We have HQ in Italy but most of our business comes through our US presence, so yes we report to the IRS...AND to the Italian taxman. We're a micro-multinational! :)

Hmmm that I didn't know. That could be complicated if they moved in the last year (e.g. deemed disposition of shares and all that). I guess as long as they're reporting to whoever the appropriate reporting authority is though I doubt Italy's tax department is as sophisticated as the IRS (they're known to have checked out facebook profiles).
