I can think of folks who sell high $$ volume on eBay, but who don't have "Powerseller" status (i.e. they're qualified, but have never signed up for it). I wonder if CRA will be looking at ALL sellers who exceed some to-be-determined sales level (e.g. $1,000 per month or better). The initial message seems to be they'll identify those Powersellers who haven't declared any eBay income, and, depending on the success of that move, may progress to more detailed audits from there. One potentially awkward circumstance in the collectibles business is that much is bought and sold for cash. Proving your purchase cost on an item bought for cash at an antiques show or flea market or garage sale could prove challenging, as the only paper trail is a note you wrote saying the money was spent. I'm sure there'll be lots more forum comments on this one !! >>>>> Michael
