The enactment of the Income-tax Act 2025 marks a major structural overhaul of India's direct tax system, completely renumbering and consolidating the Tax Deducted at Source (TDS) and Tax Collected at Source (TCS) provisions effective from the financial year 2026-27 (Assessment Year 2027-28). While the underlying rates and thresholds remain largely aligned with the previous 1961 Act, salary TDS moves to Section 392, resident non-salary TDS consolidates under Section 393, and TCS provisions move to Section 394. Deductors must urgently map their financial software and systems to prevent defaults.
Background and Rationalisation of the 2025 Act
The Income-tax Act 1961 had grown increasingly complex over six decades of annual amendments. The TDS chapters in particular had become fragmented, containing dozens of standalone sections (e.g., 194C, 194J, 194I, 194H) with disparate rates, definitions, and thresholds. To simplify compliance and reduce litigation, the Income-tax Act 2025 consolidates these provisions into a streamlined structure. The renumbering is not merely cosmetic; it groups related withholding taxes into consolidated sections, making system updates mandatory for all corporate deductors, CAs, and tax professionals in India.
Concordance Table: Old Sections (1961) vs. New Sections (2025)
Below is the official concordance table mapping the commonly used withholding tax sections of the 1961 Act to the renumbered provisions under the Income-tax Act 2025:

System Transition Checklist for Enterprise ERPs
Because every TDS tax payment must cite the correct statutory section under the 2025 Act beginning April 1, 2026, corporate tax departments and accounting teams must execute a structured migration plan:
- ERP Master Data Remapping: System administrators must modify the TDS tax codes in accounting software (SAP, Oracle, Zoho Books, Tally Prime) to reference the new 2025 Act sections.
- Invoice Template Updates: Revise accounts payable workflow templates to ensure that vouchers generate TDS provisions pointing to the sub-clauses of Section 393 instead of the legacy 194 series.
- Agreement & Contract Audits: Update standard vendor contracts, service agreements, and employment letters to reference Section 392 and Section 393 in tax indemnity clauses.
- Form 16/16A & quarterly returns: Ensure your e-TDS filing utility is updated to the latest NSDL schema reflecting the 2025 Act structures.
Impact on Individual Taxpayers and Salary Earners
For employees, the transition is designed to be seamless, but it requires awareness. While the actual tax calculations under the new tax regime continue to follow the standard income brackets, the Form 16 issued by employers at the end of the year will cite Section 392. Taxpayers filing their ITRs must cross-check their Form 26AS and AIS to ensure that the taxes deducted by their employers are credited under Section 392, as any mismatch could lead to processing delays by the Centralized Processing Centre (CPC).
Worked Example: System Remapping and Multi-Payment Processing
Let us consider a corporate transition scenario for **Join Commerce Private Limited (JC)**. In April 2026, JC receives the following bills from vendors:
- Bill A (Professional Services): Rs. 1,50,000 from an advisory consultant.
- Bill B (Office Space Rent): Rs. 2,50,000 from a commercial landlord.
Legacy Processing: Under the 1961 Act, the accounts team would have mapped Bill A to Section 194J (10% TDS = Rs. 15,000) and Bill B to Section 194I (10% TDS = Rs. 25,000).
Updated Processing: Under the Income-tax Act 2025, the software must process:
- Bill A is routed to **Section 393(1)(e)** for Professional Fees. The system deducts TDS at 10% on Rs. 1,50,000 = **Rs. 15,000**.
- Bill B is routed to **Section 393(1)(c)** for Rent. The system deducts TDS at 10% on Rs. 2,50,000 = **Rs. 25,000**.
The challans are deposited under the minor head 200, referencing the new code structures. If the ERP still points to the old 194 series, the IT department's portal will reject the quarterly e-TDS filing or flag it as an invalid section deduction, leading to interest under Section 399(3) (old Section 201(1A)). Over the course of the financial year, this client ensures all of its 500+ vendor transactions are mapped accurately to the new codes, achieving 100% compliance with zero notices.
Key Takeaways
- The Income-tax Act 2025 completely renumbers and rationalizes direct tax withholding.
- Salary TDS moves to Section 392, while non-salary provisions consolidate as sub-clauses of Section 393.
- Ensure ERP systems and tax codes are updated prior to the April 1, 2026 effective date.
- Incorrect section citations in tax challans will trigger system defaults and interest penalties.
