Retirement Account Tax Treatment by Country
How 26 countries treat Roth IRA, Traditional IRA/401(k), and Social Security income for US retirees who become tax residents there. Every claim is labeled by confidence — Settled means documented and consistent across sources, Contested means tax authorities haven't ruled and professional opinion is divided, and Unclear means no authoritative source directly addresses it. This is not tax advice — see each country's full page for sources and a recommended advisor type.
Most US tax treaties were written decades before the Roth IRA existed — it wasn't created until 1997, and most treaties predate that or were never updated to address it specifically. That's why whether a given country respects the Roth's US tax-free status is often genuinely unresolved, not a settled legal question with one right answer.
Where a claim below is Contested or Unclear, we say so explicitly rather than picking the more optimistic interpretation and presenting it as settled. Country-specific tax planning at this level of complexity shouldn't be attempted from a website alone — it should be developed with a cross-border tax specialist current on both the US side and the specific country's domestic law. This page exists to help you show up to that conversation with better questions, not to replace it.
Argentina
Roth IRA Unclear
No authoritative source directly addresses Roth characterization. Genuinely unresolved rather than contested — insufficient public guidance exists either way.
Traditional IRA / 401(k) / Pension Unclear
Argentina taxes worldwide income for tax residents (5-35% progressive) but 'Pensionado status does not create a blanket tax exemption... should be reviewed case-by-case with a tax professional' per specialist source.
Social Security
Not specifically confirmed by any source reviewed; no treaty exists to provide a baseline answer.
Key consideration: No treaty, no totalization agreement, and genuine lack of public guidance on account-specific treatment. Requires more individualized professional research than any other country in this guide. Argentina's history of rapid tax policy changes compounds this.
Recommended advisor: Argentina-specific tax professional with direct current experience filing Argentine returns for US retirees with IRA/401k income

Roth IRA Settled
Belize does not tax foreign-source income under any circumstances, including Roth IRA distributions.
Traditional IRA / 401(k) / Pension Settled
Same unconditional territorial exemption applies to Traditional IRA/401(k) and pension distributions.
Social Security
Not taxed, under the same blanket foreign-income exemption.
Key consideration: Belize's exemption is unconditional, no multi-year sunset or income cap.
Recommended advisor: Standard US expat tax CPA.

Roth IRA Contested
Chile does not tax foreign-source pension or investment income for residents under current published guidance; this appears to extend to Roth distributions, though Chile has no Roth-equivalent account type and hasn't issued Roth-specific guidance.
Traditional IRA / 401(k) / Pension Contested
Foreign pension and retirement account distributions are treated as foreign-source income and not taxed by Chile for residents under current guidance.
Social Security
Explicitly exempt — foreign pension and Social Security income are not subject to Chilean tax regardless of residency status.
Key consideration: New tax residents also get an automatic 3-year exemption from worldwide taxation (extendable to 6), layered on top of the general foreign-pension exemption.
Recommended advisor: Cross-border CPA familiar with Chile's 2024 treaty and territorial exemption rules.
Read the full Chile profile →Colombia
Roth IRA Unclear
Genuinely disputed. Some sources report a 2023 law exempting foreign pensions from Colombian tax up to roughly $10,000/year; others find no such exemption confirmed against DIAN guidance, and one preparer states Colombia doesn't recognize US retirement account tax benefits at all.
Traditional IRA / 401(k) / Pension Unclear
Same dispute applies — some sources describe a partial foreign-pension exemption, others report full worldwide taxation of IRA/401(k) distributions with no special treatment.
Social Security
May fall under the same disputed foreign-pension exemption, not independently confirmed.
Key consideration: One of the least-settled countries on this list. Get a current, written opinion from a Colombia-based advisor before assuming any exemption applies.
Recommended advisor: Colombia-based contador with direct DIAN experience, alongside a US-side cross-border CPA.
Read the full Colombia profile →Costa Rica
Roth IRA Settled
Not taxed by Costa Rica — territorial system exempts all foreign-source income.
Traditional IRA / 401(k) / Pension Settled
Not taxed by Costa Rica, same territorial-system reasoning.
Social Security
Not taxed by Costa Rica; up to 85% remains includable in US taxable income regardless.
Key consideration: Must be able to document income as genuinely foreign-source (contracts, payment records). Trivial for standard retirement income; more relevant with mixed income streams or local work.
