Dear experts,
in 2007, I spent more than 183 days in Massachusetts, U.S., and only had income in the U.S. For many years, I have been filing as the U.S. resident for many years, being in the U.S. between 1997 and 2007, and I plan to do it for 2007, my last year in the U.S., too. Most of my income tax in 2007 has been withdrawn.
But in Summer 2007, I also withdrew all funds from a TIAA-CREF account that was not taxed, but I provided TIAA with a W-8BEN form.
Now I am back in the Czech Republic and I plan to file as a U.S. resident for tax purposes for 2007. I suppose I will pay some tax from the TIAA-CREF money, maybe even the scary 30%. Could you please try to explain me what extra forms I need, where these amounts should be written, and how to calculate it (roughly)?
There are dozens of questions I would have to ask but I don't even know what are the right questions because the tax code always looks as a completely inpenetrable jungle to me. Similar questions apply to the Massachusetts state tax. Is the TIAA-CREF money taxed there and how? What forms do I need?
Best wishes Lubos
