This is exactly it. If you want my advice don't take the advice of people on here who don't really know what they're talking about. The laws governing taxes vary wildly from country to country and when you throw in bitcoin in complicates it even more as its such a new tech there usually arent any or many laws or regulations governing its use. If you want to use it to try avoiding taxes they you'll very likely open yourself up for trouble at a later date so be very careful and get some proper advice if you're seriously considering using bitcoin.
