Utilisation of ITC and Order of Set-off under Section 49A

Updated 11 October 2026 · Fact-checked

Utilisation of ITC means using the balance in your electronic credit ledger to pay output tax. Section 49A requires IGST credit to be used up fully first. Then CGST and SGST/UTGST credit is used, and section 49(5) fixes which credit pays which tax. CGST credit can never pay SGST/UTGST, and the reverse.

Understand Utilisation of ITC and Order of Set-off under Section 49A

Every registered person has two ledgers. The electronic cash ledger holds money you deposit (net banking, cards, NEFT, RTGS). The electronic credit ledger holds input tax credit (ITC) that you self-assess in your return. Section 49(3) lets cash pay tax, interest, penalty, fees and any other amount. Section 49(4) lets credit pay only output tax, under the CGST Act or the IGST Act.

So credit cannot pay interest, penalty or fee. Those must be paid in cash. This is a common exam point.

Credit sits in separate heads: IGST, CGST, SGST (or UTGST) and cess. Section 49(5) says which head can pay which liability. IGST credit pays IGST first, then CGST, then SGST/UTGST, in that order. CGST credit pays CGST first, then IGST. SGST or UTGST credit pays SGST or UTGST first, then IGST. CGST credit cannot pay SGST/UTGST, and SGST/UTGST credit cannot pay CGST.

Section 49A adds a priority rule that overrides section 49. CGST, SGST or UTGST credit can be used towards any tax only after IGST credit has first been used fully towards that payment. In practice, you exhaust IGST credit before touching CGST or SGST credit.

There is one more rule inside section 49(5). SGST or UTGST credit can pay IGST only where the balance of CGST credit is not available for paying IGST. So when IGST remains payable, CGST credit goes first, then SGST/UTGST credit.

Key rules to remember

Credit pays output tax only
Electronic credit ledger → output tax (CGST Act or IGST Act)
Section 49(4). Interest, penalty and fee need cash under section 49(3).
IGST credit order
IGST credit → IGST, then CGST, then SGST/UTGST
Section 49(5)(a). The order is fixed.
CGST credit order
CGST credit → CGST, then IGST
Section 49(5)(b). Never SGST/UTGST (section 49(5)(e)).
SGST/UTGST credit order
SGST/UTGST credit → SGST/UTGST, then IGST
Section 49(5)(c),(d). Never CGST (section 49(5)(f)). IGST only if CGST credit balance is not available for IGST.
Section 49A priority
Use IGST credit fully first, then CGST/SGST/UTGST credit
Applies to payment of any tax head, notwithstanding section 49.
Order of discharge of dues
(a) self-assessed tax and dues of earlier periods; (b) current period self-assessed tax and dues; (c) other amounts, including demands under section 73, 74 or 74A
Section 49(8).
Cap on credit use
Government may specify a maximum proportion of output tax payable through the credit ledger
Section 49(12), on Council recommendation. Check the notified limit in the question.

How to solve Utilisation of ITC and Order of Set-off under Section 49A questions

Use this method for any set-off question. Keep each tax head separate throughout.

  1. 1List the output liability under each head: IGST, CGST, SGST/UTGST. Note any interest or penalty, which needs cash.
  2. 2List the credit balance under each head from the electronic credit ledger.
  3. 3Apply IGST credit first (section 49A): against IGST, then CGST, then SGST/UTGST, in that order.
  4. 4If IGST credit is exhausted, use CGST credit against CGST liability, then against any IGST balance.
  5. 5Use SGST/UTGST credit against SGST/UTGST liability, then against any IGST balance left after CGST credit is used.
  6. 6Never set CGST credit against SGST/UTGST or SGST/UTGST credit against CGST.
  7. 7Pay the remaining liability, and interest, penalty and fee, from the electronic cash ledger.
  8. 8State the closing balance of each credit head and the cash paid, then give the conclusion.

Quickest way: Head-wise table drill

When to use it: Use this when the question gives output and credit figures for all three heads and asks for the cash payable.

  1. Write the three liabilities and three credit balances side by side.
  2. Wipe out IGST liability with IGST credit. Use leftover IGST credit on CGST, then SGST.
  3. Match remaining CGST credit to CGST liability, SGST credit to SGST liability.
  4. Use any surplus CGST credit, then SGST credit, for IGST liability that is still unpaid.
  5. Cash payable equals liability left under each head. Check that no CGST credit went to SGST.

Common mistakes in Utilisation of ITC and Order of Set-off under Section 49A

  • Using CGST credit to pay SGST liability, or the reverse.

    Students treat CGST and SGST as one pool because rates are equal.

    Fix: Remember section 49(5)(e) and (f): cross-use is barred. Only IGST credit moves across to both.

  • Using CGST credit before IGST credit is used up.

