How a Bhavnagar Ceramics Exporter Sorted Three Years of GST Filing in One Quarter

TL;DR

A Bhavnagar-area ceramics and tiles exporter had input tax credit blocked across multiple years of GST returns because GSTR-1 filings did not match GSTR-3B claims. The gap was not fraud — it was three years of hurried monthly filings with no reconciliation. A structured quarterly process sorted it, unlocked the credits, and made the monthly cycle faster going forward.

Ceramics and tiles businesses in Gujarat — especially those sourcing from Morbi or exporting finished goods — deal with a complex GST situation almost by default. Multiple suppliers, mixed rates, and export-oriented supply chains that involve IGST claims, LUT filings, and refund cycles. It is not a sector where you can file GSTR-1 and GSTR-3B from memory and move on.

What the Business Was Facing

The business had been filing GST returns monthly for three years. Invoices were uploaded to GSTR-1; the summary return GSTR-3B was filed; and that was the end of it. Nobody went back to check whether the figures in GSTR-1 actually matched the claims in GSTR-3B.

The first time the books were pulled apart for a formal reconciliation, the numbers did not line up in three ways:

One — missing invoices in GSTR-1. Several purchase invoices from the previous year had been uploaded to GSTR-3B as ITC claims but had never been uploaded to GSTR-1 by the supplier. Under GST law, an ITC claim requires the supplier to have filed that invoice in their GSTR-1.

Two — HSN rate mismatches. Some input materials were purchased at 12% GST but the output supplies were filed at a different classification. Without reconciliation, nobody had noticed the systematic overspend on taxes paid.

Three — export invoices missing LUT reference. Export supplies filed under LUT did not have the LUT reference consistently entered in the GSTR-1 shipping bill details.

The Process

The first step was a full import of all GSTR-2A and GSTR-2B data. Once the two-year GSTR-2B history was in a spreadsheet, the reconciliation identified three categories of gaps: supplier not filed, rate mismatch, and missing export LUT references.

After the gaps were addressed and the amended returns filed for the affected periods, the business was in a position to claim the input tax credit that had been sitting unrealised. More importantly, the monthly filing process was rebuilt to include a reconciliation step.

What Any Gujarat Business in the Same Situation Can Check Today

Download GSTR-2B for the last two tax periods and compare it against your purchase register. If any invoice in your books is not showing up in GSTR-2B, the ITC claim is not going through — and the reason is usually that the supplier either did not file or filed it under a different invoice number.

For manufacturers or traders dealing with mixed HSN codes, the rate classification on the purchase invoice must match the actual HSN of the material. A mismatch means the credit is either blocked or must be reversed.
