U.S. Taxes for Americans Living in Italy: The 2026 Guide

Key takeaways

• Moving to Italy does not end U.S. tax filing. The U.S.–Italy treaty contains a "saving clause" (Article 1(2)) that lets the United States tax its citizens as if the treaty did not exist, subject to listed exceptions. You keep filing Form 1040 every year you meet the filing threshold.
• Italy is a high-tax country, so the Foreign Tax Credit (FTC) usually beats the Foreign Earned Income Exclusion (FEIE) for employees on ordinary Italian rates. The calculus can flip if you use Italy's impatriati regime, which roughly halves your Italian taxable work income.
• Self-employed U.S. citizens in Italy are generally covered by U.S. Social Security, not Italy's INPS, under the U.S.–Italy totalization agreement — so you pay U.S. self-employment tax, which neither the FEIE nor the FTC reduces. Dual U.S./Italian nationals working in Italy may elect either system.
• If you are a dual U.S.–Italian national resident in Italy, your U.S. Social Security benefits are taxable only by Italy. The Protocol carves this out of the saving clause; a U.S.-only citizen does not get the same result.
• Italian investment funds and ETFs are a PFIC trap. Non-U.S. mutual funds and ETFs can trigger Form 8621 and punitive default taxation. U.S. IRAs are protected from PFIC shareholder treatment; Italian accounts generally are not.
• Italy taxes and monitors your U.S. accounts too. As an Italian resident you report foreign (including U.S.) financial assets on quadro RW and generally pay IVAFE on them, while the U.S. side requires FBAR and possibly Form 8938 for your Italian accounts.

Who this applies to, and why living in Italy changes nothing on the U.S. side

The United States taxes on the basis of citizenship. IRS Publication 54 states that if you are a U.S. citizen or resident alien, your worldwide income is generally subject to U.S. income tax regardless of where you live, and the same filing requirements apply as for someone living in the United States.

The saving clause. The current U.S.–Italy income tax convention was signed on August 25, 1999. Article 1(2) provides that, notwithstanding any other provision except Article 1(3), each country may tax its residents (as determined under Article 4) and its citizens by reason of citizenship as if there were no convention. The Treasury Technical Explanation describes this as "the traditional saving clause found in U.S. tax treaties."

The exceptions in Article 1(3)(a), which apply to everyone, including U.S. citizens, are:

• Article 9(2) (correlative transfer-pricing adjustments);
• Article 18(5) and 18(6) (alimony/child support, and pension-fund contributions);
• Article 23 (relief from double taxation);
• Article 24 (non-discrimination); and
• Article 25 (mutual agreement procedure).

Article 1(3)(b) lists benefits (Articles 19, 20, 21 and 27) that are preserved only for individuals who are neither citizens of nor immigrants to the taxing country — so they do not help U.S. citizens in the U.S. Protocol Article 1(2) adds two further carve-outs: the Article 18(2) social security rule for residents who are nationals of the residence country (even if also nationals of the other), and the Protocol Article 4 rule for U.S. citizens in Italy who are partners in a U.S. partnership.

Former citizens. Protocol Article 1(1) extends the U.S. definition of "citizen" for saving-clause purposes to a former citizen or long-term resident whose loss of status had tax avoidance as one of its principal purposes, for 10 years after the loss.

Residence under the treaty. Article 4(2) contains the standard tie-breaker for individuals resident in both countries under domestic law: (a) permanent home; if in both, center of vital interests; (b) habitual abode; (c) nationality; (d) competent-authority agreement. For a U.S. citizen, winning the tie-breaker in favor of Italy does not remove U.S. citizenship-based taxation — the saving clause still applies. Protocol Article 1(5)(c) adds that Italy will treat a U.S. citizen or green-card holder as a U.S. resident for treaty purposes only if that person has a substantial presence, permanent home or habitual abode in the United States. The Technical Explanation confirms that a citizen who fails this test is still taxed on worldwide income under the Code.

