Tax returns for 2007 needed

My tax have been submitted 13/8/2015 and they asked to supply a logbook which I did. My tax for 2014 was not done and have submitted those aswell. My 2015 tax was not being audited but my 2014 is under audit. When I log onto SARS eFiling it says my penalties are R500. I have called them now and they said ny penalties are R1500. And I have to submit my 2007 tax returns. I do not have any of those documents anymore as its 8 years back. How can I go about the difference in penalties fee's and submit tax that I do not have any details for? Please advise

You need to then submit a nil tax return for 2007, did you earn income and work during that tax year?

Yes I was employed, but the bussiness closed down, and I do not have any of those documents.

Should I submit as nill?

If you are unaware of the details then submit a nil, however go on SARS eFiling first and see if the IRP5 is preloaded? You will need to go to a police station and swear an affidavit stating you cannot get the old IRP5 and submit that to SARS if they ask.
