Understanding Advance Tax in India

Advance Tax refers to income tax that is paid in installments as income is earned during the financial year, rather than as a single lump sum after the year ends. Taxpayers pay advance tax in India on their estimated taxable income in four installments across the year, as prescribed under the Income Tax Act, 1961. Missing or underpaying these installments triggers interest charges that compound the longer the shortfall continues, which makes accurate estimation, not just eventual payment, the part that actually matters.

Who Should Pay Advance Tax under Section 208 of the Income Tax Act

As per Section 208 of the Act, advance tax is payable during a financial year wherever the estimated tax liability is INR 10,000 or more. There is one exemption: advance tax does not apply to a resident individual if both of the following conditions are satisfied:

• The individual does not have any income chargeable under the head “Profits and Gains of Business or Profession”; and
• The individual is 60 years of age or older at any time during the relevant previous year.

This means salaried individuals, freelancers, professionals, and business owners with a tax liability above the threshold are all within scope the exemption is narrow and specific to senior citizens with no business or professional income.

How to Calculate Advance Tax in India

Calculating advance tax starts with estimating your total annual income from all sources for the financial year salary, business or professional income, capital gains, rental income, and any other taxable income. Apply the applicable income tax slab rates (or the relevant rate for companies) to arrive at your estimated total tax liability for the year. Subtract any tax already deducted at source (TDS) or tax collected at source (TCS), since advance tax is payable only on the balance liability.

Worked Example

Suppose a self-employed professional estimates their total tax liability for the year at INR 1,80,000, and TDS already deducted on their professional fees comes to INR 30,000. Their advance tax liability is the difference: INR 1,50,000. Applying the standard four-installment schedule, this person would pay INR 22,500 (15%) by 15th June, a cumulative INR 67,500 (45%) by 15th September, a cumulative INR 1,12,500 (75%) by 15th December, and the full INR 1,50,000 (100%) by 15th March, with each installment calculated as the cumulative percentage of total liability, less whatever has already been deposited.

Advance Tax Due Dates and Payment Percentages

Advance tax in India is payable in installments according to the following schedule, which applies uniformly across financial years unless specifically amended by the Finance Act:

Exception: Taxpayers Under the Presumptive Taxation Scheme

Taxpayers who have opted for the presumptive taxation scheme under Section 44AD (eligible businesses) or Section 44ADA (eligible professionals) follow a different and simpler schedule. Rather than the four-installment structure above, they are required to pay 100% of their advance tax liability in a single installment, on or before 15th March of the financial year. This is a common point of confusion for small business owners and professionals who default to the standard four-installment assumption and either overpay early or miscalculate their position.

How to Pay Advance Tax

Advance tax is paid online through Challan 280 on the Income Tax Department’s e-filing portal (incometax.gov.in), under the “e-Pay Tax” service. Payments can be made via net banking, debit card, or other supported modes linked to authorized banks. It is important to select the correct assessment year and the correct payment type (“Advance Tax”) on the challan, since errors here can complicate credit reconciliation at the time of filing the return.

Consequences of Non-Compliance

As per Section 234B, where the advance tax paid by a taxpayer is less than ninety percent of their assessed tax, the taxpayer is liable to pay simple interest at one percent per month (or part of a month) on the shortfall below ninety percent. Interest under Section 234B runs from the first day of the assessment year until the date the income is determined under Section 143(1) or until a regular assessment is completed.

Section 234C levies interest at one percent per month (or part of a month) for default in payment of any individual installment, calculated at the specified rates for the specified period. Interest under Section 234C is levied for one month in the case of a shortfall in the final (15th March) installment and for three months in the case of a shortfall in the first, second, or third installments. In practice, this means underpaying early installments and “catching up” later still attracts interest for the period of the shortfall; there is no benefit to deferring payment within the year.
