Hello, I'm Keith and happy to help you with your question.
The first thing that you should do, if you have not done so already, is to complete a form P85 and send it to your tax office. Fortunately it is available, can be filed on line and there is no time limit. On receipt of the form HMRC will make you non resident for the tax year after your departure and furthermore split the leaving year into two portions, one resident and one non resident. As non resident this will leave the only income subject to tax that earned in the UK,
in your case, presumably as your question is unclear as to exactly to what rented property is owned by you or otherwise, or indeed where that property is located, your rental and investment income. You may see my problem, whose or where is it located? Your management income is not earned in the UK, the rental would be, ditto the investment income. As a non resident you are advised to spend no more than 91 days in each tax year in the UK to continue to retain your non resident status and no liability to UK income tax, save for that mentioned above.
I expect that you will have to come back to me to follow up. I suspect that you should not need to fill in an UK tax return at all unless your UK income is over the Personal Allowance limit of 10K..
Yes the income is over 10k and I did send a p85 when we left the UK in July 2010. My question is really just regarding the new questions associated with the new statutory residence test. That is should I write in the box the workdays I spend abroad even though these are on an informal personal basis - ie not for an employer or a formal company of my own?
