The mining Companies and major Banks profits go to shareholders; Sanitarium profits go to third World developments, like hospitals, health Clinics and Schools.
Do you currently pay tax you give to registered charities? If you are not supporting Charities and Volunteer Organisations you are mean spirited and selfish. It is better to give the whole gifted amount to assist a person than to pay a tax on that gift.
I assume you believe if you give your children money that you prefer to also pay the tax on that. Brainless idea involving Governments in taxing Charity. Governments are there to assist in the running of a society not to govern society; That is a Totalitarian State.

Josephus,
how much does the CEO of Sanitarium get paid ?

I do not know, but he would pay relevant tax on his salary the same as any employee. Does such a question have any relevance to use of Sanitarium profits?

How much money individual do you give to charity?
10% of your income?
How much of it do you think you should give to general Government revenue?
These questions relate to the reality.

Josephus,
When your CEO earns less than I do then I'll give to your charity, as it stands I'm in more need than your outfit. If I donated $100 to a charity, how much would actually go to the needy ?
Besides I already give a third of my pay to a charity called ATO. That money then goes to keep bureau rats in better conditions than I'll ever experience.

Josephus, you may claim ALL the profits from the Sanitarium company go to third World developments, like hospitals, health Clinics and Schools.
Without transparency, you can claim that, I can just as easily claim NONE of the profits from the Sanitarium company go to third World developments, like hospitals, health Clinics and Schools.
At the moment their profits are treated as if what you say is true, 100% and they pay no tax. The little evidence of "good works" by churches show that only a very small percentage of revenue is in fact used for anything that could be construed as "good works".

Even if you put a dollar in you local churches 'Poor Box' you can't be sure it actually goes to the poor and isn't being spent on a porno video for the local priest, can you? There is no transparency!

Churches should pay tax and their land holdings should not be exempt from taxes, rates etc.

There should be no exemptions and all the charitable work that they do should be covered by Government welfare, end of story.
The Government might have to raise taxes but that's the level playing field.
