What Exactly Is Advance Tax?
Think of advance tax as a 'pay as you earn' system for your total 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, one-time burden on the taxpayer. The system applies to most forms of income that are not typically subject to Tax Deducted at Source (TDS), or where TDS is not sufficient to cover the total tax due. This includes income from a business, profession, capital gains, rental income, and interest on deposits.
Who Needs to Pay by September 15?
The rule is simple: if your total estimated tax liability for the financial year (after deducting TDS) is ₹10,000 or more, you are required to pay advance tax. This applies to individuals, freelancers, consultants, and businesses alike. Salaried individuals who have significant additional income—such as from stock market gains, freelance projects, or rent—that isn't covered by their employer's TDS deductions also fall under this mandate. However, there is an important exemption: resident senior citizens (aged 60 and above) who do not have any income from a business or profession are not required to pay advance tax.
Understanding the 45% Payment
The September 15 deadline marks the second of four advance tax instalments for the financial year. By this date, you must have paid a cumulative total of at least 45% of your total estimated tax liability for the year. The first instalment, due on June 15, required a payment of 15%. So, the payment due in September is the difference required to bring your total paid amount up to the 45% mark. The subsequent deadlines are December 15 (for 75%) and March 15 (for 100%). Taxpayers using the presumptive taxation scheme under sections like 44AD and 44ADA have a different rule; they can pay their entire liability in a single instalment by March 15, 2027.
How to Calculate and Pay Your Instalment
To calculate your payment, you first need to estimate your total income from all sources for the entire financial year (April 1, 2026, to March 31, 2027). Next, calculate the income tax payable on this estimated income according to the applicable tax slabs. From this total tax amount, subtract any TDS that has been or will be deducted. If the remaining amount is over ₹10,000, that is your advance tax liability. For the September 15 deadline, you must ensure that the total tax paid to date is at least 45% of this liability. You can pay online through the income tax e-filing portal using Challan 280. The portal allows payment via net banking, debit card, and other electronic modes.
The Consequences of Missing the Deadline
Failing to pay the correct amount of advance tax on time is not advisable, as it attracts interest penalties. If you pay less than the required 45% by September 15, interest under Section 234C of the Income Tax Act will be levied. This is calculated at a rate of 1% simple interest per month for three months on the shortfall amount. Furthermore, if your total advance tax payments for the year are less than 90% of your final assessed tax, you will also face interest under Section 234B, which is charged at 1% per month from the beginning of the next financial year until the tax is fully paid. These penalties are calculated automatically when you file your return, so timely compliance is the most cost-effective approach.
