This is a paragraph from a VAT email recieved from HMRC:
Alternatively, if you use accounting software, in most cases you can use it to quickly prepare and submit your VAT return directly to HMRC.
An ex client of mine was shown how to use Xero he said it was simple and proceeded to input all his invoice and claimed VAT on everything and with his sales he just entered a few at random , apparently that what Xero told him to do . I told him the Return was incorrect and he said that I had recommended Xero - Xero had told him to claim VAT as per their system and checks where not needed . HMRC said software made VAT filing easy and aswas the software did the work . When I challenged him about the return being incorrecr he changed Accountants - I explained to the new Accountants why he changed and ex client threatened to sue me for defamation of his character . Is this a fair system ?
