Yes, tennis players pay tax on prize money, and usually in more than one place. Federal law treats a tournament payout as ordinary income from personal services, no different from a consulting fee or a sales commission.1Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined The country hosting the tournament typically withholds tax before the check clears, the player’s home country then taxes the same income as part of their worldwide earnings, and self-employment taxes run on top of that. A $100,000 win never lands in the account as $100,000.
The Host Country Takes Its Cut First
Tax starts before the prize money is even paid out. The country where the tournament is held claims the first right to tax the income, and tournament organizers act as withholding agents for their government. They deduct the tax and wire only the remainder.
In the United States, the default withholding rate on payments to nonresident athletes is 30%.2Office of the Law Revision Counsel. 26 U.S. Code 1441 – Withholding of Tax on Nonresident Aliens A foreign player who wins $500,000 at a U.S. event could see $150,000 held back before receiving anything. The organizer issues Form 1042-S documenting the gross payment and what was withheld.3Internal Revenue Service. About Form 1042-S, Foreign Person’s U.S. Source Income Subject to Withholding
The United Kingdom withholds at the basic income tax rate of 20% on payments to nonresident athletes that exceed the personal allowance.4HM Revenue & Customs. Pay Tax on Payments to Foreign Entertainers and Sportspersons Other countries apply their own rates. The percentages vary; the pattern doesn’t.
Home Country Taxes Worldwide Income
After host countries take their share, the home country wants a full accounting. The United States and most developed nations use a residence-based tax system: citizens and residents owe tax on income earned anywhere in the world. A U.S.-based player must report every dollar won at Roland Garros or the Australian Open on Form 1040, even if the money was paid into a foreign account and already taxed abroad.
Residency status can be contested. Tax authorities look at where a player actually spends time, where they keep a home, and where their primary economic ties are anchored. A player who claims residency in one country but spends most of the year somewhere else may face challenges from both jurisdictions.
Form 2555 allows a foreign earned income exclusion, but it’s designed for people who live and work abroad full-time rather than touring athletes who keep a home in the U.S.5Internal Revenue Service. About Form 2555, Foreign Earned Income For most players, the foreign tax credit does the real work of preventing double taxation.
Self-Employment Tax on Top
Tennis players are independent contractors. No tournament issues a W-2 or withholds payroll taxes for them. So on top of regular income tax, they owe self-employment tax covering both Social Security and Medicare — the full amount that an employer would normally split with a traditional worker.
The self-employment tax rate is 15.3% of net earnings: 12.4% for Social Security and 2.9% for Medicare.6Office of the Law Revision Counsel. 26 U.S. Code 1401 – Rate of Tax For 2026, Social Security tax applies only to the first $184,500 in net self-employment income.7Social Security Administration. Contribution and Benefit Base Medicare has no cap. Players earning above $200,000 (single filers) pay an additional 0.9% Medicare surtax on the excess.8Internal Revenue Service. Topic No. 560, Additional Medicare Tax
The obligation kicks in at just $400 in net earnings for the year, a threshold almost any professional player will clear.9Internal Revenue Service. Instructions for Schedule SE (Form 1040) These taxes are reported on Schedule SE alongside Form 1040. Half of the self-employment tax is deductible as an adjustment to income, which trims the overall bill a little.
Amateur players face the same rules. The IRS doesn’t care about amateur status; if income exceeds the filing threshold ($16,100 for a single filer in 2026), it gets reported.10Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
State “Jock Taxes” for U.S. Events
Foreign withholding isn’t the only surprise deduction. Within the United States, nearly every state that hosts professional sporting events also taxes nonresident athletes who compete there. These are informally called jock taxes.
The calculation typically uses a duty-days formula. If a player spends 10 of 200 working days in a particular state, that state claims 5% of the player’s annual income as taxable within its borders. State income tax rates range from zero in places like Florida and Texas to above 13% in the highest-tax states. A touring player who competes in a dozen states in one year ends up with a patchwork of small state obligations, each of which adds real cost and complexity at filing time.
How Double Taxation Gets Avoided
Without relief, a player could easily pay 50% or more in combined tax on a single tournament check. Bilateral tax treaties between countries divide up taxing rights, and the foreign tax credit is the mechanical fix.
The credit reduces the home-country tax bill by the amount already paid to a foreign government on the same income.11Internal Revenue Service. Foreign Tax Credit If $40,000 was paid to the host country, that $40,000 offsets the U.S. tax liability dollar for dollar. The net effect is that the player pays whichever country’s rate is higher, not both stacked together.
