Jannik Sinner triumphed over his rival Carlos Alcarez to win the men's title at Wimbledon on Sunday, securing a $4 million prize one day after Iga Swiatek took home the women's title for the same amount—though tax analysts told Forbes their winnings will be cut nearly in half after paying required taxes.

The U.K. taxes prize funds from Wimbledon and earnings from endorsements on equipment used in the tournament, and they also face an initial withholding tax of 20% before paying a tax up to 45% after related expenses are deducted, according to Andreas Bosse, an international tax legal consultant based in Monaco.
Wimbledon's £3 million grand prize (about $4.05 million), awarded to both the women's and men's champions, would likely be taxed at an effective rate of 36.52%, Sean Packard, OFS Wealth's tax director, told Forbes, lowering the winnings down to at least $2.5 million.
Swiatek will likely also pay an additional 4% tax in Poland, reducing her championship winnings by an additional $162,000.
Sinner, originally from Italy, will pay no additional taxes because his primary residence is in the income tax-free microstate of Monaco.
A $2 million prize awarded to the runners-up would be reduced by more than $700,000 to $1.2 million if taxed at the 36.52% rate.
The U.S. requires additional tax payments, including self-employment levies or an additional Medicare surtax, Packard said, which could lower American Amanda Anisimova's prize as the womens' runner-up.
Sinner defeated Alcaraz 4-6, 6-4, 6-4, 6-4 in just three hours and four minutes Sunday, powering past his rival only five weeks after the Spanish tennis phenomenon triumphed at the French Open following a brutal five hour and 29 minute match. Sunday's win is Sinner's first championship at Wimbledon, but his fourth Grand Slam title overall. Swiatek beat Anisimova in just 57 minutes during Saturday's match, winning 6-0 and 6-0 to secure her first Wimbledon title. The match marked the first time in the Open Era of tennis matches—since 1911—that a woman won a singles title at Wimbledon without missing a single game, and is the first time since 1968 that it's happened at any Grand Slam match. What Taxes Could Jannik Sinner Pay?
Sinner will pay no additional income tax outside of the U.K. because Monaco is his primary residence, Bosse said. Other top-ranked tennis players like Serbia's Novak Djokovic, whom Sinner defeated in Wimbledon's semifinals, as well as Russia's Daniil Medvedev, Denmark's Holger Rune and Greece's Stefanos Tsitsipas also reside in Monaco, in addition to Formula 1 drivers Max Verstappen, Lando Norris and Charles Leclerc.
$72.2 million. That's the combined prize-money pool for Wimbledon, a 7% increase over the previous year, according to the tournament. Forbes Valuation
