EU Tax Residency in 2026:
NHR, Flat Tax and Golden Visa Compared
A residence permit does not determine tax residence, and a preferential tax regime does not eliminate treaty conflicts or U.S. worldwide taxation. The correct country is the one whose residence test, income classification and special regime fit the taxpayer’s actual work, investments, family and citizenship.

Which European regime is actually available in 2026?
Italy is the broadest option for a high-net-worth individual with substantial foreign-source passive income because Article 24-bis TUIR substitutes a fixed annual tax for qualifying foreign income and permits country-by-country exclusions. It is not a flat tax on Italian-source income.
Portugal’s legacy NHR is no longer a general route for new arrivals. It was repealed from 1 January 2024, subject to transitional cases, and replaced by a narrower incentive for scientific research and innovation. Marketing that still presents NHR as open to any new resident is obsolete.
Spain’s inbound-worker regime can be attractive for employment, qualifying remote work and certain entrepreneurial or professional cases, but it is not a general exemption for worldwide investment income.
Greece offers separate regimes for foreign-income taxpayers, pensioners and qualifying employees. Eligibility and economic result depend on the taxpayer category.
Golden Visa is an immigration label
A Golden Visa may permit residence, but it does not itself create a tax exemption. Tax residence must be tested separately under domestic law and any applicable treaty.
What must be decided before comparing tax rates?
| Question | What it controls | Common planning error |
|---|---|---|
| May the person live in the country? | Visa, permit of stay and immigration status. | Assuming the permit determines tax residence. |
| Is the person tax resident? | Worldwide tax base, filing duties and treaty access. | Using only the 183-day count and ignoring home, family, presence or domestic presumptions. |
| Does a special regime apply? | Rate, exemption, substitute tax, duration and eligible income. | Assuming every foreign income category receives the same treatment. |
| What does the other country still tax? | Citizenship taxation, source taxation, exit rules and reporting. | Calculating the European result without the U.S. return or the departure country. |
When does Italy treat an individual as tax resident?
Article 2 TUIR, as amended by Legislative Decree 209/2023, treats an individual as Italian resident when, for most of the tax period and counting fractions of a day, the person has civil-law residence or domicile in Italy, is physically present there, or is presumed resident because of registration in the resident population register. For this purpose, domicile focuses on the place where personal and family relations principally develop.
The conditions are alternatives. A person can therefore become resident without spending more than 183 full days in Italy. Registration, housing, family location, travel records and the practical centre of life must be reviewed together.
How does the Italian Article 24-bis flat tax work?
Article 24-bis is available to qualifying individuals who transfer residence to Italy after being non-resident for at least nine of the previous ten tax years. The election can run for up to 15 years. Qualifying foreign-source income is covered by the annual substitute tax, while Italian-source income remains subject to ordinary Italian rules.
Countries can be excluded from the election. That “cherry-picking” mechanism can preserve ordinary Italian taxation and foreign-tax-credit treatment for selected jurisdictions. The exclusion is often the decisive tool where the fixed tax may not be creditable in another country.
The current fixed amount and effective date must be matched to the taxpayer’s year of transfer; the regime has been increased by successive legislation. The legal effective date is more important than an old article or calculator.
What other Italian regimes may be more appropriate?
- Article 5, Legislative Decree 209/2023: inbound-worker relief for qualifying employment or professional income earned in Italy, subject to residence, qualification and activity conditions.
- Article 24-ter TUIR: 7% substitute tax for qualifying holders of foreign pensions who move to eligible smaller municipalities in specified regions.
- Article 44, Decree-Law 78/2010: relief for qualifying researchers and professors transferring their activity to Italy.
- Ordinary taxation: sometimes better when foreign tax credits, deductions and the income mix produce a lower combined burden.
How do Italy, Portugal, Spain and Greece differ?
| Country or regime | Who it is designed for | Main benefit | Principal limitation in 2026 |
|---|---|---|---|
| Italy · Article 24-bis | New residents with large foreign-source income and the required non-residence history. | Annual substitute tax on qualifying foreign income; country-by-country exclusions; up to 15 years. | Italian-source income remains ordinary; U.S. creditability is not automatic. |
| Italy · inbound workers | Qualifying employees and professionals who move and work mainly in Italy. | Partial exclusion of eligible Italian work income. | Not a regime for passive foreign income; statutory conditions and recapture risk matter. |
| Portugal · legacy NHR | Existing beneficiaries and limited transitional entrants. | Legacy treatment continues for the original period where validly obtained. | Repealed for general new entry from 2024. |
| Portugal · research and innovation incentive | Persons performing listed scientific, innovative or high-value activities through qualifying entities. | Preferential treatment for qualifying activity and certain foreign income. | Narrow eligibility; it is not the old NHR under a new name. |
| Spain · Article 93 regime | Qualifying inbound employees, remote workers, entrepreneurs and specified professionals. | Special non-resident-style taxation during the statutory period. | Income classification and wealth-tax consequences need separate analysis. |
| Greece · foreign-income regime | Qualifying new residents meeting investment and prior-residence conditions. | Fixed annual tax on foreign income for a limited period. | Investment, timing and Greek-source taxation must be modeled. |
Does moving to Europe end U.S. taxation?
No. U.S. citizens and many Green Card holders remain subject to U.S. tax on worldwide income. The European regime must be modeled alongside Form 1040, foreign tax credits, the foreign earned income exclusion where applicable, FBAR, Form 8938 and entity or investment reporting.
