You have a Form 16A from your client showing Rs. 42,000 of TDS. Your Form 26AS shows Rs. 28,000. Or shows nothing at all. Two documents about the same deductions, from the same client, disagreeing — and filing season is closing.
Almost every version of this mismatch is diagnosable in about two minutes, and the first thing to check is not the numbers. It is whether the document you are holding is a Form 16A at all.
What each document actually is
| Form 16A | Form 26AS | |
|---|---|---|
| Issued by | Your client, the deductor | The Income Tax Department |
| Under | Rule 31(1)(b) of the Income Tax Rules, 1962 | Section 285BB read with Rule 114-I of the Income Tax Rules, 1962 |
| Covers | One deductor, one quarter | Every deductor, every quarter, whole year |
| You get it | From the client, quarterly | From the e-filing portal, any time |
What that table hides is the thing that matters: both documents are generated from the same underlying event — the quarterly statement your client files. Form 26AS is assembled from it. And a valid Form 16A is generated from it too.
First check: is that actually a Form 16A?
A deductor cannot simply prepare a TDS certificate for non-salary payments. Form 16A must be generated and downloaded from TRACES, the department’s own system, and it carries a unique certificate number for that reason.
This is not a convention — it is mandated, and the mandate tightened over three circulars. CBDT Circular 03/2011 required companies and banks to issue Form 16A from the central system. Circular 01/2012 extended that to all deductors. Circular 04/2013 then settled the point that matters here: only a certificate downloaded from TRACES is a valid TDS certificate.
TRACES can only generate a certificate for a deduction that has been filed. So a genuine Form 16A cannot exist for a deduction that is not in the department’s records.
That single fact resolves the most common version of this mismatch. If you are holding a "Form 16A" that is a Word document, an unsigned PDF on the client’s letterhead, or a spreadsheet from their accountant — and 26AS shows nothing — you do not have two conflicting records. You have one record (26AS, which is empty) and a letter.
If it is genuine, there are four ways they can disagree
1. You are comparing different periods
Form 16A is quarterly. Form 26AS is annual. Four certificates should sum to the year, and it is remarkably easy to hold three of them and conclude the statement is over-reporting. Check the quarter on each certificate before comparing anything.
The related trap is timing. A quarter’s deductions only appear in 26AS once the client files the statement for it — 31 July for April-June, 31 October for July-September, 31 January for October-December, and 31 May for January-March. A Q4 certificate in hand while 26AS is still blank for Q4 is normal until well into June.
2. The certificate is stale
Certificates are generated at a point in time. If the client later filed a correction — fixing a wrong PAN, a wrong section, a wrong amount — then 26AS reflects the correction and your certificate reflects what was true before it. 26AS is the current record. Ask the client to re-download the certificate from TRACES rather than assuming either document is wrong.
3. The amounts genuinely differ
Where the certificate says more than the statement, the usual cause is a partly-filed quarter or a deduction reported against a different PAN. Where the statement says more, look for a second engagement with the same client you have forgotten, or a deduction from a related entity with a similar name.
4. The section differs
The certificate says 194J and the statement says 194C, or the reverse. Your credit is not affected by this — it follows the amount reported, not the label — but the label has consequences for your client and sometimes for your cashflow.
When they disagree, which one do you file on?
Form 26AS. Without exception, and it is not a judgement call.
Credit for TDS is given under Section 199 of the Income-tax Act, 1961 read with Rule 37BA of the Income Tax Rules, 1962, and the mechanism there is that credit follows the deductor’s statement. Form 26AS is that statement, aggregated. A certificate showing more than the statement does not entitle you to claim more; claiming the certificate figure creates a mismatch and, quite often, a defect notice.
Settling it against your own records
Neither document knows what you invoiced. The only way to tell a stale certificate from a genuinely missing deduction is to put both next to your own invoice list and see which clients matched, which are merely pending on the filing calendar, and which have nothing behind them at all.
