5 common GST filing mistakes small shops make

Most penalty notices we see in our Tally classes trace back to a handful of repeated mistakes, not complicated tax law.

Late filing is the most common — even a one-day delay can trigger a late fee. Setting a recurring reminder a week before the due date avoids this entirely.

Mismatched invoice details between your books and your supplier's filing is another frequent issue. Reconciling monthly, rather than at year-end, catches errors early.

Incorrect HSN codes, missing e-way bills for larger shipments, and claiming input tax credit without proper documentation round out the list. Our GST module spends extra time on exactly these four areas.
