Estimate your total tax for the year, reduce expected TDS/TCS, and get the exact instalment amounts payable by 15 June, 15 September, 15 December and 15 March. The calculator uses the current new-regime slabs (with Section 87A rebate and marginal relief) and the old-regime slabs, including senior-citizen limits.
Due date alert: The first advance tax instalment for FY 2026-27 (AY 2027-28) - 15% of your estimated annual tax - is due by 15 June 2026. Advance tax applies only where the estimated liability after TDS is Rs. 10,000 or more (Section 208). Resident senior citizens without business or professional income are exempt under Section 207.
Who must pay
Anyone whose estimated tax for the year, after TDS and TCS, is Rs. 10,000 or more - including freelancers, businesses, landlords and investors.
Instalment schedule
Cumulative 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March of the financial year.
Presumptive scheme
Taxpayers under section 44AD or 44ADA can skip the quarterly instalments and pay the full amount in one go by 15 March.
Calculate Advance Tax Instalments
Enter your estimated taxable income for the year after deductions (but before standard deduction — the calculator applies it for salary or pension income). The result includes Section 87A rebate, marginal relief and 4% cess.

Who is liable - Sections 208 and 207
Under Section 208, every person whose estimated tax liability for the year is Rs. 10,000 or more must pay tax in advance during the same financial year, in the instalments above. The liability is tested after reducing TDS and TCS that will be deducted or collected on your income. That is why most purely salaried employees never pay advance tax: the employer's monthly TDS already covers it. Advance tax typically becomes relevant when you have freelance or business income, rent, interest on deposits, dividends or capital gains on which little or no tax is deducted at source.
Section 207 gives a complete exemption to a resident senior citizen (aged 60 or more) who has no income from business or profession. Such a taxpayer can simply pay the entire balance as self-assessment tax while filing the return, without advance tax instalments or 234B/234C interest.
Worked Examples
Rs. 16,00,000 income (new regime)
Taxable income Rs. 16,00,000 with no TDS gives total tax of Rs. 1,24,800 (incl. 4% cess). Instalments: Rs. 18,720 by 15 June, Rs. 37,440 each by September and December, and Rs. 31,200 by 15 March 2027.
After Rs. 1,00,000 TDS
On the same income, expected TDS of Rs. 1,00,000 leaves net advance tax of Rs. 24,800. Each quarterly instalment shrinks proportionately. If net liability falls below Rs. 10,000, no advance tax is due.
Presumptive 44AD / 44ADA
Taxpayers under presumptive taxation can pay the entire advance tax in one instalment by 15 March instead of four quarterly payments — select the presumptive option in the calculator above.
Instalment breakdown: Rs. 16,00,000 example
Detailed schedule for FY 2026-27 with taxable income of Rs. 16,00,000 and no TDS:
| Due date | Cumulative % | Cumulative amount | Payable in this instalment |
|---|---|---|---|
| 15 June 2026 | 15% | Rs. 18,720 | Rs. 18,720 |
| 15 September 2026 | 45% | Rs. 56,160 | Rs. 37,440 |
| 15 December 2026 | 75% | Rs. 93,600 | Rs. 37,440 |
| 15 March 2027 | 100% | Rs. 1,24,800 | Rs. 31,200 |
If TDS of, say, Rs. 1,00,000 is expected on the same income, advance tax is computed on the net liability of Rs. 24,800 and each instalment shrinks proportionately. If the net figure falls below Rs. 10,000, no advance tax is due at all.
Interest under Sections 234B and 234C
Missing or short-paying instalments attracts simple interest at 1% per month. Because both sections work on your final figures, a realistic income estimate each quarter — revised at every instalment — is the cheapest way to stay compliant.
Section 234C — instalment shortfall
Charged on the shortfall in each instalment: 1% per month for 3 months on shortfalls at the June, September and December milestones, and 1% for one month on a shortfall at 15 March. Small tolerance margins apply (no interest if you paid at least 12% and 36% at the first two dates).
Section 234B — less than 90% paid
If total advance tax paid during the year is less than 90% of the assessed tax, interest at 1% per month runs from 1 April of the assessment year until the balance is paid.
Presumptive taxation and advance tax
Taxpayers who declare income under section 44AD (small businesses) or section 44ADA (specified professionals) get a major relaxation: instead of four instalments, the whole of the advance tax can be paid in a single instalment by 15 March. Select the presumptive option in the calculator to see this schedule. Note that if you also have other taxable income outside the presumptive business, the normal quarterly schedule can still apply to that portion.
How the calculator works
Rebate and cess
Applies the Section 87A rebate (up to Rs. 60,000 in the new regime for taxable income up to Rs. 12 lakh, with marginal relief just above it) and adds 4% health and education cess.
Reduce TDS / TCS
Subtracts the TDS and TCS you expect during the year and checks the Rs. 10,000 threshold and the Section 207 senior-citizen exemption.
Build the schedule
Splits the net liability into the 15% / 45% / 75% / 100% cumulative milestones - or one 15 March instalment for presumptive taxpayers.

Frequently Asked Questions
Who has to pay advance tax?
Anyone whose estimated tax for the year, after TDS and TCS, is Rs. 10,000 or more (Section 208). It commonly affects freelancers, businesses, landlords and investors whose income has little tax deducted at source.
Are senior citizens exempt from advance tax?
Yes. A resident senior citizen aged 60 or more with no business or professional income is fully exempt under Section 207 and can pay the balance as self-assessment tax while filing.
What are the advance tax due dates for FY 2026-27?
At least 15% of the estimated tax must be paid by 15 June 2026, 45% by 15 September 2026, 75% by 15 December 2026 and 100% by 15 March 2027. Taxpayers under presumptive taxation in sections 44AD or 44ADA can pay the entire amount in one instalment by 15 March 2027.
What happens if I miss an advance tax instalment?
Interest applies at 1% per month. Section 234C charges interest on the shortfall in each instalment, and Section 234B charges interest from 1 April of the assessment year if less than 90% of the assessed tax was paid as advance tax during the year.
Is TDS reduced before computing advance tax?
Yes. Instalments are computed on estimated tax minus the TDS and TCS expected to be deducted or collected during the year, and the Rs. 10,000 threshold is also tested on this net amount.
