Thanks for the responses
Ok, thats great that gives me a feel for whats been happening wtih your movements to and from the UK, and its wonderful that you are feeling so well (I tend to think medication has much to do with creating additional physical and mental symptoms, but I am sure there are many GPs and consultants that would disagree with me - stating that the medicines are for the greater good!!
Ok, so what we ned to do is get you to complete form P85 - link here for this form which will advise HMRC that
1) You have left the UK to live and work - and have UK rental income - as the UK employment statted after this date - I would enclose a letter with this form dvisng the employment position too - so they can establish this income also (make sure that you advsiue you work online- and that all work is carrie don outside on the UK)
Link here form form P85
Let me know if you need the address to send this back to HMRC
2) Complete the claim for the Non Resident landlord scheme -

This will allow you to have the rental income paid gross to you - and then so that HMRc can keep an eye on your residency posistion, they will arrange for you to complete a self assesment tax return after each 5th April, for you to record your income from employment (less expenses) rental income (less expenses) and also detail the time you have spent in and out of the UK.and claim for your personal tax allowances (which you are entitled to regardless of whether you are resident or Not resident in the UK for tax purposes- as you are a British citize
IF you spend more than 90 days a year in the UK (and any of them for work purposes) then you will eemian as treated as a resident of the Uk and rem***** *****able to UK tax on your total income.
If that is the case, then as things stand the first £10,000 income is tax free and the remindr liable to 20% tax - and you will pay any tax due by the following 31 st Jan
So - your first tax return will be filled in for the 2014/2015 tax year - and ant tax due pais to HMRc by 31/01/2016.
Let me know if you have any follow up questions, OR need the address for HMRc to send back the P85 - but it would be appreciated if you could rate the level of service I have peovided, and note that you can always come back to Just Answwer when its time to fill in the tax return if you need any furtehr help-
