I have a confession to make. We fell so hard for Antwerp, we started wondering whether, now or later (early retirement?), we could actually move there. For now, anyway, it is not to be, but if you are moving overseas...wanna buy a used tax guide?
International Living Bookstore sells this book called The Expatriate's Tax Bible. I bought it but now we don't need it and it's just sitting on the shelf...written by a lifelong IRS guy who knows his stuff, too.
You can buy mine on ebay...http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170166687007&ssPageName=ADME:L:LCA:US:1123
If life gives us another opportunity to consider an overseas move, I'm sure the tax code will have changed by then, so might as well sell this one while it's current!