The credit is capped. It cannot exceed the U.S. tax that would apply to the same category of foreign-source income, and the math gets messy when a player earns income in a dozen countries in a year. The credit is claimed on Form 1116.12Internal Revenue Service. Instructions for Form 1116
Not every player qualifies for treaty benefits automatically. Many treaties include Limitation on Benefits clauses to stop residents of third countries from shopping for favorable terms. The player has to certify genuine qualification under the specific treaty between their home country and the host country.13Internal Revenue Service. Claiming Tax Treaty Benefits
Deductible Business Expenses
Because tennis players are self-employed, they can deduct ordinary and necessary business expenses against prize money and other income.14Office of the Law Revision Counsel. 26 U.S. Code 162 – Trade or Business Expenses Deductions are reported on Schedule C and reduce the income subject to both income tax and self-employment tax.15Internal Revenue Service. Instructions for Schedule C (Form 1040)
The biggest categories for touring players:
- Travel: airfare, hotels, and ground transportation for tournaments and training camps. The travel has to be overnight and away from the player’s tax home.16Internal Revenue Service. Publication 334 – Tax Guide for Small Business
- Coaching and training: fees paid to coaches, personal trainers, nutritionists, and sports psychologists, plus gym memberships used for professional training.
- Equipment: rackets, strings, shoes, and performance analysis technology. Expensive items can be deducted fully in the year of purchase using Section 179 depreciation.
- Agent and legal fees: agent commissions and contract negotiation costs are deductible as professional service costs.
- Meals while traveling: business meals are generally 50% deductible.
- Insurance: self-employed health insurance premiums, liability coverage, and career-related disability insurance.
Recordkeeping decides whether these deductions survive an audit. The IRS expects receipts, invoices, and documentation tying each expense to the business. A separate business account and a travel log that distinguishes tournament days from vacation days is the baseline.
Pay Quarterly, Not at Year-End
Because nobody withholds income tax or payroll taxes from prize money, players have to pay throughout the year. The IRS requires quarterly estimated payments from anyone expecting to owe $1,000 or more at filing.17Internal Revenue Service. 2026 Form 1040-ES
For the 2026 tax year, the deadlines are April 15, June 15, and September 15 of 2026, plus January 15, 2027. Missing a deadline triggers an underpayment penalty with interest running from the date each payment was due.18Office of the Law Revision Counsel. 26 U.S. Code 6654 – Failure by Individual to Pay Estimated Income Tax
To avoid the penalty, a player has to pay at least 90% of current-year tax liability or 100% of the prior year’s tax through the quarterly installments. If prior-year adjusted gross income was over $150,000, the requirement rises to 110% of last year’s tax.17Internal Revenue Service. 2026 Form 1040-ES Prize money’s unpredictability is the problem here. A player who has a breakout season and suddenly earns far more than last year has to adjust estimates aggressively or take the penalty.
Endorsements Are Taxed Differently
Prize money is only one piece of top-player income. Endorsements, appearance fees, and sponsorships have their own sourcing rules, and the tax treatment depends on what the sponsor is really paying for.
If a sponsor pays a player to film a commercial or make promotional appearances, that’s compensation for personal services, taxed where the work is done. If the deal instead pays for use of the player’s name and likeness — a logo on shoes sold worldwide, for example — the income is characterized as royalty income and sourced based on where products are sold or the image is used. Courts have scrutinized these arrangements, sometimes recharacterizing what a contract labels as royalty income as service income when the payments are actually tied to tournament performance or rankings.
The practical result is that endorsement income often splits across multiple jurisdictions, with each country claiming a slice based on where the player performed or where products generated revenue. Careful contract structuring matters.
Why Monaco Only Partly Helps
A lot of top players list Monaco, Dubai, or the Bahamas as their legal residence. Monaco charges no personal income tax, and several other jurisdictions take the same approach. Genuine residency in one of those places eliminates the home-country tax layer, at least in theory.
In practice, the savings are smaller than people assume. Source-country withholding still applies everywhere a player competes. A Monaco-based player winning a tournament in New York still pays U.S. federal tax (withheld at 30% for nonresidents) plus New York state and city taxes on that income.19Internal Revenue Service. NRA Withholding The same happens in the UK, France, Australia, and every other country that taxes athletes at source. What the Monaco resident avoids is the second layer — the home-country tax on worldwide income that would otherwise stack on top.
U.S. citizens get no benefit from this strategy. The United States is one of the few countries that taxes citizens on worldwide income regardless of where they live. An American player based in Monaco still files a U.S. return and owes U.S. tax on everything earned globally, with foreign tax credits offsetting what was already paid abroad.11Internal Revenue Service. Foreign Tax Credit French nationals who move to Monaco face a similar restriction under a bilateral agreement that keeps them subject to French income tax. The residency strategy works best for players whose home countries use purely territorial or residence-based systems and don’t impose exit taxes.
