accrued to him though it may be received later on… But unless and until there is created in favour of the assessee a debt due by somebody, it cannot be said that he has acquired a right to receive the income.”

Relevance. Foundational on the meaning of 'accrual' under section 5 (and section 4 charge timing) — anchors arguments around mid-year contracts, milestone-based engagements, contingent rights, and retention monies.

▸ Commissioner of Income-tax v. Vatika Township Pvt. Ltd. (2014) 367 ITR 466 ; (2015) 1 SCC 1 (Supreme Court — 5-Judge Constitution Bench)

Facts. The Department sought to apply a surcharge provision retrospectively to block-period assessments. The assessee contended that the amendment was substantive and could not have retrospective operation absent express legislative direction.

Issue. Whether amendments to taxing statutes operate prospectively unless the legislature has expressly or by necessary implication conferred retrospective effect.

HELD. The Constitution Bench reaffirmed the general rule against retrospectivity of taxing statutes. A taxing provision must be construed prospectively unless the language compels otherwise; mere insertion or substitution by amendment is not sufficient to deny vested rights.

“Of the various rules guiding how a legislation has to be interpreted, one established rule is that unless a contrary intention appears, a legislation is presumed not to be intended to have a retrospective operation.”

Relevance. Anchor authority for any argument that an amendment to a charging or computational provision must apply only from the AY notified — useful in transitional disputes around FA 2025 and the 1961 → 2025 changeover.

▸ K.P. Varghese v. Income-tax Officer, Ernakulam (1981) 131 ITR 597 ; (1981) 4 SCC 173 (Supreme Court — 3-Judge Bench)

Facts. Section 52(2) (since deleted) deemed sale consideration to be FMV where FMV exceeded the declared consideration by 15%. The Department applied it on a literal reading even when the assessee had not in fact received more than the declared price.

Issue. Whether a deeming provision in a charging schema can be construed literally where its plain reading produces a result manifestly contrary to legislative object.

HELD. The Court read down section 52(2) to apply only where the assessee had actually received consideration in excess of the declared sum. A literal construction yielding absurd or unjust results must yield to an object-based interpretation; the CBDT's contemporaneous Circular No. 96 was held binding on the Revenue.

“It is well settled that a literal construction of a statutory provision ought not to be adopted if it produces a manifestly unjust result… Where a literal construction creates an anomaly, the courts will adopt that construction which avoids the anomaly.”

Relevance. Anchor authority for purposive construction of deeming fictions across the 1961 Act — applies wherever a deeming clause (e.g., s. 50C, s. 56(2)(x), s. 2(22)(e)) yields a result contrary to legislative purpose.

▸ Commissioner of Income-tax v. B.C. Srinivasa Setty (1981) 128 ITR 294 ; (1981) 2 SCC 460 (Supreme Court)

Facts. The assessee transferred goodwill of a self-generated nature. The Department sought to tax the consideration as capital gains; the assessee contended that no cost of acquisition could be ascertained, hence the computation provisions failed.

Issue. Whether capital gains arises where the asset has no ascertainable cost of acquisition — i.e., whether the charging provision can be invoked independently of a workable computation provision.

HELD. The charging section and the computation provisions form an integrated code; if the computation provisions cannot apply (because the cost is incapable of ascertainment), the charge itself fails. Self-generated goodwill is not taxable as capital gains.

“The charging section and the computation provisions together constitute an integrated code. When there is a case to which the computation provisions cannot apply at all, it is evident that such a case was not intended to fall within the charging section.”

Relevance. Anchor for the 'charge fails when computation fails' doctrine — useful in valuation impasses, self-generated assets, and computational ambiguity (though now largely overtaken by section 55(2)(a)(i) deeming cost as nil).

CBDT CIRCULARS — SECTION 3 ECOSYSTEM

▸ CBDT Circular No. 14(XL-35) of 1955 dated 11 April 1955

Subject. Duty of officers to assist assessees in claiming and securing relief

Substance. Foundational circular directing that the AO should not exploit assessee ignorance to deny legitimate reliefs; officer is required to draw attention to refunds or reliefs to which the assessee is entitled. The circular has been judicially noted in several appellate decisions and remains operative for first-appellate practice.

▸ CBDT Circular No. 549 dated 31 October 1989

Subject. Explanatory notes — Finance Act 1989 amendments (incl. PY unification)

Substance. Explained the FA 1987 / FA 1989 amendments unifying the previous year with the financial year preceding the AY, including transitional provisions for assessees with different accounting years. Useful in any controversy on the timing of accrual / chargeability for early post-1989 AYs.

▸ CBDT Circular No. 5 of 2014 dated 11 February 2014

Subject. Section 14A — dis-allowance even where no exempt income earned (since modulated)

Substance. Initially directed AOs to apply Rule 8D disallowance under section 14A even where no exempt income was earned in the year; subsequently modulated by Cheminvest (Del HC) and Maxopp (SC). FA 2022 amendment to section 14A re-asserted the position but remains under litigation.

