UK Tax Questions? Ask a UK Tax Advisor for answers ASAP
Hello Chris, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
Firstly, when you left the UK in 2015 did you complete a Form P85 and send it to HMRC? If you did not then you should do so immediately, fortunately there is no time limit as to its submission, it is available on the web and can be filed on line. On receipt HMRC will classify you as non resident. Once so classified you can spend up to 91 days in the UK in any one tax year without breaching your non residential status. The number of trips to the UK is irrelevant, the 91 days is the key. On your return to the UK advise HMRC by letter and they will split the returning year in two portions, one non resident, the other resident. Your overseas earnings will not be subject to UK taxation under the P85 system.
I do hope that you have found my reply of assistance.
In theory the 91 days can be averaged out over four years, but the general consensus of expert opinion on this site is never to exceed the magic 91 days in any one tax year. The 180 days is nothing to do with the case.
Sorry to have to rain on your parade.
Please be so kind as to rate me before you leave the Just Answer site.
