Your Roth crosses the border.
The tax break may not.
From the US side, your qualified Roth IRA distributions stay tax-free after you move — same rules as if you'd retired in Phoenix. The catch is your new country. Most US tax treaties were signed before Roth IRAs even existed, and most foreign tax authorities don't honor the tax-free character that defines the account.
Translation: an account that's tax-free in the US can become one of your highest-taxed income streams abroad. Here's how to think about it before you book the move.

The treaties pre-date
the Roth IRA.
The Roth IRA was created by the Taxpayer Relief Act of 1997. Most US bilateral tax treaties were negotiated long before that — the US-Italy convention in 1999 (with roots in a 1984 predecessor), the US-Greece treaty all the way back in 1950. The pension articles in those treaties were written for traditional defined-benefit pensions and tax-deferred accounts. They don't mention Roth, because Roth didn't exist yet.
That gap is what creates the problem. Your country of residence decides how to tax your worldwide income. Without explicit treaty language protecting Roth's tax-free character, most countries default to their own pension or income rules — and treat the distribution like any other taxable income.
The US side never changes.
Qualified Roth distributions remain tax-free to the US whether you live in Boise or Bali. That's US tax law — it doesn't bend based on residence. What changes is whether your new country respects that treatment, and most don't.
Every country falls
into one of three buckets.
Once you know which bucket your destination sits in, you can model the tax cost in about ten minutes.
Respects the Roth
The country recognizes Roth's tax-free character and doesn't tax qualified distributions. This is rare. France and Belgium have historically been favorable on this point — but treaty interpretation can shift, and we haven't independently verified current treatment for either.
Best case — you get the same tax-free benefit you'd get stateside. Verify with a cross-border CPA for your specific destination.
Pension-annuity split
The country treats Roth as a pension or annuity. Return of contributions (your basis) isn't taxed; investment growth is taxed as pension income. Portugal works this way under its IFICI regime.
Middle case — partial protection, but documentation matters.
Taxed as ordinary income
The country doesn't recognize Roth's special status at all. Distributions are taxed at the country's standard rates, sometimes including the contributions you already paid US tax on. This is the most common pattern. Italy and Greece both follow it.
Worst case — the tax-free account becomes one of your highest-taxed income streams.
Special tax regimes complicate this. Some countries (Italy, Greece, Portugal) offer flat-rate programs for new resident retirees that override the standard rules — covering Roth distributions at the regime's flat rate (7%, 10%) instead of standard progressive rates. That softens the bite, but doesn't restore Roth's tax-free character.
The big three for US retirees.
Each country page has the full breakdown — visa rules, healthcare, the works. The summaries below cover just the Roth treatment and what it means for your planning.
Pension-annuity split
Portugal does NOT recognize Roth's tax-free status, but treats the account as a pension annuity. Return of contributions isn't taxed; growth is taxed as pension income.
Under the IFICI regime (NHR's successor), pension income is taxed at 10% flat for 10 years — including Roth growth. Outside the regime, standard progressive rates apply.
Portugal full guide → Greece · Pattern 03Ordinary income (or 7% flat)
Greece doesn't recognize Roth's tax-free status. Standard rates run 9%–44%.
The pensioner regime applies 7% flat to all foreign-source income for 15 years — including Roth distributions, dividends, and capital gains. You typically need US Social Security or 401(k) income to qualify the regime; standalone Roth may not be enough.
Greece full guide → Italy · Pattern 03Ordinary income (or 7% flat)
Italy doesn't recognize Roth's tax-free status. Standard IRPEF rates run 23%–43% plus surtaxes.
The 7% flat tax for foreign pensioners (qualifying southern towns under 30,000 residents) covers Roth at 7% flat for 10 years — once you qualify the regime via other pension income. Roth alone usually doesn't meet the eligibility bar.

We're working through additional retirement destinations — Spain, France, Mexico, Costa Rica, Panama, and more. Each country guide will include a Retirement Account Treatment section, with Roth handling spelled out. If your destination isn't here yet, the three patterns above will give you the right questions to ask a cross-border CPA.
Convert before
you become a resident.
Here's the thing: the country can only tax distributions after you become a tax resident. If you have a meaningful Traditional IRA or 401(k) balance and you're moving somewhere that taxes Roth as ordinary income, converting to Roth before you establish foreign tax residency can lock in the US tax treatment.
You'll pay US tax on the conversion in the year you do it — which is the same tax you'd eventually owe on traditional IRA distributions anyway. The difference: those funds, once Roth-converted, may escape the foreign tax authority's notice depending on how their rules treat pre-residency Roth balances vs. post-residency contributions.
The window closes the day you become a tax resident. Plan the conversion in the calendar year before you go.
This is one of the most underused moves in expat retirement planning. It only works if you do it before your residency clock starts — once you're a tax resident, the conversion itself becomes taxable in your new country at potentially much higher rates.
Don't DIY this one.
Roth conversions interact with Medicare IRMAA brackets, Social Security taxation, your state's residency rules, and the timing of your foreign move. The math can shift by tens of thousands of dollars depending on the year you convert. This is the kind of decision worth paying a cross-border specialist for — not the kind to read about and execute alone.

A typical cross-border return at TFX runs $450 federal (Form 1116 included) plus $85 if you need an FBAR. They handle the treaty positions and pre-residency conversion timing that determine whether your Roth survives the move intact.
