Return-processing season is when many small business owners open an intimation and see a demand they do not owe. The usual cause is a wrong or missing entry in Form 26AS or the Annual Information Statement (AIS). The fix is a fixed sequence of steps; here it is.

Key takeaway: If TDS is missing, the deductor must file a correction to its TDS return — you cannot fix it yourself. If AIS shows income that is not yours, mark it through AIS feedback. Once records are right, file a rectification request or respond to the demand on the e-filing portal. Do not ignore it: unpaid demands can be adjusted against refunds.

The 5 most common wrong entries

Fix it in five steps

  1. Download Form 26AS and AIS from the e-filing portal and compare them with your books and the intimation.
  2. Give AIS feedback on each wrong item: Information is not fully correct, Duplicate, Not applicable, or belongs to another PAN. Keep proof.
  3. Ask the deductor (your customer, bank or platform) in writing to file a correction statement with the right PAN and amount. Ask for the revised TDS certificate (Form 16A).
  4. Check 26AS again after a few weeks. When the credit appears, file a rectification request under Section 154 on the portal so the demand is recalculated.
  5. Respond to the demand under Pending Actions → Response to Outstanding Demand: choose that you disagree, select the reason (for example TDS credit mismatch), and upload proof.

These return-processing steps apply to FY 2025-26 and earlier, which are still governed by the Income-tax Act, 1961, even though the new Income-tax Act, 2025 applies from tax year 2026-27.

Example

A contractor bills a company ₹5,00,000. The company deducts 2% TDS (₹10,000) under Section 194C and pays ₹4,90,000, but quotes a wrong PAN. The contractor claims ₹10,000 TDS in the return; 26AS shows nil, so the intimation raises a demand of ₹10,000 plus interest. Once the company corrects the PAN, the credit shows in 26AS, and a Section 154 rectification removes the demand.

Before you respond: pitfalls

Spot missing TDS early in DAM

Steps use DAM's Reports dashboard and in-app search.

  1. Open Search and type Reports, then open Party Statement for a customer who deducts TDS.
  2. Compare invoice totals with what they actually paid: the gap should equal the TDS deducted.
  3. Match that TDS against Form 26AS each quarter, and chase the customer early if it is missing.

Match every customer payment to its invoice

See what each party billed, paid and still owes — so missing TDS is easy to spot.
