Reuters, citing Chinese state media, said the actress' fines totaled 479 million yuan ($69.74 million), while her outstanding back taxes were calculated at 255 million yuan ($37 million). Reports suggested she was involved in an investigation into tax evasion in the film industry, with speculation she had been detained. She had instead paid taxes on a contract for only 10 million yuan, Xinhua said.
"I sincerely apologize to everyone", she said in a statement she reportedly posted to an official social media account.
The actress will not face criminal penalties if she pays the fines and back taxes, Xinhua reported.
But she disappeared from the public eye and her once active social media presence went silent in May after allegations emerged that she had evaded taxes on a lucrative movie shoot, charges her studio called "slander". I have failed the support of my country, the trust of society, and the love of my devoted fans!
On Wednesday, the South China Morning Post said Fan was released two weeks ago from "residential surveillance" at a "holiday resort" in Jiangsu used to investigate officials.
Her wording is obviously taken from the 1943 red song and slogan "Without the Communist Party, there Would Be No New China". "I have failed my nurturing country". However, the report stated that she was again arrested in early August and has been in prison since then, with industry insiders saying this is already the equivalent to a "death sentence" in the entertainment business from which she "really can not come back".
There was no immediate comment from Fan or a representative for the actor. She would use the contract with a much smaller sum to report to the government, while not reporting a much larger one.
Last month, Beijing Normal University released a study which attempted to assign a "social responsibility rating" for each Chinese film and television star.
The 36-year-old actress, model and producer had been a ubiquitous household name in China for years and tasted Hollywood success with a role in the 2014 blockbuster "X-Men: Days of Future Past". She has turned heads at the Cannes Film Festival for years, to where fashion brands like Armani, Versace, Dior and Louis Vuitton want to dress her. Esquire's China edition named her the "Most Beautiful Woman In The Year" in 2012.