Green-card holders. Unlike citizens, a green-card holder who is treated as an Italian resident under the tie-breaker is, per the Technical Explanation, subject to U.S. tax only to the extent permitted by the treaty. Claiming that position has other consequences (including for long-term-resident expatriation rules) and should be planned with an adviser.

Italian residence (domestic law). From 2024, Italy's Article 2 TUIR (as amended by Legislative Decree 209/2023) treats an individual as resident if, for most of the tax year (183 days, or 184 in a leap year), any one of several criteria is met, including registration in the population register, residence, domicile, or physical presence in Italy; Agenzia delle Entrate Circular 20/E of November 4, 2024 indicates that fractions of a day count toward physical presence. (Summaries of Circular 20/E published by Italian professional outlets (IPSOA, ecnews.it, fiscoetasse.com); the Circular itself was not retrieved from agenziaentrate.gov.it during this review.)

What the U.S.–Italy treaty actually says

Which treaty applies

Two treaties appear on the IRS Italy treaty page: a 1984 convention and the 1999 convention. The 1999 convention replaced the 1984 one. A Treasury press release (TG-454) announced its entry into force on the day ratification instruments were exchanged in Rome, with effect for withholding taxes on amounts paid on or after February 1, 2010, and for other taxes for taxable years beginning January 1, 2010. The entry-into-force date of December 16, 2009 is reported by secondary sources. (Orbitax treaty news item; the TG-454 press release as retrieved did not display its date.)

Taxes covered

• United States (Art. 2(2)(a)): federal income taxes under the Internal Revenue Code (excluding social security taxes), plus the federal excise taxes on insurance premiums paid to foreign insurers and on private foundations. U.S. state and local taxes are not covered, except for the non-discrimination article (Technical Explanation, Article 2).
• Italy (Art. 2(2)(b)): IRPEF (individual income tax), IRES (corporate income tax), and IRAP (regional tax on productive activities) — but only the portion of IRAP treated as an income tax under the formula in Article 23(2)(c).

Italy's wealth-type levies on foreign assets (IVAFE, IVIE) are not listed in Article 2. Whether they are creditable for U.S. purposes under general Code rules was not found in the sources reviewed. (No IRS ruling or guidance on the creditability of IVAFE/IVIE was located.)

Main income categories (as they apply to residents of Italy)

Item	Treaty rule	Article
Dividends	Source country may tax at up to 15% (5% for companies owning ≥25% voting stock for 12 months)	10(2)
Interest	Source country may tax at up to 10%; certain exemptions	11(2)–(3)
Royalties	Up to 5% (software, equipment), 8% otherwise; literary/artistic/scientific copyright royalties taxable only in residence state	12
Capital gains on movable property	Generally only in residence state; real property may be taxed where located	13
Independent personal services	Taxable only in residence state unless a fixed base in the other state	14
Employment income	Taxable where the work is exercised, with a 183-day / foreign-employer exception	15
Private pensions for past employment	Taxable only in residence state	18(1)
Social security payments	Taxable only in the residence state of the recipient	18(2)
Lump-sum/severance paid after a change of residence	Taxable only in the state where the employment was exercised	18(3)
Annuities	Taxable only in residence state	18(4)
Alimony and child support	Taxable only in the payer's residence state; not taxable in either if the payer gets no deduction	18(5)
Other income	Taxable only in residence state	22

Remember: for a U.S. citizen, every "taxable only in Italy" rule above is overridden by the saving clause unless the article is listed as an exception. What the citizen gets instead is the special credit mechanism in Article 23(4).

How double taxation is actually relieved for U.S. citizens in Italy — Article 23(4)

This is the operative provision for most readers. Where a U.S. citizen is resident in Italy:

1. Italy credits first, but only up to what the U.S. could charge a non-citizen. For income that the treaty exempts from U.S. tax (or subjects to a reduced rate) when received by an Italian resident who is not a U.S. citizen, Italy allows a credit against Italian tax no larger than the U.S. tax that would be due if the person were not a citizen (Art. 23(4)(a)).
2. The U.S. then credits the Italian tax remaining after Italy's credit (Art. 23(4)(b)).
3. Re-sourcing. Solely for the U.S. credit computation, that income is deemed to arise in Italy to the extent necessary to avoid double taxation (Art. 23(4)(c)) — which matters because the FTC limitation normally only allows credits against U.S. tax on foreign-source income.

