Which Flagstone accounts accept US citizens

Last checked

Flagstone offers a savings account to a US person, with strings.

If you already have an account with Flagstone, a second one there is usually the easier application, because Flagstone has already checked who you are. Each account below carries its verdict, the evidence behind it and the date it was last updated.

US persons: nothing published about US persons either way, so ask before applying

A cash deposit platform rather than a bank: one application opens savings accounts across 65 or more banks, so a large balance can sit under several FSCS limits at once instead of one. Its published eligibility is UK residency, 18 or over, a UK bank account and £10,000, and nothing in its own material mentions US citizens, US persons or FATCA either way, so ask before applying. The cash waits in a holding account with HSBC while you choose, and Flagstone takes up to 0.30% of the interest rather than a platform fee. The US taxes the interest as ordinary income wherever the underlying account sits.

Tax

FATCA

FATCA makes UK banks report accounts held by US persons to the IRS. It is not a tax; it is a reporting trail. Where it bites is access.

FBAR

If your foreign accounts top $10,000 combined at any point in the year, you file an FBAR. What counts, when it is due, and what happens if you miss it.
