Jannik Sinner, after securing his first Wimbledon title with a 4-6, 6-4, 6-4, 6-4 victory over Carlos Alcaraz on July 13, 2025, will see nearly half of his £3 million (approximately $4.05 million) prize money reduced due to UK tax obligations. The world No. 1’s triumph, marking his fourth Grand Slam, comes with a significant financial caveat as HM Revenue & Customs imposes a hefty tax on non-residents’ earnings from the tournament. Tax expert Sean Packard estimates an effective tax rate of 36.52%, reducing Sinner’s net earnings to at least $2.5 million, per available reports. This deduction stems from the UK’s practice of taxing prize money and endorsement earnings tied to Wimbledon, with an initial 20% withholding tax applied before additional rates up to 45% after expenses, according to international tax consultant Andreas Bosse.
Sinner, residing in Monaco—a tax haven with no additional income tax—avoids double taxation, as the UK tax is treated as a credit against any home country liabilities, per Forbes. This contrasts with Alcaraz, who faces Spain’s higher tax rates on his £1.52 million ($2.09 million) runner-up prize. The tax hit is a common burden for non-UK players, with Iga Swiatek, the women’s champion, also losing about half her $4.1 million to a 36.52% rate, plus an additional 4% in Poland, further reducing her take-home pay. Sinner jokingly acknowledged the financial sting post-match, referencing a champagne cork interruption as part of Wimbledon’s “expensive” nature, though his focus remained on the trophy.
The £53.55 million total prize pool, up 8% from 2024, reflects Wimbledon’s commitment to equal pay, but the tax burden highlights a persistent challenge for international players. Sinner’s net earnings, after coaching and travel costs, could dip below 50% of the prize, underscoring the real cost of glory on the global stage.
