Expat Tax Statistics 2026

Q: How many US citizens live abroad in 2026?

The American Citizens Abroad organization estimates approximately 5.5 million US citizens living abroad as of 2024, excluding military personnel and families. The Federal Voting Assistance Program separately estimated 4.4 million US citizens overseas in 2022, of whom 2.8 million were voting-age. The State Department retired its long-cited 9 million estimate in 2024, noting that US citizens are not required to register their overseas presence.

Q: How many US expats claim the Foreign Earned Income Exclusion?

According to the IRS Statistics of Income, approximately 471,000 individual taxpayers filed Form 2555 for tax year 2021, excluding around $36 billion in foreign earned income. The exclusion cap for 2026 is $132,900 per qualifying individual, up from $130,000 in 2025. Filers must meet either the bona fide residence test or the 330-day physical presence test. Many expats use the Foreign Tax Credit (Form 1116) instead, especially in high-tax host countries.

Q: Where do these expat tax statistics come from?

Primary sources include the US Treasury Federal Register quarterly publications under IRC Section 6039G, the IRS Statistics of Income division for Form 2555 FEIE filings, the IRS Data Book for audit volumes, the IRS Tax Treaty A-to-Z list for treaty network coverage, the Federal Voting Assistance Program 2022 Overseas Citizen Population Analysis, the American Citizens Abroad / AARO overall population estimate, and the Greenback Expat Tax Services 2024 and 2025 trends surveys for attitudinal data.

The American Citizens Abroad organization estimated approximately 5.5 million US citizens living overseas in 2024, the Treasury's Federal Register lists totaled 4,475 published expatriations for calendar year 2024, and Greenback's 2025 expat survey found 49% of US expats are considering renunciation, up from 30% the year before. The IRS Statistics of Income shows about 471,000 Form 2555 filers excluded roughly $36 billion of foreign earned income in tax year 2021. This report compiles 13 verified statistics from the IRS, Treasury Federal Register, US State Department, FVAP, Greenback Expat Tax Services, and the OECD covering the US expat tax landscape in 2026.

US expat tax compliance is unusual in the developed world. The United States is one of two countries (Eritrea is the other) that taxes its citizens on worldwide income regardless of where they live. The result is a system where millions of Americans abroad owe US returns even in years they pay zero US tax, while host-country obligations stack on top.

This post focuses on what is measurable. The size of the expat population, the volume of US tax forms actually filed, the renunciation trend documented quarter by quarter in the Federal Register, audit posture per the IRS Data Book, and the most recent attitudinal surveys of US expats. Sources are primary government records wherever they exist, with one major industry survey of 1,145 Americans where the data is attitudinal.

TL;DR: Five headline numbers for 2026

About 5.5 million US citizens live abroad per the American Citizens Abroad 2024 estimate; the FVAP separately estimated 4.4 million overseas US citizens in 2022, with 2.8 million of voting age (AARO, FVAP 2022 OCPA Report).
4,475 published expatriations in 2024, with a Q3 spike of 2,123 alone representing 44% of the year's total (Federal Register Q3 2024).
Approximately 471,000 Form 2555 filers excluded around $36 billion in foreign earned income in tax year 2021 (IRS SOI).
49% of US expats are considering renunciation in 2025, up from 30% in 2024 (Greenback 2025 Survey).
The FEIE cap for tax year 2026 is $132,900 per qualifying individual, up from $130,000 in 2025 (IRS via Greenback inflation summary).

Why these numbers matter in 2026

Three things changed between 2023 and 2026. First, the State Department dropped its long-cited "9 million Americans abroad" figure, leaving non-governmental sources to estimate the population. Second, FATCA and the OECD's Common Reporting Standard have made the foreign-account reporting infrastructure routine, so non-filing is increasingly visible to the IRS. Third, expat sentiment toward US citizenship has measurably soured in the latest surveys, with renunciation consideration climbing sharply.

Below are the figures most relevant to digital nomads, retirees abroad, dual citizens, and anyone evaluating whether to keep or shed US tax obligations. Where a number is from a survey rather than a government file, the methodology is stated up front.

1. About 5.5 million Americans live abroad per AARO's 2024 estimate

The Association of Americans Resident Overseas (AARO) estimated approximately 5.5 million US citizens living abroad in 2024, excluding US military personnel and their families. AARO's number replaces the long-used State Department figure of 9 million, which State formally retired in 2024 with a note that "U.S. citizens are not required to register their presence abroad."

The Federal Voting Assistance Program's 2022 Overseas Citizen Population Analysis separately estimated 4.4 million US citizens overseas in 2022, of whom 2.8 million were 18 or older and eligible to vote. FVAP found this represented an increase of nearly 1.3 million (42%) since 2010.

