International Athlete US Tax Guide 2026

For informational purposes only — not financial, tax, legal, or immigration advice. International tax situations are complex; work with a CPA experienced in athlete and cross-border taxation before making any decisions.

The NBA roster has over 100 international players. MLB rosters are roughly 30% foreign-born — the Dominican Republic alone accounts for over 600 players in the major and minor leagues. The NHL has players from 20+ countries. The MLS draws players from Europe, Latin America, and Africa. Professional soccer, tennis, and combat sports bring athletes from every continent to compete and earn in the United States.

Every one of these athletes faces a tax situation that their domestic-born teammates do not: multiple tax systems, US reporting obligations on foreign accounts, potential estate tax exposure on a fraction of what their US-citizen teammates face, and the very real possibility that a country back home wants to tax the same income the IRS is already taxing.

The good news: with the right planning, most of these problems are solvable. The bad news: most international athletes don't learn about them until they've already made the expensive mistakes.

Step 1: How the IRS classifies you

Every person who earns income in the US is either a resident alien or a non-resident alien (NRA) for tax purposes. The classification determines which income the US can tax and which forms you're required to file.

You are a US tax resident if:

• You hold a US green card (lawful permanent resident), regardless of how many days you spend in the US, OR
• You meet the substantial presence test for the calendar year.

The substantial presence test

You meet the test — and become a US resident alien for tax purposes — if you are present in the United States for:¹

• 183 or more days in the current calendar year, OR
• A weighted total of 183 or more days counting: all days in the current year, plus 1/3 of the days in the prior year, plus 1/6 of the days in the year before that.

Days are counted as any day you are physically present in the US — even a partial day counts as a full day. Days in transit (if you don't leave the airport) and days of medical necessity generally don't count. Regular season + playoffs + training camp in the US adds up fast.

Non-resident alien (NRA) status

If you don't have a green card and don't meet the substantial presence test, you're a non-resident alien. NRAs are taxed differently: the US only taxes US-source income. Your French bank account, your Spanish endorsement deal, your apartment in São Paulo — the IRS generally cannot touch those.

Many international athletes in sports with shorter US presence windows — some tennis players, Olympic athletes training abroad — may qualify as NRAs. But any athlete playing a full US professional league season will almost certainly meet the substantial presence test and become a US resident alien.

What US resident alien status means for your taxes

As a US resident alien, you file a Form 1040 (the same return US citizens file) and report your worldwide income. That includes:

• League salary and playoff/championship bonuses
• Endorsement and NIL income (including deals from brands in your home country)
• Investment income from accounts in your home country
• Rental income from property you own in your home country
• Interest on bank accounts anywhere in the world
• Gains from selling assets (real estate, stocks, business interests) abroad

This is the single biggest surprise for most international athletes. They assume "I'm not American, so only my US salary is taxed here." That's NRA treatment. Once you cross the substantial presence threshold, that assumption is wrong — sometimes by hundreds of thousands of dollars per year.

Double taxation relief: the foreign tax credit

The US doesn't require you to pay full tax to two countries on the same income. The Foreign Tax Credit (FTC) allows you to offset US tax liability, dollar-for-dollar, with income taxes paid to a foreign government on the same income.² If France taxes your French bank interest at 30% and your US marginal rate on that income is 37%, you generally pay 30% to France and 7% to the US — not 67%.

The FTC is not automatic and not unlimited — it requires careful carve-outs by income basket (general limitation income, passive income, etc.) and Form 1116 documentation. A CPA who handles cross-border athlete returns will ensure you're not leaving credits on the table.

Tax treaty planning

The United States has income tax treaties with over 60 countries.³ These treaties often reduce or eliminate US tax on specific types of income earned by residents of the treaty country. For international athletes, the most relevant provisions are typically:

• Athletes and entertainers articles: Many treaties let the US tax performance income earned here regardless of the athlete's residency — but may cap withholding rates on other income categories.
• Dividend and interest income: Reduced withholding rates on passive income flowing between countries.
• Pension and retirement income: Some treaties clarify how foreign pension accounts are treated for US tax purposes.

Treaty benefits generally require filing a Form 8833 disclosure with the IRS and meeting treaty definitions. The benefits are real but claiming them wrong — or not claiming them at all — costs money in both directions.

Countries with active US income tax treaties that are commonly relevant to professional athletes include: Canada, Mexico, France, Germany, Spain, Netherlands, Belgium, Italy, Sweden, Denmark, Norway, Finland, Australia, Japan, South Korea, Czech Republic, and many others. If your home country has a treaty, your tax advisor should be running a treaty analysis annually.

FBAR and FATCA: the reporting requirements most athletes miss

Even if you owe zero additional US tax on your foreign accounts (because FTC fully offsets the liability), you may still have mandatory reporting obligations — and the penalties for missing them are severe.

