   • Sec 47(1), CGST Act 2017Late fee of ₹100 per day under CGST (and an equal amount under SGST) up to ₹5,000 for late returns and statements, reduced by notification for many returns.
   • Sec 50(1), CGST Act 2017Interest is payable on tax paid late for the period of delay at the notified rate (18 percent a year); on a late return it is levied only on the portion paid in cash, except where proceedings under Sec 73, 74 or 74A have started.
3. A

   Analysis

   A monthly 3B filed 15 days late with ₹30,000 cash tax attracts late fee of ₹50 a day, ₹750 (as reduced by notification), plus interest of about ₹222. Both are paid in cash. Late fee is fixed per day; interest depends on the tax amount. Paying tax early by challan avoids interest even if the return is late.
