BTW that's true of income tax but not necessarily true of sales tax. Rules vary across the country but I've read about people getting in trouble for not remitting provincial sales taxes on garage sales. (There's no GST/HST issues since (a) "used goods" are generally exempt, and (b) almost everyone running a garage sale falls under the "small supplier" rules < $30k/year.)
