Floyd Mayweahter has posted a cheque on social media to show the staggering amount of tax he paid last year.
And the boxing star is making grand plans for the Super Bowl in Las Vegas this weekend, too.
On Thursday, Mayweather revealed that he'd paid a massive $18million (£14.3million) in tax this year after taking to Instagram.
And the 46-year-old, who lives in Vegas, also showed off that he'd spent $1.1million (£870,000) paying for 34 friends to watch the Super Bowl.
In his first post, the boxing icon said: "I don’t kiss ass and I never have to beg for nothing especially not to get a Super Bowl suite.
"I don’t mind accepting invites at times, but one thing's for sure… the person that’s paying does all the saying.
"Therefore I get my own seats and suites so I can do what I want and invite who I want!
"I’m blessed to be taking 34 people to experience the first Super Bowl in Las Vegas! $1,131,000.00."
Mayweather then made it clear the money was small change for himself given what he'd paid in tax.
The 46-year-old is considered one of the best boxing stars of all time, despite sometimes courting controversy.
He famously beat the likes of Ricky Hatton and Manny Pacquiao in 2007 and 2015 respectively.
And though Mayweather retired from boxing in 2017, he's continued to return to the ring for lucrative exhibition bouts.
The American has faced Logan Paul and Conor McGregor, while there's talk he could yet continue to fight in the future.
Mayweather is believed to have an eye-watering net worth of $400m (£316m) and continues to add to his wealth via his various businesses.
Fans have reacted to Mayweather's post on social media, with one user saying: "Pennies for him."
A second stated: "How much money does he have?"
A third stated: "Bro isn't playing with anyone."
A fourth weighed in: "Lifestyle of the rich and famous. That's pretty dope."
And a fifth amusingly said: "I'm not working hard enough."

Meanwhile, Hatton recently said he'd be interested in a rematch with Mayweather a huge 17 years on from their first fight.
He recently said: “If someone turned around and said do you want an exhibition and move around with a Marcos Maidana, Miguel Cotto, Floyd [Mayweather] or Manny [Pacquiao], if something got put to me and it tickled my fancy and I thought I could benefit from it then, yes, because I don't have many exhibitions left in me, sooner or later the party ends and you've got to hang them up; boxing, fighting, exhibitions, the lot, so while we're still in the position to do it, I'd certainly be a fool not to look at opportunities.”
And Hatton also said he'd be intrigued by a potential exhibition between Mayweather and Pacquiao, too.
“I think Manny and Floyd could do an exhibition," he added.
"Their first fight was a chess match and I don't think in the rematch either would take any liberties.

"I think it would be very, very entertaining watching two of the greatest fighters ever sharing the ring and showcasing their skills one last time without seeing either of them getting hurt.
"I think people would pay to see it and I think their motivation to fight is simple case of - not being greedy for money or anything like that - but because you hold on for as long as you can, you don't want to let go of boxing because it's been such a big part of your life, it's a better drug than anything you can think of, to have that crowd roar and that adrenaline buzz that makes you feel like you're going to fall of the edge of the world as you walk towards the edge of the ring for a fight.
"I think Mayweather and Pacquiao don't want to let go of that.”
