Form 132 and Section 425: The New Act’s Numbers Behind This Week’s Two Deadlines

Published 14 Sept 2026· By Finoscape Editorial Team· 4 min read

Two compliance dates fall this very week that most practitioners will still instinctively describe using pre-2026 terminology — and getting the citation wrong in front of a client, even on something this procedural, is the kind of small error that erodes confidence disproportionately. Both trace back to the Income-tax Act, 2025, in force for Tax Year 2026-27 onward since 1 April 2026.

Form 132 — due today, 14 September 2026, for July 2026 non-salary TDS. Under Section 395(4) of the Income-tax Act, 2025 (Rule 215 of the Income-tax Rules, 2026), Form 132 is a single, consolidated TDS certificate that has quietly absorbed four separate certificates practitioners have issued for years: the erstwhile Forms 16B (TDS on property transfers), 16C (TDS on rent), 16D (TDS on commission, fees or technical services) and 16E (TDS on virtual digital asset transfers). Any deductor who has deducted and deposited TDS on any of these categories must issue Form 132 to the deductee — downloaded and signed via the TRACES portal — within 15 days of the due date for filing the corresponding challan-cum-statement, Form 141. For a July 2026 deduction, that issuance deadline lands today.

Sidebar: the practical trap here isn’t the substance — deduct, deposit, certify hasn’t changed — it’s muscle memory. A firm’s own internal checklist, template engagement letter, or standard client-communication email that still says “please find attached Form 16B” is now describing a certificate that, strictly, no longer exists as a separate form.

Section 425 — the interest provision behind tomorrow’s advance-tax deadline. The second instalment of advance tax for Tax Year 2026-27 falls due tomorrow, 15 September, with the cumulative liability expected to reach 45% of the year’s estimated tax (following the new Act’s own instalment schedule under Section 408 — 15% by 15 June, 45% by 15 September, 75% by 15 December, 100% by 15 March, mirroring the familiar old-Act rhythm exactly, just under a new section number). Shortfall against that cumulative percentage now attracts interest under Section 425 of the Income-tax Act, 2025 — the direct successor to the old Section 234C — at the same simple-interest rate practitioners already know, 1% per month or part of a month on the shortfall. A separate provision, Section 424 (successor to old Section 234B), continues to apply where advance tax paid overall is nil or falls below 90% of the assessed tax for the year.

Why It Matters

None of the substance has changed — the percentages, the dates, and the 1%-per-month interest rate are all carried over intact from the pre-2026 regime. What has changed is every section number a professional would cite in a client letter, a submission, or an internal file note. Citing “Section 234C” for a Tax Year 2026-27 shortfall is not wrong in spirit, but it is now the wrong statutory reference — and precision on exactly this kind of detail is part of what clients are paying for.

Key Takeaways

Form 132, under Section 395(4) of the Income-tax Act, 2025, has replaced Forms 16B, 16C, 16D and 16E as the single TDS certificate for property, rent, commission/fees/technical-service and virtual-digital-asset deductions; today, 14 September, is the issuance deadline for July 2026 deductions.
The advance-tax instalment schedule itself is unchanged in substance (15%/45%/75%/100% by 15 June/September/December/March) but now sits under Section 408 of the new Act.
Interest for shortfall against the cumulative instalment percentage — the old Section 234C — is now Section 425; interest for an overall default or sub-90% payment — the old Section 234B — is now Section 424.
Update client-facing templates, checklists and standard correspondence to the new form and section numbers; the underlying compliance obligations have not changed, but the citations have.

Practical Implications

This is a low-drama but high-visibility update to get right. Firm-wide, this is worth a single checklist pass — engagement letters, standard notice-response templates, and internal SOPs that reference “Form 16B/16C/16D” or “Section 234B/234C” should be updated to the Income-tax Act, 2025 terminology, particularly for anything client-facing generated after 1 April 2026.
