Does anyone know what the limit is?
If I brought £15,000 with me to the states, would I be liable for taxation on it?
I do not know what the limits are before you are required to declare (to U.S. Customs) the cash you are bringing in, but the Internal Revenue Service does not tax you on money you bring in to the country, no matter how much or little it is. The federal government (and some state and local governments) is interested, however, in the earnings on what you bring, and taxes you on those earnings.
