1. F

   Facts

   Under the fixed sum method, paying the system-generated amount on time means no interest for the first two months, even if actual tax was higher. Under self-assessment, interest applies on any short payment for the delay.

2. P

   Provisions and law

   • 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.
   • Rule 87, CGST Rules 2017Deposits in the electronic cash ledger are made through the PMT-06 challan.
3. A

   Analysis

   Under fixed sum, if the system asks for ₹35,000 and you pay it by the 25th, no interest arises for that month, even if actual tax is ₹40,000; the gap is paid in the quarterly 3B. Under self-assessment, short payment carries 18 percent interest from the 25th. Choose the method that suits your cash flow, but stay consistent within the quarter.

4. C

   Conclusion

   1. 1Choose fixed sum or self-assessment each month.
   2. 2Pay by the 25th of the next month.
   3. 3Under self-assessment, pay actual tax to avoid interest.
   4. 4Settle the balance in quarterly 3B.
