Quilter Invest (formerly Wombat)

Skip

Formerly Wombat, then NuWealth, now Quilter Invest, and the US bar survived every rename. The platform is offered only to people who are 18 or over, UK resident and not a US person, and you warrant that on an ongoing basis and must tell Quilter immediately if it changes. It does offer US shares, which is what makes the bar sting.

Wombat Invest (now Quilter Invest)

Not offered

There is no Wombat account to open. Quilter bought the app in 2024, it became NuWealth that June and Quilter Invest in October 2025. The successor does run a general investment account, and its terms require that you are not a US person on an ongoing basis, with a duty to tell them immediately if that changes.

Confirm your own position with a cross-border specialist. Acceptance policies and tax rules change, and your facts may differ from the general case.

Tax

PFIC

Almost every UK-domiciled fund is a PFIC, taxed by the US at punitive rates with heavy filing. This is why US citizens hold individual shares, not UK funds.

 Tax

ISA US tax

The IRS does not recognise the ISA wrapper. Cash ISA interest and stocks ISA gains are taxable on your US return, and fund holdings drag in PFIC rules.

 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.
