How it works
Advance tax means paying your income tax in instalments through the year instead of one lump sum at filing time. Anyone whose net tax liability is ₹10,000 or more in a year must pay it.
This calculator uses the new-regime slabs for FY 2026-27:
Tax = slab rates on (Gross − ₹75,000 standard deduction − deductions), 87A rebate if ≤ ₹12L, + 4% cess
- Instalments: 15% by 15 June, 45% cumulative by 15 September, 75% by 15 December, 100% by 15 March. The amounts above are what you pay each quarter, not running totals.
- 87A rebate: taxable income up to ₹12 lakh pays zero tax; just above ₹12 lakh, marginal relief keeps the extra tax proportional.
- Shortfall interest: section 234B charges 1%/month if advance tax falls below 90% of your liability; 234C charges 1%/month for quarterly shortfalls.
- Exemption: resident senior citizens (60+) with no business income need not pay advance tax at all.
Frequently asked questions
What is advance tax?
Paying your income tax in instalments during the year instead of one payment at filing. If your total tax liability for the year is ₹10,000 or more, you must pay it in advance.
Who has to pay advance tax?
Salaried people, freelancers, and businesses whose net tax (after TDS/TCS) is ₹10,000 or more. Salaried employees usually have it covered by employer TDS, but rental, interest, or freelance income can push you over the threshold.
What are the due dates and percentages?
15 June (15%), 15 September (45% cumulative), 15 December (75% cumulative), 15 March (100%). The amounts shown above are the marginal payment due each quarter.
What happens if I miss a deadline?
Interest under 234B (1% per month if advance tax is below 90% of total liability) and 234C (1% per month for each quarterly shortfall). Paying late is always better than not paying.
Are senior citizens exempt from advance tax?
Yes — resident individuals aged 60+ with no income from business or profession are exempt. They can pay their full tax while filing the return.
If TDS already covers my tax, do I still pay advance tax?
No. Advance tax applies only to the net liability after TDS/TCS. If your employer or bank already deducted enough, nothing more is due in advance.
How is advance tax different from self-assessment tax?
Advance tax is paid during the financial year in instalments. Self-assessment tax is paid after the year ends, before filing, to settle any remaining balance.
What if my income estimate changes mid-year?
Revise your estimate and adjust the remaining instalments — the law only cares that the cumulative percentages are met by each due date. Overpaying is fine; the excess comes back as a refund.
What is the ₹10,000 rule?
Under section 208, advance tax is payable only if your net tax liability for the year is ₹10,000 or more. Below that, just pay while filing.
Does this calculator use the new or old regime?
The new regime (FY 2026-27): ₹75,000 standard deduction, 87A rebate up to ₹12 lakh, 4% cess. Most 80C-type deductions are not available in the new regime — the deductions field is for any other allowable reductions.
