Most GST notices are self-inflicted. These are the seven mistakes we see most often — every one avoidable with a monthly discipline.

The usual suspects

  1. GSTR-1 vs 3B mismatch: sales detail says one thing, summary says another — the classic scrutiny trigger
  2. Claiming credit not in 2B: booking credit your supplier never reported
  3. Skipping nil returns: zero business does not mean zero filing
  4. Wrong tax head: paying IGST where CGST/SGST applied, or vice versa
  5. Ignoring reverse charge: transport, legal and import-of-service expenses with no matching RCM entries
  6. Unreconciled e-commerce data: platform reports differing from your GSTR-1
  7. Missing amendments: credit notes and corrections never reported in later returns

The fix is boring and it works

Reconcile three things before every filing: books vs GSTR-1, purchases vs 2B, and cash/credit ledgers vs liability. Twenty minutes monthly beats months of notice replies.
