What Exactly Is Advance Tax?
Think of advance tax as a 'pay-as-you-earn' system for your taxes. Instead of paying a large lump sum at the end of the financial year, the Income Tax Department requires you to pay your taxes in instalments throughout the year in which you earn the income.
This ensures a steady flow of revenue for the government and prevents a heavy financial burden on you when it's time to file your return.
Who Needs to Pay Advance Tax?
The rule is simple: if your estimated total tax liability for the financial year (after accounting for any Tax Deducted at Source or TDS) is ₹10,000 or more, you are required to pay advance tax. This applies to almost everyone, including salaried individuals who have other sources of income. For example, if you have a full-time job but also earn income from freelancing, capital gains on stocks, rental income, or even interest from fixed deposits, you likely need to pay advance tax on that additional income. Business owners and self-employed professionals like doctors, lawyers, and consultants are also liable. The only major exemption is for resident senior citizens (aged 60 and above) who do not have any income from a business or profession.
The September 15 Deadline Explained
The Income Tax Department has set four deadlines for advance tax payments. The upcoming one is September 15, 2026. By this date, you should have paid at least 45% of your total estimated advance tax for the financial year 2026-27. This percentage is cumulative. It means that if you paid the first instalment of 15% by the June 15 deadline, you now need to pay an additional 30% to reach the 45% mark. If you missed the first instalment, you should now pay the entire 45% to get back on track.
How to Calculate Your Second Instalment
Calculating your advance tax might seem daunting, but it can be broken down into simple steps. First, estimate your total income from all sources for the entire financial year (April 1, 2026, to March 31, 2027). Next, subtract any applicable deductions you plan to claim, such as those under Section 80C. This gives you your net taxable income. Now, calculate the tax on this income based on the applicable slab rates for your chosen tax regime (old or new). From this total tax amount, subtract any TDS that your employer or clients will deduct during the year. If the remaining amount is more than ₹10,000, this is your advance tax liability. To find your second instalment amount, calculate 45% of this total liability and subtract whatever you already paid in the first instalment.
The Price of Missing the Deadline
Ignoring advance tax deadlines can be costly. The Income Tax Act has provisions for levying interest for non-payment or deferment. Under Section 234C, a simple interest of 1% per month is charged for three months on the shortfall amount for each instalment you miss or underpay. Furthermore, if you haven't paid at least 90% of your total tax liability by the end of the financial year, you could face interest under Section 234B, which is also calculated at 1% per month on the unpaid amount from April 1 of the next year until you pay it. These penalties can add up, making compliance not just a legal duty but a financially prudent one.
