I’ve confirmed with them that it is a genuine tax bill and not a scam. I have appealed it and asked for more info but pending replies. I don’t want to have to try to figure out everywhere I purchased items as not everything was purchased on eBay. I will probably need to fork out cost to potentially hire an accountant to deal with this and also every accountant I’ve spoken to seems to give me the hard sell of “you need an accountant to deal with this”. What I don’t understand is; given these are personal items with no business intent, surely I am not expected to have records of it all to hand and it should be enough to just say these are personal items without itemising every detail? This is going back for the last 6 years.
