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. Whether foreign tax (such as US tax on IRA withdrawals) can be credited against it is unclear: some sources say the 7% can't be offset by other credits, while others say a credit is available where a treaty gives both countries taxing rights. For US citizens with large IRA withdrawals, this can mean the difference between roughly the US tax alone and paying both taxes in full.
- Per the Greek government, the flat 7% applies to all qualifying foreign-source income, including rents and dividends as well as pensions
Social Security Treatment — Contested
The 1950 US–Greece treaty predates modern Social Security clauses and doesn't address Social Security directly. Its pension article exempts government pensions paid for government service from tax in the other country, and exempts private pensions from tax in the source country; US Social Security fits neither cleanly, which leaves Greece free to tax it as the country of residence. Most practitioners treat it that way, and sources on the 7% regime list Social Security among the income it covers. Some sources claim Greece doesn't tax US Social Security, usually citing the US–Greece Social Security agreement, but that agreement covers contributions and benefits, not income tax.
This is similar to Italy, where US Social Security is also taxable as the country of residence (at 7% in Italy's regime). For a worked example, see Retiring in Greece on $39,400 a Year.
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.
