GST Refund — Inverted Duty Structure | Savlana Init

GST Compliance · Inverted Duty Refund

Inverted Duty Structure Refund — Higher Input Tax. Recovered.

When your input GST rate exceeds your output GST rate, ITC accumulates and cannot be used. Section 54(3) entitles you to a cash refund of the excess. We compute the Rule 89(5) refund, file RFD-01, and recover your blocked working capital.

An inverted duty structure (IDS) exists when the GST rate on inputs is higher than the GST rate on outputs — causing ITC to accumulate in the electronic credit ledger faster than it can be offset against output tax. The surplus ITC has no avenue for utilisation and permanently blocks the taxpayer's working capital. Section 54(3) of the CGST Act specifically addresses this situation, entitling the registered person to a refund of the net ITC accumulated due to the inverted rate structure.

The refund is computed under Rule 89(5) using the formula: Maximum Refund = (Net ITC × Inverted Rated Supply Turnover / Adjusted Total Turnover) − Tax Already Paid on Inverted Rated Supply. An important limitation — upheld by the Supreme Court in Union of India v. VKC Footsteps (2021) — is that only ITC on inputs (goods) is included in the Net ITC for this formula. ITC on input services is excluded from the IDS refund, significantly reducing the eligible refund for service-intensive businesses.

The IDS refund is particularly significant for industries where inputs attract 18% GST while outputs are taxed at 5% or 12% — such as fabric manufacturers (thread/yarn at 12%, fabric at 5%), fertiliser manufacturers (raw materials at 18%, fertiliser at 5%), and footwear manufacturers (below ₹1,000 MRP). We assess the genuine IDS in your supply chain, compute the correct refund under Rule 89(5), file RFD-01 for each eligible period, and pursue the refund to final sanction — freeing your blocked working capital on a regular basis.

Our Process

IDS Mapping & Quantum Assessment

Input and output GST rates are mapped and the Net ITC accumulation rate is confirmed — establishing the quantum of refund available each period.

Rule 89(5) refund is computed with inputs correctly ring-fenced from input services. Statement 1A and supporting ITC data are prepared.

RFD-01 Filing

Form GST RFD-01 is filed within the 2-year limitation period for each refund period — monthly or quarterly as preferred.

Deficiency Response

Any RFD-03 deficiency is replied to with correct computation evidence and legal submissions within the response window.

Sanction to Bank Credit

Each refund is tracked from provisional 90% sanction (RFD-04) through final sanction (RFD-06) to confirmed bank credit.

✓Multiple period applications filed — regular cash recovery schedule

✓Input service ITC correctly excluded after VKC Footsteps ruling

✓Statement 1A compiled accurately — no officer computation disputes

✓Deficiency memos replied to with correct supporting evidence

✓Final sanction tracked to bank credit each refund cycle

Frequently Asked Questions

An IDS exists when the GST rate on inputs exceeds the GST rate on outputs — causing ITC to accumulate without an offsetting output tax liability. Section 54(3) of the CGST Act permits a refund of this excess accumulated ITC, limited to ITC on inputs (goods) as per the Rule 89(5) formula.

No. The Supreme Court in Union of India v. VKC Footsteps India Pvt. Ltd. (2021) held that the Rule 89(5) formula does not permit inclusion of ITC on input services — only ITC on inputs (goods) is eligible. This is a firm legal position and cannot be overcome at the refund application stage — businesses with high input service ITC face a partial refund limitation.

Common IDS sectors include: textile manufacturers (thread/yarn at 12-18%, fabric at 5%); fertiliser manufacturers (raw materials at 18%, fertilisers at 5%); footwear manufacturers below ₹1,000 MRP; and certain solar equipment suppliers. The GST Council periodically reviews and corrects IDS situations through rate notifications.

For IDS refunds, the relevant date is the last date of the financial year in which the ITC was accumulated. For example, ITC accumulated during FY 2023-24 has a relevant date of March 31, 2024, giving a refund filing window until March 31, 2026.

A refund application can be filed for each tax period (monthly or quarterly) — allowing regular cash recovery. Quarterly filing is common as it reduces compliance effort while still releasing working capital on a timely basis. The refund applications can also be filed for multiple prior periods in a single batch, subject to the 2-year limitation.

If the Proper Officer rejects the refund in the final order (RFD-06), the taxpayer can appeal to the Commissioner (Appeals) under Section 107 within 3 months. The pre-deposit requirement for a refund rejection appeal is 10% of the disputed refund amount. Many IDS refunds wrongly rejected at the adjudication stage are overturned at the appellate forum.
