What Exactly Is Advance Tax?
Think of advance tax as a 'pay-as-you-earn' system for your annual income tax. Instead of settling your entire tax bill in a lump sum after the financial year ends, the government 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, one-time financial burden on taxpayers. The rule is simple: if your estimated total tax liability for the financial year is ₹10,000 or more, you are required to pay advance tax.
Who Needs to Pay?
The advance tax net is wide and covers various types of taxpayers. You are liable if you are a salaried individual with additional income from other sources like rent, capital gains, interest, or dividends that isn't fully covered by your employer's TDS. It also applies to freelancers, consultants, and business owners who don't have tax deducted at source. Essentially, any individual, firm, or company whose net tax liability crosses the ₹10,000 threshold must pay. 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.
The September 15 Deadline
The Income Tax Department has set four key dates for advance tax payments. The second instalment is due on or before September 15, 2026. By this date, you must have paid at least 45% of your total estimated tax liability for the year. It is important to note that this is a cumulative percentage. If you have already paid the first instalment of 15% by June 15, you only need to pay the remaining 30% to meet the 45% cumulative requirement by the September deadline.
Calculating Your Second Instalment
To calculate your advance tax, first, you need to estimate your total income for the entire financial year (April 1, 2026, to March 31, 2027). From this, subtract any deductions you are eligible for. Apply the applicable income tax slab rates to this net taxable income to arrive at your gross tax liability. Finally, deduct any Tax Deducted at Source (TDS) or Tax Collected at Source (TCS) that has already been accounted for. If this final amount exceeds ₹10,000, it is your advance tax liability. For the second instalment, calculate 45% of this total liability and subtract the amount you paid in the first instalment.
The Cost of Missing the Deadline
Failing to pay or underpaying your advance tax instalment has financial consequences. The Income Tax Act levies penal interest under Section 234C for deferment of instalments. If your cumulative payment by September 15 is less than 45% of your assessed tax, you will be charged simple interest at 1% per month for three months on the shortfall amount. Furthermore, if the total advance tax paid by the end of the financial year is less than 90% of your assessed tax, an additional interest under Section 234B is levied at 1% per month from April 1 of the next year until the tax is fully paid.
How to Make Your Payment
Paying advance tax is a straightforward digital process. You can pay it online through the official Income Tax e-Filing portal. On the portal, select the 'e-Pay Tax' option, enter your PAN, and choose 'Advance Tax' as the payment type. You can complete the payment using various methods, including net banking, debit card, UPI, or RTGS/NEFT. After successful payment, a challan receipt (ITNS 280) is generated, which serves as proof of payment and should be saved for your records.