For US tax purposes, every one of these citizens is in principle required to file a US return if they meet ordinary filing thresholds, regardless of host country tax obligations.

2. Mexico hosts roughly 1.6 million US citizens, more than any other country

The US Department of State has historically estimated approximately 1.6 million US citizens living in Mexico, the largest single concentration of Americans abroad. Canada follows with just over 1 million. The United Kingdom is third with about 325,000.

The full top-ten list (per a 2023 country breakdown summarised by AARO) is Mexico, Canada, the United Kingdom, Israel (around 281,000), Germany (about 239,000), Australia (218,000), South Korea (129,000), France (117,000), Japan (111,000), and Spain (109,000). These ten countries account for most of the documented US expat population.

For US tax administration, the distribution matters. The largest concentrations are in countries where the US has comprehensive tax treaties (Canada, UK, Germany, France, Japan, Spain) or close immigration ties (Mexico). That makes treaty relief and foreign tax credits practically accessible for most expats.

3. Approximately 471,000 Form 2555 filers excluded $36 billion in foreign earned income

According to the IRS Statistics of Income (SOI) division, roughly 471,000 individual taxpayers filed Form 2555 for tax year 2021, the most recent year SOI publishes full Foreign Earned Income data. Those filers excluded approximately $36 billion of foreign earned income under IRC Section 911. SOI publishes the underlying tables as Excel files; tax year 2021 data is the most recent release as of early 2026.

The FEIE is not the only path to avoiding US tax on foreign-source income. Many expats use the Foreign Tax Credit (Form 1116) instead, especially in high-tax host countries like Germany or the UK where the foreign credit fully offsets US liability. SOI publishes Form 1116 data on the same schedule.

The number of FEIE filers has been stable in the 450,000 to 500,000 range for several years. Set against an estimated expat population in the millions, the gap suggests substantial non-filing or use of foreign tax credits in lieu of FEIE.

4. The FEIE cap rose to $132,900 for tax year 2026

The Foreign Earned Income Exclusion is capped at $132,900 per qualifying individual for tax year 2026, up from $130,000 in 2025 and $126,500 in 2024. The cap is adjusted annually by the IRS for inflation under IRC Section 911(b)(2)(D). A qualifying married couple where both spouses meet the bona fide residence or 330-day physical presence test can together exclude up to $265,800 for 2026.

The exclusion does not eliminate the filing requirement. A US citizen abroad with earnings above the standard deduction must still file Form 1040 and attach Form 2555 to claim the exclusion. Income above the cap is taxed normally, and the FEIE does not apply to passive income (dividends, interest, capital gains, rental income), which falls under the Foreign Tax Credit or general US rules.

For 2026, the foreign housing exclusion adds approximately $21,264 to the base exclusion for taxpayers meeting the housing rules.

5. Treasury published 4,475 expatriations in calendar year 2024

The Treasury Department publishes a quarterly list under IRC Section 6039G of US citizens and long-term residents who chose to expatriate. Aggregating the four 2024 quarterly Federal Register notices gives 4,475 published names for calendar year 2024, a 44% increase over the 3,115 published in 2023.

The annual breakdown by quarter was striking. Q1 2024 published 345 names. Q2 published 1,717. Q3 published a single-quarter record of 2,123, accounting for 44% of the year. Q4 published 635. Q3 2024 was the highest single quarter since late 2016 and reflects both the post-pandemic processing backlog clearing and a sustained behavioural rise.

The list captures expatriations the Treasury chose to publish, primarily covered expatriates and long-term residents meeting Section 6039G triggers. The actual number of Americans renouncing each year is likely higher than the published list.

6. 2024 was up 44% from 2023; the decade has averaged 3,000 to 6,000 published expatriations a year

Annual published expatriations under Section 6039G across the last decade: 4,281 (2015), 4,046 (2016), 5,132 (2017), 4,374 (2018), 2,071 (2019), 6,705 (2020), 2,426 (2021), 3,816 (2022), 3,115 (2023), 4,475 (2024). The 2020 figure remains the decade high, driven by pandemic-era backlog processing. 2024's 4,475 sits in the upper half of the range.

The volatility is largely administrative rather than behavioural. Treasury publishes when it receives the information from the State Department and IRS, and processing lags of 12 to 18 months are common. The trend over the decade is clear: published expatriations have not returned to pre-2014 levels, when annual totals ran in the hundreds.

The single-quarter 2,123 in Q3 2024 was the highest since Q4 2016 (2,364). The post-pandemic period has produced consistently higher absolute volumes than the early 2010s.

