Sigel was supposed to be sentenced Thursday, but defense attorneys Fortunato Perri, Jr. and Mark Cedrone notified U.S. District Judge Jan DuBois on Wednesday that their client had not provided the financial information a probation officer requested or permitted a home visit by the officer.
Perri said Glickman was enlisted to help prepare Sigel's financial statements and supporting documents.
DuBois rescheduled sentencing for July 12 and ordered the financial information be provided to probation and home visit be permitted no later than April 26.
Sigel could face up to three years in prison.
Assistant U.S. Attorney Paul Gray said in court papers that Sigel's lack of cooperation showed the rapper's "continuing disrespect" for the legal process.
But Perri had a more benign explanation. He said Sigel had been focused on business endeavors, in part, so he would have an opportunity to provide restitution to the government.
The defense and the feds have not yet agreed on the tax loss or restitution Sigel might owe.
DuBois ordered the parties to report back to him by June 15 if they have reached an agreement on tax loss and restitution.
If no agreement is reached, a hearing may be needed to determine the appropriate loss and restitution, the judge said.
