The Income Tax Act, 2025 repeals the Income Tax Act, 1961 (Section 536) w.e.f. 01.04.2026. One of its most time-sensitive provisions — Section 397(3)(f) — reduces the TDS/TCS correction window from the earlier six-year limit to a strict two years from the end of the relevant tax year. CBDT has formally cautioned all deductors via the TRACES portal: specific FY-quarter combinations are permanently closed as of 31.03.2026. Once that date passes, no further corrections are entertained under any circumstance.
The absence of a hard deadline had led to systemic backlogs and credit mismatches in Form 26AS. The 2024 amendment first introduced a cap; the 2025 Act tightens it further — signalling an unambiguous shift towards accuracy at source. Going forward, corrections are to be the exception, not the norm.
The following periods will NOT be accepted on TRACES from 01 April 2026 onwards:
Going forward: FY 2023-24 (Q4) onwards — 2-year rolling window applies under the new Act.
Under Section 397(3)(f), the correction window for a given quarter closes two years from the end of the tax year in which the original TDS/TCS statement was due (Q4 statements, due 31 May, fall in the following tax year). This gives the following last dates for filing corrections:
Note: Deadlines above assume standard (non-government) deductor due dates. File well ahead of each date to allow for TRACES processing time.
Immediate Operational Effects
Immediate Steps
"The era of deferred correction is over. Accurate TDS at source, filed right and on time, is no longer best practice — it is a legal imperative. Build your compliance rhythm around quarterly reconciliation, not annual cleanup."