Recommended advisor: US-side CPA or enrolled agent; Costa Rica-side complexity is minimal for pure foreign-source retirees
Read the full Costa Rica profile →Croatia
Roth IRA Unclear
No country-specific source identified addressing Roth IRA treatment. Genuine research gap, not a confirmed answer either direction.
Traditional IRA / 401(k) / Pension Unclear
US tax treaty confirmed in force, but specific application to IRA/401k income not addressed in sources reviewed.
Social Security
Not specifically confirmed by any source reviewed.
Key consideration: Genuine research gap — requires direct professional research rather than relying on any general assumption, favorable or unfavorable.
Recommended advisor: Croatia-specific cross-border tax specialist or treaty-network specialist to review the pension article of the US-Croatia treaty directly
Read the full Croatia profile →Cyprus
Roth IRA Contested
Under standard residency, explicitly described as unresolved — 'complex and varies.' Treaty savings clause and separate Cyprus taxing rights both apply, reconciled via credits rather than exemption.
Traditional IRA / 401(k) / Pension Contested
Under standard residency: contested, treaty allocation may give Cyprus taxing rights alongside the US. Under Cyprus Non-Dom regime specifically: foreign pensions described as 'largely exempt.'
Social Security
Taxable only in US under treaty savings clause, but Cyprus 'may also tax as worldwide income' per one source — confirm directly.
Key consideration: Choice between standard tax residency (treaty-based, contested) and the Non-Dom regime (explicitly favorable for foreign pensions) is the most consequential decision.
Recommended advisor: Cyprus-specific cross-border tax specialist to confirm Non-Dom eligibility and account treatment
Read the full Cyprus profile →Czech Republic
Roth IRA Unclear
No Czech-specific guidance found. The Czech Republic taxes residents on worldwide income; without a domestic Roth-equivalent concept, distributions are more likely treated as ordinary taxable income than tax-free, though unconfirmed against Czech tax authority guidance.
Traditional IRA / 401(k) / Pension Unclear
Likely taxed as ordinary income upon distribution, consistent with worldwide taxation of residents — not confirmed against Czech-specific guidance.
Social Security
The treaty likely assigns specific taxing rights via its pension/social security article, not independently confirmed here.
Key consideration: One of the least-documented countries on this list for retirement-account-specific treatment. Budget for a real consultation rather than general expat-tax content.
Recommended advisor: Czech daňový poradce with cross-border US experience.
Read the full Czech Republic profile →Dominican Republic
Roth IRA Unclear
The DR offers a widely-cited 3-year tax holiday on foreign income for new residents; afterward it moves to a semi-territorial system, though sources vary on exactly what becomes taxable at that point. Roth-specific treatment isn't independently confirmed.
Traditional IRA / 401(k) / Pension Unclear
Same 3-year holiday applies to foreign-source retirement distributions; treatment after the holiday period is less consistently described across sources.
Social Security
Likely covered under the same foreign-income holiday/semi-territorial framework, not independently confirmed.
Key consideration: The 3-year new-resident holiday is well-documented; what happens in year 4 onward is where sources disagree.
Recommended advisor: DR-based tax attorney (abogado) experienced with foreign retirees' post-holiday tax position.
Read the full Dominican Republic profile →Ecuador
Roth IRA Settled
Not taxed by Ecuador — territorial system exempts foreign-source income, consistent with Traditional accounts.
Traditional IRA / 401(k) / Pension Settled
Generally exempt under territorial system, similar to Panama/Costa Rica. However, one detailed source shows retirees actually filing and owing modest amounts (~$400-600/year on $22,800 SS) before an over-65 deduction (~$23,444 in 2026) typically zeroes it out — more filing formality than Panama's approach.
Social Security
Not taxed by Ecuador; SSA International Direct Deposit wires benefits directly with no Ecuadorian tax on transfer.
Key consideration: Plan to actually file an Ecuadorian return and claim the over-65 deduction explicitly rather than assuming automatic exemption like Panama. Confirm whether holding a residency visa triggers a tax-residency presumption regardless of days spent in-country.
Recommended advisor: US-side CPA or enrolled agent with specific Ecuador experience
Read the full Ecuador profile →Estonia
Roth IRA Unclear
No Estonia-specific guidance found. Estonia taxes residents on worldwide income; without a domestic Roth-equivalent concept, distributions are more likely treated as ordinary taxable income than tax-free, though unconfirmed against Estonian tax authority guidance.
