Here’s one to try. I am a builder in California and generate more than a million dollars in profits. Easy with cost of housing here. I incorporate a new company in Nevada, “The Stick it to the Dumb California Legislators” (TSITTDCAL Corporation) I bid jobs and they supply the materials for the job(s). Say I can buy windows at Home Depot for $100. TSITTDCAL Corporation charges me $200 for the same window. Matter of fact gets them from the same HOME Depot. I might be a great builder but a lousy businessman. In effect I move the profit to a Nevada corporation out of the greedy sweaty palms of California and their beloved illegals.
That would be called a “loophole”, but it really isn’t. It’s called good navigation. There are many sandbars in the Mississippi; but a riverboat captain worth his salt learns to chart a new course each time the sands shift. No use running aground when there are ways to be found to go around the obstacles.
