DETROIT (AP) — Attorney’s for Aretha Franklin’s estate have said they have paid at least $3 million in back taxes to the IRS since her death in August.

The IRS has filed a claim in probate court against the estate.

Earlier Thursday, TMZ reported that legal documents it obtained showed the IRS claimed the singer owes more than $6.3 million in back taxes from 2012 to 2018 and $1.5 million in penalties.

“We have a tax attorney. All of her returns have been filed,” Bennett told the AP. “We have disputes with the IRS regarding what they claim was income. We claim its double-dipping income because they don’t understand how the business works.”

He added that Franklin had a lot of expenses whenever she toured.

“She had to pay for transportation, hotel rooms, backup singers, musicians. When she did that the IRS was questioning the returns she filed,” Bennett said. “We’re going through audits. Returns were filed as timely as we could get them filed.”

Franklin died of pancreatic cancer in August in her Detroit apartment. She was 76.

At the time of her death, Franklin owned a home in Oakland County’s Bloomfield Township. The IRS filed the claim this month in Oakland County Probate Court in Pontiac.

Documents filed in an Oakland County court after Franklin’s death did not mention the value of her estate, which could run into the tens of millions.

Franklin left no will when she died. She was not married and left four sons: Clarence Franklin, Edward Franklin, Kecalf Franklin, and Ted White Jr. Clarence, Aretha’s eldest, is incapacitated and is represented by a guardian. And a niece of hers is the executor.

Franklin’s estate also has paid money to the state of Michigan and other jurisdictions “where she would have had some income,” Bennett said.

Franklin had been the target of many lawsuits by creditors during the late 1980s and 1990s.

In 2008, the singer said an attorney’s mistake caused her $700,000 mansion in Detroit to slip into foreclosure over $445 in 2005 taxes and late fees. The Detroit Free Press reported then that Franklin owed a total of $19,192 in back taxes on the property through 2007.
