Advance Tax Due Dates & How to Calculate It

Last updated: 27 June 2026 · Covers financial year 2026-27. Confirm on incometax.gov.in.

Advance tax is paid in four instalments — by 15 June, 15 September, 15 December and 15 March — if your total tax liability for the year is ₹10,000 or more after TDS. The cumulative percentages due are 15%, 45%, 75% and 100%. Taxpayers under presumptive taxation (Section 44AD/44ADA) pay the whole amount in a single instalment by 15 March. Paying short triggers interest under Sections 234B and 234C.

Key takeaways

Applies if your net tax liability (after TDS) is ₹10,000 or more for the year.
Four instalments: 15 Jun (15%), 15 Sep (45%), 15 Dec (75%), 15 Mar (100%) — cumulative.
Presumptive taxpayers (44AD/44ADA) pay 100% in one shot by 15 March.
Resident seniors with no business income are exempt from advance tax.
Shortfall interest: Section 234B (year-end short) and 234C (instalment short), both 1% per month.

Fact box. Advance tax is due in four instalments — 15 June, 15 September, 15 December and 15 March — building up to 15%, 45%, 75% and 100% of the year's tax liability.

Who has to pay advance tax?

You must pay advance tax if your total tax liability for the year, after deducting TDS, is ₹10,000 or more. This catches most proprietors, professionals, freelancers and companies with profits.

You are exempt if:

You are a resident senior citizen (60+) with no income from business or profession, or
Your total tax after TDS is below ₹10,000.

What are the advance tax due dates for FY 2026-27?

There are four instalments. Each is cumulative — by the second date, you should have paid 45% of the year's tax in total, not an extra 45%.

Instalment	Due date	Cumulative tax payable
1st	15 June 2026	15%
2nd	15 September 2026	45%
3rd	15 December 2026	75%
4th	15 March 2027	100%

Presumptive scheme. Taxpayers under Section 44AD (business) or 44ADA (profession) skip the four-instalment schedule and pay 100% of advance tax in a single instalment by 15 March.

How do I calculate advance tax?

Estimate your full-year income, work out the tax, subtract TDS already deducted, and pay the cumulative percentage by each date. Here is the method in five steps.

Estimate annual income from all sources for the year.
Compute tax on it using the applicable slab (new or old regime).
Add 4% health & education cess (and surcharge if income is high).
Subtract TDS/TCS already deducted on your behalf.
Pay the cumulative percentage due by each instalment date (15% / 45% / 75% / 100%).

Worked example

Suppose your estimated tax for the year (after TDS) is ₹1,00,000:

Date	Cumulative %	Total paid by then	This instalment
15 Jun 2026	15%	₹15,000	₹15,000
15 Sep 2026	45%	₹45,000	₹30,000
15 Dec 2026	75%	₹75,000	₹30,000
15 Mar 2027	100%	₹1,00,000	₹25,000

Fact box. A resident taxpayer who opts for presumptive taxation under Section 44AD or 44ADA pays the entire advance tax in one instalment by 15 March — there is no June, September or December instalment.

What happens if I miss an advance tax instalment?

You pay interest. Section 234C charges 1% per month for shortfalls in any individual instalment, and Section 234B charges 1% per month if you have paid less than 90% of your total tax by the end of the financial year. The tax is not lost — you can still pay it with the interest — but the cost compounds.
