How the Advance Tax Calculator Works
Advance tax is the “pay-as-you-earn” system under Indian income tax: instead of paying everything at year-end, you pay your liability in four instalments through the year. This calculator takes your estimated total tax and the TDS already deducted, then splits the balance across the four statutory due dates so you know exactly how much to pay and when.
The Formula
First find the amount on which advance tax is due:
Net advance tax = total tax liability − TDS/TCS already deducted
Then apply the cumulative schedule from Section 211 of the Income Tax Act:
By 15 June → 15% of net By 15 September → 45% cumulative By 15 December → 75% cumulative By 15 March → 100%
Each instalment is the cumulative target for that quarter minus what you should already have paid by the previous quarter.
Worked Example
Suppose your estimated tax for the year is 1,20,000 and no TDS has been deducted:
- Net advance tax = 1,20,000 − 0 = 1,20,000
- By 15 June: 15% = 18,000
- By 15 September: 45% cumulative = 54,000, so this instalment = 54,000 − 18,000 = 36,000
- By 15 December: 75% cumulative = 90,000, so this instalment = 90,000 − 54,000 = 36,000
- By 15 March: 100% = 1,20,000, so the final instalment = 1,20,000 − 90,000 = 30,000
Instalment Schedule
| Due date | Cumulative % | Cumulative due | This instalment |
|---|---|---|---|
| 15 June | 15% | 18,000 | 18,000 |
| 15 September | 45% | 54,000 | 36,000 |
| 15 December | 75% | 90,000 | 36,000 |
| 15 March | 100% | 1,20,000 | 30,000 |
Who Needs to Pay
You must pay advance tax if your net liability is 10,000 or more after TDS. This commonly applies to the self-employed, business owners, freelancers, and salaried people with significant extra income from interest, capital gains or rent that is not fully covered by TDS. Resident senior citizens without business income are exempt.
Avoiding Interest
Missing the schedule triggers interest under Section 234B (for paying less than 90% of the liability by year-end) and Section 234C (for deferring individual instalments), each at 1% per month. Re-estimate your income each quarter and top up the instalment if your income has risen.
This calculator handles the standard instalment schedule and does not compute your underlying tax liability or any interest. It is a general estimator, not tax advice — confirm current rules for your assessment year and consult a qualified professional before paying.
Frequently asked questions
What are the advance tax due dates in India?+
Advance tax is paid in four instalments: at least 15% of the liability by 15 June, 45% cumulatively by 15 September, 75% cumulatively by 15 December, and 100% by 15 March. These dates and percentages are set by Section 211 of the Income Tax Act and apply to most individual and corporate taxpayers.
Who has to pay advance tax?+
Any taxpayer whose total tax liability for the year, after subtracting TDS and TCS, is 10,000 or more must pay advance tax. Resident senior citizens (aged 60+) with no income from business or profession are exempt.
How is advance tax calculated?+
Estimate your total income tax for the year, subtract the TDS and TCS already deducted, and pay the balance in the four scheduled instalments. By 15 June you pay 15% of that net figure; the cumulative target rises to 45%, 75% and finally 100% by 15 March.
What happens if I miss an advance tax instalment?+
Shortfalls attract interest under Sections 234B and 234C, charged at 1% per month on the unpaid amount. Paying each instalment on time, in line with the 15/45/75/100 percent schedule, avoids this interest.
Do presumptive taxpayers pay advance tax in instalments?+
No. Taxpayers declaring income under the presumptive schemes of Section 44AD or 44ADA pay their entire advance tax in a single instalment, on or before 15 March of the financial year, rather than in four parts.
