Sample Auditor's Report for GST Late Fees/Penalties
Form 3CD – Clause 21(a): Auditor's Reporting Note
| Particulars | Amount Debited to P&L (₹) | Disallowance u/s 37(1) (₹) |
|---|---|---|
| GST Late Fees (CGST + SGST) | 50,000 | 50,000 |
| GST Penalty u/s 122 CGST Act | 1,00,000 | 1,00,000 |
| Interest on GST u/s 50 CGST Act | 25,000 | Nil (Allowed) |
| Total Disallowance | 1,75,000 | 1,50,000 |
Auditor's Comment:
The assessee has debited to the Profit & Loss Account certain amounts towards "Late Fees" and "Penalty" under the Central Goods and Services Tax Act, 2017 for delayed filing of statutory returns and other non-compliance.
In view of Explanation 1 to Section 37(1) of the Income-tax Act, 1961, any expenditure incurred for any purpose which is an offence or prohibited by law is not allowable as a deduction while computing business income.
Accordingly, the Late Fees and Penalty under GST are inadmissible business expenses, being penal in nature.
However, Interest on delayed payment of GST under Section 50 of the CGST Act is compensatory in nature and hence allowable as a deduction under Section 37(1).
Tax Computation Adjustment:
Profit as per P&L Account: ₹10,00,000
Add: GST Late Fees / Penalty (disallowed u/s 37(1)): ₹1,50,000
Less: Interest on GST (allowed): Already debited, no adjustment
Taxable Business Income: ₹11,50,000