Traditional IRA / 401(k) / Pension Unclear
Likely taxed as ordinary income on distribution, consistent with worldwide taxation of residents — not confirmed against Estonia-specific guidance.
Social Security
The treaty likely addresses this via its pension/social security article, not independently confirmed here.
Key consideration: Very little published guidance exists on US retirement account treatment specifically — genuinely underexplored territory.
Recommended advisor: Estonian maksunõustaja with cross-border US experience, or a US-side cross-border CPA experienced with Baltic countries.
Read the full Estonia profile →France
Roth IRA Contested
Genuinely unresolved. Some advisors argue a 2009 treaty protocol amendment brings Roth IRAs within Article 18's protective scope; others recommend declaring distributions and seeking case-by-case treaty relief.
Traditional IRA / 401(k) / Pension Contested
Two named professional sources reach opposite conclusions on Article 18: one says the US has exclusive taxing rights (source-country); another says France has exclusive taxing rights as 'standard OECD pension treatment' (residence-country). This is the most contested single question in this entire guide.
Social Security
Taxed exclusively by the US as the paying state — the one point of clear agreement across sources.
Key consideration: Given the genuine unresolved disagreement over which country has primary taxing rights on Traditional IRA/401k distributions, get a specific written opinion before relying on either interpretation — the financial difference is not small. Separately, French social charges (CSG/CRDS, ~17.2%) on investment income are not treaty-covered or creditable.
Recommended advisor: Cross-border tax specialist licensed in both US and France, asked to directly address the Article 18 source-vs-residence disagreement
Read the full France profile →Greece
Roth IRA Settled
May be taxed as ordinary income despite US tax-free status; Greece does not automatically recognize Roth's unique character.
Traditional IRA / 401(k) / Pension Settled
Explicitly covered by the 7% flat-tax regime for qualifying pensioners (up to 15 years), subject to documentation showing the account relates to past employment. Standard progressive rates otherwise apply (9-44%).
Social Security
Sources list Social Security among income types covered by the 7% flat rate itself, differing structurally from Italy where SS is US-exclusive. Confirm directly.
Key consideration: 15-year regime duration is the longest reviewed in this guide, with no small-town residency requirement unlike Italy. Confirm Social Security treatment specifically, since it appears to fall under the 7% rate rather than being US-exclusive.
Recommended advisor: Greece-specific cross-border tax specialist to confirm both account qualification and Social Security treatment
Read the full Greece profile →Italy
Roth IRA Contested
Not tax-free under standard rules. Whether a Roth qualifies as 'pension income' for the 7% flat-tax regime is genuinely uncertain and case-specific.
Traditional IRA / 401(k) / Pension Contested
Taxed as ordinary income under standard rules (up to ~43%). Under the 7% flat-tax regime for qualifying pensioners relocating to small southern municipalities (population up to 30,000 as of April 2026), same income taxed at just 7% for up to 10 years — IF the account qualifies as pension income, which requires confirmation.
Social Security
Taxed exclusively by the US under treaty, confirmed by professional forum guidance; not taxed by Italy under either regime.
Key consideration: Confirm 7%-regime eligibility for specific account types before moving — the gap between 7% and standard progressive rates (up to ~43%) is enormous. Roth-heavy retirees should consider restructuring before residency given the account-qualification uncertainty.
Recommended advisor: Cross-border tax specialist with specific experience confirming 7%-regime qualification for self-directed US retirement accounts
Read the full Italy profile →Malaysia
Roth IRA Contested
Malaysia has generally exempted foreign-source income remitted by tax residents, including under the MM2H program, which would extend to Roth IRA distributions — but Malaysia has debated narrowing this exemption in recent years.
Traditional IRA / 401(k) / Pension Contested
Same foreign-source exemption framework applies to Traditional IRA/401(k) distributions under current rules.
Social Security
Falls under the same general foreign-source income exemption as other retirement distributions.
Key consideration: Malaysia's foreign-income exemption has been narrowed before and is periodically discussed politically — not a permanent guarantee like Panama's or Belize's territorial systems.
Recommended advisor: Malaysian tax agent familiar with MM2H visa holders' foreign-income treatment.
Read the full Malaysia profile →Malta
Roth IRA Unclear
Appears on a general comparative list as 'favorable' alongside the UK — but the UK is directly contradicted by more detailed research (HMRC does not recognize Roth status), casting doubt on the list's reliability. No Malta-specific detailed source found.
