What Exactly Is Advance Tax?
Advance tax is essentially 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 Department requires you to pay it in instalments throughout the year as you earn the income.
This ensures a steady flow of revenue for the government and prevents a heavy financial burden on taxpayers at year-end. Any individual whose estimated tax liability for a financial year is ₹10,000 or more is required to pay advance tax.
My Employer Already Deducts TDS. Why Should I Care?
This is a common and crucial question. Your employer deducts Tax Deducted at Source (TDS) only on your salary income. However, if you have other income streams, the TDS from your salary likely won't cover the tax liability on that extra income. Advance tax becomes applicable when the total tax due, after accounting for all TDS, still exceeds the ₹10,000 threshold. Common sources of extra income for salaried individuals include capital gains from stocks or mutual funds, interest from fixed deposits, rental income from property, or earnings from freelance side-gigs.
The Instalment Deadlines: Focus on September 15
The Income Tax Act lays out a clear schedule for advance tax payments, split into four instalments. For the financial year 2026-27, the second deadline is September 15, 2026. By this date, you must have paid at least 45% of your total estimated advance tax for the year. The percentages are cumulative, meaning the amount paid in the first instalment (15% by June 15) is included in this 45% target. The subsequent deadlines are December 15 (75%) and March 15 of the next year (100%).
How to Calculate Your Advance Tax
Calculating your advance tax might seem daunting, but it can be broken down into simple steps. First, estimate your total income for the financial year from all sources—salary, interest, capital gains, rent, etc. Next, subtract any eligible deductions (like those under Section 80C or 80D) to arrive at your net taxable income. Then, calculate the total income tax on this amount based on your applicable tax slab. From this total tax liability, subtract the TDS that your employer will deduct from your salary and any other TDS already deducted from other incomes. If the remaining tax payable is more than ₹10,000, you are liable to pay advance tax. For the September 15 deadline, ensure you have paid 45% of this final amount.
What Happens If You Miss the Deadline?
Ignoring advance tax deadlines can lead to interest penalties. Under Section 234C of the Income Tax Act, interest of 1% per month is levied on the shortfall for the period of delay. For instance, if you fall short of the 45% payment by the September 15 deadline, you will incur interest for three months on the deficit amount. Furthermore, if your total advance tax paid by March 31 is less than 90% of your assessed tax, an additional interest under Section 234B at 1% per month is charged from April 1 until the tax is fully paid.
How to Make the Payment
Paying advance tax is a straightforward online process. You can pay it through the Income Tax Department's e-payment portal using net banking, debit cards, or other electronic methods. When filling out the challan (ITNS 280), be careful to select the correct Assessment Year (for income earned in FY 2026-27, the AY is 2027-28) and choose 'Advance Tax (100)' as the type of payment. Once the payment is made, be sure to save the challan receipt for your records.
