Do I need to fill out tax returns as a non-resident of South Africa? Left 8 years ago.

I am South African and for the past 8 years have lived abroad (UAE). I recently bought a holiday property in South Africa and thus found my tax number. Do I need to fill out tax returns? How do I declare medical aid and all those forms and numbers I am being asked for when I do not work or earn a salary in South Africa?

You don't have to submit a tax return if you have been outside of the country for longer than 3 years, this is acceptable to SARS.
