Your PAN Card will be inoperative if you don't do this within Tomorrow
The deadline issued by the government in merging the PAN card with the Aadhaar card comes to and end tomorrow. In case if you don't merge your PAN card with the Aadhaar card you may even data-face a fine of upto Rs.10,000. But so far, very few have merged and most of them never merged their PAN card and Aadhaar card. Apart from the fine, your PAN card will also go invalid.
Also, if the money transaction crosses more than Rs.50,000 you might have to pay a huge sum as a fine. You can merge this with an SMS. You need to send UIDPAN (12 digit Aadhaar number) to 56768 or 56161. You will get a confirmation within few minutes.
