Income Tax Act 2025 · First filing due 31 July 2026· कर

24Q is now Form 138. 26Q is now Form 140. Q1 is due in weeks.

From FY 2026-27 the TDS return family gets new numbers under the Income Tax Act 2025 — and the first quarterly filing on the new forms lands 31 July 2026. Here is the complete old-to-new form map, the due-date calendar, the Sec 392/393 mechanics behind each form, and what auditors should test in transition year one.

The substantive risk is mapping, not filing: every old section your TDS software carried (194C, 194J, 194-I…) must land on the right Sec 393 payment code. The rate finder carries the current rates and thresholds; the mapper carries the section concordance.

Forms 138/140, frequently asked

What is Form 138?

The quarterly TDS statement for salary deductions under the Income Tax Act 2025 — the replacement for Form 24Q, effective for financial years from 1 April 2026. Employers deducting under Sec 392 file it quarterly with the same annexure logic 24Q carried: deductee-wise deduction detail plus the Q4 salary detail.

What is Form 140?

The quarterly statement of TDS on non-salary payments to residents — the Form 26Q replacement, governed by Sec 397(3)(b) of the 2025 Act read with Rule 219 of the Income Tax Rules 2026. Every Sec 393 deduction (contractor, professional fees, rent, commission, interest, brokerage) reports here with its payment code.

What are the TDS return due dates for FY 2026-27?

31 July (Q1), 31 October (Q2), 31 January (Q3) and 31 May (Q4) — the same quarterly rhythm as before. The first filing on the new forms is Q1 FY 2026-27, due 31 July 2026.

What is the late-filing fee for the new forms?

₹200 per day of delay, capped at the TDS amount reported in the return — the old Sec 234E discipline carried into the new regime. Interest on late deduction/deposit continues separately at the familiar monthly rates.

Do the old forms apply to old periods?

Yes — corrections and filings for FY 2025-26 and earlier stay on 24Q/26Q/27Q/27EQ under the 1961 Act. The new numbers apply to deductions for periods beginning 1 April 2026. Firms will file in both systems during the overlap.

What should the auditor verify around the transition?

Four things: that Q1 FY 2026-27 onwards was filed on the new forms with Sec 393 payment codes correctly mapped from the old section-wise configuration; that challans reference the new regime consistently; that Form 26AS/AIS credits flowed for deductees after the switch; and that the Form 3CD clause 34 tables for FY 2026-27 audits reconcile to Forms 138/140 rather than 24Q/26Q. TDS software mapping errors in the first year are the predictable finding.
