Income tax: what is the retention period for documentary evidence in relation to work-related expenses claimed by salary and wage earners?

The retention period for this documentary evidence is three and a half years from the date of lodgment of the tax return in which these expenses are claimed.

He will be required to keep records until April 1996 i.e. three and a half years from the date the return was lodged.
