Ideally you should include your latest address on your tax return as SARS would like to keep track of where you live. However this can prove difficult because if you change it online they may want proof of change of address. If you really want to be up to date then the next time you come to SA, go into a SARS office with a utility bill from your current foreign address. Until then it should be ok to keep the old address.