Practical effect: on a U.S. pension or U.S. Social Security (exempt from U.S. tax for a non-citizen Italian resident), Italy's credit is zero, Italy taxes in full, and the U.S. credits Italy's tax against its own on that income. On U.S.-source portfolio dividends, the U.S. keeps up to the 15% treaty rate, Italy credits that 15%, and the U.S. credits the residual Italian tax.

A caveat on Italy's side. Article 23(3) states that Italy grants no credit for U.S. tax if the item is subjected in Italy to a final withholding tax at the recipient's request under Italian law. Many Italian residents' investment income is taxed through substitute taxes or final withholding by Italian intermediaries. How Italy applies this sentence to a U.S. citizen's U.S.-source dividends held through an Italian intermediary was not confirmed in the sources reviewed. (Italian administrative practice on Art. 23(3) final-withholding exclusion was not located in Agenzia delle Entrate sources.)

Features worth noting in this treaty

• Social security of dual nationals. Protocol Art. 1(2)(a) means the saving clause does not override Article 18(2) for residents of Italy who are Italian nationals, even if also U.S. nationals. The Technical Explanation states expressly that when the United States pays social security to an Italian resident who is a citizen of both countries, only Italy can tax that payment.
• Pension contributions (Art. 18(6)). Contributions to a plan established in one country by an individual working in the other may be deductible or excludible in the work country — but only if contributions were made before arriving in that country and the competent authority of the work country has agreed the plan generally corresponds to a domestically recognized plan. Protocol para. 15 specifies that, for Italy, "pension plan" means fondi pensione. Whether the Italian competent authority has issued any determination that U.S. 401(k) plans or IRAs correspond to Italian recognized plans was not found in the sources reviewed.
• Severance (TFR) after moving (Art. 18(3)). Lump-sum or severance payments received after a change of residence, for work done in the first country while resident there, are taxable only in that first country. Article 18(3) is not a saving-clause exception, so a U.S. citizen who leaves Italy still reports Italian TFR on the U.S. return and relies on the FTC.
• IRAP partially covered. Only a formula-based portion of IRAP is treated as an income tax for treaty and U.S. credit purposes (Art. 23(2)(b)–(c)).
• Mutual agreement deadline. A case must be presented within three years of the first notification of the action resulting in taxation not in accordance with the treaty (Art. 25(1)).
• Limitation on benefits. Individuals qualify automatically (Protocol Art. 2(2)(a)).

(A note on sourcing: the Technical Explanation retrieval for this guide covered its commentary through Article 10. Commentary on Articles 18 and 23 was not retrieved, so statements on those articles rest on the treaty text itself.)

FEIE vs. Foreign Tax Credit in Italy

For the general mechanics of each tool, the stacking rule, and worked 2026 examples outside Italy's specific rates, see our guide on FEIE vs. Foreign Tax Credit.

The two tools

• FEIE (Form 2555). For 2026 the exclusion is $132,900 per qualifying individual (IRS IR-2025-103; Rev. Proc. 2025-32). To qualify you need a foreign tax home and must meet the bona fide residence test or the 330-day physical presence test (Pub. 54, ch. 4). Tax on your remaining income is computed at the rates that would apply without the exclusion (Pub. 54, "Figuring tax on income not excluded").
• FTC (Form 1116). Credits Italian income tax against U.S. income tax on foreign-source income, subject to the limitation. You cannot take a credit or deduction for foreign taxes on income you exclude (Pub. 54, ch. 5). Unused credits can be carried forward 10 years (IRC §904(c), as described in IRS Chief Counsel memorandum 201111009) and carried back one year. (The one-year carryback is stated in Pub. 54's "Foreign tax credit carryback and carryover" section, whose text was not retrieved; the 10-year carryforward is confirmed by the IRS memorandum.)

Neither tool reduces U.S. self-employment tax: Pub. 54 states self-employment income must be counted for SE tax even if excluded under the FEIE.