7. 49% of US expats are considering renouncing citizenship in 2025, up from 30% in 2024

Greenback Expat Tax Services' 2025 trends survey of 1,145 Americans (719 expats, 426 general-population) conducted February to March 2025 found 49% of US expats are planning to or seriously considering renouncing US citizenship, up from 30% in the prior year's survey. That is a 63% year-over-year increase in renunciation consideration.

The 2025 cohort breaks down sharply by demographic. 60% of Millennial expats and 54% of Gen X expats said they were considering renunciation. 71% of expat parents with children under 18 reported considering it. India-based expats reported the highest country-level rate at 93%, though that subgroup is small.

Consideration is not action. Actual published expatriations in 2024 totaled 4,475. The gap between attitudinal interest and follow-through is large, as expected for a one-way, expensive, and irrevocable decision.

8. 55% of expats do not know about the IRS Streamlined Filing Procedures

The same 2025 Greenback survey found 55% of US expats are not aware that the IRS offers Streamlined Filing Compliance Procedures, the principal program for delinquent expat filers to come into compliance without standard penalties. That figure was up from 45% in 2024.

The Streamlined Procedures have existed since 2012 and were significantly expanded in July 2014. The program requires three years of amended returns, six years of FBARs, and a non-willfulness certification. There is no civil penalty for non-willful failures filed under the program.

The awareness gap matters because the alternative for a delinquent filer is the standard penalty regime: up to $10,000 per FBAR for non-willful violations, escalating sharply for willful conduct, plus interest and penalties on unpaid US tax. Streamlined eliminates most of that for taxpayers who qualify.

9. 60% of expats say FATCA has made it harder to maintain foreign bank accounts

The 2025 Greenback survey found 60% of US expats said FATCA makes maintaining bank accounts in their host country more difficult, and 67% described foreign banking laws (FATCA, CRS, host-country reporting) as a source of stress. In the 2024 survey, 38% had reduced or eliminated certain financial products specifically to simplify compliance, with 28% simplifying their portfolio and 25% altering investment strategies.

FATCA, enacted in 2010, requires foreign financial institutions to report US account holders to the IRS or face 30% withholding on US-source income. The practical consequence has been many foreign banks declining US-person accounts entirely to avoid the compliance burden.

For digital nomads, this surfaces as account closures, refused opening applications at certain EU and Swiss banks, and added friction opening brokerage accounts as a US citizen abroad.

10. 73% of expats believe the US offers insufficient credits to prevent double taxation

Greenback's 2024 survey of 1,007 American expats found 73% believe the US government provides insufficient credits and deductions to mitigate double taxation. The view was strongest in Australia (82%) and lowest in France (22%), reflecting differences in how generously each country's tax treaty and credit interaction with US tax actually operates.

Approximately 70% of expats surveyed said Americans abroad should be exempt from filing US taxes entirely, the position long advocated by Americans Abroad and several US legislators (the residence-based taxation reform discussion). No legislative change has been enacted as of 2026.

The 2024 survey also found 62% struggle with managing dual tax obligations and 55% cite complex tax laws as an obstacle to compliance.

Source: Greenback — 2024 US Expat Survey Insights

11. 83% of expats find US tax filing stressful

The 2025 Greenback survey found 83% of US expats reported US tax filing requirements as stressful. Specific stressor breakdowns: 53% cited managing dual tax obligations as a top challenge, 51% struggle with understanding complex tax laws, and 27% lack confidence in correctly filing US taxes while abroad.

For comparison, the 2024 survey found 20% lacked confidence filing taxes abroad and 62% struggled with dual obligations. The 2025 numbers represent both an absolute increase in reported stress and a shift in which aspects of compliance bother expats most.

The stress profile aligns with what tax preparers report: clients often discover filing obligations years into their time abroad, accumulate multiple compliance gaps (FBAR, FATCA, state return loose ends), and underestimate the time and cost of getting current.

12. The IRS closed 505,514 individual tax return audits in FY 2024

The IRS Data Book for fiscal year 2024 reports that the agency closed 505,514 tax return audits and recommended over $29.0 billion in additional tax. Across all individual returns, the overall examination rate has held near 0.2% to 0.4% in recent years, near record lows in absolute terms.

The IRS does not separately publish an audit rate for expat returns. International examination capacity sits within the Large Business and International (LB&I) and Small Business / Self-Employed (SB/SE) divisions. Practitioners report the practical expat audit rate runs at or slightly below the overall individual rate, with elevated scrutiny on Form 8938 (FATCA) and FBAR non-filers, large FEIE claims without documentation, and missing international information returns (Forms 5471 for foreign corporations, 8865 for partnerships, 3520 for foreign trusts and gifts).

