The deadline (March 15) for the fourth and final installment of advance tax has passed. If you are a salaried employee who earned additional income during the financial year but missed making the required advance tax payment, you might think that interest under Section 234C is now unavoidable.
However, salaried employees who primarily earn income through salary generally have TDS deducted by their employers, which covers their tax liability. But if they have additional income—such as interest, rental, or capital gains—they may be required to pay advance tax to avoid interest penalties under Section 234C.

Even if you missed the March 15 advance tax deadline, you can still prevent Section 234C interest by paying any outstanding tax liability before March 31.

Missing the March 31 deadline can have consequences
If you fail to pay advance tax or arrange for additional TDS deduction by this date, you may incur interest under Section 234C for delaying tax payments. Moreover, Section 234B interest will apply if at least 90 per cent of your total tax liability remains unpaid by March 31. This interest accrues at 1 per cent per month until you file your Income Tax Return (ITR). Therefore, March 31 is your final opportunity to avoid both types of interest penalties.
“In case you missed the March 15 deadline, then you must request your employer to deduct additional taxes from your salaries by submitting requisite information,” said SR Patnaik, partner (head - taxation), Cyril Amarchand Mangaldas.
