The Central Board of Direct Taxes (CBDT) has extended the deadline for linking PAN and Aadhaar by another one year till March 31, 2023. In addition to that, unlinked PAN will not be blocked and will remain operative. While that is the good news, the bad news is that those linking PAN and Aadhaar from April 1, 2022 will have to pay a fee for doing so. If you link the two sets of identity by March 31, 2022, the service is free.
