Overview
Greece offers a similar-in-spirit but structurally different incentive to Italy's: a flat 7% tax on foreign-source income for qualifying pensioners, available for up to 15 years — five years longer than Italy's regime — with no small-town residency requirement.
Roth IRA Treatment — Settled
Multiple sources consistently note that Greece may tax Roth IRA distributions as ordinary income despite their US tax-free status, since Greece does not automatically recognize the Roth's unique character. This is consistently described across sources as a real risk rather than a resolved non-issue, similar to Italy and Portugal.
Traditional IRA / 401(k) / Pension Treatment — Settled, with a Qualification Caveat
Under the 7% regime, IRA distributions are explicitly listed among the income types covered by the flat rate. However, as with Italy, whether a specific account clearly qualifies as "employment-related pension income" depends on documentation — one source specifically notes an IRA "may be accepted if it clearly relates to past employment contributions, such as funds rolled over from an employer-sponsored plan like a 401(k)," with qualification depending on how the account is described in supporting certificates.
The 7% Regime, in Brief
- Must not have been a Greek tax resident for 5 of the previous 6 years
- Must transfer tax residence from a country with a double taxation treaty or tax cooperation agreement with Greece (the US qualifies)
- Must demonstrate an employment-related pension — purely passive income (rental, dividends alone) does not qualify for entry, though once qualified, the flat rate extends to other foreign-source income too
- Available for up to 15 consecutive years — the longest duration among the flat-tax retiree regimes reviewed in this guide
- The 7% tax is paid as a lump sum by the end of July each year and cannot be offset by other credits
- Also includes 0% capital gains tax and 5% dividend tax for qualifying participants
Social Security Treatment — Contested
This is a genuine point of difference from Italy: while Italy's treaty assigns Social Security taxation exclusively to the US, sources on Greece's regime specifically list "Social Security benefits" among the income types covered by the 7% flat rate itself — suggesting Greece may tax Social Security (at the reduced 7% rate) rather than treating it as US-exclusive. This is a meaningful structural difference worth confirming directly, since it changes the total tax picture even though 7% is still low.
Wealth Tax Exposure — Not Identified
No wealth tax was identified in this research; Greece does levy ENFIA, an annual property tax based on real estate holdings, which is a property tax rather than a net-worth tax.
Key Planning Consideration
Greece's 15-year window is the longest available among comparable flat-tax regimes in this guide, making it worth serious comparison against Italy's 10-year term for retirees who value duration over the small-town residency requirement Italy imposes — Greece's regime has no equivalent municipality-size restriction.
