Question 1

Which GST provisions govern input tax credit eligibility and restrictions?

Accepted Answer

Section 16 of the CGST Act 2017 sets four conditions for ITC: possession of a valid tax invoice, actual receipt of goods or services, tax paid by the supplier to the government, and a return filed under Section 39. Section 17 blocks ITC on motor vehicles (subject to exceptions), food and beverages, club memberships, and construction of immovable property. Section 16(4) imposes a hard cutoff — ITC cannot be claimed after the due date of the September return of the following financial year or the date of filing the annual return, whichever is earlier.

Question 2

What is the GSTR-2B matching requirement and what happens when ITC is claimed in excess?

Accepted Answer

Rule 36(4) of the CGST Rules 2017 caps provisional ITC at the amount reflected in auto-populated GSTR-2B for that tax period. Credit claimed beyond the GSTR-2B figure is treated as excess under Section 73 (non-fraud cases) or Section 74 (fraud or suppression), attracting tax recovery, interest at 18% per annum under Section 50, and penalties ranging from 10% to 100% of the tax amount. The ITC audit reconciles GSTR-2A/2B against the purchase register and books of account to surface and rectify these gaps before a departmental notice is issued.

Question 3

How do Rule 42 and Rule 43 reversals apply to mixed-use inputs and capital goods?

Accepted Answer

Where inputs or input services are used partly for taxable supplies and partly for exempt supplies or non-business purposes, Rule 42 of the CGST Rules 2017 requires proportionate reversal computed using the exempt-to-total turnover ratio. For capital goods with dual use, Rule 43 prescribes a 60-month amortisation of common ITC with monthly reversal. Both are trued up annually and must be correctly reflected in Form GSTR-9 and the reconciliation statement in Form GSTR-9C. The ITC audit computes and documents these reversals to prevent a demand under Section 73.

Question 4

When does the GST department initiate a special audit and how does a proactive ITC audit help?

Accepted Answer

Under Section 66 of the CGST Act 2017, the Commissioner can direct a registered person to get a special audit conducted by a CA or Cost Accountant nominated by the Commissioner, where the complexity of the case or interest of revenue so demands. This is triggered when the department believes ITC has been wrongly availed or turnover is understated. A taxpayer-commissioned ITC audit — reconciling GSTR-2B, purchase registers, and books before departmental scrutiny — substantially reduces the risk of a Section 66 direction and any associated penalty exposure under Section 74.

Question 5

What records must be maintained to defend ITC claims during a GST audit or scrutiny?

Accepted Answer

Section 36 of the CGST Act requires every registered person to retain specified records for 72 months from the due date of the annual return for that year. Rule 56 of the CGST Rules prescribes the minimum records: purchase register, original tax invoices and debit/credit notes, stock register, and an account of goods dispatched for job work under Section 143. For capital goods, Rule 43 requires a separate ITC utilisation register showing credit availed year-wise per asset. The ITC audit verifies that these records exist, reconcile to GSTR-2B, and are available at the principal place of business registered under the GST certificate.
