Do other countries pay taxes like the US? Mostly no. The American system stands apart from other developed countries in three big ways: it leans heavily on individual income taxes instead of consumption taxes, it taxes citizens on their worldwide income no matter where they live, and it has no national sales tax. Add in reporting rules for overseas accounts that no other major country imposes, and the differences add up quickly for anyone earning or investing across borders.
Where the Money Comes From
Individual income taxes bring in roughly 40 percent of all US tax revenue. Across OECD countries, the average is about 24 percent. Consumption taxes flip that: they generate only about 17 percent of US revenue versus 31 percent in the typical developed country.1OECD. Revenue Statistics 2025 The US taxes what you earn; most of the world puts more weight on what you spend.
The overall tax take is lower too. The OECD average tax-to-GDP ratio hit 34.1 percent in 2024, and the US sits several points below that.1OECD. Revenue Statistics 2025 Countries with comprehensive public healthcare and larger safety nets often collect 40 percent of GDP or more. Higher taxes fund broader public services; the US model leaves more income in private hands and shifts more of the cost of healthcare and retirement onto individuals.
Progressive Rates Are Common, Flat Taxes Are Rare
The US federal income tax is progressive, with rates from 10 percent at the bottom to 37 percent at the top.2Internal Revenue Service. Understanding Taxes – Theme 3: Fairness in Taxes – Lesson 3: Progressive Taxes Most developed countries do something similar. Canada, the United Kingdom, Germany, and Japan all use progressive brackets, though top rates and thresholds vary considerably.
A smaller cluster of countries uses a flat tax where everyone pays the same rate. Bulgaria applies 10 percent, Hungary 15 percent, and Romania 16 percent. These systems are concentrated in Eastern Europe and were adopted after the fall of the Soviet Union to attract investment and simplify collection. Critics say flat rates hit lower earners harder because essentials eat up more of their income. Supporters argue the simplicity cuts avoidance and administrative cost.
The US Taxes Citizens Wherever They Live
This is the difference that catches Americans off guard when they move abroad. The US and Eritrea are the only two countries that tax based on citizenship rather than residency. Hold a US passport, and you owe the IRS a return on your worldwide income every year, even if you have not set foot in the country for decades.
Every other major economy uses either a territorial system (only income earned inside the country’s borders is taxed there) or a residence-based system (you pay where you live, and when you leave, your obligation ends). Under either of those, moving abroad ends the tie. Under the US approach, an American working in London, Tokyo, or São Paulo files a local return and a US federal return every year. The filing obligation never lifts unless you formally renounce citizenship. Americans abroad do get an automatic extension to June 15 for filing, though interest on any tax owed still runs from the regular April deadline.3Internal Revenue Service.

No National Sales Tax, No VAT
The US is the only major economy without a national consumption tax. Sales taxes are set by states and localities and collected only at the final retail sale. Combined state and local rates run from zero in the five states with no sales tax up to about 10 percent in the highest jurisdictions. The patchwork of thousands of local rates is not something any other developed country replicates.
Over 170 countries use a Value Added Tax instead.4United Nations Department of Economic and Social Affairs (UN DESA). Overview of VAT/GST in Developing Countries VAT is collected at every stage of production, not just the final sale. A manufacturer pays VAT on materials, charges VAT when selling to a wholesaler, and the wholesaler charges it again to a retailer. At each stage, businesses reclaim the VAT they paid on their inputs, so only the value added at that step is effectively taxed. The final consumer bears the full cost, but revenue arrives throughout the supply chain rather than at a single register.
EU standard VAT rates run from 17 percent in Luxembourg to 27 percent in Hungary, with most countries between 19 and 25 percent. Those rates are far above any US sales tax, but they replace or supplement other taxes that the US collects through its income-heavy model.
Corporate Rates Have Converged Around 21 Percent
The US federal corporate tax rate is 21 percent, close to the worldwide average. Across 181 jurisdictions, the unweighted statutory average is about 23.6 percent, and the trend has been down for decades: the global average was above 40 percent in 1980.5Tax Foundation. Corporate Tax Rates Around the World, 2025 The OECD member-country average has settled at roughly 21 percent in recent years.6OECD. New OECD Data Highlight Stabilisation in Statutory Corporate Tax Rates Worldwide
Decades of rate-cutting fueled a race to attract multinational headquarters. To slow it, more than 140 countries agreed through the OECD to a global minimum corporate tax of 15 percent. The rules require large multinational groups to pay a top-up tax in any jurisdiction where their effective rate falls below that floor.7OECD. Global Minimum Tax EU member states have started implementing the framework. The US has been part of the negotiations but its own implementation remains a work in progress.
