About the Advance Tax Calculator
If your total tax for the year (after TDS) is ₹10,000 or more, the Income Tax Act expects you to pay it in four instalments during the year rather than as a lump sum at the end. This calculator estimates your yearly tax, subtracts the TDS already deducted, and shows exactly how much to pay by each due date: 15 June, 15 September, 15 December and 15 March.
How to use it
- Pick the financial year and your tax regime.
- Enter your estimated annual income and any deductions (Old regime).
- Enter the TDS your employer or clients have already deducted.
- Read the four-instalment schedule with the cumulative percentage due by each date.
Freelancers, consultants, landlords and investors with income that isn't fully covered by TDS use this to avoid penal interest under Sections 234B and 234C. The maths runs entirely in your browser, so your income details stay private.
Frequently asked questions
Who has to pay advance tax?
Anyone whose total tax payable for the year, after reducing TDS, is ₹10,000 or more. Resident senior citizens without business income are exempt.
What are the advance-tax due dates?
You must have paid at least 15% of your tax by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March.
What happens if I miss an instalment?
Interest is charged under Section 234C for shortfalls in any instalment and under 234B if you've paid less than 90% of your tax by year-end. Paying on schedule avoids both.
