Who is Obligated to Pay Advance Tax in India?

Advance tax, often referred to as the 'pay-as-you-earn' scheme, is not just for large corporations. Under Section 208 of the Income Tax Act, 1961, any taxpayer whose estimated net tax liability for the financial year exceeds Rs 10,000 (after deducting TDS and TCS) is legally required to pay their taxes in advance. This mandate applies to:

• Salaried Individuals: If you have substantial income from other sources such as rental income, capital gains, or interest on fixed deposits that is not covered by your employer's TDS.
• Freelancers and Professionals: Independent consultants, doctors, lawyers, and digital creators.
• Businesses and Corporates: All corporate entities and partnership firms.
• Presumptive Taxation Users: Individuals opting for Section 44AD or 44ADA (though their schedule differs slightly, requiring 100% payment by March 15).

Note: Senior citizens (aged 60 years or above) who do not run a business or profession are exempt from paying advance tax.

The Advance Tax Installment Schedule: Where Do You Stand?

The Income Tax Department of India structures advance tax payments into four distinct quarters. Understanding this schedule helps you plan your cash flow and avoid year-end tax shocks. The schedule for FY 2026-27 is as follows:

• On or before June 15: 15% of the total estimated tax liability.
• On or before September 15 (The Second Installment): 45% of the total estimated tax liability (minus any amount paid in the first installment).
• On or before December 15: 75% of the total estimated tax liability (minus amounts already paid).
• On or before March 15: 100% of the total estimated tax liability (minus amounts already paid).

Missed the September 15 Deadline? Understanding the Penalties

If you failed to meet the Advance Tax second installment deadline of September 15, 2026, you will be liable to pay interest under Section 234C of the Income Tax Act.

• The Interest Rate: The Income Tax Department levies a simple interest of 1% per month (or part of a month) on the short payment.
• The Duration: Since the installments are quarterly, the 1% interest under Section 234C is generally calculated for a period of three months on the deficit amount.
• The Calculation: If your cumulative payment by September 15 was less than 45% of your total tax liability, you will owe 1% interest per month for three months on the difference between what you should have paid (45%) and what you actually paid.

However, there is a small buffer: if you paid at least 36% of your total tax liability by the September 15 deadline (instead of the full 45%), the interest under Section 234C for this specific quarter will not be levied.
