In 2017 the Indian government required taxpayers to link their PAN, the tax identity number, with Aadhaar, the national identity number. The deadlines in 2017 were July 31, August 31 and December 31. Then came March 31, 2018, and more dates after it. In 2021 the fact-checking site BoomLive called the latest move “the 11th such extension.”
In March 2023 the deadline moved once more, from March 31 to June 30, 2023. From July 1, 2023, the PAN of a taxpayer who had not linked it was to become inoperative.
