A number of crucial financial and tax compliance chores must be finished by midnight today,December 31, 2025, otherwise people and businesses risk fines, inoperative PAN status, delayed refunds, or restricted financial transactions.
Here is a brief rundown of the important due dates and tasks you must do before the end of the day:
Today is the deadline for PAN-Aadhaar linking.
The last day to link your PAN (Permanent Account Number) with your Aadhaar is December 31, 2025, according to the Income Tax Department.
Your PAN will become inactive on January 1, 2026, if you don't link by today. This means you won't be able to create bank or demat accounts, file ITRs, get tax refunds, or do many other financial operations.
If they haven't already linked, the majority of taxpayers have to pay an online cost of ₹1,000 before completing the linking request. Some PAN holders may be exempt if they obtained their PAN after October 1, 2024, using an Aadhaar enrollment ID.
If your PAN stops working, you can revive it later by finishing the linking and paying the required amount.
Action tip: Visit the Income Tax e-filing portal, go to ‘Link Aadhaar’, enter PAN & Aadhaar, complete payment, and submit before midnight.
Submit updated or delayed ITRs by today.
The deadline for filing a revised or belated Income Tax Return (ITR) for the Assessment Year 2025-26 (FY 2024-25) is December 31 if you failed to file your initial return on time or if it had errors.
Penalties, interest, and delayed refunds could result from filing an ITR after the deadline.
Refunds and tax credits can be processed more smoothly if errors are fixed with a corrected return by today.
Action tip: Before the deadline, log in to the tax portal, choose "File Belated/Revised Return," change the information, and e-verify the return.
GST Annual Returns Could Be Due Today as Well
The deadline for completing annual return files and other compliance procedures for registered businesses under the Goods and Services Tax (GST) regime is typically December 31. You can be subject to late fees and penalties if you fail to do this.
Action tip: Before the end of the day, finish any outstanding yearly returns and reconciliation, and check the GST filing status on the GST portal.
The Significance of This Deadline
If these deadlines are missed, PAN may become inoperable, preventing financial and tax transactions.
Increased interest and penalties for late filing of GST and ITRs
Tax refunds that are delayed or blocked
Problems with financial transactions (opening accounts, expensive purchases)