    Students follow the head-wise order and forget section 49A.

    Fix: Always start with IGST credit and exhaust it before using any CGST or SGST credit.

  • Paying interest or penalty from the credit ledger.

    Students think any ledger balance can pay any amount.

    Fix: Credit pays only output tax (section 49(4)). Interest, penalty and fee go through the cash ledger.

  • Applying IGST credit to SGST before CGST.

    Students pick the head with the larger liability.

    Fix: Section 49(5)(a) fixes the order: IGST, then CGST, then SGST/UTGST.

  • Using SGST credit for IGST while CGST credit is still available.

    Students miss the proviso to section 49(5).

    Fix: For IGST liability, use CGST credit first. Use SGST/UTGST credit only when CGST credit balance is not available.

  • Skipping the discharge order for dues.

    Students pay the current period first.

    Fix: Under section 49(8), clear earlier-period self-assessed tax and dues first, then the current period, then other amounts such as demands.

Worked examples

Example 1

Rohan Traders, Pune, has output liability of IGST ₹40,000, CGST ₹90,000 and SGST ₹90,000. Credit balance: IGST ₹70,000, CGST ₹30,000, SGST ₹50,000. Compute the cash payable. Ignore any cap on credit use.

Show the solution
  1. Section 49A: use IGST credit first. Against IGST liability: ₹40,000. IGST liability becomes nil. IGST credit left: ₹30,000.
  2. Section 49(5)(a): remaining IGST credit goes to CGST next. ₹30,000 against CGST ₹90,000. CGST liability left: ₹60,000. IGST credit left: nil.
  3. Use CGST credit ₹30,000 against the remaining CGST ₹60,000. CGST liability left: ₹30,000. CGST credit left: nil.
  4. Use SGST credit ₹50,000 against SGST ₹90,000. SGST liability left: ₹40,000. SGST credit left: nil.
  5. Cash payable: CGST ₹30,000 + SGST ₹40,000 = ₹70,000.

Answer: Cash payable is ₹70,000 (CGST ₹30,000 and SGST ₹40,000). All credit is used up.

Example 2

Meera Exports Ltd., Chennai, has output liability of IGST ₹1,00,000 and CGST ₹20,000. Credit balance: IGST ₹30,000, CGST ₹60,000, SGST ₹50,000. Interest of ₹5,000 is also payable. How is the liability discharged? Ignore any cap on credit use.

Show the solution
  1. Section 49A: use IGST credit ₹30,000 against IGST ₹1,00,000. IGST liability left: ₹70,000.
  2. Use CGST credit against CGST liability ₹20,000 first (section 49(5)(b)). CGST liability becomes nil. CGST credit left: ₹40,000.
  3. Use the remaining CGST credit ₹40,000 against IGST ₹70,000. IGST liability left: ₹30,000. CGST credit left: nil.
  4. Now CGST credit is not available for IGST. Under the proviso to section 49(5), SGST credit ₹30,000 can pay the IGST ₹30,000. SGST credit left: ₹20,000.
  5. IGST liability is nil. Interest ₹5,000 cannot be paid from credit (section 49(4)). It is paid from the electronic cash ledger.

Answer: Output tax is fully paid from credit. Cash payable is ₹5,000 (interest only). Closing credit: SGST ₹20,000. IGST and CGST credit are nil.

Exam tips

  • Draw a small table of liability and credit by head. Examiners give marks for showing the order step by step.
  • Quote section 49A for the IGST-first rule and section 49(5) for the cross-head rules. Do this in the provision part of your answer.
  • Always state that interest, penalty and fee need cash. Many case questions test this.
  • If the question mentions a cap on credit use, apply it as notified under section 49(12). Do not assume a limit that is not given.
  • End with a one-line conclusion: cash paid and closing credit under each head.

Utilisation of ITC and Order of Set-off under Section 49A: frequently asked questions

What does Section 49A of the CGST Act say?

It says that CGST, SGST or UTGST credit can be used to pay any tax only after IGST credit has first been fully used for that payment. It applies notwithstanding section 49. In short, exhaust IGST credit first.

Can CGST credit be used to pay SGST?

No. Section 49(5)(e) bars CGST credit from paying SGST or UTGST. Section 49(5)(f) bars SGST or UTGST credit from paying CGST. Only IGST credit can pay all three taxes.

Can ITC be used to pay interest or penalty?

No. Under section 49(4), the electronic credit ledger can pay only output tax. Interest, penalty, fees and other amounts are paid from the electronic cash ledger under section 49(3).

What is the difference between the electronic cash ledger and the credit ledger?

The cash ledger holds money you deposit and can pay tax, interest, penalty, fees and other amounts. The credit ledger holds ITC and can pay only output tax. Balances in either can be refunded as per section 54.
