Maybe if asked about it? They have no real idea which country I even live in, so they could either submit my data to _every_ tax authority on the planet and waste ressources for this or just deal with it like anyone else and have me submit my tax report on my own.

However it would definitely be much easier, if I were FINALLY able to get a full report about what happens on my account in CSV or any other format than a freakin' HTML table that does not even contain year numbers!
Manually doing this is no longer an option since I receive referral payments... For reference, my USD ledger is now close to 200 pages long.

Edit:
Congratulations on getting listed on http://bitcoincharts.com/markets/ finally by the way!
