Income Tax Act 2025: What Changes April 1, 2026 for Compliance

On April 1, 2026, India's income tax system undergoes its largest legislative overhaul in decades. After 65 years, the Income Tax Act 1961 is being repealed and replaced by the new Income Tax Act 2025. For individuals, businesses, and tax professionals, understanding these changes is critical to ensure compliance.

Why the Change Happened

The Income Tax Act 1961, with its 819 sections and 47 chapters, had become outdated, repetitive, and difficult to navigate. Over six decades, countless amendments created inconsistencies and redundancy. The new Income Tax Act 2025 simplifies the law to 536 sections arranged in logical sequence, removing over 500 rules from the old Income Tax Rules 1962 and consolidating them into just 333 rules in the new Income Tax Rules 2026.

Key Structural Changes

The new Act eliminates redundant provisions, reorganizes rules thematically, and uses plain-language drafting to improve accessibility. All TDS (Tax Deducted at Source) sections have been consolidated. Instead of citing multiple section numbers like 194C, 194J, and 194I, taxpayers will now use numeric payment codes 1001 to 1067 for TDS payments and return filings. This standardized system applies uniformly across e-payment, challan generation, and return filing.

Critical Compliance Rules

Any tax event occurring on or before March 31, 2026, including salary payments, rental receipts, and property sales, remains governed by the old Income Tax Act 1961. If the same event occurs on or after April 1, 2026, the new Income Tax Act 2025 applies. This bifurcation is crucial: a property sale completed on March 31, 2026 follows the old rules; the same sale on April 1, 2026 follows the new rules. Taxpayers must carefully document the date of each taxable event.

TDS Certificate Changes

Employees accustomed to receiving Form 16 TDS certificates will now receive Form 130 under the new rules. This form serves the same purpose but under the new Act's numbering system. Employers must begin issuing Form 130 certificates from the 2026-27 assessment year (for financial year 2025-26 salaries paid after March 31, 2026).

Important Changes to Specific Rules

Section 194IA (Tax Deduction on Property Purchase) has been revised. When a resident buys immovable property from a non-resident, TDS must now be deposited using the buyer's PAN, not the seller's TAN. This change affects real estate transactions and requires buyer compliance.

Practical Checklist for April 1, 2026

Review all pending tax matters that straddle March 31 and April 1, 2026. Clarify with your tax advisor which law governs each transaction. Update your accounting software to reflect the new TDS payment codes (1001-1067 instead of section numbers). Ensure HR departments begin issuing Form 130 for April 2026 salaries. Verify compliance with Section 194IA if your business involves property transactions with non-residents.

Conclusion

The transition to the new Income Tax Act 2025 is not a mere renumbering—it represents genuine legal change. Proper planning now, before April 1, 2026, will prevent compliance errors and unnecessary scrutiny from the tax authorities.
