Jannik Sinner immediately loses half of massive Wimbledon prize money after win over Carlos Alcaraz

New Wimbledon men's champion Jannik Sinner will leave London a wealthier man but almost half of his earnings from the championship won't make it through border control.

Wimbledon singles champions claim prize money of £3 million, which is awarded to both the men's and women's winners.

Sinner won Sunday's men's final in four sets but won't take home anything like £3 million from his first-ever Wimbledon triumph.

Like women's champion Iga Swiatek, who defeated Amanda Anisimova in the final on Saturday, Sinner can immediately say goodbye to about half of his winnings.

The world number one lifted the famous pineapple-topped trophy in SW19 but HM Revenue & Customs banked its own windfall before he'd packed his racquets away.

According to tax expert Sean Packard via Forbes, Swiatek and Sinner's winnings will be taxed by the UK "at an effective rate of 36.52%."

While Alcaraz's previous Wimbledon winnings were taxed at Spain's much higher rate, Sinner has no such issue.

"Sinner will pay no additional income tax outside of the U.K. because Monaco is his primary residence," according to Forbes.

Alcaraz made relatively short work of the first set on Centre Court and capped it with a spectacular set point before an aggressive Sinner held his serve in a sensational final game to win the second set.

The Italian also claimed the third, capitalising on Alcaraz's problems with first serves despite a double fault of his own in the final game of the set.

A gritty fourth-set performance took Sinner to a 4-6, 6-4, 6-4, 6-4 win and a fourth Grand Slam tournament win for the 23-year-old.

Sinner has added the Wimbledon title to previous wins in the Australian Open and US Open, which he won consecutively before serving a three-month ban per an agreement with the World Anti-Doping Agency (WADA) after testing positive for a banned anabolic steroid last year.

But his performance against back-to-back champion Alcaraz at Wimbledon on Sunday was extremely impressive and leaves him just a French Open title short of what would be a phenomenal career Grand Slam.

Sinner's final victory offered a measure of revenge after Alcaraz defeated him in an epic French Open final at Roland Garros in June.
