Quick Recap & Core Concepts: ITC Set Off

Input GST: Purchase ke time par suppliers ko pay kiya gaya tax (Business Asset / Credit).

Output GST: Sales ke time par customers se collect kiya gaya tax (Business Liability).

Core Formula:
Net GST Payable = Output GST Liability − Eligible Input Tax Credit (ITC)

Statutory GST Set Off & Cross-Utilization Rules

IGST Credit Utilization Priority:

• 1st: Set off against IGST Liability
• 2nd: Set off against CGST Liability
• 3rd: Set off against SGST Liability

CGST Credit Utilization Priority:

• 1st: Set off against CGST Liability
• 2nd: Set off against IGST Liability
• Restriction: CGST credit cannot be used to pay SGST.

SGST Credit Utilization Priority:

• 1st: Set off against SGST Liability
• 2nd: Set off against IGST Liability
• Restriction: SGST credit cannot be used to pay CGST.

Absolute Golden Rule:
CGST ITC ≠ SGST Liability
SGST ITC ≠ CGST Liability
CGST aur SGST credits aapas mein cross-utilize nahi ho sakte.

Master Setup & Company Details

Company Details

• Company: ABC Traders (Maharashtra) | Registration: Regular | FY: 2026–27

Required Tax Ledgers (Under Duties & Taxes → GST):

Practical Scenarios & Set Off Walkthroughs

Scenario 1: Local Purchase + Local Sale

• 01-Apr (Purchase F9): Purchased goods ₹1,00,000 @ 18% GST → Input CGST = ₹9,000, Input SGST = ₹9,000 (Total ₹1,18,000).
• 01-Apr (Sales F8): Sold goods ₹2,00,000 @ 18% GST → Output CGST = ₹18,000, Output SGST = ₹18,000 (Total ₹2,36,000).
• Set Off:
  • CGST Payable: ₹18,000 − ₹9,000 = ₹9,000
  • SGST Payable: ₹18,000 − ₹9,000 = ₹9,000
  • Total Net Cash Payable = ₹18,000

Scenario 2: Interstate Purchase + Local Sale (Cross-Utilization)

• Purchase: ₹5,00,000 from Gujarat Supplier → Input IGST = ₹90,000.
• Sales: ₹6,00,000 to Maharashtra Customer → Output CGST = ₹54,000, Output SGST = ₹54,000.
• Set Off Order:
  1. IGST Credit (₹90,000) used against CGST Liability (₹54,000) → CGST Payable becomes Nil.
  2. Remaining IGST Credit (₹36,000) used against SGST Liability (₹54,000).
  3. SGST Payable = ₹54,000 − ₹36,000 = ₹18,000.

Scenario 2 Settlement Summary:

Scenario 3: Full Monthly Settlement Simulation

Purchases: Local ₹3,00,000 (CGST ₹27,000 + SGST ₹27,000) | Interstate ₹2,00,000 (IGST ₹36,000).

Sales: Local ₹8,00,000 (CGST ₹72,000 + SGST ₹72,000) | Interstate ₹5,00,000 (IGST ₹90,000).

Verification Reports, Common Mistakes & FAQs

Reports to Verify in TallyPrime:

• GST Computation: Real-time overview of gross output liability, available input credit, and net payable.
• GSTR-3B: Reconcile eligible ITC allocation and tax payment schedules.
• Duties & Taxes Ledgers: Verify that input tax balances are reduced by the set-off amounts.

Common Mistakes:

• Attempting to set off CGST credit against SGST liability (prohibited by GST law).
• Passing manual, unlinked Journal entries instead of using the statutory set-off workflow in GSTR-3B.
