I believe Guya put a post on another thread ("Exchange rates for back taxes") about the automatic $10,000 penalty on failure to file information returns. I'm not aware of anything regarding increased reporting by the individual taxpayer.
My concern on HIRE has to do with the financial institutions requirements to file all the necessary paperwork for accounts defined as "US person accounts". The wording on the "Expanded Affiliated Groups" that constitute a single foreign institution is also interesting. If it becomes too onerous on the institutions, it may be more commercially advantageous for them to close all accounts over $50,000. But so far, I've read nothing regards this concern relating to the HIRE Act. If anyone is aware of potential problems, perhaps they could let us know.
