I note that if you become a permanent resident in Cyprus you have to pay tax on all income, worldwide. Obviously the UK State Pension would be classed as income as it is in the UK as would bank interest, but is a War Pension and/or AFCS GIP taxable in Cyprus despite it not being so in the UK? Also, are service invaliding pensions taxable in Cyprus?
The current position is that you can choose to be taxed in UK or Cyprus - and you only get taxed once due to the double taxation agreement. The Pathfinder at link contains an article about living abroad generally.
