Alright, I have looked over the form, I believe, and I had actually read several pages of that related thread before I asked my question, so i'll try and be more specific. Am I looking at the right form here? http://www.fincen.gov/forms/files/fin104_ctr.pdf . Just wondering since it refers to a transaction and I don't see how this scenario would be called that. Does this form just get sent to the IRS and then i'm expected to put it in my taxes that year? What if I have accumulated cash from my business but paid taxes on it over the years, and am leaving the country to retire? I want to know what the _effect_ on me of declaring the money will be. It's only $30,000, I _know_ how easy it would be to avoid all the hassle and hide it, but i'd like to know how big of a hassle this will really be for me in the long run to do it right. And again, i'm going to Thailand, I know it is pretty corrupt there and i'm pretty worried about declaring it on the way in there as well.