Which usually wins in Italy

Italy's IRPEF for 2026 uses three brackets: 23% up to €28,000; 33% from €28,000 to €50,000; 43% above €50,000, with the middle rate cut from 35% by the 2026 Budget Law. Regional and municipal surcharges (addizionali) are added on top and vary by location. (Andersen Italy client note on the 2026 Budget Law (Jan. 2026) and several Italian tax publications; the text of Law 199/2025 and the corresponding Agenzia delle Entrate page were not retrieved.)

Because Italian tax on employment income at ordinary rates typically exceeds U.S. tax on the same income, the FTC often eliminates U.S. income tax and builds carryforwards; the FEIE also eliminates U.S. tax on income under the cap but builds nothing. The exception is when Italian tax is unusually low — most commonly under the impatriati regime (see below).

2026 worked comparison — employee in Milan

Assumptions (illustrative, not quoted rates): single filer; gross salary €92,000; Italian taxable income €85,000 after employee social contributions (assumed €7,000); no Italian detrazioni; combined regional + municipal surcharge assumed at 2.5%; exchange rate assumed at $1.15 / €1 (for a real return, use the rate method described in Pub. 54 "Foreign Currency"). Standard deduction $16,100 and 2026 brackets per IRS IR-2025-103.

Italian tax (ordinary rates):

• IRPEF: €28,000 × 23% = €6,440; €22,000 × 33% = €7,260; €35,000 × 43% = €15,050 → €28,750
• Surcharges (assumed 2.5% × €85,000) → €2,125
• Total ≈ €30,875 ≈ $35,506

U.S. side:

• Wages: €92,000 × 1.15 = $105,800. Italian employee social contributions are not deducted for U.S. income tax. (The non-deductibility/non-creditability of Italian social contributions paid under a totalization agreement is not confirmed in the sources retrieved for this guide.)
• Taxable income: $105,800 − $16,100 = $89,700
• Tax: 10% × $12,400 = $1,240; 12% × $38,000 = $4,560; 22% × $39,300 = $8,646 → $14,446

	Option A — FTC	Option B — FEIE
U.S. income tax before relief	$14,446	$0 (all $105,800 excluded; under $132,900 cap)
Credit used	$14,446 (limited to U.S. tax on foreign-source income)	n/a
U.S. income tax due	$0	$0
Excess Italian tax carried forward	≈ $21,060 (general category)	none

Both options produce zero U.S. income tax here, but the FTC route preserves about $21,000 of carryforwards, which can absorb U.S. tax in a later year when Italian tax is lower (e.g., a bonus year with low Italian withholding timing, or general-category income from a short U.S. assignment). Carryforwards in the general category cannot be used against passive-category income such as investment income. (Category-matching rule stated from general FTC principles; Pub. 514 not retrieved.)

Same employee under the impatriati regime. Italy's regime for workers moving to Italy (Art. 5, Legislative Decree 209/2023) taxes qualifying employment and self-employment income at 50% of its amount (60% exempt with a minor child, per some sources), up to €600,000 per year, subject to conditions including prior non-residence and a minimum stay. (Il Sole 24 Ore (NT+ Diritto), diritto.it, fiscoinvestimenti.it; the legislative text and Agenzia circular were not retrieved.)

• Italian taxable income: 50% × €85,000 = €42,500 → IRPEF €6,440 + €4,785 = €11,225; surcharges ≈ €1,063 → total ≈ €12,288 ≈ $14,131
• FTC route: $14,446 − $14,131 = ≈ $315 U.S. tax due, no carryforward
• FEIE route: $0 U.S. tax due

When Italian tax drops below U.S. tax, the FEIE (or a combination of FEIE and FTC on income above the cap) can come out ahead. Once you revoke the FEIE you generally cannot re-elect it for several years without IRS consent; Pub. 54 discusses this under "Effect of Revoking the Exclusions." (The five-year waiting period is described in Pub. 54 ch. 4, whose text for that subsection was not retrieved.)

