What is Advance Tax?

Advance tax is the income tax you pay in installments during the financial year, rather than paying the entire amount as a lump sum at the end of the year. It is also known as the "pay-as-you-earn" scheme. The Income Tax Department requires taxpayers to estimate their annual income and pay tax on it in four quarterly installments.

Under Section 208 of the Income Tax Act, 1961, any person whose estimated tax liability for the year exceeds ₹10,000 (after subtracting TDS) is required to pay advance tax. This applies to self-employed professionals, business owners, freelancers, and salaried employees who have income from other sources such as capital gains, rental income, or interest income.

• Advance tax applies to all taxpayers, including individuals, HUFs, firms, and companies, whose tax liability exceeds ₹10,000 in a financial year
• It must be paid in four installments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15
• Senior citizens (60 years and above) who do not have income from business or profession are exempt from paying advance tax
• Failure to pay advance tax on time attracts interest under Section 234B and Section 234C of the Income Tax Act

How is Advance Tax Calculated?

Advance tax is calculated by estimating your total annual income from all sources, applying the applicable income tax slab rates, and then subtracting any TDS already deducted. The remaining tax liability is divided into quarterly installments.

Here is the step-by-step process:

Advance Tax Calculation with Example

Let us calculate advance tax for a freelance consultant with an estimated annual income of ₹25,00,000 under the new tax regime for FY 2025-26, with ₹2,00,000 already deducted as TDS by clients.

Note: Standard deduction of ₹75,000 (new regime) or ₹50,000 (old regime) applies only to salaried employees, not to freelancers or business professionals. The quarterly installments would be:

Advance Tax Due Dates for FY 2025-26

Advance tax must be paid in four installments during the financial year. Each installment has a specific due date and a cumulative percentage of the total tax liability that should be paid by that date.

Taxpayers who opt for the presumptive taxation scheme under Section 44AD or 44ADA can pay the entire advance tax in a single installment by March 15. They are not required to follow the quarterly schedule.

If a due date falls on a Sunday or public holiday, the payment can be made on the next working day without attracting interest.

Why is Advance Tax Important?

Paying advance tax on time is not just a legal obligation. It helps you manage your cash flow, avoid penalties, and stay compliant with income tax regulations. Here is why advance tax matters for business owners, professionals, and freelancers:

• Avoid interest penalties: Late or short payment of advance tax attracts interest under Section 234B (1% per month on shortfall) and Section 234C (1% per month for deferment). These charges can add up significantly over the year
• Better cash flow management: Paying tax in four installments spreads your tax burden across the year, making it easier to manage business expenses and personal finances
• Accurate financial planning: Estimating your income quarterly forces you to review your earnings and expenses regularly, leading to better financial decisions
• Smooth ITR filing: When advance tax is paid correctly, your ITR filing becomes straightforward with minimal tax payable or refundable at the end of the year
• Government compliance: The income tax department tracks advance tax payments. Consistent non-payment may attract scrutiny or notices from the department

Who Needs to Pay Advance Tax?

Advance tax is applicable to a wide range of taxpayers. Here is a clear breakdown of who needs to pay and who is exempt:

• Self-employed professionals: Doctors, lawyers, chartered accountants, architects, consultants, and other professionals whose income is not subject to TDS must pay advance tax
• Business owners: Proprietors, partners, and directors of companies with tax liability exceeding ₹10,000 must pay advance tax on business profits
• Freelancers and gig workers: Independent contractors, content creators, and gig economy workers who receive payments without TDS deduction need to pay advance tax
• Salaried employees with other income: If you earn rental income, capital gains from stock market or mutual funds, fixed deposit interest, or freelance income in addition to your salary, and the extra tax liability exceeds ₹10,000, you need to pay advance tax
• Companies and firms: All companies (including LLPs and partnership firms) must pay advance tax regardless of the amount, following the same quarterly schedule

Interest on Late Payment of Advance Tax (Section 234B and 234C)

The Income Tax Act imposes two types of interest for non-payment or short payment of advance tax. Understanding these penalties helps you plan your payments and avoid unnecessary costs.

Section 234B: Interest for Default in Advance Tax

Section 234B applies when you fail to pay at least 90% of your assessed tax liability as advance tax. Interest is charged at 1% per month (simple interest) on the shortfall amount.

Section 234C: Interest for Deferment of Advance Tax

Section 234C applies when you pay advance tax installments late or pay less than the required percentage by each due date. Interest is charged at 1% per month for 3 months on the shortfall for each quarter.

Both interest charges are mandatory and cannot be waived. The best way to avoid them is to estimate your income accurately and pay advance tax on time. Use our old vs new tax regime calculator to determine which regime results in lower tax, and then plan your advance tax payments accordingly.
