How can you link PAN and Aadhar?
The process can be completed on www.incometaxindiaefiling.gov.in, the official e-filing portal by following a few simple steps –

• Register on the Income tax e-filing portal if you have not done earlier.
• If you are an already registered user on e-filing portal,
• Login to e-filing portal of Income tax department by entering your PAN as User ID, password, date of birth and CAPTCHA code.
• A pop up window appears prompting you to link your PAN with Aadhaar.
  • You can input your Aadhaar number and your name and click on ‘link now’.
• No pop up window appears,
  • Go to the menu option – ‘Profile Setting’ and click on ‘Link Aadhaar’.
  • Enter your Aadhaar number and your name as per Aadhaar and click on ‘Link Aadhaar’.
• The system will match your name, date of birth and gender in the PAN and Aadhaar databases.
• If details are matching,
  • You will get the message “Aadhaar – PAN linking is completed successfully.”
  • If you have registered an email address with the portal, you will get an email confirming the same.
• If the details are not matching,
  • You will get an appropriate error message. ​

If the name in the Aadhaar card is different, you can log in to the Aadhaar website and request for a name change. You need to upload a scanned copy of PAN card as proof. The only requirement is that the registered mobile number has to be operational.
If the name on the PAN card is not the appropriate one, you can request for change of name here.
There is also an option to link PAN and Aadhaar with the different names using OTP, Gender and Date of Birth. But in the long-term, it is better to have the same name in both PAN and Aadhaar.

• Non-residents, those who are not citizens of India,
• People who are 80 years of age and over and
• People living in Assam, Jammu & Kashmir and Meghalaya

FAQs on linking of PAN and Aadhaar.
1) My total income is below Rs 2,50,000 a year, Do I still have to link my PAN card and Aadhaar card?
It is not compulsory for you to file income tax returns if your income is less than Rs. 2,50,000 per year. But you still need to link your PAN with your Aadhaar if you have been allotted as of July 1, 2017.
2) My name is different in the PAN and Aadhaar cards. What should I do?
First you have to decide which name you want to keep. If your Aadhaar card has the name which you want to keep, then you should change your name in PAN. However if your PAN has the desired name, then change it in Aadhaar card.
3) I do not have a PAN. What should I do?
You need not follow this requirement if you do not have a PAN. When you apply for a PAN in future, you should quote your Aadhaar number so that both IDs are linked.
4) I do not have an Aadhaar card. What should I do?
You should apply for the Aadhaar card as the government intends to make it a sole identity card.
5) Do NRIs have to link the two?
If you are an NRI and file tax returns in India, you can link the two though it is not mandatory. If you do not have an Aadhar card, you can apply for one.
6) I have linked my PAN and Aadhaar. How do I check that it is being reflected?
You will get a confirmation email informing that your PAN and Aadhaar are linked. If you login to the income tax portal, you will get the message – ‘Your Aadhaar is already linked with PAN’ and if your card is not linked then it will show “User ID does not exist”.

The government seems to have a plan of making Aadhaar as an identity card for every Indian citizen. Mapping it with the PAN is a way to eliminate fraudulent practices like one individual holding multiple PANs, tax evasion and money laundering. Let us support the government in their efforts to curb these actions.​