Social Security: the U.S.–Italy totalization agreement

Italy and the United States have a totalization agreement, effective November 1, 1978, with a supplementary agreement effective January 1, 1986 that did not change the coverage and tax provisions (SSA POMS RS 02001.050). The agreement eliminates dual coverage for the same work, and can combine credits to qualify for benefits (SSA POMS GN 01705.001).

Employees. The IRS describes the general pattern of totalization agreements: you are generally subject to social security only in the country where you work, but a worker temporarily sent abroad can generally remain covered only by the U.S. system (Pub. 54, ch. 2). For exemption from U.S. coverage when working for an employer in Italy, SSA explains that the Italian employer requests a certificate of coverage (form IT/USA 4) from the provincial INPS office. The maximum duration of a "detached worker" assignment under the Italy agreement was not found in the sources reviewed.

Self-employed — the counter-intuitive rule. Per SSA's agreement description:

• A self-employed U.S. national who would otherwise be covered by both countries is covered only by U.S. Social Security — meaning U.S. self-employment tax is due, and INPS contributions should not be.
• Self-employed dual U.S./Italian nationals working in Italy may elect U.S. or Italian coverage.
• Italian nationals self-employed in Italy may also elect.

To prove U.S. coverage to Italy, request a certificate of coverage from SSA's Office of Earnings and International Operations (Pub. 54, ch. 3). If you elect Italian coverage as a dual national, SSA says to attach the certificate to your U.S. return every year as proof of exemption from U.S. SE tax.

Benefits. The U.S. can count Italian credits only if you have at least six U.S. credits and do not already qualify on U.S. credits alone (SSA).

Taxation of benefits. See What the U.S.–Italy treaty actually says above: Article 18(2) plus Protocol Art. 1(2)(a) make U.S. Social Security taxable only in Italy for a U.S.–Italian dual national resident in Italy; a U.S.-only citizen remains within the saving clause and relies on Article 23(4).

U.S. retirement accounts (401(k), IRA, Roth)

What the treaty says. Article 18(1) gives exclusive taxing rights to the residence country over "pensions and other similar remuneration" paid for past employment; Article 18(4) does the same for annuities. Neither article mentions 401(k) plans, IRAs or Roth IRAs by name. Whether an IRA distribution falls under Article 18(1), 18(4) or 22 ("other income") is not resolved in the treaty text; all three point to the residence state. (No Technical Explanation commentary on Article 18 was retrieved; classification of IRA distributions under this treaty was not found in primary sources.)

What that means for a U.S. citizen. Article 18 is not a saving-clause exception (except paragraphs 5 and 6), so the U.S. continues to tax 401(k)/IRA distributions under the Code. Italy, as residence state, may also tax them; double taxation is relieved through Article 23(4).

What is protected:

• Contributions while working in Italy (Art. 18(6)) — only if contributions began before you moved and the Italian competent authority has agreed the plan corresponds to an Italian recognized plan. No such determination was found in the sources reviewed.
• PFIC protection inside IRAs. The Form 8621 instructions state that a U.S. person owning PFIC stock through an individual retirement plan or annuity (IRC §7701(a)(37)) or a §401(a) trust is not treated as a PFIC shareholder.

What is not clearly protected:

• Roth IRA tax-free status in Italy. The treaty does not mention Roth accounts, and no Italian guidance on whether qualified Roth distributions are taxable to an Italian resident was found. (Italian treatment of Roth IRA distributions not found in Agenzia delle Entrate sources reviewed.)
• Italian reporting of U.S. retirement accounts during accumulation (quadro RW / IVAFE). (Whether and how U.S. 401(k)/IRA balances are reportable or subject to IVAFE was not confirmed in primary Italian sources.)
• New IRA contributions while using the FEIE. Income excluded under the FEIE does not count as compensation for IRA purposes. (MyExpatTaxes; Pub. 54 has a section "Contributions to IRAs" whose text was not retrieved.)

Italian investments: PFIC risk, local savings and pensions

For the full mechanics of the default §1291 regime, the QEF and mark-to-market elections, and Form 8621 reporting, see our guide on PFICs.

