Definitive Indirect Taxation & GST FAQs
Direct, authoritative statutory answers cited under the Central Goods and Services Tax Act 2017 for corporate CFOs, finance directors, and commercial founders.
- 01
How does Kinsmen resolve GST Input Tax Credit (ITC) discrepancies under CBIC Rule 88C and Rule 88D?
- Rule 88C triggers Form DRC-01B when outward liability in GSTR-1 exceeds tax paid in GSTR-3B beyond prescribed thresholds. Rule 88D triggers Form DRC-01C when ITC claimed in GSTR-3B exceeds ITC auto-populated in GSTR-2B. Kinsmen resolves these automated intimations by deploying 3-way algorithmic reconciliation (ERP Purchase Register vs GSTR-2B vs GSTR-3B), preparing transactional justification statements, verifying Section 16(2)(aa) compliance, and filing formal point-by-point replies on the portal within the strict 7-day window to prevent automatic GSTIN suspension under Rule 21A.
- 02
When is GSTR-9 and GSTR-9C mandatory, and what are the turnover thresholds?
- Under Section 44 of the CGST Act 2017 read with Rule 80, filing the Annual Return (GSTR-9) is mandatory for all regular taxpayers whose aggregate annual turnover exceeds ₹2 Crores. The self-certified Reconciliation Statement (Form GSTR-9C) is mandatory for enterprises with aggregate annual turnover exceeding ₹5 Crores. Both filings must be completed and submitted on the GST Portal by December 31 following the close of the financial year.
- 03
What are the legal consequences of non-compliance with the E-Invoicing mandate under Rule 48(4)?
- Entities with aggregate annual turnover exceeding ₹5 Crores in any financial year from 2017-18 onwards must mandatorily generate an Invoice Reference Number (IRN) and signed QR code through the Invoice Registration Portal (IRP) for all B2B and export supplies. Under Rule 48(5), an invoice issued without an IRN is legally deemed invalid. This exposes the supplier to a penalty of ₹25,000 per invoice under Section 122, and denies the buyer Input Tax Credit under Section 16.
- 04
How can exporters claim a full GST refund on inverted duty structures and zero-rated supplies?
- Exporters can claim refunds either under Letter of Undertaking (LUT) without IGST payment (accumulated unutilized ITC on inputs and input services) or on payment of IGST with automated customs rebate. For inverted duty structures (where raw material tax exceeds output tax), refunds are computed strictly under Rule 89(5) formulas. Kinsmen prepares Form RFD-01, compiles bank realization certificates (e-BRC/FIRC), resolves deficiency memos (RFD-03), and liaises directly with divisional officers until the sanction order (RFD-06) is issued.
