The gummit ALWAYS wants their 'pound of flesh' and usually more it seems. In reality we are literally taxed to death in this country and Federal tax laws are very hard to interpret in the first place.
Never had the issues the OP discusses and don't want them either and why we retain a top tier accountant /CPA to handle that stuff for us. Money well spent in my view.
Far as I'm concerned, we should pay a simple flat tax and eliminate all the tax codes and complex rules and regulations.
In reality, in my opinion, there should be no taxes at all as the government is supposed to be here to help you, not relieve you of your money, not like they are at all fiscally responsible because they aren't and never have been that I can remember and it's getting worse and worse, not better.
My ongoing philosophy about government is...
They make no tangible product, they are the largest employer and they exhibit no fiscal responsibility in spending your money, simply because they didn't earn it in the first place.
I find it sadly amazing that politicians pizz away money like it's going out of style, especially this administration. Just the interest on the National debt is eating them up but they don't seem to care and why should they, it's not their money in the first place.