WORKED EXAMPLES — APPLICATION OF SECTION 3

PRACTITIONER PLANNING NOTES — SECTION 3

■ PY-AY alignment — for AY 2025-26, PY = 1-4-2024 to 31-3-2025; do not confuse with calendar year.

■ Newly-set-up business — PY begins on date of set-up; pro-rate depreciation for assets used < 180 days.

■ New source mid-year — separate broken-PY for that source.

■ Discontinued business — s. 176(3) accelerated assessment; PY framework yields.

■ Foreign-source income for ROR — converted to INR at TT buying rate on date of accrual / receipt within the PY.

■ Companies Act / Books-of-accounts year — may differ from tax PY; reconcile for tax purposes.

■ Co-operative society / firm — may have historical July-June books; restate for April-March tax PY.

■ Capital gains — date of transfer fixes the PY of capital-gain recognition; documents must be PY-aligned.

■ Section 89 spread-back — for arrears income, claim relief by spreading back to the PYs to which it relates; Form 10E.

■ Loss carry-forward — losses of a PY can be carried forward; track origin-PY to apply 8-year / 4-year / lifetime limits per section.

■ Belated returns under s. 139(4) — for the AY, but referencing the PY income.

■ Updated return under s. 139(8A) — same PY income, claimed via the updated route within 24-month window of AY-end.

■ Reassessment under s. 147 / 148 / 148A — re-opens the PY income for AYs within section 149 time-bar.

■ Books retention under s. 44AA / Rule 6F — 7 years from end of relevant PY; for foreign assets, 17 years per Black Money Act limitation.

■ Annual practitioner discipline — PY-end (31-March) compliance calendar covering advance tax / Form 60 / TDS reconciliation / advance-tax challan deposit.

LITIGATION DEFENCE — SECTION 3 ARGUMENTS

■ PY definition — argue strict April-March periodisation; AO cannot impose alternative period.

■ Newly-set-up proviso — produce date of set-up evidence (incorporation / first sale / first employee); preserve broken-PY status.

■ New-source carve-out — argue that mid-year new source has separate broken-PY; preserve depreciation / deduction pro-rating.

■ Excel Industries accrual anchor — argue that PY-end accruals require vested rights; AO cannot premature-charge.

■ ED Sassoon vested-right anchor — argue that contingent rights are not income in the PY.

■ Vatika Township prospective anchor — argue that any FA amendment to PY-related provisions applies from the AY notified.

■ K.P. Varghese object-based anchor — argue against AO's literal PY computation that produces unjust results.

■ BC Srinivasa Setty anchor — if computation provisions cannot be applied for a PY event, the charge fails.

■ Section 89 spread-back — argue for spread-back to multiple PYs where income relates to past services.

■ Section 139(8A) updated return — argue for accept of updated return within the window; AO cannot reject without statutory basis.

■ Reassessment time-bar — argue strict s. 149 time-bar; AYs beyond limit cannot be reassessed.

■ Books-retention period — argue 7-year limit (or 17-year for BMA matters); preserve against AO's wider demand.

■ Mathuram Agrawal strict-construction anchor — argue against AO's PY expansion beyond text.

■ Section 176(3) defence — for discontinued business, argue ONLY business income subject to accelerated assessment; other income remains in regular PY.

■ Multiple-PY-source historical defence — for pre-1989 PYs, argue per pre-1987 framework.

■ Companies Act alignment — argue that tax PY is April-March regardless of books year; defend against AO who imposes books-year as PY.

PROCEDURE — APPLYING SECTION 3

Step 1. Identify the PY

For continuous-source assessees — April-March immediately preceding the AY.

Step 2. Identify the AY

PY + 1 year; e.g., PY 2024-25 → AY 2025-26.

Step 3. Verify newly-set-up business / new source

If applicable, apply s. 3 proviso — broken-PY beginning on date of set-up / new source emergence.

Step 4. Verify discontinued business

If applicable, apply s. 176(3) accelerated assessment; rest of PY does not have business income.

Step 5. Compute income head-wise for the PY

Salaries / HP / PGBP / CG / OS — each head computed for the PY.

Step 6. Apply currency conversion (Rule 115)

Foreign-source income converted to INR at TT buying rate on date of accrual / receipt within PY.

Step 7. Compute residential status under s. 6

For the PY in question — independently determined.

Step 8. Apply scope filter under s. 5

Based on residential status, filter PY income.

Step 9. Compute total income

Aggregate head-wise + apply Chapter VI-A deductions.

Step 10. Apply charge under s. 4 at AY's Finance Act rates

Slab / flat / special rates from Finance Act for the AY.

Step 11. Reconcile TDS / TCS / advance tax with PY computation

Form 26AS / AIS for the relevant PY; sec 199 credit.

Step 12. Quantify interest under s. 234A / B / C

Computed against PY tax liability; for delay in return / advance-tax shortfall.

Step 13. Pay self-assessment tax

Under s. 140A before filing return.

Step 14. File ITR for the AY

ITR-1 to 7 depending on assessee category; due date per s. 139(1).

Step 15. Preserve PY-related working papers

7 years from PY-end; 17 years for BMA-safe foreign-asset matters.
