Manner of Utilisation and Order of Set-off of ITC under GST

Updated 4 October 2026 · Fact-checked

Input tax credit sits in the electronic credit ledger as separate IGST, CGST and SGST balances. IGST credit pays IGST first, then CGST and SGST. CGST credit pays CGST, then IGST. SGST credit pays SGST, then IGST. CGST and SGST credits never pay each other. Interest, penalty and fees need cash.

Understand Manner of Utilisation and Order of Set-off of ITC

When you buy inputs and pay GST, the tax is credited to your electronic credit ledger. It is kept in three separate heads: IGST, CGST and SGST (or UTGST). The balance can only be used to pay output tax. It cannot be used to pay interest, penalty, late fee or any other dues. Those need cash from the electronic cash ledger.

The law fixes which credit can pay which tax. The rules are in Section 49 of the CGST Act, 2017 and Rule 88A of the CGST Rules. The idea is simple. IGST credit is the most flexible. CGST and SGST credits are tied to their own head first, and each can pay IGST only once the IGST credit has been used up.

The core rules: IGST credit must be used first to pay IGST, and only the balance may pay CGST and SGST, in any order. CGST credit pays CGST first, then IGST. SGST credit pays SGST first, then IGST. CGST credit can never pay SGST, and SGST credit can never pay CGST.

A further point: IGST credit must be used fully against the IGST liability first, and only the balance goes to CGST and SGST. CGST, SGST or UTGST credit can pay IGST only after the IGST credit has been completely used up, and only after it has met its own head. So you cannot keep IGST credit idle while paying IGST with CGST credit.

When IGST credit is left after paying IGST, the law lets you apply it to CGST and SGST in any order. It does not fix the head or the split. Applying it against the actual shortfall in CGST or SGST, that is, the liability left after that head's own credit is used, is only the way to minimise cash. It is a choice, not a legal requirement. Cash paid = total shortfall − IGST credit used against the shortfalls. So any split that stays within each head's shortfall gives the same cash. If you apply IGST credit to a head already covered by its own credit, that IGST credit is not used against a shortfall, and the shortfall in the other head has to be paid in cash. The law allows this, but it raises your cash outgo. If the leftover IGST credit is more than the total shortfall, cash is nil and the extra credit is carried forward. Questions often test this.

The ledger also has a dues order. Self-assessed tax and other dues of earlier tax periods are paid before those of the current period. Within each, tax comes before interest, penalty, fee and others.

Key rules to remember

IGST credit: IGST credit → IGST first → then CGST and SGST (any order); IGST credit must be fully used against IGST liability before CGST or SGST credit is used for IGST. The balance can pay CGST or SGST in any order.
CGST credit: CGST credit → CGST first → then IGST; CGST credit can never be used to pay SGST/UTGST.
SGST/UTGST credit: SGST/UTGST credit → SGST/UTGST first → then IGST; SGST credit can never be used to pay CGST.
Cash needed for each head: Cash payable = Output tax − credit that can lawfully be used against it (never below zero); Work head by head. Do not net total credit against total tax.
What credit can pay: Credit ledger → output tax only; Cash ledger → tax, interest, penalty, fee, other dues; Interest and late fee are always paid in cash.
Credit ledger restriction (Rule 86B): Where value of taxable supplies other than exempt supplies and zero-rated supplies exceeds ₹50 lakh in the month, credit ledger use ≤ 99% of output tax liability; at least 1% of output tax liability is paid through the electronic cash ledger; Rule 86B of the CGST Rules restricts use of the electronic credit ledger. In such a month, at least 1% of the output tax liability must be paid in cash, through the electronic cash ledger. The rule has exceptions. Read the exact text of Rule 86B for them. Apply the rule only if the question gives the facts. The worked examples below give no such facts, so the rule is not applied.

How to solve Manner of Utilisation and Order of Set-off of ITC questions

Use this method for any question that asks how much cash and how much credit is used to pay GST for a period.

1List the output tax liability separately as IGST, CGST and SGST. Note which heads have credit and which have none.
2List the opening credit balance in each head. Include any ITC reversed or blocked. Remove ineligible credit first.
3Use IGST credit against IGST liability first. Do this before touching CGST or SGST credit.
4If IGST credit is left, IGST liability is nil. The law lets you apply the leftover to CGST and SGST in any order. To pay the least cash, apply it against the shortfall left after each head's own credit, up to that shortfall. This is a choice to minimise cash, not a legal requirement. Give any balance to the other head.
5Use CGST credit against CGST liability, and SGST credit against SGST liability. Never cross them.
6If IGST liability remains after all IGST credit is used, pay it with the CGST and SGST credit left after their own heads are cleared, in any order. Leftover IGST credit exists only when IGST liability is nil, so this step and step 4 never apply together.
7Pay any remaining liability in cash, and pay interest, penalty and late fee in cash only.
8Write the closing credit balance for each head and the total cash paid. Show a small table in lines, head by head.

