> smaller entities simply can’t be bothered with the paperwork the US demands on accounts for “US Persons”
That only counts for companies with operations in the US. My wife is a US citizen, and my bank - a medium-sized Danish bank - did not care, because they don't operate any business in the US, so they do not need to provide any paperwork for her to US authorities.
Not an attorney, not a tax attorney, not your attorney, but US persons are required to report bank accounts they hold globally under both FBAR and FATCA, and signatory authority on business accounts is also a thing. Additionally, controlled foreign corporations are a thing for US people.
I'm also not a lawyer or CPA, but I believe if a US person is a partial owner in a foreign corporation, the company is required to do their accounting by GAAP standards. So, if the company is in a country that follows IFRS standards, it would have to do their books twice.
