US Persons Moving to Cyprus (2026): FATCA, GILTI, Subpart F, FEIE and the CFC Trap

A US citizen who moves to Cyprus has two tax residences for life: the one they earn by living in Cyprus, and the one the United States keeps on their passport. This article unpacks the US side in detail — every form, every regime, and the single biggest trap (a Cyprus company directly owned by a US person) — then shows where Cyprus non-dom still adds value.

Citizenship-based taxation: the core problem

The United States taxes its citizens and lawful permanent residents (green-card holders) on worldwide income regardless of where they live. Only two countries apply full citizenship-based taxation — the US and Eritrea. For a US person in Cyprus this means:

• An annual Form 1040 reporting worldwide income, including Cyprus dividends, interest, Cyprus rental income, and capital gains.
• The full international reporting suite (FBAR, Form 8938, Form 5471 for CFCs, Form 8621 for PFICs, Form 3520 for foreign trusts and large foreign gifts).
• State tax questions if you moved from a sticky state (California, New York, Virginia, New Mexico, South Carolina) — severing state residence requires evidence.
• No US tax exemption for simply being a Cyprus tax resident.

Filing obligations that follow you to Cyprus

FBAR and FATCA (Form 8938)

Two separate foreign-account reporting regimes, with different thresholds, filed with different agencies:

• FBAR (FinCEN Form 114). Required if the aggregate highest balance across all foreign financial accounts exceeds USD 10,000 at any point during the calendar year. The threshold is aggregate, not per-account. Due 15 April with an automatic extension to 15 October. Filed electronically through the BSA E-Filing System.
• Form 8938 (FATCA). Filed with your 1040. Thresholds depend on filing status and residence. For a US person living abroad (unmarried or married filing separately): USD 200,000 on the last day of the year or USD 300,000 at any time during the year. Married filing jointly, living abroad: USD 400,000 / USD 600,000.

FBAR penalties for non-wilful violations run to ~USD 10,000 per violation (indexed), and to the greater of ~USD 100,000 or 50% of the account balance for wilful violations. Form 8938 carries its own USD 10,000 penalty stack.

The Foreign Earned Income Exclusion

The FEIE (Form 2555) lets a qualifying US person exclude a capped amount of foreign earnedincome (salary, wages, self-employment, directors' fees) from US tax. Passive income — dividends, interest, capital gains, rent — is not eligible.

A married couple where both spouses qualify can each claim the FEIE on their own earnings, doubling the exclusion. To qualify, the taxpayer meets one of two tests:

• Physical Presence Test: physically present in a foreign country or countries for at least 330 full days in any 12-month period.
• Bona Fide Residence Test: a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year.

FTC vs FEIE: the real-world trade-off

The two main tools to avoid double tax — the Foreign Earned Income Exclusion (Form 2555) and the Foreign Tax Credit (Form 1116) — produce different outcomes depending on your situation:

• FEIEremoves income from the US base entirely. But it also uses up your low US tax brackets — taxable income above the FEIE is taxed as if the excluded amount sat at the bottom of your bracket ("stacking rule"). And FEIE does not cover passive income.
• FTC gives a dollar-for-dollar US tax credit for foreign income tax paid, up to the US tax on the same income. Unused FTC carries back one year and forward ten.

Cyprus-specific analysis:for a US person earning employment or director's-fee income from a Cyprus company, Cyprus tax on that income can be low because of the €22,000 tax-free threshold and the 20% starter bracket. Cyprus tax paid may be less than US tax on the same income — so the FEIE typically beats the FTC for modest salaries.

For higher earners pushed into Cyprus' 30%/35% brackets, or for dividend income where Cyprus tax is 0% (non-dom), the FTC usually beats FEIE — or neither fully solves the double-tax problem and careful mixing is needed. This is a per-taxpayer, per-year model.

The CFC trap: Cyprus company + US owner

This is the defining planning issue. A foreign corporation is a Controlled Foreign Corporation under US rules if US shareholders (each owning 10% or more of vote or value) together own more than 50% of the stock. A single US founder of a Cyprus Ltd owns 100% — so it is automatically a CFC.

A CFC status triggers:

• Annual Form 5471 filing (all categories depending on specific facts).
• Subpart F current-year inclusion of certain categories of CFC income.
• GILTI (from 2026 renamed NCTI — Net CFC Tested Income) current-year inclusion on most active income that is not Subpart F.
• No deferral: the US owner is taxed today on CFC earnings, even if the CFC retains the cash.

The net effect: the Cyprus 15% corporate tax and the 0% non-dom dividend rate stop being the full story. The US owner pays additional US tax at the GILTI/NCTI effective rate in the year the income is earned, with a foreign tax credit for the Cyprus corporate tax paid.

GILTI (and the 2026 rebrand to NCTI)

GILTI is the regime that taxes a US shareholder on the active, non-Subpart-F income of their CFC each year, after a deemed return on tangible assets. The One Big Beautiful Bill Act (OBBBA, enacted 2025) rebranded GILTI to Net CFC Tested Income (NCTI) and retuned the numbers starting with tax years beginning after 31 December 2025.

The net top effective US rate on NCTI for 2026 is commonly modelled at ~14% (post-haircut, assuming sufficient foreign tax credits). For a Cyprus CFC paying 15% Cyprus corporate tax, the US NCTI top-up after the 90% foreign-tax-credit and the 40% §250 deduction can often be zero or near-zero, because 15% Cyprus × 90% ≈ 13.5% > 12.6% effective rate — but this is a sensitive calculation and can break with timing differences, high-taxed exclusion elections, or mixed income categories.

