We have a small business with an accountant that deals with all our tax etc. We have just had a call from a court appointed bailiff saying that we owe £2000 to HMRC. He will send round bailiffs this afternoon to our accountants address as that is our registered address. Neither we nor the accountant are aware of any Corporation Tax, Income Tax or VAT that we owe and indeed our accountant has checked with all HMRC debt control and we do not owe anything. We have not received any letters asking for payment. Is this a scam?
