INPS Italy: Italian social security, pensions, and US expat tax obligations in 2026

INPS – Istituto Nazionale della Previdenza Sociale – is Italy’s national social security institution. It manages public pensions, disability benefits, unemployment insurance, and parental leave for tens of millions of workers in Italy.

If you are a US citizen or green card holder who works and pays into INPS in Italy, the contributions have direct consequences for your US tax return – from self-employment tax to foreign pension reporting and FBAR compliance.

The combined employer-employee INPS rate for employees runs at approximately 33% of gross wages – 23.81% from the employer and 9.19% from the employee – among the highest in Europe

For Americans in Italy, the question is not just how much INPS costs, but whether you also owe US Social Security tax on the same earnings, how to report INPS pension income to the IRS, and which treaty provisions can prevent double taxation.

What is INPS in Italy?

INPS is the Italian equivalent of the US Social Security Administration, and contributions made to it have direct implications for American expats’ US tax filings.

It is the single institution that administers social security in Italy for the vast majority of workers – INPS collected EUR 214.6 billion in contributions and paid out EUR 269.6 billion in pension benefits in 2023, according to its own financial report.

INPS’s core functions include:

• Public retirement, disability, and survivor pensions
• Unemployment insurance and short-time work benefits
• Maternity, paternity, and parental leave payments
• Sickness and injury benefits for covered workers

The full Italian name is INPS – Istituto Nazionale della Previdenza Sociale. INPS is administered by the Italian government under the supervision of the Ministry of Labour and Social Policies.

The meaning of INPS in Italy goes beyond pensions. For US expats, any income or benefits flowing through INPS can trigger US reporting obligations – on Form 1040, on the FBAR, and potentially on Form 8938.

How the Italian pension system works: an overview

Italy operates a notional defined-contribution public pension system, meaning your eventual benefit is calculated based on lifetime contributions indexed to GDP growth.

The most common type of pension in Italy – the mandatory INPS public pension – was reformed in 1995 under Law 335 and has been adjusted several times since.

The Italian pension framework rests on three pillars:

1. Mandatory public pension via INPS. This is the foundation. All workers – employees, self-employed, and freelancers – contribute to INPS, and the public pension is the primary source of retirement income for most Italians. The statutory retirement age and minimum contribution thresholds are set by Italian law and subject to periodic reform.
2. Occupational supplementary funds. Employer-sponsored or sector-specific funds that supplement the public pension. Contributions are often matched by employers and receive favorable Italian tax treatment – deductible up to EUR 5,300 per year for 2026 (up from EUR 5,164.57 in prior years), under Legge di Bilancio 2026 (Legge 199/2025), which raised the limit set by Article 8, paragraph 4 of Legislative Decree 252/2005.
3. Individual private pension plans. Voluntary private savings products. These are less common than in the US but increasingly used by younger workers, since the NDC system’s expected replacement rate – roughly 50–60% of final salary for workers under the contributivo system – often falls short of pre-retirement income.

The statutory retirement age under the current framework is 67 with at least 20 years of contributions, though early retirement pathways exist for workers with 42+ years of contributions. These thresholds are updated periodically based on life-expectancy data.

For US expats, the key distinction is between mandatory pensions in Italy administered by INPS and private or occupational funds that may have different US reporting treatment under FBAR and FATCA.

Who must contribute to INPS in Italy?

Any person – regardless of nationality – who earns employment or self-employment income in Italy is generally required to contribute to INPS.

The following four categories of workers must contribute:

• Italian employees. Contributions are split between employer and employee and withheld from gross wages each pay period.
• Self-employed individuals and freelancers. This includes those registered with separate INPS funds like the Gestione Separata, Italy’s fund for freelancers and contract workers not covered by a professional order’s own pension fund.
• Foreign nationals legally working in Italy. A German engineer, a Brazilian consultant, or a Japanese teacher working in Italy all contribute to INPS under the same rules as Italian workers.
• US citizens residing and working in Italy. The obligation is the same, but the US-Italy Totalization Agreement may exempt you from dual contributions if your situation qualifies.

