What Exactly Is Advance Tax?
Think of advance tax as a 'pay-as-you-earn' system for your annual income tax. Instead of paying your entire tax liability in a lump sum at the end of the financial year, the government requires you to pay it in instalments throughout the year. This ensures
a steady flow of revenue for the government and prevents a heavy financial burden on taxpayers at year-end. The rule is simple: if your estimated tax liability for the financial year is ₹10,000 or more, you are required to pay advance tax.
Who Is Required to Pay?
The advance tax net covers a wide range of taxpayers. It is not just for businesses and freelancers. Even salaried individuals must pay it if they have significant other income. You are liable if you fall into any of these categories and your tax due exceeds ₹10,000 after accounting for any Tax Deducted at Source (TDS). This includes salaried employees with substantial income from other sources like rent, capital gains from shares or property, or high interest from fixed deposits. It also covers self-employed professionals, consultants, and business owners of all sizes.
Are There Any Exemptions?
Yes, there is a key exemption. Resident senior citizens—individuals aged 60 years or older—are not required to pay advance tax, provided they do not have any income from a business or profession. If a senior citizen's income comes only from sources like pension, rental income, or interest, they are exempt from the advance tax process and can settle their full tax liability when filing their return. Additionally, anyone whose total tax liability for the year is less than ₹10,000 is not required to pay advance tax.
The September 15 Deadline Explained
Advance tax is paid in four quarterly instalments. The September 15, 2026, deadline is for the second instalment of the Financial Year 2026-27. The payments are cumulative. Here is how the schedule works:
By June 15: You must pay at least 15% of your total estimated tax liability.
By September 15: You must have paid a cumulative total of at least 45% of your tax liability. This means if you paid 15% in June, you need to pay another 30% now.
By December 15: A cumulative total of 75% must be paid.
By March 15: The full 100% of your advance tax must be paid.
How to Calculate Your Payment
To calculate your advance tax, first estimate your total income for the financial year from all sources (salary, business, capital gains, interest, etc.). From this gross income, subtract any eligible deductions you plan to claim (like those under Section 80C or 80D) to arrive at your net taxable income. Apply the applicable income tax slab rates to this amount to find your total tax liability for the year. Finally, subtract any TDS that has already been deducted or will be deducted. If the remaining amount is over ₹10,000, that is your advance tax liability for the year, which you must pay according to the instalment schedule.
What If You Miss the Deadline?
Missing an advance tax deadline or underpaying an instalment leads to interest penalties under the Income Tax Act. There are two key sections that apply. Section 234C levies interest for deferment of instalments. If you fall short of the 45% cumulative payment by September 15, a penal interest of 1% per month is charged on the shortfall amount for a period of three months. Separately, Section 234B applies if the total advance tax paid by the end of the financial year (March 31) is less than 90% of your final assessed tax. In this case, interest of 1% per month is charged on the deficit from April 1 of the next year until the tax is fully paid.