Payroll Taxes Are Lower in the US Than in Europe
Nearly every developed country funds retirement, disability, and unemployment through mandatory payroll contributions. In the US, employees and employers each pay 6.2 percent of wages toward Social Security, up to a taxable wage base of $184,500 in 2026.8Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Medicare adds 1.45 percent from each side with no earnings cap. Self-employed workers pay both halves, for a combined 15.3 percent up to the Social Security cap.9Social Security Administration. How Is Social Security Financed?
Those rates sound heavy, but the US actually collects a smaller share of total tax revenue from social contributions than the OECD average. In France and Germany, combined employer-employee contributions can exceed 40 percent of wages. The higher rates fund more expansive benefits: universal healthcare, longer parental leave, and more generous unemployment insurance than the US provides.
What Americans Abroad Do Differently
Citizenship-based taxation has practical consequences. Two tools keep worldwide taxation from turning into full double taxation, and two reporting regimes make sure the IRS knows about your foreign accounts.
Foreign Earned Income Exclusion
For 2026, US citizens and resident aliens living and working abroad can exclude up to $132,900 of foreign earned income from US taxable income.10Internal Revenue Service. Inflation Adjustments for Various Code Provisions for 2026 (Rev. Proc. 2025-32) To qualify, you must be a bona fide resident of a foreign country for an entire tax year, or be physically present in a foreign country for at least 330 full days in any 12-consecutive-month period.11Internal Revenue Service. Foreign Earned Income Exclusion – Physical Presence Test The exclusion applies to wages and self-employment income, not to investment returns or pensions.
Foreign Tax Credit
For income above the exclusion, or for investment income the exclusion does not cover, the foreign tax credit offsets your US tax liability dollar-for-dollar against income taxes paid to another country. You claim it on Form 1116, and the foreign tax must have been imposed on you, actually paid or accrued, legally owed, and an income tax.12Internal Revenue Service. Publication 514 (2025), Foreign Tax Credit for Individuals Together the exclusion and credit usually prevent Americans abroad from paying significantly more total tax than they would under a single country’s system. The compliance cost of filing in two jurisdictions is still real.
Totalization Agreements for Social Security
When an American works abroad, both countries may try to collect social security contributions on the same paycheck. Totalization agreements solve this by assigning each worker to one country’s system. The US has these agreements with about 30 nations, covering most of Western Europe, Canada, Australia, Japan, South Korea, and several others.13Social Security Administration. U.S. International Social Security Agreements They also let workers combine credits from both countries to qualify for benefits they would otherwise miss, with each country paying based only on the time worked there. Six quarters of US coverage are needed before US credits can count in a totalization calculation.
FBAR and FATCA Reporting
Citizenship-based taxation also produces reporting duties that have no parallel in other tax systems. If the combined value of your foreign financial accounts exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FinCEN Form 114) by April 15, with an automatic extension to October 15.14Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The FBAR is not a tax form; it is a separate anti-money-laundering filing, and the penalties for skipping it are severe, running into tens or hundreds of thousands of dollars for willful violations.15Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) – IRM 4.26.16
The Foreign Account Tax Compliance Act adds a second layer. Form 8938 kicks in at $50,000 in foreign financial assets at year-end (or $75,000 anytime) for US residents, with much higher thresholds for filers living abroad — $200,000 year-end and $300,000 anytime for single filers, doubled for joint filers.16Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets FATCA also requires foreign banks to report US account holders directly to the IRS. FBAR and FATCA overlap but cover different assets, use different valuation rules, go to different agencies, and carry different penalties. Filing one does not satisfy the other.
An Exit Tax for Giving Up Citizenship
Given all of this, some Americans abroad consider renouncing. The US has a response: an exit tax that treats all your assets as sold at fair market value on the day before you expatriate.17Office of the Law Revision Counsel. 26 US Code 877A – Tax Responsibilities of Expatriation Any unrealized gain above an inflation-adjusted exclusion (based on a $600,000 starting figure from 2008) gets taxed as if you actually sold everything.
The exit tax only hits “covered expatriates” — those whose average annual net income tax liability over the prior five years exceeds $211,000 for 2026,10Internal Revenue Service. Inflation Adjustments for Various Code Provisions for 2026 (Rev. Proc. 2025-32) whose net worth is $2 million or more, or who cannot certify under penalty of perjury that they have complied with all federal tax obligations for the prior five years. Fail any one of those tests and the deemed sale applies. No other country imposes anything quite like it on departing citizens, which fits the pattern: in the US, tax follows the passport, not the address.
