Advance Tax Calculator

Taxpayers whose estimated tax liability for the year, after subtracting TDS already deducted, crosses a specified threshold are generally required to pay advance tax in instalments rather than waiting until year-end.

TDS is deducted by someone else (the payer) on your behalf during a transaction. Advance tax is tax you estimate and pay yourself directly in instalments, typically relevant for income where no or insufficient TDS is deducted, like freelance or business income.

Paying less than required in instalments can attract interest for the shortfall when you file your return — this calculator helps you estimate a more accurate instalment amount upfront.

Salaried employees with tax fully covered by employer TDS usually don't need to pay advance tax separately, but those with significant additional income (capital gains, freelance work, rental income) may still need to.

Advance tax is typically paid in multiple instalments spread across the financial year rather than as a single annual payment — check current due dates on the income tax department's portal.