What is INPS in Italy for foreigners?

If you earn income in Italy, you likely owe INPS contributions – unless a totalization agreement or specific exemption applies. The obligation is based on where you work, not where you hold citizenship.

INPS contribution rates: employee, employer, and self-employed

INPS contributions for employees total 33% of gross wages – 23.81% from the employer and 9.19% from the employee – making it one of the higher social security burdens in the EU.

Depending on sector and company size, employer-side ancillary funds (unemployment insurance, sickness, and maternity contributions among them) can push the employer’s total INPS-related cost somewhat above 23.81%

Exact rates are set annually by Italian law and vary by sector, collective bargaining agreement, company size, and employee classification. The figures below reflect the general framework; readers should verify current rates with an Italian payroll specialist.

 

NOTE! Collaboratori (co.co.co and similar parasubordinate workers) pay a higher rate of roughly 33–35% under the same fund. Most US expat freelancers register as professionisti (with a partita IVA), not collaboratori, so the ~26% rate above is the one that applies to them.

The income cap for Gestione Separata INPS purposes is EUR 122,295 for 2026. Contributions are not due above that ceiling.

The INPS employee contribution rate in Italy for 2026 follows the same structure as prior years, though exact percentages are confirmed annually by INPS circular.

For US expats, the critical question is not just the Italian rate but whether you also owe US self-employment tax on the same earnings.

The US-Italy Social Security Totalization Agreement explained

The US and Italy signed a Totalization Agreement that entered into force on November 1, 1978 – the first such agreement the US signed with any country.

It coordinates social security coverage so that Americans working in Italy do not pay into both. The US-Italy Social Security Totalization Agreement has three core effects:

1. Eliminates dual social security taxation. Without the agreement, a US citizen working in Italy could owe both INPS contributions and US self-employment tax on the same income. The agreement assigns coverage to one country’s system.
2. Allows contribution periods to be combined for benefit eligibility. If you have work credits in both the US and Italy, the agreement lets each country count the other’s credits – called “totalizing” – to help you qualify for a partial benefit you might not be eligible for under either system alone.
3. Assigns coverage by nationality, not by the standard 5-year rule – for employees and the self-employed alike. Most US totalization agreements use a 5-year detached-worker exception for temporary employee assignments, then shift coverage to the host country. Italy’s agreement doesn’t work that way for either group: a US national working or self-employed in Italy is generally assigned US coverage regardless of how long the assignment lasts, and dual US-Italian nationals may elect either system.

Under the US-Italy Totalization Agreement, a US citizen working or self-employed in Italy who isn’t also an Italian national generally remains covered by US Social Security rather than INPS, with no time limit on the assignment. This is different from most other totalization agreements, where an employee’s coverage assignment follows the standard 5-year temporary-assignment rule and then shifts to the host country.

For employees, request a certificate of coverage (Form IT/USA 4) from the Italian employer’s provincial INPS office to confirm which country’s system applies to a given assignment.

Employers sending US workers to Italy should request a certificate of coverage from the Social Security Administration to confirm whether US or Italian coverage applies to the assignment.

INPS issues the certificate when Italian coverage applies: for example, for a self-employed dual US-Italian national who elects Italian coverage, or for an employee whose assignment is determined to fall under the Italian system.

See our guide to totalization agreements and how they affect US expat taxes for the broader framework across other agreement countries.

Self-employment tax and INPS: What US expats in Italy must know

A self-employed US citizen in Italy who is covered by INPS under the Totalization Agreement is generally exempt from US self-employment tax on the same earnings – but only if they hold a valid certificate of coverage.

Without that certificate, the IRS default applies: US self-employment tax of 15.3% on net earnings of $400 or more, regardless of any INPS contributions paid in Italy.

