Work out your four advance tax instalments for FY 2024-25 — due dates, cumulative percentages and the exact amount payable at each stage.
How advance tax instalments work
Advance tax is the "pay-as-you-earn" tax under Section 208 of the Income Tax Act. If your total tax liability for the year (after TDS/TCS) is ₹10,000 or more, you must pay it in four instalments through the year rather than in one lump sum at filing. Each due date carries a cumulative target — the percentage shown is the total that should be paid by that date, and the incremental amount is what you actually deposit at that point.
| Due Date | Cumulative |
|---|---|
| On or before 15 June | 15% |
| On or before 15 September | 45% |
| On or before 15 December | 75% |
| On or before 15 March | 100% |
| Income | Rate |
|---|---|
| Up to ₹3 lakh | Nil |
| ₹3L – ₹7L | 5% |
| ₹7L – ₹10L | 10% |
| ₹10L – ₹12L | 15% |
| ₹12L – ₹15L | 20% |
| Above ₹15L | 30% |
Interest for missing or short-paying advance tax
Section 234C levies interest at 1% per month for deferment — i.e. if you fall short of the cumulative percentage due on any instalment date. The shortfall at each date is charged 1% per month for the relevant period.
Section 234B applies when the total advance tax paid during the year is less than 90% of the assessed tax. It charges 1% per month on the unpaid amount from 1 April of the assessment year until the tax is finally paid. Paying each instalment on time and in full is the only way to avoid both.
Frequently asked questions
Who has to pay advance tax?
Any taxpayer — salaried, self-employed, freelancer, business owner or company — whose total tax liability for the year, after reducing TDS and TCS, is ₹10,000 or more must pay advance tax. Resident senior citizens (60+) with no business or professional income are exempt from advance tax.
How is each instalment calculated?
The percentages are cumulative, not per-instalment. By 15 June you should have paid 15% of your net liability, by 15 September a cumulative 45%, by 15 December 75%, and by 15 March the full 100%. The incremental amount you actually pay on each date is the gap between that cumulative target and what you have already deposited (15%, then 30%, 30% and 25%).
What happens if I miss an advance tax instalment?
Missing or short-paying triggers interest under Section 234C at 1% per month on the shortfall for each instalment. If your total advance tax for the year is below 90% of the assessed tax, Section 234B adds a further 1% per month from 1 April of the assessment year until you pay. There is no penalty as such, only interest.
Does TDS reduce my advance tax?
Yes. Advance tax is payable only on your net liability — your estimated total tax minus the TDS and TCS that will be deducted on your salary, interest, contractor payments and so on. Enter the TDS already deducted in the calculator and it is subtracted before the instalments are worked out.
Can I pay all my advance tax at the end of the year?
Only taxpayers under the presumptive taxation scheme (Sections 44AD / 44ADA) may pay the entire advance tax in one instalment by 15 March. For everyone else, paying it all at year-end will attract Section 234C interest for the earlier instalments you skipped.
