The rich have never paid taxes. And it is not so much loopholes, or tax shelters, it is that they own businesses, they deduct their expenses from their income, and then pay taxes.
To the normal middle class person, they pay their taxes, and then pay their expenses.
The tax law is designed to destroy people. The Infernal Revue Syndicate are terrorists. That is the reason they exist.
They create more paper work than anyone could read each year. And you are supposed to follow it all. Further, they do not follow their own rules. Look up @larekenrose, he just released his giant book on his fight with said organization for free as a pdf.
I do suggest that you set yourself up as a corporation, and start doing deductions like a rich person.
