Obligatory quote from Judge Learned Hand:

"Anyone may arrange his affairs so that his taxes shall be as low as possible; he is not bound to choose that pattern which best pays the treasury. There is not even a patriotic duty to increase one's taxes. Over and over again the Courts have said that there is nothing sinister in so arranging affairs as to keep taxes as low as possible. Everyone does it, rich and poor alike and all do right, for nobody owes any public duty to pay more than the law demands."

I most people wouldn't your example tax avoidance. That deduction is meant for that particular situation and claiming it is to be expected. Exploiting some complicated loop-hole is something else entirely. That's what most people would label as tax avoidance.

You are making a distinction that doesn't exist. What you might consider a complicated loophole might be what every company with a CPA considers standard practice. Just because it's not obvious to a layman doesn't mean it's not the obvious standard operating procedure for corporate taxes. They are both "avoidance" in the same way, which is taking advantage of specific provisions that benefit that tax paying entity.

It's the same with the mortgage interest deduction. You avoid some level of taxes as a homeowner by deducting your mortgage interest. Until you have a house and need to do so, it may seem like some weird loop-hole in the taxes, and when you have a house and use it, it's just something you do every year.

Don't expect a multi-national company worth hundreds of millions or billions to view the tax system as being as opaque and complicated as it seems to an individual. Their situation is vastly more complicated than an individuals, and their capability to navigate the tax system is vastly higher as well with multiple CPAs on staff or a large firm hired, so they can take advantage of those provisions put into the system specifically for them.

That is effectively my point. It may be worth reassessing your perspectives if you are comfortable saying “when I use the tax code to my benefit, it is okay” but “when he uses the tax code to his benefit, it is not okay.” Fundamentally it is the same thing. The only difference is the scale. I’m open to arguments as to why this conclusion is correct, but it really seems like the classic case of hating on Big Corps because they are big, not because they are doing something bad (which they often do, but not in this case. To my mind).