Italian and EU funds → PFIC. A foreign corporation is a PFIC if 75% or more of its gross income is passive or at least 50% of its assets produce passive income (Form 8621 instructions). Pub. 54 warns that individuals owning a mutual fund or ETF not domiciled in the United States may have a Form 8621 obligation. Without an election, gains and "excess distributions" are allocated across the holding period, taxed at the highest rate for each prior year and charged interest (§1291). Elections exist (QEF if the fund provides an annual information statement; mark-to-market for marketable stock), but must be made timely.

Small-holding exception. You need not complete Part I of Form 8621 for a §1291 fund if aggregate PFIC holdings are $25,000 or less ($50,000 joint) at year-end and you had no excess distribution or disposition gain (Form 8621 instructions).

Bank deposits and conti deposito. Interest on ordinary Italian bank or deposit accounts is ordinary interest income for U.S. purposes and is not a PFIC issue; the accounts are reportable on FBAR (and Form 8938 above thresholds).

Italian pension funds (fondi pensione) and TFR.

• For FATCA purposes, Annex II of the U.S.–Italy intergovernmental agreement reportedly treats Italian-law retirement and pension funds as exempt, subject to limits on voluntary contributions. (Law-firm summary of the IGA (findknowdo.com) and International Tax Review; Treasury's IGA text was not retrieved.)
• FATCA exemption does not determine U.S. income tax treatment. How the U.S. taxes contributions to, growth in, and distributions from an Italian fondo pensione for a U.S. citizen working in Italy was not found in the sources reviewed. Article 18(6) does not appear to help here, because it covers a plan of one country used while working in the other country. (No IRS guidance specific to Italian fondi pensione located.)
• A reporting exception exists for PFICs held through an arrangement treated as a foreign pension fund under a U.S. income tax treaty (Treas. Reg. §1.1298-1(c)(4), cited in the Form 8621 instructions). Whether Italian fondi pensione qualify under the U.S.–Italy treaty was not confirmed.

Italian cash-value life insurance (polizze vita, unit-linked). Foreign-issued life insurance or annuity contracts with a cash value are reportable on both Form 8938 and FBAR (IRS comparison chart). The treaty covers the U.S. excise tax on premiums paid to foreign insurers, subject to a reinsurance condition (Art. 2(2)(a); Protocol Art. 1(3)). (Income tax treatment of Italian unit-linked policies (including whether underlying funds are PFICs) not confirmed in primary sources.)

FBAR, FATCA and banking in Italy

FBAR (FinCEN Form 114). Required if the aggregate value of your foreign financial accounts exceeds $10,000 at any time during the calendar year; filed electronically with FinCEN, not the IRS; due April 15 with an automatic extension to October 15 (IRS Form 8938/FBAR comparison; Pub. 54). Accounts where you have only signature authority are generally included.

Form 8938. Filed with your Form 1040. For taxpayers living outside the U.S.: more than $200,000 at year-end or $300,000 at any time (single / MFS); more than $400,000 at year-end or $600,000 at any time (married filing jointly). Penalty up to $10,000, plus up to $50,000 more for continued failure after IRS notice (IRS comparison chart).

Italian asset	FBAR	Form 8938
Italian bank / postal account	Yes	Yes
Italian brokerage account	Yes (account only)	Yes (account only)
Italian mutual funds held directly	Yes	Yes
Italian cash-value life insurance / annuity	Yes	Yes
Italian real estate held directly	No	No
INPS (state social security) entitlement	No	No

Italy's mirror-image obligations. Italian residents report foreign financial assets and foreign real estate on quadro RW of the Modello Redditi, which is also used to compute IVAFE (generally 0.2% of the value of foreign financial products; a fixed €34.20 per foreign current or savings account, reportedly due only when average balance exceeds €5,000) and IVIE (1.06% of foreign real estate value, raised from 0.76% from 2024). For an American in Italy, "foreign" means your U.S. accounts and property. (Agenzia delle Entrate Interpello 386/2019 as summarized by IPSOA; rates as reported by fiscoetasse.com and investireoggi.it; primary Agenzia pages and DL 201/2011 text not retrieved.)

