It is because of the PUBLIC benefit from charities that made governments to grant tax exemption to charities.
If you collected donations for a church auditorium, you must not use it to, say, send Pastor’s children to Harvard unless it is (1) clearly written in the church’s constitution that Pastors’ children would be sponsored to Harvard,
The charitable organization is tax exempted, the leaders of such organizations are not tax exempted.
I can be nice sometimes 😁😁😁
Your organization would pay the necessary taxes and you’ll keep all the “proceeds” to yourself.
Then, you avoid Section 839 and all the wahala. Hope that helps?
