Ozzy Osbourne’s sudden passing has shaken the world of music and left his family facing an unexpected struggle. 

The rock legend, who passed away at 76 after suffering a cardiac arrest at his home in the U.K., was remembered as one of the most powerful voices of heavy metal. 

But behind the grief, serious financial issues have now surfaced.

Reports revealed that Osbourne, despite earning more than $300 million during his career through songs, tours, television and business, still owed millions in unpaid taxes. 

Federal filings showed two liens were filed against him and Sharon Osbourne, one worth nearly $700,000 in 2023 and another exceeding $4.3 million in 2024. In total, the debt was close to $8 million.

Law experts explained that because the late music icon owned homes in both America and Britain, his estate will be taxed under both systems. 

However, U.S. estate taxes apply to amounts above $14 million, while the U.K. imposes a 40 percent inheritance tax on estates worth more than £375,000. 

This means that a large portion of Osbourne’s fortune could be lost before it is passed on.

Family lawyers also pointed out that inheritance disputes may arise, especially with Osbourne’s blended family. If older children feel excluded, the process could become long and bitter.

Even in his final weeks, Osbourne was still giving back. On July 5 he performed at Black Sabbath’s “Back to the Beginning” charity concert in Birmingham, which raised nearly $190 million for medical causes.