The following rules govern the interaction between self-employment tax and INPS in Italy:

• A certificate of coverage is required. To claim exemption from US self-employment tax, you need a certificate from the country providing your coverage. If INPS covers your work, request the certificate from INPS and attach it to your US tax return with Schedule SE each year.
• Gestione Separata registration. Self-employed US expats working in Italy who are covered by the Italian system must register with INPS under the Gestione Separata or applicable fund.
• The FEIE does not reduce self-employment tax. The Foreign Earned Income Exclusion, claimed on Form 2555, reduces your US income tax but has no effect on the 15.3% self-employment tax calculated on Schedule SE. These are separate obligations.
• Double taxation risk without the agreement. A freelancer who fails to invoke the Totalization Agreement and obtain a certificate of coverage may end up paying both INPS contributions in Italy and US self-employment tax on the same income.

Based on a TFX client scenario: A US freelance consultant in Milan earned EUR 85,000 in net self-employment income during 2025. She was paying Gestione Separata contributions in Italy but never obtained a certificate of coverage.

Result: She owed both Italian INPS and US self-employment tax on the same earnings – a combined social security burden of roughly 41% before any income tax. After TFX identified the issue, she obtained the certificate and eliminated the US self-employment tax going forward.

Are INPS contributions tax-deductible on your US return?

INPS contributions paid by a US expat are generally not deductible as a business expense on a US federal return, and they do not qualify for the Foreign Tax Credit under IRC Section 901.

To claim a Foreign Tax Credit on Form 1116, a foreign payment must pass a two-part test:

• The contribution must be a compulsory payment imposed by a foreign government.
• The payment must qualify as an income tax or a tax in lieu of an income tax.

INPS contributions meet the first test – they are compulsory – but generally fail the second. Social security contributions fund specific benefits like pensions, disability, and unemployment insurance. The IRS treats them as social insurance payments, not income taxes.

IRS Publication 514 specifically bars a credit or deduction for Social Security taxes paid to a country with which the US has an active Totalization Agreement.

This means Italian income taxes paid on wages or self-employment income – IRPEF and regional/municipal surtaxes – are generally creditable on Form 1116. INPS tax in Italy – meaning the social security contribution itself – is not.

This is a nuanced area. If you are claiming the Foreign Tax Credit on Italian income, work with a tax professional to separate creditable Italian income taxes from non-creditable INPS contributions.

See our comparison of the Foreign Tax Credit and the Foreign Earned Income Exclusion for the broader decision framework.

Foreign Tax Credit vs. Foreign Earned Income Exclusion: Which applies to INPS?

The Foreign Tax Credit addresses different parts of the US-Italy tax overlap – and neither one directly offsets INPS contributions

• The FEIE excludes qualifying foreign earned income from US taxation. For tax year 2025, the maximum exclusion is $130,000 per qualifying person, claimed on Form 2555. The FEIE reduces your US income tax, but it does not reduce INPS contributions – those are determined by Italian law and are separate from US tax relief.
• The Foreign Tax Credit offsets Italian income taxes paid. Form 1116 can reduce your US tax liability dollar-for-dollar by the amount of qualifying Italian income taxes – IRPEF and surtaxes – you paid. It does not apply to INPS contributions, which the IRS does not treat as creditable income taxes.

Choosing the FEIE over the Foreign Tax Credit can sometimes leave US expats in Italy with a higher net tax burden if significant Italian income taxes – separate from INPS – are also in play.

Italy’s IRPEF rates range from 23% to 43% for 2026, which often exceeds US effective rates on the same income. In that scenario, the FTC may generate more US tax relief than the FEIE.

 

See our guide to the Foreign Earned Income Exclusion for the full Form 2555 mechanics.

Form 2555 must be filed with your Form 1040 to claim the exclusion.

See our guide on where to report foreign income on Form 1040 for the line-by-line instructions.

FBAR and FATCA reporting for INPS accounts: What you need to know

Whether an INPS pension account must be reported on an FBAR or Form 8938 depends on whether it constitutes a foreign financial account – a question that turns on the nature of the benefit and IRS guidance on foreign social security equivalents.

