The Law — Sec 49 → Sec 49A + Rule 88A
GST law doesn’t allow you to use ITC in any random order — a strict pecking order is prescribed. This was originally governed by Section 49, but was significantly tightened by the CGST Amendment Act 2018, which introduced Section 49A and the accompanying Rule 88A.
Old: Sec 49
→
ITC of IGST could be used against IGST → CGST → SGST/UTGST (any preference). This sometimes resulted in accumulation of CGST or SGST credit.
New: Sec 49A + Rule 88A
→
CGST Amendment Act 2018. ITC of IGST must be fully exhausted first before using ITC of CGST or SGST/UTGST. The “any preference” flexibility was removed.
Key Rule (Sec 49A): ITC of IGST shall be completely exhausted (used up) before using ITC of CGST or SGST/UTGST against any output liability.
Manner of Utilisation — The Set-Off Table
The table below shows which ITC can be used against which output tax liability — and in what order. The numbered circles (①②③…) match the order of utilisation as taught in the notes.
| ITC Available ↓ / Output Liability → | IGST Output | CGST Output | SGST / UTGST Output |
|---|---|---|---|
| ITC of IGST | ①First use | ②Second use (any pref.) | ②Second use (any pref.) |
| ③ Rule (Sec 49A): ITC of IGST shall be completely exhausted before using CGST / SGST ITC — पहले IGST का ITC पूरा Utilize करो | |||
| ITC of CGST | ⑤Allowed | ④First use | ✕Not Allowed |
| ITC of SGST / UTGST | ⑦Allowed | ✕Not Allowed | ⑥First use |
🚫 The Two Cross-Use Restrictions — Never Forget
- CGST ITC cannot be used to pay SGST/UTGST output liability
- SGST/UTGST ITC cannot be used to pay CGST output liability
- These two restrictions are absolute — no exceptions
- CGST and SGST are two separate government levies (Centre vs State) — hence cross-use is not permitted
The Rules — Simplified
📘 Rule 1 — IGST ITC: Most Flexible
ITC of IGST can be used to pay any output liability — IGST first (①), then CGST or SGST/UTGST in any order (②). It’s the most flexible ITC.
✅ Rule 2 — IGST Must Be Exhausted First
Before you can use CGST ITC or SGST ITC, the entire IGST ITC balance must be fully used up. Sec 49A / Rule 88A — no exceptions.
⚡ Rule 3 — CGST ITC: Centre Only
CGST ITC pays CGST output first (④), then IGST output (⑤). It cannot be used for SGST/UTGST — both belong to different governments.
⚡ Rule 4 — SGST/UTGST ITC: State Only
SGST/UTGST ITC pays SGST/UTGST output first (⑥), then IGST output (⑦). It cannot be used for CGST — strict Centre-State separation.
Worked Example — Step-by-Step
This is the exact numerical example from the Day 13 notes. Work through each step to see how ITC is applied in the correct order.
📋 Given Data
| IGST (₹) | CGST (₹) | SGST/UT (₹) | Total (₹) | |
|---|---|---|---|---|
| Output Tax Liability | 1,000 | 300 | 300 | 1,600 |
| Input Tax Credit (ITC) | 1,300 | 200 | 200 | 1,700 |
①
IGST ITC (1,300) → Pay IGST Output (1,000) first: Use ₹1,000 of IGST ITC to fully clear IGST output. Remaining IGST ITC = ₹300.
②
Remaining IGST ITC (300) → Pay CGST Output (300): Use the leftover ₹300 IGST ITC to pay CGST output liability. CGST output now cleared. Remaining IGST ITC = NIL.
③
Check Sec 49A: IGST ITC is now fully exhausted (NIL). ✅ We can now use CGST and SGST ITC.
④
CGST ITC (200) → Remaining CGST Output: CGST output was already cleared in step ②. But wait — the IGST ITC of ₹300 was used against CGST first. Let’s re-trace: After Step ①, IGST output = NIL, CGST output balance = 300. IGST ITC leftover = 300. Use ₹200 of that against CGST → CGST balance = 100. Then use remaining IGST ITC (100) against SGST output → SGST balance = 200.
⑤
CGST ITC (200) → Pay remaining CGST Output (100): Use ₹100 of CGST ITC → CGST Output = NIL. Remaining CGST ITC = ₹100 (carried forward C/F).
⑥
SGST ITC (200) → Pay SGST Output (200): Use ₹200 SGST ITC to fully clear SGST output. SGST Output = NIL. Remaining SGST ITC = NIL.
📊 Final Position
| Particulars | IGST (₹) | CGST (₹) | SGST/UT (₹) |
|---|---|---|---|
| Output Liability Remaining | Nil | Nil | Nil |
| ITC Balance C/F (Excess ITC) | — | 100 | — |
✅ All output liabilities fully paid. Excess CGST ITC of ₹100 carries forward to next month.
Quick-Recall Summary — Exam Ready
🎯 ITC Set-Off Order — Master Points
- Sec 49A (CGST Amend. Act 2018): ITC of IGST must be completely exhausted first before using CGST or SGST/UTGST ITC
- IGST ITC: Use against IGST (①), then freely against CGST or SGST (②) — most flexible
- CGST ITC: Use against CGST (④) first, then IGST (⑤) — NEVER against SGST
- SGST/UTGST ITC: Use against SGST/UTGST (⑥) first, then IGST (⑦) — NEVER against CGST
- Two absolute bars: CGST ↔ SGST/UTGST cross-utilisation is strictly prohibited
- Excess ITC: Unused ITC after clearing all output liabilities is carried forward (C/F) to the next tax period
- Old Sec 49 replaced by Sec 49A + Rule 88A to ensure IGST is always used first
💡 Why This Rule Exists
IGST is a central tax collected on inter-state supplies. By mandating that IGST ITC is used first, the government ensures that the IGST pool (which is shared between Centre and States) is utilised before touching the ring-fenced CGST (Centre only) and SGST (State only) pools. This avoids distortions in Centre-State revenue sharing.
