The sheriff's Office says Anthony is being held on $3,000 bond on new charges, including forgery and petty theft for using a friend's checkbook.
The 22-year-old woman had already been charged with child neglect, making false statements and obstructing the investigation into her daughter's disappearance.
Police say she's a person of interest in the disappearance of her daughter, who hasn't been seen since mid-June. Anthony did not report her daughter missing until July.
A family spokesman calls Anthony's arrest a "three-ring circus." Her lawyer calls it "grandstanding" by law enforcement.