The audit risk asymmetry: low base probability, severe consequences if a missing international information return is found.

13. The United States has bilateral income tax treaties with around 68 countries

The IRS maintains an alphabetical list of active US income tax treaties covering approximately 68 partner countries as of 2026 (excluding the historic USSR entry, the US model treaty template, and the recently terminated Hungary treaty). The network covers most of Europe, the major Commonwealth economies, much of East Asia, and a partial set of Latin American and African jurisdictions.

Treaties matter to expats because they:

Reduce or eliminate double withholding on dividends, interest, royalties, and pensions
Provide tiebreaker rules when both countries assert tax residency
Restrict the home country's ability to tax certain income earned in the treaty partner

Notable gaps: there is no US tax treaty with Brazil, Argentina, Singapore, Hong Kong, Saudi Arabia, the UAE, or much of sub-Saharan Africa. Expats in those countries rely on the Foreign Tax Credit rather than treaty relief.

The US-Hungary treaty was terminated effective 1 January 2024 and Belarus / Russia treaties are partially suspended. Coverage is not static.

What these numbers tell us

Three patterns are consistent across the data. First, the US expat population is large but partially uncounted. The ~5.5 million AARO estimate, the ~4.4 million FVAP voting-age figure, and the ~471,000 FEIE filers describe a population where formal IRS engagement is a fraction of the population subject to filing rules. The State Department's decision to retire its 9 million estimate in 2024 makes this clearer, not less so.

Second, sentiment toward US citizenship is measurably worse than two years ago. Renunciation consideration moved from 30% to 49% of surveyed expats in twelve months, against a published expatriation count of 4,475 in 2024. The action-intent gap is wide, but the direction is clear, and the FATCA/banking friction story (60% report account difficulty, 67% find foreign banking stressful) is consistent across both years of the survey.

Third, compliance infrastructure is shifting toward more, not less, information sharing. The CRS for the rest of the world and FATCA for the US mean foreign banks routinely send account data to home tax authorities. The Streamlined Procedures remain the principal soft-landing for delinquent US expats, yet 55% of expats do not know they exist.

For US expats in 2026, the working assumption should be that the IRS will eventually receive your foreign account information, and the only question is whether you brought yourself current first. The Streamlined Procedures exist precisely for the population that wakes up to this fact mid-stream.

How Nomad helps you navigate this landscape

The statistics above describe a population caught between two systems: home-country tax obligations that never end, and host-country residency triggers that depend on physical presence. Day-counting is the connective tissue between the two.

Nomad (the visa compliance app for digital nomads) automates day-counting for both. The app tracks days against the US Substantial Presence Test (the test that creates US tax residency for non-citizens), the 183-day rule used by most countries, the UK Statutory Residence Test, the calendar-year tests used by Spain, Portugal, Germany, France, and Italy, and the rolling 12-month windows used in some treaty contexts. The 330-day Physical Presence Test that qualifies a US citizen for the FEIE is also tracked. Passport details stay on your device.

Frequently Asked Questions

How many US citizens live abroad in 2026?

The American Citizens Abroad organization estimates approximately 5.5 million US citizens living abroad as of 2024, excluding military personnel and families. The Federal Voting Assistance Program separately estimated 4.4 million US citizens overseas in 2022, of whom 2.8 million were voting-age. The State Department retired its long-cited 9 million estimate in 2024, noting that US citizens are not required to register their overseas presence.

How many Americans renounced US citizenship in 2024?

The Treasury Department's Federal Register quarterly publications under IRC Section 6039G listed 4,475 names for calendar year 2024, up 44% from 3,115 in 2023. The third quarter of 2024 alone published 2,123 names, the highest single-quarter total since Q4 2016. The published list captures expatriations the Treasury chose to publish under Section 6039G triggers and likely understates the true number of renunciations.

How many US expats claim the Foreign Earned Income Exclusion?

According to the IRS Statistics of Income, approximately 471,000 individual taxpayers filed Form 2555 for tax year 2021, excluding around $36 billion in foreign earned income. The exclusion cap for 2026 is $132,900 per qualifying individual, up from $130,000 in 2025. Filers must meet either the bona fide residence test or the 330-day physical presence test. Many expats use the Foreign Tax Credit (Form 1116) instead, especially in high-tax host countries.

What percentage of US expats are considering renouncing citizenship?

The 2025 Greenback Expat Tax Services survey of 1,145 Americans found 49% of US expats are planning to or seriously considering renouncing citizenship, up from 30% in 2024. Consideration is highest among Millennials (60%), expat parents with children under 18 (71%), and India-based expats (93%). Actual published expatriations in 2024 totaled 4,475, showing a wide gap between attitudinal interest and follow-through.
