Union Budget 2026-27 — Part B: Tax Proposals, New Income Tax Act & Fiscal Consolidation

ECONOMY | MARCH 2026

The New Income Tax Act 2025: A Paradigm Shift

The most consequential announcement in Part B of Budget 2026-27 is the Income Tax Act 2025, replacing the six-decade-old Income Tax Act, 1961, effective April 1, 2026. This represents the most significant overhaul of India’s direct tax architecture since independence, responding to decades of judicial criticism about the complexity of the existing statute.

The new Act’s key judicial implications include:

• Simplified assessment procedures: Reducing litigation backlog (currently over 4 lakh cases pending in Income Tax Appellate Tribunals)
• Faceless assessment continuation: Building on the e-assessment framework upheld in multiple High Court decisions
• Reduced discretionary powers: Addressing the Supreme Court’s concern in Principal Commissioner v. Abhisar Buildwell (2023) about arbitrary reassessment proceedings
• Clearer penalty provisions: Following the principle of nulla poena sine lege (no punishment without law)

SEZ to DTA Conversion: Reviving Export Zones

The provision allowing Special Economic Zone (SEZ) to Domestic Tariff Area (DTA) conversion addresses the chronic underutilisation of SEZ infrastructure. The SEZ Act, 2005 and SEZ Rules, 2006 created export-focused enclaves, but many units struggled with export obligations. The Supreme Court in Mahindra & Mahindra v. Union of India (2023) examined the legality of retrospective withdrawal of SEZ benefits.

The DTA conversion allows SEZ units to sell domestically without surrendering their infrastructure investments, though they forfeit tax concessions. This has implications for customs law (re-classification of goods), GST (zero-rated supplies becoming taxable), and labour law (change in employment conditions).

Securities Transaction Tax (STT) Hike and Market Impact

The STT increase triggered a Sensex crash of approximately 2,000 points on Budget day — one of the sharpest intra-day declines in recent history. From a legal perspective, the STT hike raises questions about:

The STT, first introduced in 2004, is levied under the Securities Transaction Tax Act (originally Chapter VII of the Finance Act, 2004). Unlike capital gains tax, STT is a transaction-based levy regardless of profit or loss, making it regressive in nature.

Fiscal Consolidation: The FRBM Compliance Path

The Fiscal Responsibility and Budget Management (FRBM) Act, 2003 provides the statutory framework for fiscal discipline. Budget 2026-27 demonstrates continued adherence to the fiscal consolidation glide path:

• Fiscal Deficit: 4.3% of GDP — progressing toward the FRBM target of 3%
• Revenue Deficit: 1.5% of GDP — indicating improved quality of expenditure
• Debt-to-GDP: 55.6% currently, targeting 50±1% by 2030-31
• Gross Borrowing: Rs 17.2 lakh crore

The FRBM Act, amended in 2018 following the N.K. Singh Committee recommendations, allows escape clauses for fiscal deficit deviation of up to 0.5% in exceptional circumstances. The justiciability of FRBM targets remains legally ambiguous — while the Act creates a statutory obligation, the Supreme Court has not directly adjudicated whether fiscal deficit targets are enforceable through judicial review.

Budget Size and Sectoral Allocations

The total Budget outlay of Rs 53.47 lakh crore reveals strategic priorities through sectoral allocations:

• Defence: Rs 5.94 lakh crore (~11.1% of total Budget) — governed by the Defence Procurement Procedure (DPP) and strategic partnership model. The allocation includes modernisation funds subject to parliamentary oversight through the Standing Committee on Defence
• Transport: Rs 5.98 lakh crore — marginally exceeding defence, reflecting the infrastructure-first approach. This encompasses railways, highways (under NHAI governed by the National Highways Authority of India Act, 1988), and civil aviation

Constitutional Principles Governing the Budget

The budget process engages several constitutional provisions that are frequently tested in judicial services examinations:

The distinction between a Money Bill (Art. 110) and a Finance Bill has been contentious. The Supreme Court in the Aadhaar case (K.S. Puttaswamy v. Union of India, 2018) examined whether the Aadhaar Bill was correctly classified as a Money Bill, though the majority did not definitively resolve the Speaker’s certification jurisdiction. This constitutional ambiguity persists and may be relevant for future tax legislation challenges.

Debt Management and Market Borrowing

The gross borrowing of Rs 17.2 lakh crore has implications for monetary policy coordination between the RBI and the Finance Ministry. The RBI Act, 1934 (Section 21) designates RBI as the government’s banker, and the Open Market Operations (OMOs) framework manages the yield curve impact of government borrowing. The proposed Public Debt Management Agency (PDMA) — long debated but not yet established — would separate debt management from monetary policy.

PCS-J Examination Perspective

For judicial services aspirants, Part B of the Budget raises critical questions on the legislative competence for taxation (Union List Entry 82-84), the Money Bill controversy (Art. 110 — Speaker’s certification vs. Rajya Sabha’s role), the justiciability of fiscal targets under the FRBM Act, and the transition to the new Income Tax Act 2025. The STT hike litigation potential engages Art. 14 (equality), Art. 19(1)(g) (trade rights), and Art. 265 (tax authority). PCS-J Mains may frame questions on whether fiscal populism (excessive borrowing) violates intergenerational equity — a principle the Supreme Court recognised in environmental jurisprudence under Art. 21.
