As mentioned in other comments - the tax deduction thing is not true. It is true, however, that they can '‘donate’ the funds to a charitable foundation that is run by the same people as the company (i.e. they are on the board of the charity as well as being C-suite execs of the company) thereby creating a slush fund disguised as charity that may only need to actually use 5% for charitable activities.

A national supermarket chain has its own foundation and sometimes runs fund rallies for it, which they collect through their store front.
What I stated comes from an explanation I was once given by an accountant. It works (or worked, hopefully) like that here, Portugal.
