US Taxes After You Get EU Residency: FATCA, FBAR, FEIE, and What a Golden Visa Does Not Change

US taxes after EU residency work almost exactly the way they worked before, and that is the single most expensive misunderstanding in the American investment migration market right now. 

Interest in leaving is real: in March 2026 the State Department cut the fee to renounce US citizenship from $2,350 to $450, an 80% reduction that took effect on April 13, 2026 (Source: Associated Press). 

But a residence permit is not renunciation, and even renunciation is not a shortcut. 

At Bitizenship, the conversation with American clients starts with a correction: a European residence permit changes where you can live, bank, and travel. 

It does not change who taxes you. This guide explains what actually shifts, what does not, and which forms land on your desk the moment you hold assets abroad.

Key Takeaways

• The US taxes citizens on worldwide income regardless of where they live.
• EU residency adds foreign reporting obligations, it does not remove US ones.
• FEIE requires a foreign tax home, which most Golden Visa holders never establish.
• Italy's flat tax and Portugal's IFICI do not override US tax rules.
• Bitizenship pairs EU residency planning with cross-border tax partners, not IRS avoidance.

Citizenship-Based Taxation: The Rule That Follows the Passport

The United States is one of the only countries on earth that taxes based on citizenship rather than residence. Eritrea is the other commonly cited example. Every other major economy, including Italy and Portugal, taxes people based on where they actually live.

That single design choice drives everything else in this article.

• A US citizen owes US federal income tax on worldwide income, every year, regardless of physical location.
• The obligation survives a move abroad, a foreign residence permit, and even a foreign passport.
• Dual citizenship does not create an election. Holding an Italian or Portuguese passport alongside a US one does not let you choose which country taxes you.
• The obligation ends only through formal renunciation or death, and renunciation has its own tax regime, covered later in this article.
• Filing thresholds abroad are the same as at home, and self-employed Americans face a filing requirement at roughly $400 of net self-employment income.

This is why a second passport for Americans should be understood as an insurance and optionality product, not a tax product. The passport gives you somewhere else to be. The IRS still has your file.

What an EU Residence Permit Actually Changes

Investment migration marketing tends to blur two very different things: mobility and tax residence. They are not the same, and for Americans the gap between them matters enormously.

Here is what an Italian Investor Visa or a Portuguese Golden Visa genuinely gives you.

• The legal right to live in an EU member state, with Schengen travel across 27 countries.
• Access to local healthcare and education systems once you register locally.
• A pathway to permanent residency, and eventually to naturalization, subject to requirements.
• A European banking and business footprint, which is often the real operational unlock.
• Family inclusion for spouses, children, and in some cases dependent parents.

And here is what it does not give you.

• It does not make you a foreign tax resident by itself. Tax residence follows physical presence and domicile rules, not permits.
• It does not reduce your US tax rate on a single dollar.
• It does not exempt you from any US information return.
• It does not, on its own, create foreign taxes you can credit against US tax.

The distinction between residency by investment and tax relocation is where most American applicants get their planning wrong. Getting the permit is the easy part. Deciding whether to actually move, and when, is the part with tax consequences.

FBAR: FinCEN Form 114 and the $10,000 Trigger

The FBAR is the first form most Americans trip over, and it is not even an IRS form. It is filed with FinCEN, separately from your tax return, through the BSA E-Filing System.

The trigger is lower than people expect.

• Any US person with a financial interest in or signature authority over foreign financial accounts must file if the aggregate maximum value exceeded $10,000 at any point during the calendar year.
• It is an aggregate test across all accounts, not a per-account test, and it uses the highest balance during the year, not the year-end balance.
• Signature authority counts even without ownership. A US executive who can sign on a European company account may have a filing obligation.
• The deadline is April 15, with an automatic extension to October 15. No request is required.
• Non-willful penalties are capped per report rather than per account, following the Supreme Court's 2023 decision in Bittner v. United States. Willful penalties are far higher, reaching the greater of $100,000 or 50% of the account balance.

If you open a Portuguese bank account to fund a qualifying investment, or an Italian account to receive distributions, you are in FBAR territory the moment the money lands. That is worth building into your Bitcoin source of funds preparation rather than discovering it the following April.

FATCA: Form 8938 and What Your European Bank Reports

FATCA created two separate obligations, and Americans usually only notice one of them. The one you file is Form 8938. The one your bank files is the reason your European account opening took three weeks and eleven documents.

