That would depend on their personal situation, but should they actually have a full financial life in another country including investments, pensions, mortgages, insurance policies, a small business, multiple bank accountsu2026The reporting alone can be bankrupting, and that is before you get on to actual taxes that are punitive toward foreign finances owned by a US citizen and god help you if you make mistake because penalties appear designed to bankrupt you.US citizens globally are renouncing citizenship for good reason.This is extracted from a letter sent by the James Bopp law firm to Chairman Mark Meadows of the subcommittee of government operations regarding the difficulty faced by US citizens who try to live else where.u201c FATCA is forcing Americans abroad into a set of circumstances where they must renounce their U.S. citizenship to survive.For example, suppose you have a married couple living in Washington DC. One works as a lobbyist for an NGO and has a defined benefits pensions. The other is self employed in a lobby firm, working under an LLC. According to the IRS filing requirements, it would take about 15 hours and $280 to complete their yearly filings. Should they under report income, any penalties would be a percentage of their unreported tax burden. The worst case is a 20% civil fraud penalty.Compare the same couple with one different fact. They moved to Australia because the NGO reassigned the wife to Sydney. The husband, likewise, moves his business overseas. They open a bank account, contribute to the mandatory Australian retirement fund, purchase a house with a mortgage and get a life insurance policy on both of them.These are now their new filing requirements:u2024 Form 8938u2024 Form 3520-Au2024 Form 3520u2024 Form 5471 (to be filed by the husbands new Australian corporation where he is self employed)u2024 Form 720 Excise Tax.u2024 FinCEN Form 114The burden that was 15 hours now goes up tou2024 57.2 hours for Form 720,u2024 54.20 hours for Form 3520,u2024 61.22 Hours for Form 3520-A.u2024 50 hours efor Form 5471For a total of 226.99 hours (according to the IRSu2019s own time estimates) not including time to file the FBAR.The penalties for innocent misfiling or non filings for the above foreign reporting forms for the couple are up to $50,000, per year. It is likely that the foreign income exclusion and foreign tax credit will negate any actual tax due to the IRS. So each year, there is a lurking $50,000 penalty for getting something technically wrong on a form, yet there would be no additional tax due to the US treasury.u201d
