I emigrated from South african in 2016 to the United Kingdom.  I now need to inform SARS of my tax residency status change. write A letter of motivation to SARS setting out the facts and circumstances in detail to support the disclosure that I have ceased to be a tax resident

Notes:
- I do still have bank accounts in south africa but I don't earn any income in South africa and don't own any property there
- My Parents and siblings are still living there but i have no intentions to move back there permanently besides for family visits
