  • Nil GSTR-3B, 12 days late: 12 × ₹20 = ₹240.
  • GSTR-3B, turnover ₹80 lakh, 30 days late: 30 × ₹50 = ₹1,500 (below the ₹2,000 cap) = ₹1,500.
  • GSTR-1, turnover ₹3 crore, 150 days late: 150 × ₹50 = ₹7,500, capped at ₹5,000.
  • GSTR-9, turnover ₹3 crore (all in one State), 300 days late: 300 × ₹50 = ₹15,000, capped at 0.04% of ₹3 crore = ₹12,000.