Traditional IRA / 401(k) / Pension Unclear
Not specifically addressed in sources reviewed. Malta's Non-Dom remittance-basis system (foreign income taxed only if remitted) may be relevant but requires direct confirmation for retirement accounts specifically.
Social Security
Not confirmed by any source reviewed.
Key consideration: Malta's general 'tax-friendly for retirees' reputation is not the same as confirmed retirement-account treatment — the gap between reputation and confirmed specifics is the widest of any country in this guide.
Recommended advisor: Malta-specific cross-border tax specialist, explicitly asked to address Roth and Traditional IRA treatment directly
Read the full Malta profile →Mexico
Roth IRA Unclear
No authoritative source directly confirms treatment. One general source suggests the treaty 'generally recognizes' tax-deferred character, but this is not corroborated by specialist cross-border firms.
Traditional IRA / 401(k) / Pension Contested
Depends on actual tax residency status under Mexican domestic law ('center of vital interests' test), not visa type. Temporary residents/non-tax-residents: generally untaxed. Genuine tax residents: taxable under Article 19, with US FTC available.
Social Security
Taxable only by the US under Treaty Article 19(1)(b), regardless of Mexican residency status.
Key consideration: Determining actual Mexican tax residency status (vs. simply holding a residency visa) is the single most important factor and changes the answer materially.
Recommended advisor: Cross-border tax specialist who can assess 'center of vital interests' facts under Mexican domestic law
Read the full Mexico profile →Netherlands
Roth IRA Contested
Genuinely disputed in practice. Some tax advisors and treaty readings hold that Roth payouts aren't taxed as Dutch income (since already taxed pre-contribution in the US); however, real cases — including informal Belastingdienst opinions reported by expats — have sometimes taxed a portion of Roth withdrawals and/or applied Box 3 wealth tax to the account balance annually. Outcomes have varied case by case.
Traditional IRA / 401(k) / Pension Settled
Taxed by the Netherlands as ordinary pension income (Box 1) upon distribution, per the US-Netherlands treaty; the undistributed account balance is not subject to Box 3 wealth tax.
Social Security
Exempt from Dutch tax — taxable only by the US under the treaty, though still reportable to Dutch authorities for context.
Key consideration: The Roth IRA Box 3 question is unsettled enough that some expats have obtained written Belastingdienst opinions specifically for their situation.
Recommended advisor: Dual-qualified US/Dutch cross-border tax advisor with direct experience obtaining Belastingdienst rulings on Roth accounts.
Read the full Netherlands profile →Panama
Roth IRA Settled
Not taxed by Panama — territorial system exempts all foreign-source income regardless of type or amount.
Traditional IRA / 401(k) / Pension Settled
Not taxed by Panama, same territorial-system reasoning as Roth.
Social Security
Not taxed by Panama.
Key consideration: No local-rate-minimization question exists since Panama taxes none of this income. FEIE only shelters earned income, not retirement distributions — most retirees rely on standard 1040 filing rather than treaty provisions.
Recommended advisor: US-side CPA or enrolled agent experienced with expat filings
Read the full Panama profile →Philippines
Roth IRA Unclear
No country-specific source directly addresses Roth characterization, though the SRRV program's general foreign-source exemption is a favorable signal worth confirming for this specific account type.
Traditional IRA / 401(k) / Pension Unclear
US tax treaty in force. SRRV visa holders benefit from a foreign-source income exemption per this site's Philippines profile, which likely extends to retirement account distributions but requires direct confirmation.
Social Security
Not specifically confirmed by any source reviewed.
Key consideration: The SRRV foreign-source income exemption is the most favorable signal available but is a visa-program provision, not a confirmed direct answer for Roth/Traditional IRA characterization specifically.
Recommended advisor: Philippines-specific cross-border tax specialist familiar with SRRV holders' filing patterns
Read the full Philippines profile →Portugal
Roth IRA Settled
Not recognized as tax-free. Contributions exempt under Article 54; growth taxed as pension income at progressive rates (12.5-48% + up to 5% solidarity surtax).
Traditional IRA / 401(k) / Pension Settled
Taxed at standard progressive rates under Treaty Article 20(1)(a) once resident. Article 25 FTC prevents double taxation.
Social Security
US retains taxing rights as the paying state under Article 20.
Key consideration: NHR (flat 10% pension rate) closed to new applicants Jan 1, 2024. IFICI replacement excludes pension income entirely. Consider converting to Roth before establishing residency given no local Roth benefit either way.