The key reporting rules are:

• FBAR threshold. US persons must file FinCEN Form 114 if the aggregate value of their foreign financial accounts exceeds $10,000 at any point during the year. The FBAR deadline for tax year 2025 is April 15, 2026, with an automatic extension to October 15, 2026.
• Government-administered social security accounts are generally exempt from FBAR. The FBAR rules only reach accounts held at a financial institution. A mandatory first-pillar INPS pension entitlement is a government-administered social insurance benefit, not an account at a bank or investment firm, so it generally falls outside FBAR’s definition of a foreign financial account.
• Private supplementary pension funds in Italy may not be exempt. Italian occupational pension funds and private pension plans – the second and third pillars – are held at financial institutions and may qualify as foreign financial accounts for FBAR reporting. If the aggregate value of all your foreign accounts, including these funds, exceeds $10,000, you file the FBAR.
• Form 8938 thresholds vary by filing status and residency. For a single US expat living abroad, the Form 8938 threshold is $200,000 at year-end or $300,000 at any point during the year. For married filing jointly abroad, it is $400,000 at year-end or $600,000 at any point.

 

See our detailed guide to FBAR filing requirements for the complete rules.

Form 8938 and Italian pension accounts

Form 8938 is filed with your annual Form 1040 and applies to specified foreign financial assets above the applicable threshold. The threshold varies by filing status and whether you live inside or outside the US.

A private Italian pension fund is likely a specified foreign financial asset requiring Form 8938 disclosure if it exceeds the applicable FATCA threshold.

Foreign social security entitlements administered by a foreign government – like the INPS first-pillar pension – are generally not reportable on Form 8938. But Italian occupational pension funds and private pension accounts held at financial institutions likely are.

The distinction matters because FATCA penalties for non-filing can reach $10,000 per failure, with additional penalties up to $50,000 for continued non-compliance after IRS notice.

See our guide on FATCA exemptions and which accounts are exempt from reporting.

How Italian INPS pensions are taxed in the United States

Under the US-Italy Tax Treaty, Italian pension income paid to a US resident is generally taxable only in the US, while pensions paid to an Italian resident may be taxable only in Italy – making residency the determining factor.

The treaty’s pension article – Article 18 – governs which country has primary taxing rights.

Article 18 of the US-Italy Tax Treaty works as follows:

• Pensions derived by a resident of one country in consideration of past employment are taxable only in that country.
• Social security payments – including INPS pensions – are covered directly by Article 18, paragraph 2 of the current US-Italy Tax Treaty, in force since December 16, 2009. That paragraph states that social security payments are taxable only in the recipient’s country of residence.
• The savings clause in Article 1, paragraph 2 allows the US to tax its own citizens as if the treaty did not exist. Because Italy pays the INPS pension to its own resident rather than to a resident of the other country, Article 18’s cross-border allocation – and the savings-clause exception that protects it – never comes into play here. A US citizen living in Italy who receives an INPS pension generally still owes US tax on it, even if the citizen also holds Italian nationality.

An INPS pension in Italy is generally included in gross income on your US Form 1040. If a treaty exemption applies and you are claiming it, file Form 8833 to disclose the treaty-based return position.

The treaty does not automatically eliminate US taxation for US residents – it allocates taxing rights, and the correct forms must be filed.

See our guide to the US-Italy tax treaty for the complete treaty framework.

The Windfall Elimination Provision and Italian INPS pensions

The Social Security Fairness Act, signed into law on January 5, 2025, permanently repealed the Windfall Elimination Provision.

The repeal is retroactive to benefits payable from January 2024 onward. By July 2025, SSA had completed more than 3.1 million retroactive payments totaling over $17 billion combined for WEP and the related Government Pension Offset (GPO).

Before the repeal, WEP applied when a worker received a pension from employment not covered by US Social Security – such as an INPS pension – and had fewer than 30 years of substantial US earnings.

