Advance Tax Calculator
4 installments: June · September · December · March
Total income tax + surcharge + 4% cess for the year
TDS cut by employer + bank TDS on FDs etc.
Advance tax due if net liability > Rs 10,000. Interest u/s 234B: 1%/month if <90% paid. 234C: 1%/month on shortfall per quarter.
If your tax liability (after TDS) exceeds Rs 10,000 in a year, you must pay advance tax. Missing installments attracts 1% per month interest u/s 234B and 234C. Freelancers, business owners, and investors with capital gains or dividend income are most commonly caught by advance tax requirements.
What is Advance Tax?
Advance tax is income tax paid in installments during the financial year, rather than as a lump sum at filing time. The principle is "pay as you earn." If your total tax liability (after TDS) exceeds Rs 10,000 in a year, you are required to pay advance tax in four quarterly installments — by 15 June, 15 September, 15 December, and 15 March.
Who needs to pay advance tax?
Advance tax applies to: freelancers and self-employed professionals, business owners, salaried employees with significant side income (capital gains, FD interest, rent, dividends), investors who booked large capital gains during the year, and senior citizens who are not salaried but have business income. Senior citizens (60+) without business income are exempt from advance tax.
Quarterly installment percentages
The installment schedule is: 15% of estimated annual liability by 15 June, 45% cumulative by 15 September, 75% cumulative by 15 December, and 100% by 15 March. For taxpayers using the presumptive taxation scheme (Section 44AD/44ADA), the entire advance tax can be paid in one shot by 15 March.
Penalty for missing advance tax
Section 234B: 1% per month simple interest on the shortfall if you pay less than 90% of your total tax liability by 31 March. Section 234C: 1% per month interest on the shortfall in each quarterly installment. These penalties compound quickly — missing all four installments on a Rs 1 lakh tax liability attracts Rs 12,000 in 234B interest for the full year. Always pay advance tax on time.
