Refund of ITC explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Exporters who have just bought machinery, laptops or plant often see a large credit balance and assume it can be refunded along with other export credit. Under the LUT route it cannot. The refund formula counts credit on inputs and input services only. There are still lawful ways to turn that credit into cash, and one clear mistake to avoid.
The Rule 89(4) formula refunds "Net ITC", defined as ITC availed on inputs and input services during the relevant period. ITC on capital goods is excluded, and the ICAI Refunds Handbook says so directly. An exporter can still use capital goods credit to pay IGST on exports and get that IGST refunded under Rule 96 (goods) or Rule 96(9) (services), or set it off against domestic output tax. If capital goods credit was wrongly included in an LUT refund, it must be repaid with interest; Circular 174/06/2022-GST provides for re-credit on voluntary repayment.
Why capital goods credit is outside the refund formula
Section 54(3) allows refund of unutilised ITC on zero-rated supplies made without payment of tax. How much is refundable is set by Rule 89(4):
Refund = Turnover of zero-rated supply × Net ITC ÷ Adjusted Total Turnover
"Net ITC" is credit on inputs and input services. The same design applies to inverted-duty refunds, where the Handbook notes that "inputs" do not include services or capital goods. Answering the direct question in its FAQ section, the Refunds Handbook states that ITC on capital goods is explicitly excluded and is not eligible for refund under the zero-rated formula.
| Credit type | Enters Net ITC for the LUT refund? | Other use |
|---|---|---|
| Inputs (raw material, packing, consumables) | Yes | — |
| Input services (freight, rent, professional fees, cloud) | Yes | — |
| Capital goods (machinery, computers, tools) | No | Pay IGST on exports or domestic output tax |
| Blocked credit under section 17(5) | No | Not available at all |

Worked illustration: the LUT route
A manufacturer's quarter looks like this (round figures for illustration):
- export turnover (lower of FOB and invoice value): ₹1.2 crore;
- domestic turnover: ₹30 lakh;
- ITC on inputs and input services: ₹12 lakh;
- ITC on a new machine bought this quarter: ₹9 lakh;
- domestic output tax paid from the ledger: ₹4 lakh.
Refund = 120 × 12 ÷ 150 = ₹9.6 lakh.
The ₹9 lakh on the machine does not enter the formula. It stays in the ledger and gets used against domestic output tax over time. With domestic output of only ₹4 lakh a quarter, the credit can take several quarters to absorb. That is the practical problem for export-heavy businesses.
The IGST route: how capital goods credit gets used
Where exports are made on payment of IGST, the tax is paid from the electronic credit ledger, and capital goods credit can be used for it like any other credit. The IGST is then refunded: for goods, through the shipping bill under Rule 96; for services, through RFD-01 under Rule 96(9). The Refunds Handbook lists this as an advantage of the IGST route: exporters can encash ITC, including credit accumulated on capital goods, that might not otherwise be refundable.
Same illustration on the IGST route. Assume an 18% rate for illustration. IGST on exports of ₹1.2 crore = ₹21.6 lakh. Assume the domestic output tax is paid in cash, so the ledger still holds ₹12 lakh (inputs) + ₹9 lakh (capital goods) = ₹21 lakh. The exporter pays ₹21 lakh from the ledger and ₹0.6 lakh in cash, and Customs refunds the full ₹21.6 lakh. The machine credit is now cash.
| LUT route | IGST route | |
|---|---|---|
| Refund in this quarter | ₹9.6 lakh | ₹21.6 lakh |
| Capital goods credit | Stays in the ledger | Used and refunded |
| Tax paid up front | None | ₹21.6 lakh, via ledger and cash |
| Risk if the claim fails | Deficiency memo or rejection | Rejected ITC is not re-credited automatically |
Limits on switching to the IGST route
- Restricted goods. Section 16(4) of the IGST Act lets the Government notify which exports may be made on payment of IGST. Notification 01/2023-Integrated Tax allows all goods and services except the goods listed in its table. Check your HSN before switching.
- Data discipline. The IGST refund on goods only flows when GSTR-1 Table 6A, GSTR-3B Table 3.1(b), the shipping bill and the export manifest agree. See IGST refund not received: Table 6A mismatch.
- Old Rule 96(10). This restriction on the IGST route for exporters receiving concessional or deemed-export supplies was omitted from 08.10.2024.
- Choose per invoice, not both. The third proviso to section 54(3) bars an ITC refund on supplies where IGST refund is claimed.
If capital goods credit went into an LUT claim
This is a common audit point. The Refunds Handbook's position is that the excess refund has to be repaid with interest and any penalty. After the 47th GST Council meeting, Circular 174/06/2022-GST set up a re-credit mechanism: where the amount is voluntarily repaid, the corresponding credit can be restored to the electronic credit ledger. Correct it before the department raises it; see erroneous refund recovery and re-credit through PMT-03.
Need help recovering capital goods credit?
If machinery credit is locked up because your output is mostly exports, the choice between routes needs to be made with real numbers. We model both, check whether your products can go on the IGST route and file the claims. See our export refund under LUT service, or IGST refund support if you move to the payment route.
Key takeaways

- The IGST route lets you pay export tax with capital goods credit and get it refunded.
- Check Notification 01/2023-Integrated Tax before switching routes.
- A wrong claim must be repaid with interest; Circular 174/06/2022-GST allows re-credit on voluntary repayment.
