GST Refund for Inverted Duty Structure - citizen guide 2026

If your business buys inputs that are taxed at a higher GST rate than the rate you charge on your finished goods, your Input Tax Credit (ITC) keeps piling up and you can never fully use it. The law lets you claim this stuck money back. You file Form GST RFD-01 under clause (ii) of the proviso to Section 54(3) of the CGST Act, 2017, read with Rule 89(5), within two years of the relevant date. This is the inverted-duty-structure refund.

An inverted duty structure happens when the GST rate on the raw materials and goods you buy is higher than the GST rate on the product you sell. Because you pay more tax on inputs than you collect on output, your output tax is not enough to absorb all your input credit. The leftover ITC accumulates in your electronic credit ledger and stays unusable unless you claim it as a refund.

A plain example: a manufacturer buys plastic granules and chemicals taxed at 18 percent, and sells a finished product taxed at 5 percent. The 18 percent paid on inputs cannot be fully set off against the 5 percent collected on sales. Month after month, credit builds up. That accumulated credit is exactly what Section 54(3)(ii) lets you recover.

This is different from two other refunds people confuse it with. A refund of money sitting unused in your electronic cash ledger is a separate process, explained in our guide to the GST excess cash ledger refund. And a refund blocked because your supplier did not upload an invoice is an ITC-mismatch problem, not an inverted-duty claim.

The right to this refund comes from clause (ii) of the proviso to Section 54(3) of the Central Goods and Services Tax Act, 2017. It allows a refund of unutilised input tax credit where the credit has accumulated because the rate of tax on inputs is higher than the rate of tax on output supplies, other than nil-rated or fully exempt supplies.

The amount is computed under Rule 89(5) of the CGST Rules, 2017. The application is made in Form GST RFD-01 on the common portal, and the refund is processed by the jurisdictional GST officer. You must file within two years from the relevant date, as set out in Section 54(1).

1. Log in to the GST portal at gst.gov.in with your GSTIN and password.
2. Go to Services, then Refunds, then Application for Refund.
3. Select the refund type “Refund on account of ITC accumulated due to inverted tax structure”.
4. Choose the tax period (or range of periods) for which you are claiming the refund.
5. The portal opens the refund application. Enter your turnover figures so the system and your working can compute the Rule 89(5) amount.
6. Upload Statement 1 and Statement 1A, which capture the inverted-rated invoices and the maximum refund computation.
7. Give the declarations required under the provisos to Section 54(3), confirming the goods were not exported with payment of tax and that the supply is not nil-rated or exempt.
8. Set off the claimed amount against your electronic credit ledger when prompted, and submit with your DSC or EVC.
9. Note the ARN. Track the application under Services, then Refunds, then Track Application Status.

Rule 89(5) was amended with effect from 5 July 2022 (Notification No. 14/2022-Central Tax) and clarified by CBIC Circular 181/13/2022. The current formula is:

Maximum Refund Amount = {(Turnover of inverted rated supply of goods and services x Net ITC) / Adjusted Total Turnover} minus {Tax payable on such inverted rated supply of goods and services x (Net ITC / ITC availed on inputs and input services)}.

In plain terms, the first part works out how much of your total credit relates to your inverted sales. The second part subtracts the output tax you should have paid on those sales, scaled down in the same proportion in which you took credit on inputs and input services. This second leg is what the 2022 amendment changed, so businesses no longer lose out on the input-services portion the way they did under the old version.

What is excluded:

• Net ITC means ITC on input goods only. Credit on input services and on capital goods does not go into Net ITC, so that portion stays stuck and is not refundable here.
• Nil-rated and fully exempt outputs. If your output is nil-rated or exempt, there is no inverted-duty refund on it.
• Notified goods. The government has notified certain goods (for example some textile and construction items) where this refund is barred. Check the current notifications for your product before you file.

• Filing after two years. The portal may not stop you, but the officer will reject a claim filed beyond two years from the relevant date. The deadline is yours to track.
• Including input services or capital goods in Net ITC. Only input-goods credit qualifies. Padding the figure invites a deficiency memo.
• Claiming on exempt or nil-rated output. These are outside the scheme and will be disallowed.
• Wrong turnover figures. Mismatches between your Statement 1A, your GSTR returns and the portal data are the most common cause of partial or full rejection.
• Missing declarations or certificates. Incomplete Statement 1, Statement 1A or the required undertakings lead to a deficiency memo, after which you re-file fresh.
• Notified-goods bar. Filing for a product on the barred list gets rejected outright.

When my neighbour Dr. Shrawan Kumar Pathak helped a small fabric-trader friend file his first inverted-duty claim, the application bounced because input-services credit had been added into Net ITC. Once they stripped it down to input goods only and matched the turnover to GSTR-3B, the refund came through. The lesson stuck: keep Net ITC clean.

No. Under Rule 89(5), Net ITC covers ITC on input goods only. Credit on capital goods and on input services is excluded from the inverted-duty refund formula, so that portion cannot be recovered through this route.

You must file within two years from the relevant date under Section 54(1) of the CGST Act. The portal usually will not block a late filing, so it is your responsibility to apply on time.

No. The inverted-duty refund returns accumulated input tax credit caused by a higher input rate. A cash ledger refund returns money you actually paid into the electronic cash ledger but did not need. They use different categories in RFD-01.

Nil-rated and fully exempt output supplies do not qualify. Certain goods are also specifically notified by the government as barred from the inverted-duty refund, so confirm your product is eligible before filing.

First, confirm your input rate is genuinely higher than your output rate and that your product is not on the barred-goods list. Then reconcile your input-goods ITC with your GSTR filings, prepare Statement 1 and 1A, and file Form GST RFD-01 well inside the two-year window. If your problem is actually unused cash, use the cash ledger refund route instead. New to GST entirely? Start with how to apply for GST registration.
