Under no circumstances contact the Inland Revenue.
They are very helpful people only in determining what you shall pay them. That is, after all, their duty, their job and their rationale. Once you have alerted them to your plans they will have you within their timetable which will not necessarily be the one that would suit your most efficacious tax planning schedule.
Contact a good accountant experienced in matters of residence, domicile and who is experienced in the field of overseas contracts and the tax implications thereof. Place all your affairs in his hands from scratch and let him deal with the tax men for you.
It is a matter of great incomprehension as to why pilots seem so averse to seeking professional information obtained on a paying basis.
If a good accountant saves you ten thousand in tax liability and sends you a bill for two thousand, he has saved you eight thousand and is thus surely worth the mustard? The only grit in this is that you have to pay him the fee whereas you will never have had to pay the tax. It's cheap at half the price, every time. Pay for the professional. Eat, drink and be merry thereafter!
