The last date for linking the Permanent Account Number (PAN) to Aadhaar is tomorrow - March 31, 2021, otherwise the PAN card is likely to become invalid. If not linked, one may also be liable to pay a penalty of 1,000 as per the Finance Bill 2021. If you have still not linked your PAN card with the Aadhaar number, you can get it done by tomorrow. Last week, the government had passed the Finance Bill 2021, where it inserted a new section - '234H'. As per this section, a person will be liable to pay a late fee of up to 1,000 in case of non-linking of PAN number with Aadhaar.
