Advance Tax Deadline for FY26 Nears: Taxpayers Must Pay Final Instalment by March 15, 2026

The final deadline to pay advance tax for the financial year 2025–26 is March 15, making it crucial for taxpayers to review their tax liabilities and ensure timely payment. Under the advance tax system, individuals and businesses whose total tax liability exceeds ₹10,000 after adjusting Tax Deducted at Source (TDS) must pay their taxes in instalments during the financial year rather than settling the entire amount at the time of filing their income tax return.

Failure to pay advance tax before the deadline can result in interest penalties under the Income Tax Act, which many taxpayers often overlook.

What is Advance Tax and Who Must Pay It

Advance tax is commonly known as the “pay-as-you-earn” tax system, where taxpayers pay their estimated tax liability in instalments throughout the year as income is earned.

This requirement applies when the total tax liability exceeds ₹10,000 after accounting for TDS.

Taxpayers who typically need to pay advance tax include:

• Salaried individuals earning additional income such as rent, interest, capital gains, or freelance income
• Freelancers and consultants
• Professionals including doctors, lawyers, and chartered accountants
• Business owners
• Any taxpayer whose tax liability after TDS crosses ₹10,000

However, senior citizens aged 60 years and above are exempt from paying advance tax if they do not earn income from business or professional activities.

Advance Tax Instalment Schedule and Penalties

Advance tax is paid in four instalments during the financial year. The schedule is structured to distribute the tax burden gradually.

The instalment deadlines are:

• June 15: Minimum 15% of total tax liability
• September 15: Minimum 45% (cumulative)
• December 15: Minimum 75% (cumulative)
• March 15: 100% of total tax liability

The March 15 deadline represents the final opportunity to settle the entire advance tax liability.

If taxpayers fail to pay advance tax on time, the Income Tax Department may impose penalties.

Interest under Section 234C is charged if instalments are delayed or not paid as per schedule. Meanwhile, Section 234B applies if a taxpayer fails to pay at least 90% of total tax liability by March 31.

In both cases, interest is levied at 1% per month or part of a month on the unpaid tax amount until the liability is cleared.

Conclusion

With the final advance tax deadline for FY26 falling on March 15, taxpayers should review their income and tax liability carefully to avoid penalties.
