In a plea agreement, the music mogul has admitted running scams that defrauded investors and major banks for more than 20 years.
Mr Pearlman entered a not guilty plea last year, but is scheduled to reverse that in court in Florida on Thursday.
The charges carry a maximum of 25 years in prison and a $1m fine.
Mr Pearlman, 53, is expected to plead guilty to two charges of conspiracy, money laundering and making false statements during a bankruptcy proceeding.

According to the 47-page plea agreement, Mr Pearlman has admitted enticing investors and banks to invest millions of dollars in two companies that "existed only on paper".

Prosecutors counted at least 250 individual victims who lost $200m (������£101m), plus 10 financial institutions that lost $100m (������£50.6m).
As part of the deal, Mr Pearlman has pledged to help investigators prosecute his accomplices and agreed to help authorities recoup millions of dollars for his victims.
He has also agreed to forfeit four cars, including a 2004 Rolls Royce Phantom and two bank cheques totalling $97,000.
Mr Pearlman has been in an Orlando jail since being returned to Florida in July 2007.
He earned widespread fame in the 1990s for creating successful pop sensations.
The Backstreet Boys and 'N Sync eventually sued him, claiming he was siphoning large amounts of money from them. The cases were later settled, but the terms were not disclosed.
