Quick summary
Income tax is meant to be paid as income is earned. TDS does this for salary, interest and similar income. For the rest, the law asks the taxpayer to pay advance tax during the financial year. In the Income-tax Act, 2025 (from 01/04/2026) these rules are in sections 403 to 410, and self-assessment tax is in section 266.
Advance tax = tax on your estimated current income at the rates in force minus the tax that will be deducted or collected at source during the year on income included in that estimate (section 405). You estimate the income yourself and pay on your own accord (section 406). After any instalment you can raise or lower the remaining instalments to match a revised estimate.
| Instalment | Due on or before | Cumulative advance tax payable |
|---|---|---|
| 1 | 15 June | Not less than 15% |
| 2 | 15 September | Not less than 45% |
| 3 | 15 December | Not less than 75% |
| 4 | 15 March | 100% |
Presumptive taxpayers. A person who declares profits under section 58(2) (Table Sl. No. 1 or 3), that is, the business scheme or the specified profession scheme, pays the whole advance tax by 15 March (section 408(2)). Goods carriage operators under Table Sl. No. 2 follow the four-instalment table.
Any sum paid on or before 31 March counts as advance tax of that financial year for all purposes (section 408(3)).
Example. Tax on estimated income is ₹1,80,000 and TDS of ₹30,000 will be deducted during the year, so advance tax is ₹1,50,000. The instalments are: ₹22,500 by 15 June; a cumulative ₹67,500 by 15 September (so ₹45,000 more); a cumulative ₹1,12,500 by 15 December (₹45,000 more); and the balance, ₹37,500, by 15 March.
An Assessing Officer can order advance tax from a person already assessed, on the higher of the income in the latest regular assessment or the income in any later return. The order must be passed by the last day of February and is followed by a demand notice (section 407(1) to (3)). If a later return or assessment follows, the order can be amended before 1 March (section 407(4) and (5)). You can reply with your own lower estimate, but if your estimate is higher, you must pay on the higher figure by the last instalment (section 407(8) and (9)). Failure to follow the order, or to send the intimation in time, makes you an assessee in default (section 409). Advance tax is credited in the regular assessment for the tax year in which it was payable (section 410).
After taking into account advance tax, TDS and TCS, tax relief and foreign tax credit, any tax that remains payable on the basis of your return is self-assessment tax. You must pay it, with the interest and fee payable for a delay in filing or a default in advance tax, before you furnish the return, and the return must carry proof of payment (section 266(1)). If you pay less than the total, the payment is applied first to the fee, then to the interest, then to the tax (section 266(3)).
Interest is charged at 1% a month on shortfalls and delays under sections 424 and 425, explained in the post on interest for delay and default in the Income-tax Act, 2025. Presumptive taxpayers who miss 15 March are charged 1% on the shortfall (section 425(3)).

Any assessee whose tax payable for the year, after TDS and TCS on income that is taxed, is ₹10,000 or more (sections 404 and 405). A resident individual who is 60 years or more at any time in the tax year and has no income from business or profession does not have to pay advance tax (section 403(3)).
15% by 15 June 2026, 45% by 15 September 2026, 75% by 15 December 2026 and 100% by 15 March 2027, each as reduced by the amounts already paid (section 408(1)).
If you declare profits under section 58(2) for a business or a specified profession (Table Sl. No. 1 or 3), the whole advance tax is due on or before 15 March (section 408(2)).
An amount paid on or before 31 March is treated as advance tax paid in that financial year (section 408(3)), but interest for the shortfall at the earlier instalment dates is still charged under section 425.
Tax still payable on the basis of the return after crediting advance tax, TDS, TCS, tax relief and foreign tax credit. It must be paid, along with interest and fee for any delay in filing or default in advance tax, before the return is furnished, and the return must carry proof of payment (section 266). If the payment is short, it is applied first to the fee, then interest, then tax.
Yes. If you have already been assessed, the Assessing Officer can require advance tax on the higher of your last regularly assessed income or the income in a later return, by an order passed no later than the last day of February (an amended order before 1 March), followed by a demand notice. You can send an intimation if you estimate a lower figure, and you must pay more if your own estimate is higher (section 407).
