Just had a shock!
Its good that in Taxfiler (and prob other software I suppose... obviously dont know) you can click the button headed 'view HMRC data' and it tells you the info HMRC have on their computer
However, I just did so with one client and apparently he received a total of £389,400
Chance would be a fine thing..
He says he didnt receive anything and I can see from his business bank statements that he didnt - also can see from his CIS statements that he worked all through.
Isnt technology wonderful!