FBAR (FinCEN 114)

If you have signature authority or a financial interest in any foreign bank or financial account, and the aggregate maximum value of all your foreign accounts exceeds $10,000 at any point during the calendar year, you must file an FBAR by April 15 (automatically extended to October 15).⁵

The $10,000 threshold is not per account — it's the aggregate of all accounts. A French checking account at €5,000 plus a Spanish brokerage at €7,000 = €12,000 combined. Above the threshold. FBAR required.

The penalty for a willful FBAR violation is the greater of $100,000 (adjusted for inflation) or 50% of the account balance at the time of the violation — per year, per account. A player with €500,000 across foreign accounts who willfully doesn't file for three years faces penalties that can exceed the account balance. These are not hypothetical penalties — the IRS and DOJ prosecute FBAR cases actively.

Form 8938 (FATCA)

Separate from FBAR, Form 8938 (Statement of Specified Foreign Financial Assets) is filed with your 1040. Filing is required if you are a US resident and your specified foreign financial assets exceed:⁶

• $50,000 at year-end (or $75,000 at any point during the year) for single filers
• $100,000 at year-end (or $150,000 at any point) for married filing jointly

Form 8938 covers a broader definition than FBAR: foreign bank accounts, foreign securities, interests in foreign entities, foreign pension plans, and interests in foreign trusts. The penalty for failure to file when required starts at $10,000, rising to $50,000 for continued non-filing after IRS notice, plus a 40% penalty on any tax underpayment attributable to undisclosed assets.

FBAR and Form 8938 are cumulative — you may need to file both. Many international athletes don't learn this until an IRS notice arrives.

State income tax: the CA and NY traps

International athletes face the same state income tax traps that US-born athletes do — except the stakes are even higher because they often don't know the rules apply to them.

California's 183-day rule and the FTB audit machine

California taxes anyone who is a California resident on their worldwide income. You are a California resident if California is your domicile, or if you spend more than 183 days per year in California and have a "closer connection" to California than to any other state.⁷ An international player who doesn't establish domicile elsewhere, plays for a California team, and stays in the area during off-season is at significant risk of California treatment as a full-year resident — with worldwide income taxation at California's 13.3% top rate.

The California Franchise Tax Board (FTB) is aggressive about auditing athletes and high earners for residency status. Your CPA needs to document your domicile situation carefully before and during any California-based contract.

New York's 183-day statutory resident rule

New York imposes a "statutory resident" rule: if you maintain a permanent place of abode in New York and spend more than 183 days in the state during the year, you are a New York resident for tax purposes — regardless of your domicile.⁸ Keeping an apartment in New York while playing for the Knicks or Yankees and spending a full season there triggers full NY resident treatment on worldwide income at New York's 10.9% top rate, plus New York City tax if you live within the city.

See the Athlete Domicile & Residency Guide for the full domicile checklist applicable to both US and international players.

The estate tax trap for non-resident aliens

This is where international athletes face a hidden risk that their US-born teammates do not: the non-resident alien estate tax.

For US citizens and US resident aliens, the OBBBA (One Big Beautiful Bill Act, July 2025) permanently raised the estate and gift tax exemption to $15 million per person.⁹ A US citizen can pass $15M to heirs completely free of federal estate tax.

For non-resident aliens, the exemption is $60,000 — a threshold that has not been adjusted for inflation since 1976.¹⁰ The 40% estate tax rate applies to all US-situs assets above that $60,000 threshold.

This problem is solvable — but only with planning before death, not after. Common structures include:

• Foreign holding companies: Holding US real estate or securities through a properly structured foreign entity can convert US-situs assets into non-US-situs assets (shares in a foreign company). This is complex and requires careful tax analysis to avoid other traps.
• Estate tax treaties: The US has estate tax treaties with certain countries (UK, France, Germany, Netherlands, Canada, and others) that increase the effective exemption or provide reciprocal treatment. Athletes from treaty countries should analyze treaty benefits with their estate attorney.
• Tenancy-in-common structures: Various strategies for jointly held assets.
• Life insurance: A properly structured offshore or ILIT-held policy can provide liquidity to pay the tax without requiring a fire sale of US assets.

The key point: if you are playing in the US, accumulating assets in the US, and you are not a US citizen or green card holder, you need estate planning for NRAs — not the same estate plan an American athlete uses.

Social Security and the totalization agreements

The US has Social Security totalization agreements with 30 countries, including Canada, Japan, Brazil, Mexico, France, Germany, Australia, and many European countries.¹¹ These agreements prevent dual Social Security taxation — so you don't pay into both the US Social Security system and your home country's equivalent on the same earnings.

