What most people do is to take straight forward deductions based upon the clear intent of the tax code.
Does this include the part where they falsify on their "Charitable Contributions"?
What Apple does is to make complex, bizarre money transfers and to employ convoluted business structures in order to skirt the clear intent of the tax code.
You've obviously never used 90% of the provisions in the US Individual Tax form, such as the deductions for energy efficiency (new windows, appliances, etc), or any of the depreciation provisions (which apply when you have capital assets under an LLC): it gets pretty complex pretty fast. Even just the proper documentation of retirement investments in a 401(k) ... which most gainfully employed heads of households now probably have ... is not a 1040EZ cake walk.
I said "most people"...
So you did. Unfortunately, "most people" aren't also in the top 10% of income to be a legitimate analogy: the mainstream equivalent would probably be something like a local small business.
For a coffee shop or deli, one of the very old business tax dodge tricks is to ring out the cash register a couple of times per day and neglect to report one of them on the books.
Another common small business tax dodge is the 'company car' and how it really gets used..."most" are quite creatively liberal with their mileage claims, as well as all of the service & repair bills, etc.
Similarly, "most" businesses have capital assets which involve the employment of the pretty damn convoluted depreciation deductions, as the US Tax code has several wrinkles in in that permit different methods (and "incentives")...oh, and as per my Accountant on my own convoluted out-of-State LLC, I apparently cannot not employ depreciation, either.
But to go back to individual taxes before closing out, have you ever checked the IRS Tax Code to see what the provisions are if you spend, say, 60% of your time outside of the USA, earning income in other countries? You might want to look, even if "most" people don't do this: it applies to everyone who is a multinational worker.
