Advance Tax Deadline: Final Instalment Due by 15 March 2026 for FY 2025–26

Taxpayers in India must remember that 15 March 2026 is the last date to pay the fourth and final instalment of advance tax for Financial Year 2025–26. Advance tax is also known as “pay as you earn” tax, where taxpayers pay their tax liability in instalments during the year instead of paying the entire amount at the end of the financial year.

Paying advance tax on time helps taxpayers avoid interest penalties and remain compliant with the Income Tax rules.

What is Advance Tax?

Advance tax refers to the income tax paid in advance during the financial year based on the estimated income of the taxpayer. It applies to individuals, freelancers, professionals, and businesses whose total tax liability after TDS/TCS exceeds ₹10,000 in a financial year.

Instead of paying the full tax amount at the time of filing the Income Tax Return (ITR), the tax is paid in instalments throughout the year.

Important Advance Tax Deadlines for FY 2025–26

For most taxpayers, advance tax must be paid in the following instalments:

• 15 June – 15% of total tax liability
   
• 15 September – 45% of total tax liability
   
• 15 December – 75% of total tax liability
   
• 15 March 2026 – 100% of total tax liability
   

The 15 March instalment is the final payment, where taxpayers must ensure that the entire estimated tax liability has been paid.

Can Advance Tax Be Paid After 15 March?

Yes, any tax paid on or before 31 March 2026 is still considered advance tax. However, if the taxpayer fails to pay the required amount by 15 March, interest penalties may be applicable under the Income Tax Act.

Who Needs to Pay Advance Tax?

Advance tax is mandatory for taxpayers whose estimated tax liability exceeds ₹10,000 in a financial year after considering TDS and TCS.

It generally applies to:

• Salaried individuals with additional income (rent, interest, capital gains, etc.)
   
• Freelancers and professionals
   
• Business owners
   
• Investors earning capital gains or other taxable income
   

Exemption from Advance Tax

Certain taxpayers are exempt from paying advance tax.

Resident senior citizens (aged 60 years or above) who do not have income from business or profession are not required to pay advance tax.

Advance Tax for Presumptive Taxation

Taxpayers who opt for presumptive taxation under Sections 44AD or 44ADA (small businesses and professionals) have a different rule.

They are required to pay the entire 100% advance tax in a single instalment by 15 March instead of paying it in multiple instalments during the year.

Penalties for Missing the Advance Tax Deadline

If advance tax is not paid on time or the amount paid is insufficient, the Income Tax Department may charge interest under the following sections:

Section 234C
If the required instalment is not paid by 15 March, interest at 1% per month for one month may be charged on the shortfall.

Section 234B
If a taxpayer fails to pay at least 90% of the total tax liability by 31 March, interest at 1% per month may be charged until the tax is fully paid.

Why Timely Advance Tax Payment is Important

Paying advance tax on time helps taxpayers:

• Avoid interest penalties
   
• Maintain proper tax compliance
   
• Reduce the burden of paying a large tax amount at once
   
• Ensure smooth Income Tax Return filing
   

Conclusion

With the final advance tax deadline of 15 March 2026 approaching, taxpayers should review their estimated income and tax liability for FY 2025–26 and ensure that the full tax amount is paid before the due date. Timely payment will help avoid unnecessary penalties and interest charges.
