TDS Payment Codes (Sections 392 and 393)
Under the Income Tax Act, 2025, salary TDS moves to Section 392 and all non-salary TDS provisions (the entire 194-series of the old Act) are consolidated into Section 393. TDS challans and quarterly returns reference payment codes 1001 - 1067 instead of section numbers: 1001-1004 salary (Section 392, Form 138); 1005-1038 resident non-salary payments (Section 393(1), Form 140 / Form 141); 1039-1057 non-residents (Section 393(2), Form 144); 1058-1067 Section 393(3). TCS codes under Section 394 start at 1068 (Form 143). Using old section numbers for payments on or after 1 April 2026 will cause portal validation failures. The table below lists common codes only; confirm the code in the e-Pay Tax (ITNS 281N) drop-down before depositing.

Frequently Asked Questions
Which Act governs my ITR for FY 2025-26 (AY 2026-27)?
Income Tax Act, 1961. Even if you file the return after 1 April 2026, the income earned during FY 2025-26 will be assessed under the 1961 Act using the old section numbers (80C, 80D, 87A, 192 etc.). The portal will use “Tab 1 — Forms as per Income Tax Act 1961” for these filings.
Do my pending appeals / assessments under the old Act continue?
Yes — under Section 536(2)(c) of the ITA 2025 (Repeal & Savings), all proceedings pending on 1 April 2026 (assessments, reassessments, appeals, penalty proceedings, prosecutions) continue under the 1961 Act provisions. Any proceeding initiated after 1 April 2026 in respect of a tax year beginning before that date also follows the 1961 Act procedure.
Are tax rates / slab structures changing under the new Act?
No new taxes are imposed by the Income Tax Act, 2025. Slab rates, surcharge, cess, the Rs 1.5L 80C / Section 123 limit, the Rs 60K rebate under Section 156 (old 87A), the Rs 75K standard deduction — all remain identical. The new Act is structural and language-simplification only.
What is the concept of “Tax Year”?
The Income Tax Act, 2025 replaces the dual concept of “Previous Year” (when income is earned) and “Assessment Year” (when it is taxed) with a single concept of Tax Year. Tax Year 2026-27 covers 1 April 2026 to 31 March 2027 — the same year you earn the income and the year it is taxed. For new businesses, the first Tax Year runs from the date of commencement to 31 March of that financial year.
What changes for TDS deductors from 1 April 2026?
Three structural changes: (i) all 60+ non-salary TDS provisions consolidate into Section 393; (ii) TDS challans / returns use payment codes 1001 - 1067 (TCS codes start at 1068) instead of section numbers; (iii) Forms 26QB / 26QC / 26QD / 26QE merge into a single Form 141 with sub-schedules, and quarterly returns move to Forms 138 / 140 / 144 (TCS: 143). Payroll, ERP and accounting software must use the new sections, payment codes and forms for all payments made or credited on or after 1 April 2026; the old 1961 sections and Forms 24Q / 26Q / 27Q continue only for deductions up to 31 March 2026, including their correction statements.
What is the TRACES correction lockout?
All TDS / TCS correction statements for the period FY 2018-19 Q4 through FY 2023-24 Q3 had to be filed on or before 31 March 2026. From 1 April 2026, these years are permanently time-barred on the TRACES portal. From Tax Year 2026-27, Section 397(3) of the ITA 2025 allows corrections only within 2 years from the end of the relevant Tax Year. Plan reconciliations accordingly.
Is the Old Tax Regime discontinued?
No. Both the Old Regime and the New Regime continue under the Income Tax Act, 2025. The New Regime remains the default (Section 202, ITA 2025; old Section 115BAC). From Tax Year 2026-27 there is no separate Form 10-IEA: under Rule 136 of the Income Tax Rules, 2026, the option to opt out of (or withdraw from) the new regime under Section 202 is exercised in the return of income filed under Section 263(1). Form 10-IEA continues only for FY 2025-26 (AY 2026-27) under the 1961 Act. (Form 32 under the 2026 Rules replaces Form 10CCB, not Form 10-IEA.)
This page is a curated reference compiled by SKAG and Associates from publicly-available CBDT notifications and the official gazette. It is not exhaustive — the new Act has 536 sections and the new Rules cover 333+ rules. For specific provisions, please refer to the official text on incometax.gov.in or consult the firm.
