December Deadline: Get this important work done before 31st December, otherwise you will have to pay heavy fine

December Deadline: The last month of the year 2025, December, is now in its final stages. Today is 22nd December 2025, that means only 9 days are left for the year to end. In such a situation, there are some very important financial tasks whose deadline is 31 December 2025. If you do not complete these tasks on time, you may have to face fines, additional interest and many other problems.

1. Filing belated income tax return (ITR)

If you have not yet filed your income tax return for the financial year 2024-25, then the last chance is till 31 December 2025. After this you will not be able to file returns. For late filing of returns, those with annual income less than Rs 5 lakh will have to pay Rs 1,000 and those with annual income Rs 5 lakh or more will have to pay Rs 5,000 as late fee.

Disadvantages of not filing ITR on time

If a refund is generated in your return, it may be stuck or not available. Under the Tax Act, penalty and interest may have to be paid, which increases the tax burden.

Frequent non-filing of returns weakens the tax profile, which can affect loan, credit score and visa applications. The Income Tax Department remains more vigilant and the chances of receiving a notice increase.

2. Linking Aadhaar and PAN

If you have made Aadhar card on or before October 1, 2024 and have not yet linked it to PAN card, then it is necessary to do this by December 31, 2025. If your PAN is not linked, it may become inoperative. This will cause problems in banking, investment and ITR filing.

This is the whole process

• Go to the Income Tax e-filing website.

• Complete the linking with the help of PAN number, Aadhaar number and OTP received on mobile.

• If there is any penalty, you can pay it online.

• If desired, this process can also be completed through SMS.
