Thanks Five Rings for your comments.
There is alot to consider here and I am under the assumption after reading the Brazil tax information that I will be hit with 25% taxes down in Brazil.
Also there is no tax treaty (as of yet) with Brazil and the US.

I have some time still ahead to prepare for this and negotiate with my company for different terms if needed.
Other information on the deal is that the company will give me a car while there and pay (reimburse) for moving expenses. I will take care of housing myself.
I am self-employed and hope to find someone to help me out with all this... From keeping up on estimated taxes and optimizing any tax breaks, its tough trying to figure this out alone.
Anyone know of someone well versed in US/Brazil expat tax advice?
Thanks!

First, and most importantly, download and carefully read Publication 54:

That will acquaint you with the rules dealing with the Foreign Earned Income Exclusion and the Housing Exclusion. You will be "Physically Present" rather than a "bona Fide resident."
See:
Foreign Earned Income Exclusion - Physical Presence Test
It is irrelevent where your salary is paid but I assume you will need some money to live on while you are in Brazil so you had best open a bank acccount there to get some of your money.
If you can rent your house by all means do. You will need to report that income on your US tax of course.
Keep careful track of your moving expenses as they are deductible if your company is not paying them.
For 2009 you may exclude $91,400 + the housing exclusion.

Be aware that Brazil has a very high social security tax and no tax or Social Security treaty with the US. For a little glimpse of their tax system read:
