The date of March 15 is extremely important for the final installment of advance tax. For the financial year 2025–26, this is the deadline for the fourth and final installment, through which taxpayers settle their entire tax liability. The advance tax system allows taxpayers to pay tax throughout the year based on their income, so that a large burden does not fall all at once at the end of the year.
In this article, we will understand in detail who should pay advance tax and what the consequences are of missing the deadline.
Who Should Pay Advance Tax?
Advance tax must be paid by all taxpayers whose estimated tax liability in a financial year is Rs 10,000 or more after deducting TDS or TCS. This rule comes under Section 208 of the Income Tax Act and applies to salaried individuals, freelancers, doctors, lawyers, consultants, business owners, and other professionals. If a salaried person has additional income such as rental income, capital gains, profits from the stock market or mutual funds, FD interest, dividends, gifts, or side income, they must also pay advance tax. It is also necessary to calculate and pay tax on crypto gains or sudden bonuses received.
On the other hand, certain exemptions are available. Resident senior citizens aged 60 years or older are not required to pay advance tax, provided they do not have any income from a business or profession. If the total tax liability after deducting TDS and TCS is less than Rs 10,000, advance tax is not required. Taxpayers opting for presumptive taxation must pay the entire 100% amount in a single installment by March 15. This system encourages taxpayers to take responsibility for their tax obligations based on their income while ensuring regular government revenue collection.
Advance Tax Installments
Advance tax is divided into four installments, which for the financial year 2025–26 are as follows:
- First installment: At least 15% of the total tax liability by June 15, 2025.
- Second installment: 45% (total tax liability) by September 15, 2025.
- Third installment: 75% (total tax liability) by December 15, 2025.
- Fourth and final installment: The remaining amount must be paid so that 100% of the liability is completed by March 15, 2026.
March 15, 2026, is the final opportunity for taxpayers to deposit the entire remaining amount.
This installment system gives taxpayers the flexibility to pay tax as they earn income. If there is unexpected income in any quarter, such as capital gains of Rs 3 lakh on September 1, the applicable tax can be calculated and paid in the remaining installments. Tax on income generated after March 15 must be paid by March 31. By completing installments on time, taxpayers can avoid the burden of interest and keep their financial planning on track.
What Will Happen if You Miss the Deadline?
If the March 15 deadline is missed or if there is a shortfall in installments, penal interest is charged under Sections 234B and 234C of the Income Tax Act. Under both sections, interest of 1% per month or part of a month is charged. Section 234C applies to shortfalls or delays in installments, while Section 234B applies when less than 90% of the total tax is paid by March 31. If 90% or more of the tax is deposited by March 31, interest under Section 234B can be avoided, although interest under Section 234C on shortfalls in earlier installments may still apply.
This interest continues to accrue until the date of actual payment and becomes an additional burden on the taxpayer. Missing the deadline not only leads to financial loss but can also create complications at the time of filing the Income Tax Return (ITR). Therefore, taxpayers should monitor their estimated income and take timely action to avoid unnecessary penalties. This rule promotes tax compliance and helps ensure the smooth collection of government revenue.
Wrapping Up
The deadline of March 15, 2026, is the last opportunity to fulfill the entire advance tax liability. All taxpayers with a tax liability of more than Rs 10,000 should complete their installments after making a correct estimate of their income. The burden of 1% monthly interest for missing the deadline not only leads to financial loss but can also complicate tax compliance.
Senior citizens and taxpayers with lower liabilities should make use of the available exemptions. With accurate calculation, timely payment, and regular monitoring, taxpayers can avoid penalties and maintain better financial discipline. Check your tax liability today and take action before March 15, 2026.
