Order of Utilisation: Sections 49A, 49B and Rule 88A

Order of Utilisation 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.

Three provisions govern how credit is applied against liability, and the interaction between them creates a genuine planning choice that most businesses never make deliberately.

Section 49(5) sets the basic order within each head. Section 49A overrides it: credit of integrated tax shall first be utilised towards payment of integrated tax, central tax, State tax or Union territory tax, and only after it has been fully utilised may credit of central tax, State tax or Union territory tax be used. Rule 88A: input tax credit on account of integrated tax shall first be utilised towards payment of integrated tax, and the amount remaining, if any, may be utilised towards the payment of central tax and State tax or Union territory tax, as the case may be, in any order.

The sequence

Step 1 — IGST credit against IGST liability. Mandatory first application.

Step 2 — remaining IGST credit against CGST and SGST or UTGST liability, in any order. This is the Rule 88A choice.

Step 3 — only after IGST credit is exhausted, CGST credit against CGST then IGST; SGST credit against SGST then IGST; UTGST credit against UTGST then IGST.

Never — CGST credit against SGST, or SGST credit against CGST. Section 49(5)(c) proviso and (d) proviso bar cross-utilisation between the two, absolutely.

The Rule 88A choice, and why it matters

Once IGST liability is discharged, the remaining IGST credit can go against CGST and SGST in any order — all to CGST, all to SGST, or any split.

The tax outcome is identical. The cash outcome is not.

Worked example. Liability: CGST ₹10 lakh, SGST ₹10 lakh. Credit: IGST ₹12 lakh, CGST ₹6 lakh, SGST ₹6 lakh.

Option A — IGST all to CGST:

• CGST: 12 (IGST) − 10 = IGST credit of ₹2 lakh remains; CGST liability nil, CGST credit ₹6 lakh unused.
• Remaining IGST ₹2 lakh to SGST; SGST 10 − 2 = ₹8 lakh, met from SGST credit ₹6 lakh; ₹2 lakh cash.
• Unused: CGST credit ₹6 lakh.

Option B — IGST split ₹6 lakh each:

• CGST: 6 (IGST) + 6 (CGST credit) = 12 against 10; ₹2 lakh CGST credit remains, no cash.
• SGST: 6 (IGST) + 6 (SGST credit) = 12 against 10; ₹2 lakh SGST credit remains, no cash.
• Total cash: nil.

Option B is ₹2 lakh better in the month. The difference arises because CGST credit cannot rescue an SGST shortfall, so an unbalanced allocation strands credit on one side.

The rule: apply IGST credit so as to leave the CGST and SGST positions balanced, not to exhaust one head first.

Section 49B and the notification power

Section 49B: notwithstanding anything contained in Chapter V or s.49(5), the Government may, on the Council's recommendation, prescribe the order and manner of utilisation of input tax credit.

Rule 88A is made under that power. The section is the enabling provision; the rule is the operative one.

Section 49(4): what the credit ledger cannot pay

Section 49(4): the amount available in the electronic credit ledger may be used for making any payment towards output tax.

Section 2(82) defines output tax as tax chargeable on taxable supplies made by the person or his agent, and excludes tax payable on reverse charge basis.

So the credit ledger cannot pay:

• reverse charge liability — cash only; ITC on reverse charge →
• interest;
• penalty;
• late fee;
• the pre-deposit for an appeal under s.107(6) — though the position on using credit for pre-deposit has been litigated, and several High Courts have permitted it for the tax component;
• tax under s.10 by a composition dealer, who has no credit at all.

All of these come from the electronic cash ledger.

Rule 86B: the 99% cap

A further restriction sits on top. Where the value of taxable supply, other than exempt supply and zero-rated supply, in a month exceeds ₹50 lakh, the registered person shall not use the credit ledger to discharge more than 99% of the output tax liability for that month.

With exceptions — including where the person or specified officers have paid income tax exceeding ₹1 lakh in each of the last two financial years, where the person received a refund exceeding ₹1 lakh on account of zero-rated supplies or inverted duty, where the person has discharged more than 1% of cumulative output tax liability in cash up to that month, or where the person is a Government department, PSU, local authority or statutory body. Rule 86B: the 99% restriction →

Key takeaways

• s.49A: IGST credit must be fully utilised first, before CGST or SGST credit.
• Rule 88A: after IGST liability, the balance may go to CGST and SGST in any order.
• Balance the CGST and SGST positions — an unbalanced allocation strands credit and forces cash.
• CGST and SGST credit can never be cross-utilised.
• The credit ledger pays output tax only — not RCM, interest, penalty or late fee.
• Rule 86B caps credit utilisation at 99% above ₹50 lakh monthly taxable supply, with exceptions.