Quickest way: Head-by-head check for MCQs and written answers

When to use it: Use it when the question gives three tax heads with credit and liability figures and asks for cash payable or closing credit.

MCQ trick: if an option says CGST credit paid SGST or the reverse, eliminate it at once.
Write liabilities and credits in two rows of three columns: IGST, CGST, SGST.
Clear IGST liability with IGST credit. Then see where CGST and SGST are short after own credit, and give the leftover IGST credit to those shortfalls, up to the amount of each.
Compute cash for each head separately. Add up for total cash.
Written format: show the order of set-off in numbered lines, state the rule used (Section 49 and Rule 88A) in one line, and end with the cash paid and closing credit. Each correct line earns step marks.

Common mistakes in Manner of Utilisation and Order of Set-off of ITC

Using CGST credit to pay SGST liability, or SGST credit to pay CGST.
Students treat CGST and SGST as the same tax because the rates are equal.
Fix: They are separate heads, and the Act bars cross-use between them. Only IGST credit can pay both.
Netting total credit against total liability and calling the difference cash.
It feels natural to subtract one total from another.
Fix: Work head by head. Credit left in one head cannot always pay another head.
Paying interest or late fee out of the credit ledger.
Students think any balance in the ledger can pay any dues.
Fix: The credit ledger pays output tax only. Interest, penalty and fees are paid in cash.
Using CGST or SGST credit against IGST while IGST credit is still available.
Students forget the IGST-first condition.
Fix: Use IGST credit completely against IGST liability first. Only if IGST liability still remains may you pay it with CGST and SGST credit, in any order, after those credits have met their own heads.
Applying leftover IGST credit in a fixed order without checking cash.
Students memorise a fixed order and stop thinking.
Fix: The law allows leftover IGST credit to go to CGST or SGST in any order, so no order is mandatory. To minimise cash, put it against the head where your own credit is short, up to that shortfall. Treat this as a cash-saving choice, not a legal rule.
Forgetting to remove blocked or reversed credit before set-off.
Students start from the headline credit figure.
Fix: Take only eligible credit into the ledger. Adjust for reversals given in the question first.

Worked examples

Example 1

For a month, a registered person has output tax liability: IGST ₹50,000, CGST ₹40,000, SGST ₹40,000. Credit balance: IGST ₹70,000, CGST ₹30,000, SGST ₹25,000. Show the set-off so that cash payment is the least, and state the cash paid and closing credit.

Show the solution

IGST liability ₹50,000 is paid from IGST credit of ₹70,000. IGST credit left is ₹20,000. IGST liability is nil.
CGST liability ₹40,000 is first met from CGST credit ₹30,000, leaving a CGST shortfall of ₹10,000. SGST liability ₹40,000 is met from SGST credit ₹25,000, leaving an SGST shortfall of ₹15,000.
Apply the leftover IGST credit of ₹20,000 as ₹10,000 to CGST and ₹10,000 to SGST. CGST shortfall becomes ₹10,000 − ₹10,000 = nil. SGST shortfall becomes ₹15,000 − ₹10,000 = ₹5,000.
No IGST credit is left idle, so it is fully used against the shortfalls. Total shortfall ₹25,000 − IGST credit ₹20,000 = ₹5,000.
Cash: IGST nil, CGST nil, SGST ₹5,000. Closing credit is nil in all heads.

Answer: Cash payable is ₹5,000 (all SGST). Closing credit is nil in IGST, CGST and SGST.

Example 2

In an intra-state month, Mr A has output liability: CGST ₹60,000 and SGST ₹60,000, with no IGST liability. His credit balance: IGST nil, CGST ₹90,000, SGST ₹20,000. Compute cash payable and closing credit. Can the excess CGST credit pay the SGST?

Show the solution

CGST liability ₹60,000 is paid from CGST credit ₹90,000. CGST credit left is ₹30,000.
SGST liability ₹60,000 is paid first from SGST credit of ₹20,000. Balance ₹40,000 remains.
There is no IGST credit available, so no other credit can pay it. CGST credit cannot be used for SGST under Section 49.
The balance SGST ₹40,000 is paid in cash. The ₹30,000 CGST credit is carried forward.

Answer: Cash payable is ₹40,000 for SGST. Closing credit is CGST ₹30,000. CGST credit cannot pay SGST.

Exam tips

Draw the three-column layout of IGST, CGST and SGST first. It makes the answer clear and earns presentation marks.
State the rule in a line: IGST credit first for IGST, then CGST and SGST; CGST and SGST credits never cross. This is what examiners look for.
In MCQs, eliminate any option that uses CGST credit for SGST or the reverse, or uses credit ledger for interest.
If the question asks for the minimum cash, say that leftover IGST credit is applied to the head with the shortfall, and show it.
Check whether the question mentions blocked credit or reversals. Adjust the credit first, then set off.
