Quite @BobtheTrain.
I'm self-employed. My employer & I go to extreme lengths to define a contract that HMRC are satisfied produces the correct amount of tax. I neither have tax-sheltering offshore investments, nor a jet registered in the IoM. My company pays me, and its taxes, onshore.
Meanwhile, the facts on what HMRC collect and are defrauded out of by individuals are here:
They're closing the tax gap. Will
In that case why do you go through the artificial system of having your pay via a company and not simply become a direct employee. I was always under the impression that people gained tax / nic advantages being paid this way.
Do you not have a pension plan of some sort? If you do, you might be surprised by how many of the funds in it are sheltered by off shore locations. Often its Ireland which is just as much of a tax haven as Guernsey. I should add that I too have such investments. I just dont kid myself that they arent in a tax shelter.
