Penalty Late Fee Quantitative Computation Matrix
Statutory precision predictable liability assessment.
Late Fee Structure Precise:
GSTR-3B: ₹100 CGST + ₹100 SGST = ₹200/day
GSTR-1: ₹50 CGST + ₹50 SGST = ₹100/day
GSTR-4: ₹100 CGST + ₹100 SGST = ₹200/day
GSTR-9: ₹200/day turnover >₹2 Cr
Maximum Cap:
GSTR-3B: ₹5,000 (25 days)
GSTR-1: ₹2,000 (20 days)
GSTR-4: ₹5,000 (25 days)
GSTR-9: ₹10,000 (50 days)[web:488]
Interest Computation Algorithm:
Formula: Net Tax Liability × 18% × Days/365
Example: ₹10L CGST May20-Jun25 (35 days)
Interest = 10L × 0.18 × 35/365 = ₹17,260
Pro-rata: 0.0493%/day precision[web:321]
Practical Scenario:
ABC Ltd Apr25 GSTR-3B ₹10L tax May 20 notice:
Days Delay: 30 → Late Fee ₹6,000 (capped)
Interest: ₹15,000 → Total ₹21,000
File May 25 → GSTR-3A auto-closed[web:487]
