TDS Return Filing: A Quarter-End Checklist for CA Firms

CA reviewing TDS return documents with a calculator

Every quarter, the same pattern repeats in CA firms across India. Challans are paid on time, the deductee list looks complete, and then the statement bounces at validation or comes back from TRACES with a short-deduction default a few weeks later. Most of these problems are not about tax law at all. They come from gaps in the process. AskSolique, which helps Indian CA practices with tds return filing research and wider income tax work, sees the same handful of avoidable errors again and again.

This checklist walks through what a firm should verify before, during and after a quarterly TDS statement goes out, so that the return is filed once and stays filed.

1. Know Which Statement and Which Deadline Applies

The first step sounds basic, yet it is where junior staff most often slip. Each deductor files a separate quarterly statement for each type of payment:

Under the long-standing schedule, the statements for the April–June, July–September and October–December quarters fall due by the last day of the month after the quarter ends (31 July, 31 October and 31 January), and the January–March statement by 31 May. With the Income Tax Act 2025 now in force from April 2026, several section and form references are being remapped, so always confirm the current reference and due date against the latest CBDT notification before you quote it to a client.

A simple master calendar, one row per client and one column per form and quarter, removes most of the “we forgot the 27Q” surprises.

2. Reconcile Challans Before You Prepare the Statement

Most rejected or defaulted statements trace back to challan mismatches. Before anyone opens the return preparation utility, reconcile three things for the quarter:

  1. Books of account — every payment that attracted TDS, with the section, rate and amount deducted.
  2. Challans paid — the BSR code, challan serial number, date of deposit and amount, matched against the OLTAS status on the portal.
  3. Deductee details — PAN, name and the section code for each deductee.

If the total deducted in the books does not equal the total of challans tagged to the statement, stop and fix it first. A short payment or a challan mapped to the wrong quarter will create a demand on the deductor's TRACES account later, and fixing it then takes far longer than fixing it now.

Invalid or missing PANs deserve special attention. A deductee without a valid PAN attracts a higher rate of deduction, and a typo in a valid PAN means the deductee never sees the credit in their Form 26AS. Run a PAN verification on the deductee master every quarter rather than once a year.

3. Prepare, Validate and File Without Shortcuts

Once the data is clean, preparation is mostly mechanical:

Late filing is expensive. A fee is charged for every day of delay until the statement is filed, capped at the amount of TDS, and a separate penalty can apply where a statement is filed very late or with incorrect information. Clients rarely remember that the fee applies even when the tax itself was deposited on time, so it is worth saying so in your quarterly reminder.

4. Handle Corrections Through TRACES the Right Way

No firm files every statement perfectly. When a correction is needed (a wrong PAN, a challan tagged to the wrong deductee, a missed entry), the safe sequence is:

  1. Log in to TRACES and request the consolidated file for the original statement, using the token number and challan details.
  2. Import the consolidated file into the RPU and make only the required changes.
  3. Validate the correction statement with the FVU and upload it.
  4. Recheck the TRACES statement status and the justification report once processing is complete.

The most frequent mistake here is preparing a correction from the firm's own working file instead of the consolidated file. The department's records are the base; the correction has to start from them. If a demand has already been raised, it often makes sense to read the intimation the same way you would read any other notice. The approach in our earlier note on the income tax demand notice under section 143(1) applies here too: identify the exact mismatch before you draft anything.

5. Fit TDS Into the Wider Compliance Calendar

TDS does not sit on its own. The same accounts team is usually handling advance tax, GST returns and the year-end annual filings at the same time. October is a good example: the quarter-two TDS statements fall due in the same weeks that firms are planning ahead for the annual GST return. Keeping the GSTR-9 due date on the same master calendar as the quarterly TDS deadlines lets a manager see the crunch weeks early and assign people before the deadline, not after it.

A shared calendar also makes reconciliations easier. Vendor payments that attract TDS under 26Q usually also appear in GST input credit records, so mismatches spotted in one place often point to errors in the other.

6. Use Technology Where It Actually Saves Time

Software will not make judgement calls for you, but it can take the slow, repetitive parts off your team's desk: checking the correct section and rate for an unusual payment, pulling the latest circular, or comparing the old and new section references under the 2025 Act. Firms that adopt AI built for chartered accountants typically use it for research and first drafts, and keep review, sign-off and client communication with the partner.

If you are weighing whether such a tool fits your practice, our earlier piece on what CA firms should compare before choosing an AI tax research tool sets out the questions to ask. And when a TDS default turns into a full scrutiny case, the steps in preparing a defensible response to an income tax scrutiny notice are a good next read.

Quick Quarter-End Checklist

A firm that runs this list every quarter will see fewer defaults, fewer late fees and far fewer anxious client calls.