Form 8938 attaches to your Form 1040 and covers specified foreign financial assets, a broader category than the FBAR's foreign accounts.

• Thresholds depend on filing status and whether you live abroad. A single filer living in the US files at $50,000 on the last day of the year or $75,000 at any point. Married filing jointly doubles those.
• Living abroad raises the bar substantially: $200,000 and $300,000 for single filers, $400,000 and $600,000 for joint filers.
• The asset definition reaches beyond bank accounts to foreign stock held outside a US brokerage, interests in foreign entities, and certain foreign financial instruments.
• The penalty starts at $10,000, with up to $50,000 in additional penalties for continued failure after IRS notice.
• Filing Form 8938 does not excuse the FBAR. Most Americans with European assets file both, reporting overlapping information to two different agencies.

On the institutional side, more than 110 jurisdictions have FATCA agreements with the US, and European banks report US account holders automatically. This is also why some European institutions decline American clients outright, an operational reality that shapes how immigration authorities verify Bitcoin wealth and how smoothly your investment transfer actually clears.

PFICs: The Rule That Punishes European Funds and Crypto Products

The Passive Foreign Investment Company regime is the most punitive corner of the international tax code for ordinary investors, and it catches Americans who think they are simply buying a European fund.

A foreign corporation is a PFIC if either of two tests is met.

• 75% or more of its gross income for the year is passive income, such as interest, dividends, rents, royalties, or certain gains.
• 50% or more of its assets, measured by average value, produce or are held to produce passive income.

Once something is a PFIC, the default consequences are severe.

• Under the default excess distribution regime, gains and large distributions are allocated back across your holding period, taxed at the highest ordinary rate for prior years, and hit with an interest charge on the deferred tax.
• Capital gains treatment disappears. So does the ability to use losses in the ordinary way.
• A Qualified Electing Fund election can improve the outcome, but only if the fund provides an annual PFIC information statement. Many non-US funds simply do not.
• The mark-to-market election is available only for marketable stock, which excludes most private structures.
• Each PFIC generally requires its own Form 8621, which is why a single portfolio of European ETFs can generate a dozen filings.

This matters directly for investment migration. Non-US pooled vehicles, including the private equity structures used for Portugal's Golden Visa fund route, and many non-US crypto products, need a PFIC analysis before subscription rather than after. Ask a cross-border CPA to review the specific structure and confirm what annual reporting the vehicle can supply.

Form 5471: When You Own Shares in a Foreign Company

Direct equity in a foreign corporation is a different animal from a fund interest, and it carries its own filing regime. This is the one that surprises Americans who take a startup equity route into Europe.

Form 5471 obligations turn on categories, not intentions.

• Acquiring 10% or more of a foreign corporation's stock can create a filing obligation in the year of acquisition.
• Control, generally more than 50%, creates broader ongoing obligations.
• If US shareholders collectively control the company, it may be a controlled foreign corporation, pulling in Subpart F and GILTI inclusions that tax you on company earnings you never received in cash.
• The penalty is $10,000 per form per year, with additional penalties for continued failure after notice, and a failure to file can keep the statute of limitations open on your entire return.
• A foreign corporation can be both a CFC and a PFIC candidate depending on its income and asset mix, and the interaction rules are not intuitive.

The practical point for anyone considering Italy's innovative startup route: find out your ownership percentage, the company's income profile, and what reporting package the company provides to US shareholders, before you sign. These are answerable questions. They just need asking early.

FEIE vs the Foreign Tax Credit: Why Golden Visa Holders Often Get Neither

This is the section the CEO of a Golden Visa firm should want written honestly, because the assumption behind most American inquiries is wrong.

The Foreign Earned Income Exclusion under Section 911 lets qualifying Americans exclude a capped amount of foreign earned income.

• For tax year 2026 the maximum exclusion is $132,900 per qualifying person (Source: IRS Revenue Procedure 2025-32), with a separate foreign housing limitation of $39,870 before location adjustments.
• You must have a tax home in a foreign country and meet either the bona fide residence test, which requires residence abroad for an uninterrupted period including a full tax year, or the physical presence test, which requires 330 full days abroad in a 12-month window.
• It applies only to earned income. Dividends, interest, capital gains, rental income, and Bitcoin gains are all excluded from the exclusion.
• Revoking the election generally locks you out for five years without IRS consent.

