In 2001, the Department of Justice seized his house in La Salle Road and later auctioned it for HK$4.35 million after 10 years of civil proceedings.

[citation needed] Perry Lam, a cinema critic from Muse, wrote that Tsang 'brings directness, straightness and a lack of nonsense to whatever role he plays, and occasionally demonstrates an uncanny ability to enter the egoless states of which only the greatest of character actors like Robert Duvall are capable.

Despite his high-pitched voice, he sings his parodies and theme songs to variety shows in a low-range tenor or high-range baritone of 2 octaves.

[12] In January 2021, Tsang was appointed TVB's deputy general manager (Non-Drama, Music Production & Programme) and special advisor to the executive committee and will be responsible for the variety show and infotainment program segment.

[16] On 21 April 2013, the Hong Kong 3 Weekly Magazine reported that Tsang's current wife was named Sung Lai Wah (宋麗華) and they had lived apart for 20 years.

[18] In December 2013, Next Magazine published an anonymously produced interview with actress Yammie Lam where she said that she had been raped by two Hong Kong entertainment industry "big brothers" 20 years ago.

In the new 2018 clip, the interviewer now has a natural female voice, and the formerly censored portions implicate Alan Tang (deceased in 2011) and Eric Tsang as the two alleged rapists of Lam.

[21] Two days after the release of the January 2018 video, the sexual offense claim against Eric Tsang was corroborated by Grace Han, a talent agent who formerly headed the Ford Models agency in Asia.

Han further alleged that Eric Tsang had sexually assaulted more than one woman, and claims to know of a specific incident in which a group of male Hong Kong celebrities, led by Tsang, allegedly drugged seven female models in a Hong Kong karaoke bar and raped six of them, while one girl escaped after she noticed the drugging.

[25] A week after the allegations surfaced, Tsang filed a defamation lawsuit against Grace Han in the Hong Kong High Court, arranged for a press event, and announced that "punishment" is needed.
