According to filings submitted by the Internal Revenue Service (IRS) in Las Vegas in March 2026, the lien stems from unpaid federal taxes in 2018 and 2023.
Under a federal tax lien, the government maintains a legal claim against a taxpayer’s property to secure payment of a debt. If the liability remains unpaid, this measure can escalate to a levy, allowing the government to seize and sell assets such as bank accounts, real estate and personal property.
Mayweather’s legal representatives declined to comment on the filings, according to Business Insider.
This is not the first time the boxer has faced significant scrutiny from the IRS. He was previously hit with a $22.5 million tax bill in 2015 and $7.2 million in 2010.
While those prior debts were eventually settled, the nature of these filings suggests ongoing problems in the 49-year-old’s tax management.
Despite earning an estimated $1.1 billion to $1.4 billion throughout his decorated career, Mayweather’s current financial situation has come under question in American media.
Besides the tax debt, Mayweather has faced lawsuits over unpaid luxury goods, including high-end watches and jewelry, and claims from YouTuber-turned-boxer Logan Paul, who alleges Mayweather still owes him roughly $1.5 million from their 2021 exhibition match, according to Complex.
In contrast to these reports, Mayweather continues to affirm his immense wealth through new investment ventures. Last year, he claimed to have finalized a $402 million deal to purchase 62 buildings in Manhattan, totaling over 1,000 apartments. He asserted the deal would generate millions in monthly rental income, though the exact details of the transaction remain unverified.
The boxer’s recent moves further reflect his effort to generate significant cash flow. In February, Mayweather filed a $340 million lawsuit against his former television partner, Showtime, alleging the network misappropriated revenue from a 2013 broadcasting contract. Showtime has denied all allegations.
Additionally, Mayweather recently announced a return to professional boxing after nearly nine years of retirement. He is currently finalizing a high-profile rematch with Manny Pacquiao scheduled for September 2026 in Las Vegas. He has also scheduled exhibition matches in Africa and Europe against Mike Tyson and kickboxer Mike Zambidis, bouts that typically bring in tens of millions or even hundreds of millions of dollars in revenue.
However, Mayweather’s financial pressure did not just come from his income, but also from his spending and investment structure, defined by private jets, a rotation of supercars and high-end estates, which place a heavy burden on his liquid assets.
Reports indicate he may have recently offloaded several major properties, including his Beverly Hills and Miami mansions, along with his “Air Mayweather” private jet.
