While Barack Obama and Joe Biden release their complete tax returns to the public once a year, Mayor Bloomberg makes journalists cram into a room and view his redacted returns for less than three hours—no photocopies. The Mayor says that it's because he fears "disclosing sensitive corporate information to his competitors," but it also probably has something to do with all the fun income streams and expenditures the Times found yesterday, including his $98K in equestrian winnings, and his $44K cabinets that were later donated to charity.
Unlike the mere mortals Bloomberg oversees, the mayor's tax documents don't display losses and income as pedestrian "dollar amounts," but as a "dollar range represented by letters." So "A" means $1K-$5K, whereas "G" is $500K-"to the moon," as the Times puts it. So we can only guess what Bloomberg made last year, other than to ballpark it at $4 million "at the very least." But to someone who's been valued at $18 billion, $4 million is couch change. Even less is the amount Bloomberg paid in taxes: $1.5 million. Keep those taxes on the wealthy down!
The Mayor was also charitable, forgiving a $500K loan to his alma mater Johns Hopkins (probably for that really sweet beerpong table they got last year), donating his daughter's old Jeep Grand Cherokee, and giving the $44K cabinets to "a charity that works with formerly homeless New Yorkers."