Subpart F income

Subpart F is the older regime that taxes the US shareholder currently on certain passive or related-party categories of CFC income:

• Foreign personal holding company income (dividends, interest, royalties, rents, net gains from commodities and property).
• Foreign base company sales income.
• Foreign base company services income.

A Cyprus holding company earning intra-group interest or royalties from a related US subsidiary is the textbook Subpart F fact pattern. Subpart F applies before NCTI — income caught by Subpart F is not also in NCTI. The high-taxed exception (§954(b)(4)) can exclude Subpart F income that has been taxed at more than 90% of the top US corporate rate (~18.9% at current 21% US corporate).

PFIC: avoid Cyprus mutual funds and EU ETFs

A Passive Foreign Investment Company is any non-US corporation where either ≥ 75% of income is passive (income test) or ≥ 50% of assets produce passive income (asset test). The consequences for a US holder:

• Under the default (§1291) regime: "excess distributions" and dispositions are taxed at the highest marginal US rate, plus an interest charge for the deferred periods.
• A QEF (§1295) election avoids the penalty regime but requires the fund to produce annual PFIC statements — most EU UCITS do not.
• A mark-to-market election is available for marketable PFICs but produces ordinary-income treatment on annual gains.

Nearly every EU-domiciled ETF (UCITS) and Cyprus unit trust is a PFIC. A US person with a Cyprus brokerage account who buys iShares Core MSCI World UCITS ETF creates a PFIC problem. The practical rule is: hold US-domiciled ETFs in a US brokerage, or use individual securities. Do not hold EU UCITS as a US person.

The US-Cyprus tax treaty

The Convention between the US and Cyprus for the Avoidance of Double Taxation was signed at Nicosia on 19 March 1984. Instruments of ratification were exchanged at Washington on 31 December 1985. The treaty entered into force on that date, with general effect from 1 January 1986. Key provisions:

• US withholding on dividends to a Cyprus resident reduced to 5% (direct-investment dividends, ≥ 10% voting stock) or 15% (portfolio).
• US withholding on interest to a Cyprus resident generally 10%.
• Royalties generally 0%.
• Saving clause preserves the US right to tax its own citizens and residents — the treaty does not reduce US tax on a US citizen living in Cyprus, except for specified relief items.
• Mutual agreement procedure for competent authority dispute resolution.

The treaty is functional for structuring investment flows in and out of Cyprus but does not solve the citizenship-based-taxation problem.

Cyprus non-dom: what it still buys a US person

Cyprus non-dom status is meaningful at the Cyprus layer but not a magic bullet for a US person:

• What it saves: Cyprus Special Defence Contribution on dividends (5% from 2026), interest (17%) and rental income (3%) — all down to 0% for 17 years. If you are a Cyprus-dom individual, non-dom is a material Cyprus-side saving.
• What it does not save: your US tax on the same income. US dividends, US interest, US capital gains, and worldwide portfolio income remain subject to US tax at US rates (with FTC for any Cyprus tax paid).
• Net effect for a US person: non-dom turns Cyprus into a low-friction personal tax jurisdiction that layers under your US return. It is still worth having — read the full non-dom explainer.

The §877A exit tax (for those giving up US status)

Some US founders eventually conclude that the compliance and tax burden of US citizenship is not worth paying forever. Section 877A imposes a mark-to-market exit tax on covered expatriates.

You are a covered expatriate for 2026 if you meet any of:

• Net worth test: worldwide net worth of USD 2 million or more on the day before expatriation.
• Income tax test: average annual net US income tax liability over the 5 years before expatriation greater than approximately USD 211,000 (inflation-indexed).
• Certification test: failure to certify (on Form 8854) compliance with US federal tax obligations for the preceding 5 years.

For covered expatriates, §877A deems a sale of all worldwide assets on the day before expatriation. Gain above the exclusion amount — USD 910,000 for 2026 — is subject to US tax at the applicable rates. Expatriation is accomplished by renouncing citizenship at a US consulate (citizens) or filing Form I-407 (long-term green-card holders). Form 8854 must be filed with the final US tax return.

Planning: the clean structures

The architectures that work for US founders moving to Cyprus:

1. Keep the US LLC; run from Cyprus.A US LLC (single- member, disregarded) owned by a Cyprus-resident US citizen avoids creating a CFC. The LLC's income flows through to the individual, subject to US self-employment tax where applicable. Cyprus will assess whether the LLC is Cyprus tax resident by virtue of management and control — often yes — so the Cyprus view may still tax the profits, with US tax credited.
2. Cyprus company with a Check-the-Box election. A Cyprus Ltd can elect under US rules to be treated as a disregarded entity or partnership. This eliminates CFC, GILTI and Subpart F at the US level; the Cyprus Ltd remains a Cyprus tax-resident company paying 15%. This is the most common clean answer for a single US founder.
3. Cyprus operating + US S-corp above (only for US-only customers).Rarely a good fit for international revenue.
4. Accept the CFC and optimise. Full Form 5471 compliance, high-taxed exclusion elections where available, and careful FTC management can produce an acceptable outcome, but the compliance cost is material (~USD 7,500–25,000 per year, versus USD 2,000–4,000 for the cleaner options).
