In most cases, probably yes. But there are many reasons why it wouldn't be. Not so much here in the case of a video gaming message board website, but it could mean someone makes a ton of money and they don't want to risk messing it up and being audited. It could also mean someone is really busy (not to be confused with
lazy
which is better categorized under the topic title).
Basically if you make a lot of money and don't do your taxes, that's probably fine. If you don't make much money and don't do your taxes, then probably yeah, it's an intellect thing.
