Hi. First up, I’ll definitely contact a tax attorney with this but thought asking the Internet won’t hurt either. A numbskull idiot who has nothing to do with the United States (no citizenship, never a resident), not having once stepped foot on the US soil, has been investing with a US broker for the past 5 years or so. This idiot has a child, and the latter also has an account opened at a US brokerage and also has nothing to do with the United States. Throwing all caution to the wind, the idiot gifts a sum of money to their child by way of transferring it directly from their brokerage account to that of their child without even a slightest clue of potential tax implications in the United States. After a month or so, the idiot accidentally stumbles upon an article which in eloquent terms explains how f’d they are since transfers of cash between two non- resident aliens through American financial institutions are taxed in full amount without any right to use gargantuan life-time exemptions (which only apply to US residents). Mastering all 2 brain cells in their head, the idiot calculates that they basically owe IRS tens of thousands of dollars on the gift made. Henceforth, I will refer to myself in the usual manner. I’m at a loss of what to do. All the articles which I’ve found mostly state that such transfers are definitely taxed in the US. I’m so reluctant to do anything to attract attention from the IRS on the other hand, since I’ve also read that the chances of them finding out themselves are slim to none since they don't monitor NRA's at all. However, I’ve also read up on penalties for late filing and tax evasion and the situation can potentially get uglier by orders of magnitude. I’m sure the IRS won’t be contacting me and letting me know whether the tax is due or not. Therefore, I’m left with a simple choice-either contact them myself like a sucker with the question and incurring their taxing wrath, even though they might not have found out at all, or hold my tongue and pretend that nothing happened with the risk of having to be contacted by the IRS years later with huge penalties as a cherry on top. It is my choice to make, I do realise that, but what would you do/advise to do in such a case?
