If a foreign country's company or other organization that is not the US government asks if I'm a citizen of the US, am I required to state that I am?
I understand that any and all penalties that the foreign entity can enforce upon me for lying would be my responsibility, but I am a liable for anything under US law?
I was looking for a basic general answer to this under US law, but if you want a specific case here we go:
Expats have always been required to register any foreign 'bank account's that run a balance of over $10,000 in any given tax year. What the IRS calls a 'bank account' is at times a mystery. Regular checking and savings are of course bank accounts. But, sometimes pension accounts and even certain kinds of life insurance can be seen as bank accounts if certain conditions are met.
In 2010, Congress passed FATCA which took effect in 2014. This made it mandatory for foreign banks to report the balances on all accounts held by US citizens that exceed $50,000 or risk heavy penalties of 30% withholding on foreign exchanges. Most countries complied. What this means is that a bank, a foreign entity is basically forced to report full personal details as well as balances of anyone that meets those guidelines. This is a lot of extra work, so banks and other entities offering similar financial implements have started to reject US clients. Some expats that were caught unaware of these requirements have been slapped with massive penalties (50% of a year's balance). This has led to a spat of US citizens forfeiting citizenship and the US state department in turn making it more difficult and expensive to forfeit citizenship.
So, given the above situation. Couldn't one not disclose they were a citizen of the US considering the bank does not require one to do so to normally open an account?
Answering truthfully may mean the account is rejected or closed at a later date. Meaning that one might lose potential benefits or have to pay penalities with the bank or insurance company for early withdrawal. It could also mean one more account that the expat has to remember and report every year or face penalties.
