Even in the US, for most people tax filing it not really a complex process. It only gets complicated if you are trying to itemize deductions and have a complex income story. Most people can do it with a couple of documents and a single form.

It doesn't take a lot of 'complexity' in income to balloon up complexity. Any brokerage activity will generate quite a few additional forms for 1099-B, 1099-DIV, etc. Still not super complicated, but I keep seeing people discuss this as if you only have W2s and nothing else... which isn't usually true, especially for someone who is likely to be using OpenClaw.
