Need IRP5 from insolvent employer?

I want to get my IRP5 from previous employer for 2012 tax year, but that particular company has gone insolvent, so I have no way of getting relevant information for that period, What do I do?

You need to go to your local police station and swear an affidavit stating reasons why you are unable to obtain the IRP5. You could submit this to SARS together with any relevant information you may have proving your earnings for that year eg. bank statements, payslips, etc.