For US league athletes, the typical result is that you pay US Social Security taxes on US earnings and your home country's equivalent on home-country earnings, with credits toward benefit eligibility in each system.

If your home country is the Dominican Republic: the US and DR do have a Social Security totalization agreement.¹² But as noted above, there is no income tax treaty — so Social Security is covered but income tax double taxation requires the FTC approach.

Foreign pension accounts: a frequently mishandled item

Many countries have mandatory pension or retirement savings systems — Canada's RRSP, Australia's Superannuation, the UK's National Insurance system, France's pension contributions. If you contributed to any of these before coming to the US or during off-seasons abroad, the US tax treatment of those accounts is not obvious.

The IRS does not automatically recognize foreign retirement accounts as tax-deferred. Depending on the country and the account type:

• Earnings inside the account may be taxable in the US annually (even though they're not taxed in your home country until withdrawal)
• Specific treaty provisions may allow tax deferral until withdrawal — but you have to claim the treaty position each year
• Some accounts are classified as Passive Foreign Investment Companies (PFICs), which carry punitive US tax treatment on gains

The default — doing nothing — often results in the worst tax outcome. Get a CPA with international experience to review every foreign account you hold when you first become a US tax resident.

US immigration status and its tax connection

Most professional athletes entering the US to compete come on a P-1A visa, which is specifically designed for internationally recognized athletes.¹³ The P-1A is a nonimmigrant visa — it does not make you a permanent resident or give you a green card. Athletes can initially be admitted for up to 5 years, extendable to a maximum of 10 years.

On a P-1A visa, you are a nonimmigrant — but that doesn't automatically make you an NRA for tax purposes. If you're physically present in the US for enough days (substantial presence test), you become a US tax resident regardless of your immigration status. Visa category and tax status are determined by completely different rules.

Some athletes eventually pursue permanent residency or US citizenship — through EB-1A (extraordinary ability) green cards or naturalization. The tax implications of becoming a permanent resident are significant: you now owe US taxes on worldwide income indefinitely, and if you later decide to give up the green card, there's an exit tax analysis required under IRC §877A.

The 10 most expensive mistakes international athletes make

1. Assuming only US income is taxable. Once you meet the substantial presence test, you're taxed on worldwide income. Not knowing this until year two of your contract can mean a multi-year back-tax bill with penalties.
2. Not filing FBAR or Form 8938. The penalties are disproportionate to the tax owed. Many athletes owe $0 in additional tax on foreign accounts — but owe six-figure penalties because they didn't file the disclosure form.
3. Not tracking days in the US. The substantial presence test depends on exact day counts. Players who spend offseasons abroad may be below the threshold — but need documentation. Keep a travel log.
4. Ignoring the state residency rules. International athletes often know about federal taxes but don't know that California and New York have their own resident rules that can impose state income tax on worldwide income.
5. Not claiming treaty benefits. Athletes from treaty countries often leave significant money on the table by not filing Form 8833 and claiming available treaty reductions on passive income, endorsement income, or other categories.
6. No estate plan for NRA status. Dying as a non-resident alien with millions in US-situs assets can cost the estate 40% on everything above $60,000. A $15M athlete's estate could lose $6M+ in avoidable estate tax.
7. Defaulting to US-citizen financial advisors who don't know cross-border rules. A financial planner who doesn't understand FTC mechanics, treaty planning, and NRA estate tax exposure can structure an athlete's portfolio in a way that costs millions in preventable tax.
8. Thinking FBAR and Form 8938 cover the same accounts. They overlap but are not identical. Some assets appear on one and not the other. File both if required.
9. Not analyzing foreign accounts for PFIC exposure. Foreign mutual funds, foreign ETFs, and certain foreign pension-like accounts may be classified as PFICs under US law, triggering punitive taxation on gains. A CPA can restructure these before significant gains accumulate.
10. Making residency decisions without a tax advisor. Buying a house in California looks like a lifestyle choice. It can be a tax decision that costs $1M+ per year in California state income tax on worldwide income, depending on your domicile status. Cross-border athletes need their CPA in the room for major life decisions — not just at tax season.

Who to work with

International athletes need two specialists working together:

• A CPA with international athlete experience — someone who handles Forms 1116, 8938, 8833, FBAR, and knows the treaty provisions relevant to your home country. Not a generalist who will "figure it out."
• A fee-only financial advisor with cross-border experience — who can structure your investment accounts, insurance, and estate plan for your NRA status, and who coordinates with your CPA on the annual planning decisions.

The advisor who works with your domestic-born teammates is almost certainly the wrong choice. The cross-border issues — FBAR, FATCA, treaty planning, NRA estate tax — are specialized enough that an advisor without this background will miss things that cost you real money.
