Compute the four quarterly advance tax instalments under the corresponding advance-tax provisions of the Income-tax Act, 1961 (earlier Section 208 of the 1961 Act), net of TDS / TCS already deducted. Applicable when the estimated tax liability exceeds ₹10,000 in a financial year.
Enter your estimated annual income tax liability (after rebates and surcharge) and the TDS / TCS already deducted. The calculator splits the balance into the four statutory instalments due on 15 June, 15 September, 15 December, and 15 March.
Income earned in FY 2025-26 (1 Apr 2025 – 31 Mar 2026) is assessed in AY 2026-27 under the Income-tax Act, 1961. The new Income-tax Act, 2025 applies from FY 2026-27 onwards.
Under Section 208 of the Income Tax Act, 1961, advance tax is payable in four instalments during the financial year if the estimated tax liability (after TDS/TCS) exceeds ₹10,000:
Shortfall in any instalment attracts simple interest under Section 234C at 1% per month for three months (one month for the 15 March instalment) on the shortfall amount. Section 234B levies further 1% per month on any shortfall on assessment.
Exceptions: Resident senior citizens (60+) with no business income are exempt from advance tax (Section 207(2)). Taxpayers opting for presumptive taxation under Section 44AD / 44ADA may pay 100% of advance tax by 15 March in a single instalment.
Capital gains, lottery winnings, and other one-time income are taxed in the instalment immediately following the receipt of such income, without Section 234C interest if the gain could not have been estimated earlier.
