Carlos Alcaraz faces losing almost a third of his French Open prize money after beating Jannik Sinner in final

French Open champion Carlos Alcaraz could lose up to a third of his prize money after his fifth Grand Slam triumph.

Alcaraz, 22, beat world number one Jannik Sinner in a final which lasted nearly five and a half hours at Roland-Garros on June 8.

The pair will both be paid handsomely for their efforts, with the Independent reporting that €56.4m (£47.3m) in prize money was up for grabs throughout the tournament, with players winning more depending on how they progress in the event.

The winner, in this case Alcaraz, will reportedly pocket €2.55m (£2.13m), while the runner-up Sinner, 23, will receive €1.28m (£1.07m).

However, both will lose a significant amount due to tax.

According to My Tennis HQ, “The amount of tax money a tennis player will pay on prize money will depend exclusively on the location where the money was earned, made, or received. After a player competes in Wimbledon, for instance, he or she is taxed according to U.K. taxation laws, regardless of where that player is from. If that same player competes in the French Open, he or she will be taxed according to French taxation laws, and so on. After the players pay taxes to the local government where the prize money was earned, they do not have to pay income tax on it again when they return back home”.

So, with the French Open taking place in France, the country's taxation laws will apply.

It is estimated that around 30 per cent of Alcaraz’s earnings will be paid in tax, equal to around £639,000, but it is difficult to give a confirmed amount.

So what will the Spaniard do with his money?

Well, ahead of the tournament, the 22-year-old revealed that he likes to treat himself after big Grand Slam victories.

“Maybe not after every big win, but for example, at the Grand Slams, if I reach the semi-finals, I like to buy myself a new pair of sneakers," Alcaraz said when speaking on the Tennis Channel.

"If I feel like I had a good season, at the end of the year I'll buy myself a nice watch."
