First, What Is Advance Tax?
Advance tax is a 'pay-as-you-earn' system for income tax. Instead of paying your entire tax liability in a lump sum after the financial year ends, the Income Tax Act requires you to pay it in instalments throughout the year in which the income is earned.
This system ensures a steady flow of revenue for the government and prevents a heavy financial burden on taxpayers at the end of the year. The core principle 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 is wide and covers more than just business owners. You are liable if your net tax liability (after accounting for any Tax Deducted at Source, or TDS) exceeds ₹10,000 for the financial year. This includes: Salaried Individuals with Other Income: If you have income from sources like rent, capital gains, freelance work, or high-interest fixed deposits that are not reported to your employer for TDS purposes, you likely need to pay advance tax. Freelancers and Professionals: Self-employed individuals like doctors, lawyers, consultants, and digital creators must pay advance tax on their professional income. Business Owners: All businesses and companies are liable to pay advance tax. Those under the presumptive taxation scheme (Section 44AD/44ADA) have a different schedule, requiring them to pay their full tax in one go by March 15. NRIs: Non-Resident Indians who earn taxable income in India, such as from property or investments, are also required to pay advance tax if their liability crosses the ₹10,000 threshold. The main exemption is for resident senior citizens (aged 60 and above) who do not have any income from a business or profession. They are not required to pay advance tax.
Understanding the September 15 Deadline
Advance tax is paid in four instalments. The September 15 deadline is for the second instalment of the financial year 2026-27. By this date, you must ensure that your cumulative advance tax payment is at least 45% of your total estimated tax liability for the year. This is a cumulative figure. For instance, if you already paid 15% by the first deadline on June 15, you need to pay an additional 30% by September 15 to reach the 45% minimum.
How to Calculate and Pay Your Instalment
Calculating your advance tax involves a few steps. First, estimate your total income from all sources for the entire financial year (April 1, 2026, to March 31, 2027). Apply the relevant income tax slab rates to this estimated income to calculate your gross tax liability. From this 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 have paid at least 45% of this total liability. To pay, you can use the 'e-Pay Tax' service on the official Income Tax e-Filing portal. You will need to enter your PAN, select the assessment year (2027-28 for income earned in FY 2026-27), and choose 'Advance Tax' as the payment type. Payments can be made via net banking, debit card, UPI, or other available methods.
The Cost of Missing the Deadline
Failing to pay or underpaying your advance tax instalments has financial consequences. The Income Tax Act levies interest penalties under two key sections. Interest under Section 234C is charged at 1% per month for three months on the shortfall amount for the specific instalment you missed or underpaid. For example, if you fell short by ₹20,000 on the September 15 instalment, you would face interest on that amount. Additionally, if by the end of the financial year (March 31), you have paid less than 90% of your total assessed tax, a separate interest under Section 234B is levied at 1% per month on the deficit from April 1 until the date of payment.
