When Tax Day Comes to Azeroth
1up is running a short piece originally from Games For Windows: The Official Magazine. It discusses the inevitability of taxation coming to virtual worlds, and a little bit about what that might mean in the indeterminate future: "Taxable income includes everything from tangibles like cookies to more ephemeral and subjective things like works of art, concert tickets, or advice. Those big, scary books that most sane people pay accountants to understand for them don't really narrow down what counts as taxable income so much as meticulously define it as damn near any piece of matter, energy, or information that should happen to pass into your possession over the course of the year. That goofy World of WarCraft gnome that GFW editor-in-chief Jeff Green's been leveling isn't any more intangible than, say, stocks."
Just show them your EULA.
Blizz claims ownership of the items, thus it would be illegal for them to tax you on something you don't own.
Remember, you licensed it, you don't own it.
Tax time in WOW is stupid and will never happen. OTOH, Tax time in second life is a possibility.
So, Blizzard owns your account. You own nothing, therefore, they'd have no reason to track sales. Now, a company like Linden, on the other hand, wouldn't have that loophole.
Build it, and they will come^Hplain.