The Foreign Tax Credit under Section 901 is the other lever, and it works differently. It offsets US tax with foreign income tax actually paid or accrued, subject to sourcing and basket limitations on Form 1116.

Here is the problem for the typical Golden Visa investor. Someone who takes advantage of residency without relocation keeps living in the US, keeps a US tax home, and never spends 330 days abroad. That person fails the FEIE tests entirely. And because they pay little or no European income tax, they have nothing meaningful to credit either. 

The permit is genuine, the mobility is genuine, and the US tax bill is unchanged.

Italy's Flat Tax Regime and the US Tax Bill It Does Not Erase

Italy's substitute tax regime for new residents is the strongest preferential regime left standing in Western Europe, and it is frequently misread by Americans as a way out.

The mechanics are straightforward.

• Qualifying new tax residents pay a flat annual substitute tax on all foreign-sourced income, set at €300,000 as of January 1, 2026, up from €200,000 in August 2024 and €100,000 originally.
• Each additional family member covered pays €50,000 per year.
• Existing beneficiaries are grandfathered at the rate in effect when they entered, for the full 15-year duration.
• Eligibility requires that you were not an Italian tax resident for at least nine of the previous ten fiscal years.
• Italian-sourced income, including dividends from an Italian company, falls outside the regime and is taxed normally.

Now the American overlay. Electing the regime means becoming an Italian tax resident, which means spending real time in Italy. Your worldwide income remains fully taxable in the US.

Whether a lump-sum substitute tax is creditable against US tax, and in which income basket, is a technical question with real disagreement among practitioners. Get it wrong and you can pay €300,000 in Italy and full freight in the US on the same income. 

Anyone weighing Italy's flat tax regime as an American needs that analysis modeled before the move, not after.

Portugal's IFICI Regime and the Same Problem

Portugal replaced the old Non-Habitual Resident regime with IFICI, the Tax Incentive for Scientific Research and Innovation, sometimes called NHR 2.0. It is narrower than what it replaced.

The core terms as of 2026:

• A 20% flat rate on qualifying Portuguese-sourced employment and self-employment income, against progressive rates that reach 48%.
• Exemption on most foreign-sourced income, including dividends, interest, capital gains, rentals, and royalties.
• Pension income is not covered and is taxed at standard progressive rates.
• The regime runs for 10 consecutive years and is non-renewable.
• Eligibility depends on performing a qualifying activity in an approved sector, and on not having been Portuguese tax resident in the previous five years. The Golden Visa does not confer IFICI status.

The American catch is the mirror image of Italy's. IFICI works by exempting foreign income in Portugal. For a US citizen, exempt in Portugal means zero foreign tax credit generated, while the US taxes that same income in full. The regime that helps a British or Brazilian investor most can help an American least. 

That structural asymmetry is one reason Americans getting Portuguese residency should treat the tax regime and the visa as two separate decisions.

Treaties, the Savings Clause, and Social Security

Americans often assume a tax treaty solves the double taxation problem. It helps at the margins, and it is far less powerful than the name suggests.

• The US has income tax treaties with both Italy and Portugal, and both contain a savings clause that preserves the US right to tax its own citizens as if the treaty did not exist, with limited carve-outs.
• Treaties mainly help with sourcing rules, residence tie-breakers, withholding rates, and specific categories like pensions and government service income.
• Totalization agreements are the genuinely useful piece for many movers. The US has social security agreements with both Italy and Portugal, which prevent paying into two social security systems on the same earnings and allow coordination of contribution periods.
• Self-employment tax is not covered by the FEIE. A totalization agreement, correctly documented with a certificate of coverage, is often the only relief available.
• Treaty positions frequently require disclosure on Form 8833, and taking a position without disclosing it carries its own penalty.

For anyone comparing pathways as a US Bitcoin investor, the treaty question belongs in the first conversation with a cross-border CPA, not the last.

State Taxes: The Bill You Might Still Owe After You Leave

Federal is only half the picture, and the state half is where Americans lose money quietly.

