As per the rules, it is mandatory to link PAN with Aadhaar before the March 31 deadline. With the Supreme Court (SC)upholding the government requirement that PAN must be mandatorily linked with Aadhaar, Section 139AA of the Income Tax Act comes into play. As per this section, if your PAN is not linked with Aadhaar by a date to be notified by the government then it would be deemed to become invalid. Currently, the deadline for this has not been set by the government although those who have filed ITR for FY16-17 without linking PAN with Aadhaar are required to do the same by March 31, 2019. 

Failing which, users will not be able to file Income Tax returns or claim refund. Also, if there is a mistake in your PAN card and you have not got them corrected then you will not be able to complete important tasks like filing the income tax return. PAN card is a mandatory document for financial transactions and filing tax returns.

PAN card details of several people are printed incorrectly. These may include spelling of the user's Name, father's name or birthdate. If this is the case with you then correct it soon, otherwise, you will not be able to file income tax returns. For the first time, people who have filed their returns may not be aware that a slight mistake in PAN card or ITR form can prove costly.

There is no need to feel hassled to update the PAN card. You can update it online, from the comfort of your home in a few minutes. However, you need to have all the necessary information before updating.
