Key Takeaways:
Britain's tax regime is driving the world's best tennis players away from the country's grass-court season, with only one top-10 men's player competing at last week's Queen's Club tournament versus six at a parallel event in Germany.
The grass-court season occupies just a few weeks in June after the French Open at Roland Garros and culminates at Wimbledon's Centre Court. Yet even that brief window is proving too costly for many players under the UK's tax treatment of athlete income.
"Players are making a simple economic calculation — the tax bill from playing in Britain can exceed the prize money if they lose early," said James Atkinson, a sports tax partner at accounting firm Moore Kingston Smith. "The UK is pricing itself out of the warm-up circuit."
Britain taxes tournament prize money at standard income tax rates. A player exiting Wimbledon in the first round earns £80,000, with a portion taxed at the 40 percent marginal rate. Reaching the third round brings £158,000, with a tranche subject to the 45 percent top rate.
The more punitive provision targets endorsement income. The UK calculates tax on global sponsorship deals based on the proportion of days a player spends in the country. If a player competes on 100 days worldwide and five of those are in Britain, the UK taxes 5 percent of their total endorsement earnings. For a top-10 player with multi-million-dollar sponsorship deals, a first-round exit can leave them with a net loss after accounting for the tax liability.
The Numbers Tell the Story
Last week's men's tournament at London's Queen's Club, the primary Wimbledon warm-up, drew only Australian Alex de Minaur — ranked sixth in the world — alongside 31 lower-ranked competitors. Across the English Channel in Halle, Germany, six top-10 players including Americans Ben Shelton and Taylor Fritz competed in a tournament of similar stature.
The women's draw tells the same story. Three of the top 10 players entered the Queen's Club tune-up, compared with six playing in Berlin the same week. British fans saw world number two Elena Rybakina and Canadian Victoria Mboko but missed world number one Aryna Sabalenka and American star Coco Gauff.
The pattern extends beyond tennis. The UK's tax treatment of globally mobile athletes has drawn criticism from sports bodies for years, with footballers and Formula 1 drivers similarly affected. The current top rate of 45 percent on income above £125,140 is among the highest in Europe, and the endorsement income rule — unique in its global reach — creates a disincentive that no other major tennis nation imposes.
What's at Stake
The economic impact extends beyond ticket sales. The grass-court season generates significant revenue for London hotels, restaurants, and transport providers. The All England Club reported that Wimbledon contributed £380 million to the UK economy in 2024. A diminished warm-up circuit threatens that ecosystem, as fewer top players means lower broadcast rights values and reduced sponsorship interest for the lead-in tournaments.
With no change to the tax rules signaled in the current parliamentary session, the exodus of talent is likely to continue. The next opportunity for reform comes with the autumn budget statement, though the Treasury has given no indication it plans to alter the treatment of non-resident athlete income.