• Some states, notably California, New York, New Jersey, and Virginia, apply aggressive domicile rules and continue to treat you as a resident until you affirmatively break ties.
• A foreign residence permit is not evidence of breaking state domicile. Selling the house, changing voter registration, moving your driver's license, and relocating professional and social ties are.
• The FEIE is a federal provision. Most states that tax you do not honor it.
• California in particular applies a safe harbor test with its own conditions, and it does not simply follow federal expatriate rules.
• Establishing a domicile in a zero-income-tax state before departing is a common sequencing step, and it has to happen before the move, not after.

If you're pursuing the fastest European residency route while keeping a home in a high-tax state, model the state exposure alongside the federal one.

Bitcoin and Digital Assets: Where the Reporting Gets Unsettled

Bitcoin-denominated wealth adds a layer that most general immigration advisers are not equipped to handle, and the rules are still moving.

Where things stand as of August 2026:

• Under FinCEN Notice 2020-2, a foreign account holding only virtual currency is not reportable on the FBAR. FinCEN has signaled an intent to change this, and no final rule has been published.
• The exception matters more than the rule: if a foreign exchange account also holds fiat or other reportable assets, the whole account becomes reportable once the $10,000 aggregate threshold is crossed. Stablecoin and fiat balances complicate this.
• Self-custodied wallets sit outside the current proposed FBAR framework, but that is not a permanent answer.
• Form 8938 treatment of digital assets remains an area the IRS has signaled it intends to expand. Treat it as unsettled and document accordingly.
• Broker reporting via Form 1099-DA is now part of the filing cycle, which means the IRS increasingly receives third-party data it can match against your return.
• Every disposal is a taxable event in the US, including converting BTC to EUR to fund a qualifying investment. That conversion is a realization, and it is often the largest single tax item in the entire migration.

The overlap with immigration is direct. The same exchange exports, wallet histories, and chain analysis that support an Italy Investor Visa crypto source-of-funds file are the records your CPA needs for basis and gain calculations. Build one dataset, use it twice.

Exit Tax and Expatriation: The Rare, High-Net-Worth Exception

Renunciation is the only complete exit from US citizenship-based taxation, and it is a narrow, permanent, and expensive decision. It deserves one honest section, not a sales pitch.

You become a covered expatriate if any of three tests is met.

• Average annual net income tax for the five years before expatriation exceeds $211,000 for 2026 expatriations, indexed annually.
• Net worth is $2 million or more on the expatriation date.
• You cannot certify five years of US tax compliance on Form 8854. This third test catches people regardless of wealth.

For covered expatriates, the consequences are structural.

• A mark-to-market deemed sale of worldwide assets on the day before expatriation, with the first $910,000 of net gain excluded for 2026 expatriations (Source: IRS Revenue Procedure 2025-32).
• Special rules for deferred compensation, specified tax-deferred accounts, and non-grantor trust interests.
• Under Section 2801, future gifts or bequests to US persons can trigger a transfer tax on the US recipient, which reaches your heirs long after the fact.
• Immigration consequences: a former citizen generally needs a visa or Visa Waiver eligibility to enter the US.
• The State Department fee is now $450 as of April 13, 2026, down from $2,350, and the Department estimates roughly 4,661 people apply for a Certificate of Loss of Nationality each year (Source: US Department of State).

The sequencing point is the one people miss. You cannot responsibly renounce without another citizenship in hand, and Italian naturalization requires ten years of genuine legal residence at 183 or more days per year, while Portugal's revised Nationality Law sets a ten-year clock for non-EU and non-CPLP nationals running from the issuance of the first residence card. 

Renunciation is a decade-out conversation, not a Golden Visa feature. The realistic citizenship timelines across Europe should anchor that discussion.

How to Sequence the Visa and the Tax Plan

Where the team at Bitizenship lands is simple: the residency decision and the tax decision are two different projects, and they should run in parallel with different specialists.

A workable sequence looks like this.

• Define the objective first. Mobility and family security, tax optimization, and eventual citizenship pull in different directions and imply different physical presence strategies.
• Audit your source-of-funds documentation and your cost basis records at the same time, because they draw on the same underlying data.
• Get a PFIC and Form 5471 read on the specific investment vehicle before you subscribe, not after the wire clears.
• Model the state tax exit if you live in a high-tax state, and handle it before departure.
• Run the treaty and totalization analysis with a cross-border CPA if you intend to actually relocate, and model the Italian substitute tax or Portuguese IFICI interaction with the US credit rules explicitly.
• Only then choose the program.