The formula reduced the worker’s US benefit by substituting a lower percentage in the first band of the benefit calculation. For workers with 20 or fewer years of substantial Social Security-covered earnings, the maximum monthly WEP reduction was $587 in 2024.

For US expats with Italian INPS pensions, this means the WEP concern is gone. If you delayed claiming US Social Security benefits because of WEP, your benefit is now calculated under the standard formula. No action was required – SSA adjusted payments automatically.

Double taxation risk: When both the US and Italy can tax INPS income

Double taxation of Italian INPS income is avoidable in most cases, but only if the correct treaty elections and IRS forms are filed on time. Without proper filings, the same income can be taxed by both countries.

The following four scenarios create double taxation risk between the US and Italy:

• US citizen living in Italy receiving an INPS pension. The treaty may assign taxing rights to Italy under Article 18, but the US still taxes worldwide income unless the treaty position is claimed on Form 8833. Dual US-Italian nationality does not change this outcome for the INPS pension itself; the savings-clause exception applies only to cross-border payments, and Italy is paying its own resident here.
• US resident receiving an INPS pension. The pension is generally taxable in the US. Italian withholding on the pension may be creditable on Form 1116 as a foreign income tax.
• Self-employed expat not covered by the Totalization Agreement. Without a certificate of coverage, you may owe both INPS contributions in Italy and US self-employment tax on the same earnings – the most expensive double-tax scenario.
• Expat who fails to file Form 8833. If you have a valid treaty position but do not disclose it on Form 8833, you lose the treaty protection. The IRS will treat the income as fully taxable under domestic rules.

TFX client scenario

A dual US-Italian citizen living in Rome received both an INPS pension and US Social Security. He never filed Form 8833. The IRS taxed both under standard domestic rules.

Because he held Italian citizenship as well as US citizenship, the treaty’s savings-clause exception protected his US Social Security from US tax under Article 18, paragraph 2 – as a dual national, Italy retained the exclusive right to tax it.

His INPS pension didn’t get the same protection: that exception only covers social security paid by one country to a resident of the other, and Italy pays the INPS pension to its own resident, so the US still had the right to tax it under the savings clause.

TFX filed an amended return with Form 8833 to correct the US Social Security position and claimed a Foreign Tax Credit for the Italian tax paid on the INPS pension.

See our comparison of the Foreign Tax Credit vs. deduction for how to choose the right relief method on Italian income taxes.

INPS and the Foreign Earned Income Exclusion: key interactions

The FEIE, claimed on Form 2555, excludes qualifying foreign earned income from US taxable income. For tax year 2025, the maximum exclusion is $130,000 per qualifying person.

The FEIE interacts with INPS in specific ways that US expats need to understand.

Claiming the FEIE on Italian wages reduces your US income tax bill but has no effect on your INPS contribution liability or on the taxability of future INPS pension payments. INPS contributions are determined by Italian law and are not affected by US tax elections.

INPS pension income received in retirement is not “earned income” – it is pension income. It does not qualify for the FEIE.

Only active wages and self-employment income from services performed abroad qualify for the exclusion. Once you retire and begin receiving INPS payments, the FEIE is no longer relevant to that income stream.

US expat tax compliance checklist for Americans with INPS obligations

Missing even one of these eight steps can result in IRS penalties, lost treaty benefits, or unexpected double taxation.

The following checklist covers the core compliance requirements for Americans with INPS-related obligations.

The eight steps are:

