Half of December has already passed, and December, the last month of the year, is considered very important for taxpayers. Before the year ends, there are several important financial tasks whose deadlines are this month. If these tasks are not completed by the deadline, taxpayers may face penalties, interest, and other problems. Many experts also say that this may be the last chance for those who have not yet completed these important tasks. So, let's tell you today which important tasks you need to complete now that half of December is over, otherwise you might face problems.

Last chance for ITR filing

Taxpayers who were unable to file their income tax return on time can file a delayed or revised e-return under Section 139(4) of the Income Tax Act.

Delayed Return

Taxpayers who were unable to file their original ITR even by December 15th have until December 31st as their last chance. Those who haven't filed their original ITR can now file it by December 31st. However, a late fee of up to Rs. 5000 may be applicable. For taxpayers with an annual income of less than Rs. 5 lakh, this fee is capped at Rs. 1000.  In addition, interest will also be charged on the outstanding tax.

Revised Return

Those who filed their ITR return on time but want to correct or amend any errors in the return can also file a revised or updated return by December 31st. However, if there is a tax liability, an additional penalty of 25 to 50 percent may be levied. The last date for Aadhaar-PAN linking is also December 31st.

Linking Aadhaar and PAN cards is mandatory for individuals whose Aadhaar cards were issued on or before October 1, 2024. This process must be completed by December 31, 2025. Failure to link by the deadline may result in the PAN card becoming inactive, which could cause problems with banking, investments, and filing income tax returns.
