  • If the shortfall in payment of Advance Tax occurs due to capital gains or winning lottery, etc. then no interest is levied on the taxpayer.
  • The taxpayer has paid in full – tax payable on the income mentioned above, while paying remaining installments of advance tax due, or if no installments are due, the taxpayer pays them before the end of the financial year.


Consider that Aman total tax liability for this financial year is Rs. 100,000 and he paid Rs. 5,000 before 15th June, Rs. 25000 before 15th Sep, 35,000 before 15th December. He had some shortfall in every installment he paid. So by 31st of March, he paid total Rs. 53,000. The remaining Rs.50,000 was paid on 10th of July next year while filing the tax return.

If however, you made partial payments instead, you will be liable to pay interest as per the last column in the table below:
