IRP5's

SARS are requesting IRP5's from me for 2006 & 2007 before they will release a refund for my current 2015 tax return. Problem is I don't have the IRP-5's anymore and neither does my employer. For what period are they supposed to keep it on their records? Please advise because I don't know what to do now.

You need to go to the police station and swear and affidavit stating you cannot find these IRP5's. Those we be acceptable by SARS.
