Wow you’re getting some bad takes here. Having a phone number does not make you a US Person. Having a bank account there does not make you a US Person. I can only assume people are confusing this with the domiciled test that can exist in other tax jurisdictions. It’s mostly the same criteria as the usual tax resident status (so all citizens + those with work visas + if you’re in the country for 183 days).

HSBC had the most succinct summary I’ve seen: https://www.fatca.hsbc.com/-/media/fatca/pdfs/global---commo...

The Australian Tax Office has a reasonable guide on the overall scheme and how it applies: https://www.ato.gov.au/General/International-tax-agreements/...

Having a US phone number, bank account, company and a house does not make you a "US-Person". So why the banks ask you these questions?

The banks deal with FATCA with checkboxes. If you cross one incorrectly, I can imagine they need documentation for that. And no bank wants that.

I currently answer yes to all of those questions except owning property in the US. I am not deemed a US person. I carry no obligations or liabilities related to FACTA with my local tax office nor the IRS.

This is purely a procedural thing for a bank. If you qualify as a US Person then the bank is going to withhold additional tax on your accounts and you’ll have to get a rebate for any discrepancies you are owed when you file your returns. While I hate the whole process and think it’s a gross overreach by the US gov, it’s governance 101 stuff for a bank. If you’re dealing with a bank that is incapable of doing this I’d recommend finding different bank. This is like the “no brown m&ms” basic competency check in a band’s tour rider. If they’re not getting this right then who knows where else they’re incompetent.

Well the question is - will owning a share in a US entity make you a “US Person”?

My initial assumption that seems to be confirmed by HSBC and the ATO is “no”.

It will not. The entity itself however is a “US Entity”.

The issue isn't just whether you actually are a US Person; it's whether banks, etc., believe that you're not. Risk-averse institutions may just avoid doing business with anyone who seems like they might be, and can use whatever proxies they like to decide who they don't want to transact with.

The US doesn’t care if you live there or not (unlike every other country except China); you still have reporting requirements and technically have to file returns saying you don’t owe taxes.

My banks had me sign that my income is not from US. So owning a company in the US that I invoice or that pays dividends or something would not land well.

I recall that some of the questions mention that having US income is problematic, and that even having a US phone number is problematic.

But I'm not 100% sure.

Having certain ties to the US (such as a US phone number or regular transfers to or from a US account) are considered "US indicia". Having them triggers a requirement (thanks to FATCA) for the bank to verify your status as a non-US person. Usually this means furnishing a W-8BEN to the bank. This applies even if you're not a US citizen and never set foot in the US.

Even having a US phone number can signal that you are a potential "US person".
