TDS Notices — How Do You Reconstruct the Reasoning Behind a Rate?

Yes, the issue is genuine. In many cases, TDS notice handling requires reconstructing the logic from vendor master, contracts, PAN status, thresholds, and supporting records because most systems store the result, not the full reasoning trail.

Thank you for this — really helpful to hear from someone who handles this in practice.

Two follow-up questions if you don't mind:

1. When you reconstruct the logic for a notice, roughly how long does it typically take per transaction? Is it hours or days?

2. Do your clients (or their ERPs) typically have any of this stored — or is it always a reconstruction from scratch?

The Income Tax Act 2025 renumbered all TDS sections from April 1, 2026, so Section 194J is now Section 393 and Section 194C is now Section 392 ,  if your notice references an old section number while your returns used the new ones, that often explains the mismatch rather than the rate itself being wrong. For reconstructing the rate, you need three things: the payment date, the nature of the payment (contract vs. professional vs. salary), and whether the payee had a lower-deduction certificate in force at that time. If the rate itself is disputed, the assessing officer's worksheet in the notice will show you what rate they expected so you can compare directly against the section and thresholds. The new section numbering and how TDS certificates changed this year are covered in this [Form 130 TDS certificate guide](https://taxgarden.in/blog/form-130-replaces-form-16-tds-certificate-2026).

Handling Section 201 TDS notices involves a difficult backward-reconstruction process because standard ERPs store outcomes rather than decision logic (such as point-in-time PAN status, YTD cumulative thresholds, and contract classifications). With the implementation of the Income-tax Act, 2025 and its updated section numbering, notice mismatches have become even more layered, making automated, immutable decision-trail logging a valuable emerging requirement for modern tax compliance tech

Yes, reconstruction can be a real issue where the ERP retains only the deduction outcome. For a Section 201 query, the useful evidence is transaction-dated: the payment or credit details, applicable section and rate, deductee classification, PAN status, threshold/YTD computation, and the basis for any override or exception. Vendor-master settings and emails may help, but can be insufficient if they do not show what was known and applied on the transaction date. The extent of the gap will vary by system and the quality of retained records.

A decision log captured at calculation time could help, provided it is traceable to the underlying transaction and preserves the inputs and rule version used. It would be worth testing whether the API integrates with existing ERP controls and supports review, correction and audit trails; the Income-tax Act, 2025 framing also makes the applicable effective dates and transition treatment important.

This fits naturally into the TDS review and notice-response workflow, where transaction-level evidence can make rate decisions easier to explain. Manual reconstruction across ledgers, master data and email trails is difficult; automation can reduce repetitive work while professional judgment remains in control.
