which tax year do i file for?

What year must I choose if I do my tax return now

It depends what year you are filing for. If you are up to date with your tax affairs and want to file for the current year (i.e. 1 March 2015-28 Feb 2016) then you would select 2016 however filing for this year only opens 1 July 2016.

Tax filing season opens 1 July 2016! Please Register for TaxTim and let us assist you to complete and submit your tax return to SARS.
