The 49-year-old, who claimed to be at the Bataclan concert hall where Islamic State attackers killed 90 people, had already been found guilty of fraud on three different occasions.
Before her arrest in February she had also been holding a paid job at a charity for victims of the gun and bomb attacks in which jihadists murdered a total of 130 people.
In her claim to police in February 2016 the woman told of "bullets whistling past her ears" at the Bataclan, but investigators found she had faked a receipt for the concert ticket and other documents to build up her claim for compensation.
On top of the 25,000 euros she claimed from the state's FGTI compensation fund for terror victims, she received more than 13,000 euros from the French health service.
She is not the first person to be caught impersonating a victim of the carnage at the national stadium and Paris nightspots on November 13, 2015, France's worst attacks since World War II.
Two people have been found guilty of fraud and another 11 of attempting to swindle the FGTI out of compensation, according to the fund.
In December Cedric Rey, an ambulance driver, was sentenced to six months in jail for pretending to have been at the Bataclan when he was not even in Paris at the time of the attack.
He had described in vivid detail to the media how he escaped death when a pregnant woman "took the bullets meant for me" -- only for the story to be exposed as a lie.
