He's since published a broadside on his 2010 return, and a preliminary estimation on 2011. 2012 is, of course, a work in progress, as was 2008.
What you have to do is look at the first 3 years, and then the next 7 years, and you'd see he did not publish his returns for the years he probably suffered intense losses ~ just like the rest of us ~ to wit; 2007 and 2008!
Note, folks with 401(k) accounts probably noted the losses but they didn't have to pay taxes on them anyway!
If Romney followed the law and took every deduction available he got several million bucks back from the US Government for taxes paid in 2004, 2005 and 2006, and claimed some losses in 2007, 2008, 2009, 2010, 2011, and is going to claim some losses 2012 and 2013.
HIs problem consists of large dollar value REFUNDS and non payment of taxes at a high rate during periods when millions were losing their homes and retirement savings.
Although what he did was lawful, it will not set well ~ which is why he doesn't want to let you know about it.
The fault is in the tax code.
You are correct regarding the complexity. I can’t even imagine the level of complexity of a return for someone like him.
Not to mention, you would need to scrub them to black out private information such as dependent social security numbers, bank account numbers, private addresses, etc.
