ITR Advance Tax Deadline: As the last month of the year approaches, tax-related responsibilities suddenly seem overwhelming. Salaried individuals, freelancers, business owners, and taxpayers earning from investments all have the same question on their minds: how to avoid missing any deadlines. December 2025 presents one such crucial deadline – the third installment of advance tax. Ignoring this deadline can lead to penalties and interest charges.
Why is December 15, 2025, so important?

According to the Income Tax Department, the last date for paying the third instalment of advance tax for the financial year 2025-26 is Monday, December 15, 2025. Taxpayers liable for advance tax must pay their due share of tax liability by this date. Failure to pay on time can result in interest charges later, disrupting your tax planning.

What is Advance Tax and why is it necessary?
Advance tax means paying tax before the end of the financial year. This system, established under Sections 207 to 219 of the Income Tax Act, prevents taxpayers from facing a lump-sum tax burden at the end of the year. Tax is paid in instalments, providing the government with regular revenue and making payments easier for taxpayers.
Who is required to pay Advance Tax?
Individuals whose total tax liability exceeds a certain limit are required to pay advance tax. This includes income from salary, freelance work, business profits, rental income, and gains from shares or mutual funds. If the TDS deducted on your income does not cover your entire tax liability, you are responsible for paying advance tax.
The complete process of Advance Tax installments
The Income Tax Department has a system for collecting advance tax in four installments throughout the financial year. Each installment has a fixed due date, and taxpayers must pay tax on their estimated income accordingly. The third installment, due in December, is considered particularly important because by this time, your annual income is largely clear.
How to pay tax before December 15th
The process of paying advance tax is now completely online and easy. You can make the payment through a challan on the official Income Tax website. Tax can be paid using net banking, debit cards, or other digital methods. It is essential to keep the receipt safe after payment, as it is required when filing your ITR.
What happens if you don’t pay on time?
If a taxpayer fails to pay the third installment of advance tax by December 15, 2025, interest may be levied. This interest is charged under various sections of the Income Tax Act. This amount can gradually increase and may cause problems later when filing your ITR.
How advance tax simplifies tax planning
Advance tax is not just a legal obligation, but it also strengthens your financial planning. Paying taxes in installments avoids a sudden large expense and minimizes the impact on your savings. Additionally, timely tax payment provides peace of mind.
Why timely information is crucial

Every year, many people miss deadlines simply due to a lack of information. By knowing the advance tax dates in advance and accurately estimating your income, you can avoid unnecessary stress. It is wise to start preparing now, keeping the December 15, 2025 deadline in mind.
