The 26AS vs GST turnover mismatch is one of the most common reconciliation issues before ITR filing. Main reasons and steps:
COMMON REASONS FOR MISMATCH:
- TDS UNDER SECTION 194-O: If you sell on e-commerce platforms (Amazon/Flipkart), TDS is deducted on gross sales. 26AS shows gross amount but your GST turnover may be net after sales returns.
- TIMING DIFFERENCES: Sale invoiced in March 2026 (in GSTR-1 for FY 2025-26) but TDS deducted and deposited in April 2026 appears in 26AS for FY 2026-27, not 2025-26.
- ADVANCES RECEIVED: GST liability arises on advance receipt; income recognition under IT act follows different rules. Advance in March for April work = GST FY 2025-26 but may be IT FY 2026-27.
- EXEMPT RECEIPTS: Interest, rental income below GST threshold, grants - these appear in 26AS but are not part of GST aggregate turnover.
- COMPOSITION TO REGULAR SWITCH: If you changed GST status mid-year, the calculation basis differs.
STEPS BEFORE JULY 31 FILING:
- Prepare a reconciliation statement categorising each difference (timing / exempt / 194-O / other)
- File ITR based on ACTUAL income with the reconciliation ready - do not inflate income merely to match 26AS
- If TDS in 26AS is higher than what the deductor should have deducted, file a request via TRACES for correction by the deductor (helps avoid future 143(1) intimation)
- For large unexplained gaps, consider an ITR extension and get books reconciled first - a defective return is worse than a late one
If the mismatch is purely timing, note the explanation in the ITR computation - AO can see this during scrutiny and a documented reconciliation protects you.
