The ITC That Kept Piling Up: An Inverted Duty Structure Refund Lesson Under Section 54

A footwear manufacturer in Agra, run by two brothers, was doing everything by the book. They filed GSTR-1 and GSTR-3B on time, reconciled their credit every month, and never missed a due date. Yet their working capital was always tight. When their CA finally opened the electronic credit ledger, the reason was staring back at them: nearly Rs 9 lakh of unused input tax credit had simply accumulated over eighteen months, doing nothing.

The Problem: Higher Tax In, Lower Tax Out

The brothers bought raw materials such as synthetic soles, adhesives, chemicals and packaging that attracted GST at 18 percent. But the footwear they sold below a certain price point was taxed at a lower slab. Every month, the tax they paid on purchases was far more than the tax they collected on sales.

This is what GST law calls an inverted duty structure — where the rate of tax on inputs is higher than the rate on the output supply. The natural result is that ITC keeps building up faster than it can be used to pay output tax. The credit is genuine and fully eligible, but it stays stuck in the ledger.

The brothers had assumed this money was simply lost or would only adjust over many years. In reality, GST law allows a refund of this accumulated credit under Section 54 of the CGST Act, read with Rule 89(5) of the CGST Rules, through the specific route for refund on account of inverted duty structure.

What They Were Getting Wrong

Their first mistake was treating accumulated ITC as unavoidable. The second was not knowing that the refund covers credit on inputs (goods), not input services or capital goods, when claimed under the inverted structure formula. They had also been mixing up their trading and manufacturing figures, which muddied the calculation.

How They Fixed It Correctly

Working with their CA, they took a clean, step-by-step approach.

Step 1 — Confirmed eligibility. They verified that their output was genuinely taxed lower than their major inputs, and that the goods were not on the list of items where the government has restricted inverted refunds through notification.

Step 2 — Applied the correct formula. Rule 89(5) prescribes a formula that computes the maximum refund based on turnover of inverted-rated supply, net ITC, and adjusted total turnover. They fed accurate figures rather than the full ledger balance, so their claim matched the law.

Step 3 — Filed Form RFD-01 online, tax period by tax period. They filed within the time limit — refund applications must generally be made within two years from the relevant date, so they cleared the older periods first before the window closed.

Step 4 — Kept documents ready. Purchase invoices, a statement of inward and outward supplies, and the computation sheet were organised so that when the officer sought clarification, they responded quickly instead of letting the claim lapse.

Within a few filing cycles, a large part of that stuck credit came back as cash into their bank account.

The Key Lesson for Readers

Accumulated ITC is not dead money. If your inputs are taxed higher than your finished goods — common in footwear, textiles, fertilisers, LED products and several fabricated items — you may be sitting on a refund you never claimed. The two things that quietly kill these claims are the two-year time limit and wrong computation under Rule 89(5). Review your credit ledger every quarter, not once a year.

Also remember: the inverted refund is for inputs. Credit on input services and capital goods generally stays in the ledger to be used against future liability.

How GSTClear Helps

GSTClear flags when your input tax rate consistently exceeds your output rate and highlights growing credit balances before they turn into a working-capital problem. It helps you compute the Rule 89(5) refund correctly, tracks the two-year deadline for each tax period, and keeps your purchase and supply statements refund-ready so RFD-01 filing is smooth. Instead of discovering stuck lakhs eighteen months late, you see the opportunity in real time.

If your electronic credit ledger keeps growing month after month, do not let that money sit idle. Check your inverted duty position with GSTClear today and turn unused credit back into cash.
