I am a 49 year old UK citizen with a national health service pension and a private pension (SIPP). I am planning to emigrate to South Africa and (being married for 7 years to a South African Citizen) become a South African citizen. We plan to work and then retire in South Africa. As I will no longer be a UK resident my pensions will be paid gross of UK income tax. How will the lump sums and monthly payments be taxed in South Africa?