Recommended advisor: Cross-border tax specialist familiar with post-NHR standard regime
Read the full Portugal profile →Slovenia
Roth IRA Unclear
No country-specific source identified addressing Roth IRA treatment. Genuine research gap.
Traditional IRA / 401(k) / Pension Unclear
US tax treaty confirmed in force, but specific application to IRA/401k income not addressed in sources reviewed.
Social Security
Not specifically confirmed by any source reviewed.
Key consideration: Genuine research gap, similar to Croatia. Don't infer favorable treatment from Slovenia's low capital-gains-tax reputation — that's a separate question from retirement account characterization.
Recommended advisor: Slovenia-specific cross-border tax specialist or treaty-network specialist to review the pension article of the US-Slovenia treaty directly
Read the full Slovenia profile →Spain
Roth IRA Contested
Not recognized as tax-free. Contributions exempt; growth taxed as savings income (~19-30%), though some advisors argue full ordinary-income treatment (up to 45-47%) applies instead.
Traditional IRA / 401(k) / Pension Settled
Taxed as savings/general income once Spanish tax resident. Treaty FTC (Article 24) prevents true double taxation with the US.
Social Security
Addressed under treaty; saving clause preserves significant US taxing rights over its citizens regardless of residence.
Key consideration: Consider Roth conversion/liquidation timing relative to establishing 183-day tax residency, given the unresolved DGT position on Roth growth.
Recommended advisor: Cross-border tax specialist licensed in both US and Spain
Read the full Spain profile →Thailand
Roth IRA Unclear
Not directly addressed by any source reviewed. Tax only triggers on remittance, giving a distinct planning lever — avoid remitting Roth withdrawals into Thailand.
Traditional IRA / 401(k) / Pension Settled
US Treasury Technical Explanation explicitly lists 401k/Traditional IRA/SEP/SIMPLE as 'pensions' under Treaty Article 20(1) — taxable only by Thailand if resident AND remitted.
Social Security
Taxable only by the US under the treaty, regardless of remittance.
Key consideration: 2024 rule change (Por.161/2566) closed the old 'wait a year, remit tax-free' loophole — all income earned from 2024 onward is taxable whenever remitted. Managing what counts as a remittance (transfers, ATM withdrawals, card payments) matters more than account type.
Recommended advisor: Thailand-specific cross-border tax specialist current on post-2024 remittance rules
Read the full Thailand profile →Uruguay
Roth IRA Contested
New residents can elect an 11-year exemption from tax on all foreign-source income, or a permanent 7% flat-rate alternative instead — this would cover Roth IRA distributions during the exemption window. Treatment after the 11-year window isn't consistently addressed across sources.
Traditional IRA / 401(k) / Pension Contested
Same 11-year exemption (or 7% flat-rate alternative) applies to Traditional IRA/401(k) distributions during the election period.
Social Security
Falls under the same election; several sources describe Uruguay's system as largely source-based, treating most foreign pension income favorably even outside the formal exemption window.
Key consideration: The choice between the 11-year full exemption and the permanent 7% flat rate is a real, one-time strategic decision — get advice on this before or shortly after establishing residency.
Recommended advisor: Uruguay-based contador experienced with the foreign-resident exemption election, alongside a US-side cross-border CPA.
Read the full Uruguay profile →Vietnam
Roth IRA Contested
No official guidance exists. Vietnam's tax code has no concept matching the Roth's tax-free structure; at least one specialist US-expat tax firm expects Vietnam to tax Roth distributions as ordinary income for tax residents.
Traditional IRA / 401(k) / Pension Contested
No specific exemption identified. Expected to be taxed as ordinary income for Vietnamese tax residents under the general worldwide-income rule — the account type most exposed to real double taxation here.
Social Security
Vietnam exempts "retirement pensions paid under the SI law (or the foreign equivalent)" — whether US Social Security qualifies as a foreign equivalent is unconfirmed. Regardless, the US still taxes up to 85% of benefits with no treaty relief.
Key consideration: The highest-friction country in this guide for US retirement accounts: worldwide taxation, no treaty, no settled guidance. Most current retirees stay under the 183-day residency threshold rather than test actual treatment as a confirmed tax resident.
Recommended advisor: A cross-border tax specialist with direct Vietnam PIT experience, ideally one who has handled a US retirement-account distribution for a Vietnamese tax resident.
