Goods and Services Tax (GST) Architecture, Input Tax Credit (ITC) & GST Audit Manual under BNSS 2023

1. Executive Summary & Consolidated Indirect Tax Framework

The implementation of the Goods and Services Tax (GST) under the CGST Act, SGST Acts, and IGST Act, 2017 consolidated multiple indirect levies (service tax, VAT, excise, central sales tax) into a unified destination-based tax structure. Governed by the GST Council and enforced by central/state GST commissionerates, compliance relies on real-time portal invoicing and Automated Return Matching.

With the establishment of the GST Appellate Tribunal (GSTAT) and enhanced criminal prosecution under the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, GST non-compliance, fake invoicing claims, and input tax credit fraud face strict statutory audits and judicial proceedings.

2. Structural Tripartite Division: CGST, SGST, and IGST

GST liability is categorized based on the geographical location of the supplier and place of supply:

  • Intra-State Transactions (CGST + SGST): Applied when the supplier and place of supply are located within the same Indian state/union territory. Revenue is split equally between the Central and State Governments.
  • Inter-State Transactions & Imports (IGST): Applied under the Integrated GST Act when transactions cross state boundaries or represent imports into India. IGST is collected by the Central Government and apportioned to the destination state.

3. Rigid Rules for Input Tax Credit (ITC) Claims under Section 16

Input Tax Credit (ITC) allows businesses to offset GST paid on purchases against their tax liability on sales. However, under Section 16(2) of the CGST Act, ITC cannot be claimed unless four cumulative conditions are satisfied:

  1. The buyer possesses a valid tax invoice or debit note issued by a registered supplier.
  2. The buyer has actually received the underlying goods or services.
  3. The supplier has actually paid the tax collected to the government (reflected in the buyerтАЩs auto-populated GSTR-2B statement).
  4. The buyer has furnished the monthly return under Section 39 (Form GSTR-3B).

4. Criminal Prosecution for Fake Invoicing & E-Way Bill Violations under BNS 2023

Non-Bailable Offenses under CGST Section 132 & BNS Section 318

Under CGST Section 132, issuing tax invoices without actual supply of goods/services (fake invoicing) or fraudulently availing ITC exceeding тВ╣5 Crores constitutes a Cognizable and Non-Bailable criminal offense punishable with imprisonment up to 5 years. Under BNSS Section 173 and BNS Section 318 (Cheating), tax authorities execute arrest warrants and bank account freezes (Section 83) during pending investigations.

5. Frequently Asked Questions (GST Law & Compliance)
