How this is calculated +
When advance tax applies (Section 208): any taxpayer whose tax liability for the year (after TDS / TCS credits) is ₹10,000 or more is required to pay advance tax.
The four-instalment schedule (Section 211 for non-presumptive taxpayers):
By 15 June: 15% of total tax
By 15 September: 45% (cumulative)
By 15 December: 75% (cumulative)
By 15 March: 100% (full balance)
Presumptive taxpayers (Section 44AD for small businesses, 44ADA for professionals): a single instalment of 100% by 15 March. No earlier instalments required.
Net advance tax = Total tax liability − TDS − TCS − Advance tax already paid.
Senior citizen exemption (Section 207): a resident individual aged 60 or above who does not have income from business or profession is exempt from advance tax. The full tax liability is paid as self-assessment tax under Section 140A, typically by 31 July (the standard ITR due date for individuals).
Penalty for default (Sections 234B and 234C): interest at 1% per month on the shortfall from each instalment due date until paid. Even small under-payments attract interest, so paying slightly more than required at each instalment is good defensive practice.
Capital gains and dividend income: if you have a sudden capital gain or large dividend after an advance-tax due date, you can pay the corresponding tax in the next instalment without interest under Section 234C (a relief for unforeseen income).
Indicative only. The calculator assumes your tax estimate is accurate. In practice, advance tax estimation involves projecting the full year’s income mid-year, which has uncertainty. Under-estimation triggers interest under Sections 234B/234C; over-estimation locks up cash but is refunded with the ITR. Talk to us for help projecting your liability quarter by quarter.
