Hi, I have received a self assessment statement from HMRC recently, stating I have to pay huge penalty from my previous statement, I'm employed to an organization and I don't think I have to pay self assessment as I don't fit with any category mentioned in https://www.gov.uk/check-if-you-need-tax-return I'm not sure if this is a scam, I tried to ring HMRC helpline, but couldn't get connected. I'm worried as I'm unable to understand the letter and not able to get enough help on this, any advise on this would be highly appreciated. Thanks in advance. Regards, Vinoth