"Bitcoin holders aren't a new type of investor. They're a new type of citizen. They think in decades, in optionality, in sovereignty. We built Bitizenship for that person." - Alessandro Palombo, Co-Founder of Bitizenship.

That decade-long frame is exactly the right one here, because the tax questions in this article compound over years, not quarters.

Alessandro Palombo writes weekly on how these pieces fit together for globally mobile Bitcoin holders in The Ale's Letter, which is a useful place to follow the regulatory changes between the time you start researching and the time you file.

Bitizenship supports the residency side through the Italy program and the Portugal program, with administrative assistance and vetted legal and tax partner introductions. It is not a US tax adviser, and it should not be treated as one. The right pairing is a residency partner and an independent cross-border CPA, engaged in the same conversation.

Conclusion

US taxes after EU residency remain a US problem, and no Golden Visa, Investor Visa, or second passport changes that. Citizenship-based taxation follows the passport. 

FBAR, Form 8938, PFIC reporting, and Form 5471 arrive as additions to your obligations, not substitutes for them. The FEIE requires a foreign tax home most investors never establish, and the foreign tax credit needs foreign tax you may never pay. Italy's flat tax and Portugal's IFICI are real advantages for the right profile, and neither one overrides the Internal Revenue Code. 

What a European residence permit actually buys is optionality, family security, Schengen access, and a legal right to be somewhere else, which is worth a great deal on its own terms. Plan the visa and the tax structure together, with a qualified cross-border CPA on the call, and you avoid the expensive surprises.

FAQs:

1. Do US taxes after EU residency change if I get a Golden Visa?

No. US citizens are taxed on worldwide income regardless of where they hold residency, so US taxes after EU residency work the same way they did before. A Portuguese Golden Visa or an Italian Investor Visa grants the right to live, work, and travel in the EU. It does not alter your US filing obligations, your tax rate, or your reporting requirements. Bitizenship consistently frames its programs as mobility and optionality products rather than tax products, and recommends that American clients engage an independent cross-border CPA alongside the residency process.

2. Which forms apply to US taxes after EU residency for Americans with foreign accounts?

The main ones are FinCEN Form 114, known as the FBAR, and IRS Form 8938 under FATCA. The FBAR applies when foreign financial accounts exceed $10,000 in aggregate at any point in the year, and Form 8938 applies at higher thresholds that vary by filing status and whether you live abroad. Depending on your holdings, Form 8621 for PFICs and Form 5471 for foreign corporations may also apply. Bitizenship's role covers the immigration and investment structuring side, and clients are directed to qualified tax professionals for the filings themselves.

3. Does the Foreign Earned Income Exclusion help with US taxes after EU residency?

Often it does not. The FEIE, capped at $132,900 for tax year 2026, requires a foreign tax home plus either bona fide residence abroad for a full tax year or 330 full days abroad in a 12-month period. Investors who use Portugal's 14-days-every-two-years stay requirement, or Italy's Investor Visa with no minimum stay to maintain the permit, generally fail both tests. It also covers only earned income, not investment or Bitcoin gains. Bitizenship encourages American clients to test this assumption with a CPA before assuming any US tax benefit.

4. Do Italy's flat tax and Portugal's IFICI reduce US taxes after EU residency?

No. Both are domestic European regimes that reduce or exempt local tax, and neither overrides US citizenship-based taxation. Italy's substitute tax regime sits at €300,000 annually on foreign-sourced income as of January 1, 2026, plus €50,000 per additional family member, while Portugal's IFICI applies a 20% flat rate to qualifying Portuguese income and exempts most foreign income, with pensions excluded. Because exempt foreign income generates no creditable foreign tax, these regimes can create unfavorable interactions for Americans. Bitizenship works with vetted tax partners who model this before a client commits to a move.

5. Is renouncing citizenship the only way to end US taxes after EU residency?

Formal renunciation is the only complete exit, and it is a permanent decision with its own tax regime. Covered expatriate status attaches if average annual net income tax exceeds $211,000 for 2026 expatriations, net worth reaches $2 million, or five years of tax compliance cannot be certified on Form 8854, triggering a mark-to-market deemed sale with a $910,000 gain exclusion for 2026. It also requires holding another citizenship first, which for Italy means ten years of genuine residence and for Portugal a ten-year clock under the revised Nationality Law. Bitizenship treats this as a rare, long-horizon topic for a small subset of clients, not as the purpose of its programs.
