This year Penson (who clears for MBTrading) sent my 1099B for futures trading as PDF attachment via regular email with the non-descript filename of "Summary2009.pdf". I didn't even notice it until I contacted them to ask why I hadn't received the 1099B by (postal) mail like I had every previous year and they told me it was sent by email in January. I was stunned that they would send something that contains my name, address and social security info in the clear like that...even more bizarre that they didn't use the existing secure message system on their site (accessed over https). Anyway I replied to the Penson customer service person that I was unhappy about it and never got a response. So I contacted MBTrading and they said they would ensure a new procedure is implemented. Anyone else ever gotten a tax document emailed like that? Seems like a pretty serious lapse in judgment for a firm like Penson.
