I just wanted to post an update with a more recent article with some extra information in it:
Romney's Tax
Mr. Romney’s 2010 returns also suggest he may have paid far less taxes the previous year. The 2010 return shows the family made estimated tax
payments for 2009 of $1,369,095. To avoid penalties, estimated tax payments must be at least 110 percent of the taxes owed the prior year. Assuming
that is what he paid, his federal tax bill for 2009 would have been $1,244,632, far less than in 2010. - NY Times
Man, it must be nice...
If he made $20 Million in 2009 and paid $1.2 Million in taxes... that's only around 5% tax...
