how to calculate advance tax

Income tax is normally paid after the end of the financial year, however if estimated net tax liability is Rs.10,000 or more during the financial year then tax payer should pay tax in the same financial year in 4 instalments at specified dates. Advance tax is collected by the government to prepone revenue collection from certain group of tax payers.

How to calculate advance tax ?

Advance tax is calculated as estimated tax, the final liability may be more or less at the time of income tax return filing for business. Just assume that financial year had ended and based on the information available calculate estimated net tax liability. Advance tax is estimated net tax liability so it includes educational cess surcharge if any and after deducting expected TDS rebate etc.


Example :

Estimated tax liability is Rs.1,00,000 (Including educational cess)

TDS expected to be deducted Rs.20,000

So the advance tax should be calculated on Rs.80,000 (Rs.1,00,000 – Rs.20,000).

How much advance tax should be paid in each instalment ?

There are 4 instalments available for advance tax payment as follows

1 st installment – 15 %
2 nd installment – 45 %
3rd installment   – 75 %
4th installment    – 100 %

At the time of each installment date of advance tax payment we need to recalculate advance tax and the mentioned % of total advance tax should be completely paid as on the date of payment of installment.


Total advance tax calculated at the time of 1 st instalment is 1,00,000

first instalment is Rs.1,00,000 * 15 % = 15,000 Rs.

Second instalment is 45 % of Rs.1,00,000 Less advance tax already paid  so advance tax liability is  Rs.1,00,000 * 45 % = Rs.45,000 Less Rs.15,000 paid during first installment so net payment during second installment is Rs.30,000.

while re calculating advance tax for third instalment we came to know that total estimated tax will be Rs.1,20,000, then we should calculate 75 % on Rs.1,20,000 which is Rs.90,000 and deduct advance tax already paid Which comes to Rs.45,000 (Rs.90,000 – Rs.45,000).

4 th installment is 100 % of estimated tax liability which is Rs.1,20,000 Less Rs.90,000, so at the time of 4 th installment we need to pay Rs.30,000.

At each stage we should re estimate and pay advance tax as per current position.

Due date for Each installment

  • 15 th June – 15 %
  • 15 th September – 45 %
  • 15 th December – 75 %
  • 15 th March – 100 %
