Net 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.
"Net ITC" is the credit figure that the GST refund formula shares out. The catch is that it does not mean the same thing in both formulas. For exports and SEZ supplies it includes input services; for inverted duty it does not. Capital goods are out of both. Get this line wrong and the claim is either cut or recovered later with interest.
Under Rule 89(4) (exports and SEZ under LUT or bond), Net ITC = ITC availed on inputs and input services during the relevant period. Under Rule 89(5) (inverted duty), Net ITC = ITC availed on inputs only; input services come in only through the ratio in the second bracket. Capital goods are excluded in both. Only credit actually availed in the period, and reflected in GSTR-2B, belongs in the figure.
The two definitions side by side
| Rule 89(4): zero-rated under LUT/bond | Rule 89(5): inverted duty | |
|---|---|---|
| Wording | "input tax credit availed on inputs and input services during the relevant period" | "input tax credit availed on inputs during the relevant period" |
| Inputs (goods) | Included | Included |
| Input services | Included | Excluded from Net ITC |
| Capital goods | Excluded | Excluded |
| Where input services still matter | In Net ITC itself | In the denominator of the ratio Net ITC ÷ ITC on inputs and input services |
"Inputs" under s.2(59) of the CGST Act are goods other than capital goods. So when the rule says "inputs" it means goods only, which is why services and capital goods fall outside the inverted-duty Net ITC.
The Supreme Court upheld this exclusion of input services in the inverted-duty formula in VKC Footsteps India, as the ICAI Refunds Handbook records. It is settled law, not a portal quirk.

What "availed during the relevant period" means in practice
- Availed means credit you have actually taken in GSTR-3B. Blocked credit under s.17(5) and credit you reversed never enters Net ITC.
- During the relevant period means the period of the claim. Credit taken in other periods belongs to those periods' claims.
- Reflected in GSTR-2B. Circular 135/05/2020-GST restricts refund to ITC reflected in GSTR-2A (now 2B). An invoice missing there is a common ground for a partial rejection; see refund rejected: ITC not in GSTR-2B.
- All tax heads together. The formula works on consolidated IGST + CGST + SGST/UTGST credit. Compensation cess, where still relevant, is worked out separately.
- All input rates. For inverted duty, the Handbook notes that Net ITC covers ITC on all inputs in the period, whatever their rate.
Example: one ITC register, two Net ITC figures (illustration)
A manufacturer's credit for a quarter, round figures:
| ITC availed in GSTR-3B | ₹ |
|---|---|
| Inputs (raw material, packing) | 6,00,000 |
| Input services (freight, job work, professional fees) | 2,00,000 |
| Capital goods (machinery) | 3,00,000 |
| Total credit in the ledger | 11,00,000 |
| Net ITC | |
|---|---|
| For a Rule 89(4) export claim | 6,00,000 + 2,00,000 = ₹8,00,000 |
| For a Rule 89(5) inverted-duty claim | ₹6,00,000 (inputs only) |
Scenario A: exporter under LUT
Zero-rated turnover ₹50,00,000; Adjusted Total Turnover ₹80,00,000.
Refund = 50,00,000 × 8,00,000 ÷ 80,00,000 = ₹5,00,000.
If capital-goods credit were wrongly added, Net ITC would be ₹11,00,000 and the formula would give 50,00,000 × 11,00,000 ÷ 80,00,000 = ₹6,87,500. The extra ₹1,87,500 is an erroneous refund that can be recovered with interest under s.73/74A. See erroneous refund recovery.
Scenario B: inverted-duty manufacturer
All output is inverted: turnover ₹80,00,000, ATT ₹80,00,000, output tax at 5% = ₹4,00,000.
- Bracket 1: 80,00,000 × 6,00,000 ÷ 80,00,000 = ₹6,00,000
- Bracket 2: 4,00,000 × (6,00,000 ÷ 8,00,000) = 4,00,000 × 0.75 = ₹3,00,000
- Maximum refund = 6,00,000 − 3,00,000 = ₹3,00,000
Input services do not add to the refund, but they do affect it: they sit in the denominator of the ratio in bracket 2, so they reduce how much output tax is deducted. Under the pre-July 2022 wording, the whole ₹4,00,000 would have been deducted, giving ₹2,00,000.
The 2022 amendment and its date
The ratio in bracket 2 came in through Notification 14/2022-CT (05.07.2022). Circular 181/13/2022-GST treated it as prospective, for applications filed on or after 05.07.2022. The Handbook records that the Gujarat High Court in Ascent Meditech Ltd. (17.10.2024) set aside that part of the circular and held the amendment clarificatory, so it applies to refund applications filed within the two-year limit. If an older claim was computed on the old wording, take advice on whether it can be revisited. Our inverted duty refund service reviews such claims.
Credit that never belongs in Net ITC
- ITC on capital goods, in both formulas.
- Input services, in the inverted-duty formula (they enter only the ratio).
- Blocked credit under s.17(5), since it is not availed.
- Credit not reflected in GSTR-2B.
- Credit of another period, unless you are claiming that period.
- For exporters: ITC where the third proviso to s.54(3) bars refund, such as where drawback of the same tax has been claimed. See duty drawback vs RoDTEP.
Need your ITC split checked before filing?
Splitting a year of purchase registers into inputs, input services and capital goods, then matching each line to GSTR-2B, is slow work and the place most refund cuts begin. We do the split, reconcile it and carry the right Net ITC into the statement. Try the GST refund calculator for a first figure, then contact us through the GST refund hub.
Key takeaways
- Rule 89(4) Net ITC = inputs + input services; Rule 89(5) Net ITC = inputs only.
- Capital goods are excluded from both.
- Input services still reduce the output-tax deduction in the inverted-duty formula.
- Only credit availed in the claim period and reflected in GSTR-2B counts.
- Over-stated Net ITC leads to recovery with interest, so split the register carefully.