Banking access. Italy signed a Model 1 FATCA intergovernmental agreement with the United States on January 10, 2014, under which Italian financial institutions report U.S. persons' accounts to the Italian government for transmission to the IRS. (International Tax Review list of IGAs; Treasury's FATCA page not retrieved.) Expect Italian banks to ask for U.S. tax identification (and self-certification) when you open an account. Whether Italian banks restrict account opening for U.S. persons was not found in the sources reviewed.

U.S. state income tax

The treaty does not protect you from state tax: U.S. state and local taxes are outside its scope except for the non-discrimination article (Technical Explanation, Article 2). Whether a state can keep taxing you after you move to Italy depends on that state's own domicile and residency rules, so the key question is whether you have clearly abandoned your former state domicile. See our guide on state taxes after moving abroad for the framework; check your specific state's rules before your first Italian tax year.

Complete 2026 example — self-employed consultant in Bologna

Profile (illustrative): U.S. citizen only (not Italian), single, Italian tax resident all of 2026, self-employed consultant taxed under ordinary IRPEF (not the forfettario flat regime, not impatriati). Net self-employment profit €60,000. Holds an Italian current account (peak balance €45,000), a U.S. brokerage account ($50,000) and a U.S. checking account (average balance above €5,000). Exchange rate assumed at $1.15 / €1; surcharges assumed at 2.5%.

Step 1 — Social security. As a self-employed U.S. national, SSA assigns U.S. coverage only. She pays U.S. SE tax and obtains a U.S. certificate of coverage for INPS. No INPS contributions are assumed.

Step 2 — Italian income tax.

• IRPEF on €60,000: €6,440 + €7,260 + (€10,000 × 43%) €4,300 = €18,000
• Surcharges (assumed 2.5%): €1,500
• Total ≈ €19,500 ≈ $22,425
• No self-employment detrazione assumed at this income level. (Phase-out of Italian self-employment deductions not confirmed in primary sources.) Whether U.S. SE tax is deductible for IRPEF was not found in the sources reviewed.

Step 3 — U.S. self-employment tax (Schedule SE; not reduced by FEIE or FTC per Pub. 54):

• Net profit: €60,000 × 1.15 = $69,000
• SE earnings: $69,000 × 92.35% = $63,721.50
• Social Security 12.4% = $7,901; Medicare 2.9% = $1,848 → ≈ $9,749
• (Below the 2026 Social Security wage base — that figure was not retrieved for this guide, but the result does not depend on it at this income.)

Step 4 — U.S. income tax with the FTC.

• AGI: $69,000 − half of SE tax ($4,875) = $64,125
• Taxable income: $64,125 − $16,100 = $48,025
• Tax: $1,240 + 12% × $35,625 ($4,275) = $5,515
• FTC: Italian tax ($22,425) exceeds the limitation → U.S. income tax $0; ≈ $16,910 carried forward
• The QBI deduction (§199A) is not assumed; it is generally limited to U.S. trade or business income. (Not confirmed in sources reviewed.)

Step 5 — U.S. income tax with the FEIE instead. Excluding $69,000 also yields $0 U.S. income tax, but no carryforward, and SE tax is unchanged at ≈ $9,749.

Step 6 — Information returns.

• FBAR: yes (Italian account ≈ $51,750 > $10,000).
• Form 8938: no (foreign assets below $200,000 / $300,000 thresholds for filers abroad).
• Form 8621: none (no foreign funds).
• Italy: quadro RW for the U.S. brokerage and checking accounts. IVAFE ≈ €87 on the brokerage account ($50,000 ≈ €43,478 × 0.2%) plus €34.20 on the checking account ≈ €121. (IVAFE rates as above.)

Result: about $9,749 to the U.S. (all SE tax), about €19,600 to Italy (income tax plus IVAFE), and a growing FTC carryforward. Filing deadline: automatic extension to June 15, 2027 for taxpayers abroad, but interest runs from April 15 (Pub. 54).

