It's not every day that we get to find out the actual figures on how much celebrities earn in a year. Usually these numbers come from leaked legal documents like Zooey Deschanel's divorce papers, and they usually remind us just how astoundingly wealthy even B and C-list entertainers are. Leave it to world-class f-up Lindsay Lohan to buck the trend...

TMZ reports that Lindsay owes the IRS at least two years worth of back taxes and may not have paid any federal income tax since 2009. Needless to say, Linds is in serious debt to the government. What may be more shocking, however, is the fact that according to the IRS figures, Lindsay has only earned about $400,000 a year for several years in a row.

That may sound like a lot of money, but bear in mind the lifestyle that Lindsay leads and the amount of cash that she's raked in in the past. This is a girl who jets around the world partying with the Hollywood and fashion elite. She lives like a millionaire, despite the fact that her bank account hasn't showed seven figures since her Mean Girls days.

That said, 2011 was Lindsay's best year in a long time, even though she didn't land a single acting job. The tabloid queen parlayed the last of her fame into a $500,000 modeling gig for Phillip Plein, and reportedly earned close to a million dollars by stripping down for Playboy. That should help her begin to pay off her tax debt...which is rumored to be in the neighborhood of a quarter mil.