A low European tax result can increase residual U.S. tax. A substitute levy may also fail to generate a dollar-for-dollar U.S. foreign tax credit, depending on the nature of the tax, the income category, sourcing, treaty position and current U.S. credit regulations.
PFIC exposure is especially important. European funds, ETFs and insurance wrappers may create Form 8621 obligations and punitive U.S. treatment even when the local regime exempts or favors the investment income.
| U.S. issue | Why the European regime does not solve it | Planning step |
|---|---|---|
| Foreign tax credit | A fixed or substitute tax may not match the same income, source or basket. | Model Form 1116 or corporate credit treatment before electing. |
| FEIE | Applies only to qualifying earned income and does not cover investment income. | Compare exclusion and credit methods annually. |
| PFIC | Local tax exemption does not remove Form 8621 or Section 1291/1296 consequences. | Review every non-U.S. fund before acquisition or migration. |
| Foreign companies | CFC, Subpart F, GILTI and Form 5471 can apply without distributions. | Restructure ownership before residence changes where appropriate. |
| State tax | Some states do not follow federal treaty, credit or residency outcomes. | Establish and document domicile departure separately. |
What happens if two countries claim tax residence?
Domestic residence is tested first in each country. If both countries treat the person as resident and an income-tax treaty applies, the treaty tie-breaker generally examines permanent home, centre of vital interests, habitual abode and nationality in sequence. A treaty position may require disclosure and does not automatically erase domestic filing obligations.
For U.S. citizens, the treaty saving clause commonly preserves U.S. taxing rights except for specified provisions. A tie-breaker conclusion in Europe is therefore not equivalent to ending U.S. worldwide taxation.
When should the move be modeled?
Before the first day that can create residence. The sequencing may affect gains, bonuses, stock compensation, partnership income, trust distributions, company ownership, pension withdrawals and the acquisition or disposal of European investments.
EU tax residency and special regimes: FAQs
Does a Golden Visa make me tax resident?
Not by itself. Immigration status permits residence; tax residence follows domestic statutory tests and, where relevant, treaty tie-breaker rules.
Can a new arrival still claim Portugal’s old NHR regime in 2026?
Generally no. NHR was repealed from 1 January 2024, although existing beneficiaries and limited transitional cases can retain or obtain legacy treatment.
Does Italy’s Article 24-bis tax cover Italian income?
No. The substitute tax applies to qualifying foreign-source income included in the election. Italian-source income remains taxable under ordinary Italian rules.
Is staying fewer than 183 days enough to avoid Italian residence?
No. Article 2 TUIR contains alternative tests, including civil-law residence, domicile centred on personal and family relations, physical presence and an anagraphic presumption.
Does a European preferential regime eliminate U.S. tax for a U.S. citizen?
No. U.S. citizens remain subject to U.S. worldwide taxation. Credits, exclusions and treaty provisions must be applied separately, together with information reporting.
Which regime is best for a U.S. person moving to Europe?
There is no universal answer. Employment income, passive income, company ownership, pensions, investment products, family location and state domicile must be modeled across both systems.
Three households, three different winners
A regime comparison becomes useful only when income composition is fixed. Consider three illustrative households, each with €2 million of annual economic income.
| Household | Income mix | What usually decides |
|---|---|---|
| Founder | €300,000 salary, €1.2 million foreign dividends, €500,000 exit gain | Shareholding CFC rules, timing of the exit, source of work and capital-gain protection. |
| Investor | €1.5 million portfolio income, €500,000 carried interest | Scope of any lump-sum regime, remittance/source rules, wealth taxes and fund classification. |
| Retiree | €180,000 pension, €120,000 IRA withdrawals, €80,000 investment income | Pension treaty, saving clause for U.S. citizens, local pension regime and health/social-security position. |
The founder may prefer a jurisdiction that taxes employment income heavily but protects a properly timed gain; the retiree may reach the opposite conclusion. A “best regime” without an income map is not advice.
Entry tax is only half the model: test years 0, 1 and 6
Year 0 captures pre-arrival dividends, gains, entity reorganisations and basis evidence. Year 1 captures residence commencement, payroll, foreign-asset reporting and the first application. Year 6 or 11 captures expiry, renewal limits, exit taxes and the cost of becoming ordinarily taxable.
Golden visas and residence permits belong in a separate column. Immigration permission does not establish tax residence, and a minimum-presence immigration route can still coexist with residence elsewhere. Likewise, a tax regime does not provide immigration status.
The foreign-tax-credit mismatch that changes the ranking
For a U.S. citizen, a European exemption does not necessarily eliminate U.S. tax because the saving clause and worldwide citizenship taxation remain relevant. Conversely, paying tax in Europe does not guarantee a full Form 1116 credit: source, basket, timing and limitation rules can strand tax.
Model each income item in both currencies and both tax years. A lump-sum regime may charge a fixed amount without allocating tax to specific income, while the United States needs item-level foreign tax to support credits. The nominally cheaper regime can therefore produce the higher combined burden.
State tax must be a third column. Several U.S. states do not follow federal treaty positions and may continue taxing a former resident whose domicile was not clearly abandoned.

Implementation and professional notice
Implementation point. Confirm banking access, health coverage, social-security affiliation and the local adviser’s filing calendar before the move. These non-rate costs can determine whether the selected regime remains operationally sustainable throughout the planned residence period.
