Con to the question "Should Churches (Defined as Churches, Temples, Mosques, Synagogues, etc.) Remain Tax-Exempt?"
"The problem is that there are churches that are family businesses and where people are making a profit. You can have a church for profit, like any other, just like a shoe store. You can operate a church as a for-profit entity, and every year you should file returns with your profits and pay. These organizations think that by just registering as a non-profit organization they gain (automatic) rights to tax exemptions. They get incorporated and begin operations without ever requesting tax exemptions. They have spent years not paying taxes. Now they have to make retroactive payments."
