Sir, a number of my clients who possess a PAN Card are receiving the following SMS: Attention AXXXD KXXXR, Income Tax Department has received information about certain transactions reported by you in Form 60/61 relating to FY 2021-22. It is requested that if you are not in occupation of a PAN Number, the same may be applied in Form 49A immediately or else, the PAN Number should be submitted to the Reporting Entity within 15 days from the campaign execution date. - Income Tax Department
What steps should I take in response to this?
