CWF1 form

Hi everyone, I received a letter from HMRC , it stated that HMRC receive my form CWF1 , “ becoming self-employed and registering for National insurance contributions and / or tax”. My question is , I am not a self employed person, I have done 3 part times since arrived in UK last July , Also, I didn’t sent this form to HMRC. Why will it happen and what should I do now? I have web chat with the agent yesterday and he told me to ignore this letter and no need to do anything but I am still worrying about it and afraid of penalty. Regards,

Hi,
 

If you did not register for Self Employment, you should contact our Self Assessment department to review your record. See link: Self Assessment: general enquiries  . Thank you.

Hi, I have contacted the HMRC hotline last week and the customer service advisor told me to ignore this letter and she has not find record for my self employed. I am puzzled and still worrying about it even they told me to ignore it.
