The city of Chicago plans to sue Jussie Smollett to recoup the cost of investigating an alleged assault on him in January.
The Empire actor told police he had been the victim of a racist and homophobic attack in the city on January 29.
However, prosecutors say the attack was staged in a bid to boost his career and ordered Smollett to pay $130,106.15 to cover the cost of the investigation within seven days.
The deadline for payment has now passed and the city of Chicago's law department said in a statement that it would be suing Smollett in Cook County civil court "in the near future" and will "pursue the full measure of damages allowed".
The statement said: "Mr Smollett has refused to reimburse the City Of Chicago for the cost of police overtime spent investigating his false police report on January 29, 2019.
"The Law Department is now drafting a civil complaint that will be filed in the Circuit Court Of Cook County. Once it is filed, the Law Department will send a courtesy copy of the complaint to Mr Smollett's LA-based legal team."
Last month, the criminal charges against Smollett were dropped but prosecutors say they still believe the Empire star faked the attack.
The Mayor of Chicago, Rahm Emanuel, expressed his anger, saying a "whitewash of justice" had occurred.
Smollett has always maintained he told the truth since reporting the alleged attack to police.
