Do you have a journal entry of the affect of personal use company car (PUCC) in quickbooks I'm confused as to what happens when it hits the financials?

In the UK it depends on whether you're operating as a sole trade/partnership or a limited company. In a sole trade/partnership you should include the whole cost and then make an addback on a tax computation (hopefully something your accountant is doing). This addback is usually a % based amount. I do see some accounts where the addback has been made in the accounts themselves, this would be credit motor expenses, debit drawings. If you're operating a limited company then the information is a bit irrelevent for an accouting purpose but if there are vehicles with personal use then this triggers benefits in kind. I try to encourage most small limited company owners to own their own vehicles personally and claim business mileage instead, 45p for the first 10,000, 25p thereafter.
