1. The Overseas contract is ongoing i.e. no fixed time limit. I have been back to UK once (from 19-27 December 2013).
2. Both properties are now rented out (our pricipal residence has been rented out since Oct 2013).
3. Have not told the HMRC that I have left the UK as was not sure if things would work out in KSA i.e. might have come back eralier.
4. Tax has not been deducted by the agent as I plan to pay this when I submit my tax return.
I will do the needful with my managing agents. The contracts in Saudi are on a rolling basis. So renewal is done automatically. My first year finished on 1st September so my contract automatically renews for another year.
I plan to stay in Saudia Arabia for another 2 years i.e. till 1st October 2016.
