Carlos Alcaraz’s remarkable victory at the French Open 2025 was a historic moment, solidifying his place as one of the sport’s brightest stars. However, the triumph comes with a less celebrated reality: a significant tax bill. Fresh off his stunning comeback against Jannik Sinner, Alcaraz is now navigating the complex world of international taxation, learning that winning big also means paying big.
The Heavy Price of Victory: Double Taxation
Alcaraz, like other professional athletes, faces a unique tax situation due to the global nature of his profession. As a Spanish resident competing in France, his French Open winnings are subject to taxation in both countries.
French Taxes: A Non-Resident Levy
France imposes a non-resident tax on income earned within its borders. For Alcaraz, this means approximately 15% of his $2.9 million prize money, or around $450,000, will go to the French authorities.
Spanish Taxes: Personal Income Tax
Adding to the complexity, Spain also taxes its residents’ global income. Spanish Treasury technicians have confirmed that Alcaraz will be taxed under personal income tax as a professional activity. While the exact rate is still being calculated, it’s estimated to be around 30% of his winnings.
Gestha, the union of Treasury technicians, clarified that Alcaraz “will be taxed under personal income tax as a professional activity, deducting accommodation and stay expenses, expenses incurred for having his team of physical and sports trainers, and other deductible expenses.”
The Double Whammy
The combination of French and Spanish taxes means Alcaraz could potentially lose close to half of his French Open earnings. While the exact figure depends on deductible expenses and other factors, estimates suggest he might have to pay roughly $1.2 million in taxes between both nations.
The Net Result: Still a Grand Prize
Despite the significant tax implications, Alcaraz will still take home a substantial sum. After taxes, his net earnings are estimated to be around $1.8 million. While it’s less than the initial prize money, it remains a considerable reward for his hard work and dedication.
How Taxation Works for Tennis Players
The taxation of tennis players is a complex issue, governed by international tax laws and agreements. Here’s a breakdown of the key principles:
Taxed Where You Play
Generally, tennis players are taxed on their winnings in the country where the tournament is held. This means Alcaraz is responsible for paying taxes in France on his French Open prize money.
Home Country Taxes
In addition to taxes in the host country, players may also be subject to income tax in their country of residence. However, many countries have tax treaties in place to prevent double taxation. These treaties typically provide credits or deductions for taxes paid in other countries.
Deductible Expenses
Players can often deduct expenses related to their professional activities, such as travel, accommodation, coaching fees, and equipment costs. These deductions can help reduce their overall tax burden.
The Monaco Advantage
Some tennis players choose to reside in tax-friendly jurisdictions like Monaco. Monaco does not impose income tax on prize money, making it an attractive option for high-earning athletes. However, relocating to Monaco comes with its own set of considerations, including residency requirements and lifestyle changes.
Expert Insights and Reactions
The tax implications of Alcaraz’s victory have sparked discussions among tax experts and fellow players.
Holger Rune’s Tax Lesson
Danish tennis star Holger Rune took to Twitter to educate fans on the tax realities faced by tennis players. He clarified that players pay tax on their prize money in the country where they play and emphasized the importance of deducting expenses to offset tax obligations.
Sean Packard’s Analysis
Sean Packard, a tax director at OFS Wealth, provided a detailed analysis of Alcaraz’s tax situation to Forbes. He explained that Alcaraz would pay the 45% rate in France while facing Spain’s highest income tax rate of 47%, though Alcaraz would also receive a tax credit for paying France’s levies, meaning Alcaraz would pay a combined income tax of at least 47%. This would reduce his winnings by about $1.38 million to just under $1.6 million.
The Bigger Picture: Prize Money and Wealth
Despite the tax challenges, Alcaraz is already one of the highest-paid tennis players in the world. In 2025, he ranked as the highest-paid tennis player, with $10.3 million from on-court earnings and $32 million off the court. His on-court success and lucrative endorsement deals have positioned him for long-term financial security.
French Open Prize Money Increase
The French Open has been increasing its prize money in recent years. In 2025, the total prize money pool was $65.2 million, a 6.3% increase over the previous year. This increase benefits all players, but it also means higher tax liabilities for the top earners.
Alcaraz’s Bright Future
Carlos Alcaraz’s French Open victory is a testament to his talent, hard work, and determination. While the tax implications may seem daunting, they are a sign of his success and earning power. As he continues to dominate the sport, Alcaraz is poised for even greater achievements, both on and off the court.