1. Determine your INPS coverage status under the Totalization Agreement. Confirm whether the agreement assigns your coverage to the US system, the Italian system, or gives you an election.
2. Obtain a certificate of coverage if exempt from INPS. If US Social Security covers your work, request the certificate from SSA. If INPS covers your work, request it from INPS. Attach it to your US return.
3. Register with INPS or Gestione Separata if required. If the agreement assigns your coverage to Italy, complete your Italian registration.
4. Report INPS pension income on Form 1040. All INPS pension payments are includable in gross income unless a treaty exemption applies.
5. File Form 8833 if claiming a treaty position. Any reduction of US tax based on Article 18 of the US-Italy tax treaty must be disclosed.
6. Evaluate FBAR and Form 8938 obligations for private Italian pension funds. Public INPS pensions are generally FBAR-exempt, but private and occupational funds likely are not.
7. Calculate Foreign Tax Credit eligibility on Italian income taxes. Italian IRPEF and surtaxes paid on your income are generally creditable on Form 1116. INPS contributions are not.
8. Confirm the WEP repeal applies to your US Social Security benefit. The Social Security Fairness Act permanently repealed WEP in January 2025. Your US benefit is now calculated under the standard formula regardless of your INPS pension.

Based on TFX client experience, Americans in Italy typically need to address at least five of these eight items each tax year. Starting with the Totalization Agreement determination saves the most time and money – it drives the answer to several downstream questions.

From INPS analysis to Form 1040 pension reporting – we handle every piece.

Common mistakes US expats make with INPS and Italian social security

The most costly mistake TFX sees is US expats in Italy paying both INPS and US self-employment tax simultaneously because they never invoked the Totalization Agreement.

This one error alone can add 15.3% of net earnings to your annual tax burden – on top of the Italian social security you are already paying.

The following six mistakes appear most often in TFX client files:

1. Assuming INPS contributions are automatically creditable as foreign taxes on Form 1116. They are not. INPS contributions are social insurance payments, not income taxes, and IRS Publication 514 bars the credit for Social Security taxes paid to a totalization-agreement country.
2. Failing to obtain a certificate of coverage under the Totalization Agreement. Without the certificate, the IRS presumes you owe US self-employment tax. The certificate is the proof that exempts you.
3. Not reporting INPS pension income on Form 1040. All INPS pension payments received by a US person are reportable as foreign pension income – regardless of whether a treaty reduces or eliminates the tax.
4. Incorrectly applying the FEIE to INPS pension payments. The FEIE covers only earned income from services performed abroad. Pension income is not earned income and cannot be excluded on Form 2555.
5. Overlooking the WEP repeal when planning retirement income. WEP was permanently repealed in January 2025. If your US Social Security projections still include a WEP reduction, they are overstating your effective tax rate and understating your benefit.
6. Assuming private Italian pension funds are exempt from FBAR and FATCA. The first-pillar INPS public pension is generally FBAR-exempt. Private occupational funds and individual pension plans held at financial institutions are not.

Based on a TFX client scenario: A US expat approaching retirement in Florence had been paying both INPS and US self-employment tax for six years without a certificate of coverage. TFX identified roughly $68,000 in excess US self-employment tax, obtained the certificate, and amended prior returns to claim refunds on the overpaid SE tax.

INPS for retirees: Collecting your Italian pension from the US

US residents who qualify for an Italian pension can receive payments directly from INPS, but must report those payments as foreign pension income on their US federal tax return each year.

The process involves applying to INPS, meeting proof-of-life requirements, and correctly converting payments to USD for IRS reporting.

Collecting an INPS pension from outside Italy involves three practical steps:

• Applying for INPS benefits from abroad. US residents can file a claim through the SSA under the Totalization Agreement. SSA will forward your application to INPS, or you can contact INPS directly. Each country processes its own claim and sends its own benefit.
• Annual proof-of-life requirements. INPS requires periodic proof that the beneficiary is alive. This is typically handled through a certificate from your local Italian consulate, the paying bank, or a notarized form. Missing the deadline can suspend payments.
• Currency conversion for US tax reporting. Convert each INPS payment to USD using the IRS-approved annual average exchange rate or the spot rate on the date of receipt, whichever method you choose consistently. Report the amount in USD on Form 1040.

The INPS website in Italy – www.inps.it – provides information on benefit applications, payment schedules, and required documentation for international beneficiaries.

The regional INPS office in the province where you last worked in Italy handles claims for benefits earned in that region.

See our guide to Social Security benefits for Americans living abroad for the broader framework on receiving both US and foreign social security payments.
