Beloved rock legend Ozzy Osbourne left his widow, Sharon, with a tragic legacy — an ocean of debt.

Insiders say Sharon and Ozzy’s move back to England in March wasn’t just out of nostalgia or homesickness — they were being hounded by creditors, including the U.S. Internal Revenue Service.

The self-proclaimed Prince of Darkness and his wife of 43 years were reportedly hit with two tax liens by the feds — one for $689,107 in 2023 and another for $4,362,410 in 2024.

“Ozzy was in serious debt towards the end when he was dying and it’s clear he was determined to work hard so he could get his family as much money as possible, which makes it so tragic,” says the insider.

“A lot of people worry he pushed himself too far doing the last show — he could barely walk or stand — but he had his reasons, especially with the debts they racked up.”

On July 5, a heroic Ozzy, his body ravaged by Parkinson’s disease, performed his final concert in his hometown of Birmingham, England, even though he had to perform sitting down.

As readers know, the “Crazy Train” singer died three weeks later on July 22 at age 76 at his Buckinghamshire mansion following a two-decade battle with Parkinson’s. He suffered from other health problems as well, including spinal issues that were the result of an ATV accident on his sprawling English country estate, followed by subsequent falls.

“Now, Sharon, who’s already grieving that he went so suddenly, must pick up the pieces and figure out what they have and settle accounts,” says the source. “The feds and their other creditors will be coming after the estate, so she is bracing herself.”

The insider says it’s ironic that The Osbournes star died with so many debts because he managed to build an impressive financial portfolio.

“Ozzy always prided himself on how well they did as a family,” the insider says. “But at the same time, even with his royalties, there wasn’t enough money coming in. It’s another headache for Sharon to deal with, which will add to her already overwhelming woes. It’s a terrible situation for anyone to be in, especially one who’s had so many health issues of her own.”
