When a UK resident talks about an ISA, a tax-free savings and investment account available to UK residents. Also known as Individual Savings Account, it lets you grow money without paying tax on interest, dividends, or capital gains. There’s no direct US version — the IRS doesn’t offer a single account with the same rules. But that doesn’t mean American citizens are left out. The real story isn’t about what’s missing — it’s about what’s already there, and how smart people use it.
Most US citizens who want tax-free growth rely on a combo of three tools: a Roth IRA, a retirement account where you pay taxes upfront and withdraw everything tax-free later. Also known as Roth Individual Retirement Account, it’s the closest thing to an ISA for long-term investing., a HSA, a health savings account that offers triple tax benefits: contributions are tax-deductible, growth is tax-free, and withdrawals for medical costs are tax-free. Also known as Health Savings Account, it’s not just for emergencies — it’s a stealth investment vehicle if you don’t spend the money right away., and a regular brokerage account, a taxable investment account where you can buy stocks, ETFs, and funds without contribution limits. Also known as non-retirement brokerage account, it’s flexible, with no withdrawal penalties, and you only pay taxes when you sell at a profit.. Together, they cover the same ground as an ISA — tax-free growth, flexibility, and control — but with more layers. You don’t need one account. You need a system.
Here’s what most people miss: the UK ISA is simple because it’s one box. The US system is complex because it’s multiple boxes you assemble yourself. A 30-year-old who maxes out their Roth IRA ($7,000 in 2025), contributes to an HSA ($4,150 for individual coverage), and adds $500 a month to a low-cost brokerage account isn’t just saving — they’re building a tax-free income stream that outperforms most ISAs. The difference isn’t in the account type. It’s in how you use them.
If you’re a US citizen wondering if you can get an ISA, the answer is no — but you don’t need one. The tools you already have are better suited to your tax system, your income, and your goals. The posts below show you exactly how to stack them up, when to use each one, and how to avoid the mistakes that cost people thousands in taxes. You’re not behind. You’re just using a different playbook.
US citizens can open an ISA if they're UK tax residents, but the IRS doesn't recognize it as tax-free. Learn why it often creates more tax problems than savings-and what to do instead.
