> And that's why I continue to do all of my own tax filing, because, for me as a programmer, the US tax code is nothing more than the source code for a program written in its own language which happens to be a special dialect of English.

I try to do it myself as well, but when you get into various side hustles, you are faced with a number of problems:

1. Figuring out which tax forms you need.

2. Understanding the lingo in those forms.

Especially with item 2 above, I would likely have to read over a hundred pages (without exaggeration) to figure out how those terms relate to my side income. And that's after figuring out 1.

In any case, the purpose of the article is that most people I know implicitly trust their tax preparer, and they really shouldn't.