Common mistakes Americans make after moving to Italy

1. Stopping U.S. filing after becoming Italian resident. The saving clause keeps you in the U.S. system.
2. Paying INPS as a self-employed U.S.-only citizen (or paying both INPS and U.S. SE tax) instead of documenting U.S. coverage with a certificate of coverage.
3. Defaulting to the FEIE out of habit. In high-tax Italy it often forfeits FTC carryforwards and IRA eligibility for no gain — but re-check every year if you claim impatriati.
4. Buying Italian or EU-domiciled funds/ETFs in an Italian brokerage account, creating PFIC exposure and Form 8621 obligations.
5. Assuming the treaty exempts U.S. pensions or Social Security from U.S. tax. For U.S.-only citizens it does not; it changes which country taxes first and how credits work.
6. Forgetting Italy's side of reporting: quadro RW and IVAFE/IVIE apply to your U.S. accounts and U.S. property once you are Italian resident.
7. Counting days loosely. Italy's physical-presence test (from 2024) reportedly counts fractions of days; the FEIE physical-presence test counts only full days.
8. Treating the June 15 automatic extension as interest-free. Interest runs from April 15 (Pub. 54).
9. Missing FBAR because each account is small. The $10,000 threshold is aggregate across all foreign accounts.

Frequently asked questions

Does becoming an Italian tax resident end my U.S. tax obligations?

No. Article 1(2) of the 1999 U.S.–Italy convention lets the U.S. tax its citizens as if there were no treaty, and IRS Pub. 54 confirms worldwide income remains subject to U.S. tax wherever you live.

Is my U.S. Social Security taxed by the U.S., Italy, or both?

Under Article 18(2), social security is taxable only in the recipient's residence state. For a U.S.–Italian dual national resident in Italy, Protocol Art. 1(2)(a) protects that rule from the saving clause, so only Italy taxes it (confirmed by the Treasury Technical Explanation). A U.S.-only citizen remains taxable by the U.S. under the saving clause, with credit relief under Article 23(4).

I'm a self-employed American in Italy. Do I pay INPS or U.S. self-employment tax?

Per SSA's description of the agreement, a self-employed U.S. national who would otherwise be covered by both countries is covered only by U.S. Social Security; dual U.S./Italian nationals working in Italy may elect. U.S. SE tax is not reduced by the FEIE (Pub. 54).

Should I use the FEIE or the Foreign Tax Credit?

At ordinary Italian rates (23%/33%/43% IRPEF plus surcharges for 2026, per secondary sources) the FTC typically eliminates U.S. income tax on Italian earnings and builds carryforwards; the FEIE ($132,900 for 2026, IRS IR-2025-103) does not build carryforwards. Under the impatriati regime, Italian tax may fall below U.S. tax, which can favor the FEIE.

Are my Italian investment funds a problem for U.S. taxes?

Very likely. Non-U.S. mutual funds and ETFs can be PFICs requiring Form 8621 (Pub. 54; Form 8621 instructions). The small-holding exception applies only if total PFIC holdings are $25,000 or less ($50,000 joint) with no excess distributions or sales.

Do I have to report my Italian accounts to the U.S.?

Yes if the aggregate exceeds $10,000 at any time (FBAR), and on Form 8938 if foreign assets exceed $200,000 at year-end or $300,000 at any time ($400,000 / $600,000 joint) for filers living abroad (IRS comparison chart).

When to hire a professional

Get advice from a U.S. preparer experienced with Form 1116/2555 and an Italian commercialista if you:

• are considering the impatriati or new-resident flat-tax regime, or are in your first or last year of Italian residence;
• are self-employed and need a certificate of coverage, or are a dual national choosing between U.S. and INPS coverage;
• hold, or plan to buy, Italian/EU funds, ETFs, unit-linked policies or fondi pensione;
• will take distributions from a 401(k), IRA or Roth IRA while resident in Italy, or receive TFR after leaving Italy;
• are a green-card holder considering a treaty tie-breaker position;
• have unfiled FBARs or prior-year returns (see our guide on Streamlined Filing Compliance Procedures if that applies to you);
• face an Italian assessment inconsistent with the treaty (the mutual agreement procedure has a three-year filing window under Article 25(1)).
