Advance Tax Calculator
Calculate advance tax instalments due dates and amounts for self-employed, freelancers, and companies in India.
About this calculator
Advance tax is income tax you pay during the year in four instalments instead of in one lump sum when you file. It applies if your tax liability after TDS is ₹10,000 or more in a year. Freelancers, business owners, landlords and investors with large capital gains are the usual payers.
This calculator estimates your annual tax for FY 2026-27 under the old or new regime, then splits it into the four due dates. The first instalment is 15% by 15 June, 45% cumulative by 15 September, 75% by 15 December and 100% by 15 March. Paying on time avoids interest under Sections 234B and 234C.
How to use it
- Enter your Estimated Annual Income.
- Choose your Category: individual, senior citizen or super senior citizen.
- Choose the Tax Regime.
- Enter Deductions you expect to claim if you chose the old regime.
- Press Calculate Advance Tax for the total tax and the instalment schedule.
Instalment schedule
Advance tax = estimated annual tax − TDS already deducted. Instalments fall due on 15 June: 15%, 15 September: 45% cumulative, 15 December: 75% cumulative and 15 March: 100%. Interest at 1% a month applies under 234C for each month of shortfall. Taxpayers under the presumptive scheme (44AD, 44ADA) can pay the full amount in one instalment by 15 March.
Worked example
Income ₹20,00,000, new regime
| Taxable income after ₹75,000 deduction | ₹19,25,000 |
| Annual tax with cess | ₹1,92,400 |
| By 15 June (15%) | ₹28,860 |
| By 15 September (45% cumulative) | ₹57,720 more |
| By 15 December (75% cumulative) | ₹57,720 more |
| By 15 March (100%) | ₹48,100 more |
Total ₹2,08,000 split as ₹31,200, ₹62,400, ₹62,400 and ₹52,000. Salaried people usually do not need to pay advance tax because TDS covers it, unless they have large other income.
Tips and common mistakes
- Include TDS already deducted. Only the balance is payable as advance tax.
- Pay through the challan on the income tax portal or net banking and keep the challan number.
- Resident senior citizens without business income are exempt from advance tax.
- If your income is lumpy, pay according to actual receipts and compute 234C carefully. Capital gains are only due from the quarter in which they arise.
- Round to the nearest ten rupees as the system does.
