As long as you are not an ex-cadre PAP, you would not have to worry. Look at Tang. The tax dept raided him. The house in his wife's name was seized. His name did not appear on the deed. And what exactly did Tang do. They said he was a chinese chauvinist but his good friend when he took flight to JB was a Malay. And he was trained in the Indian arts.
I don't think that PAP takes anyone seriously now. If so, that person better worry. The last few times PAP takes anyone seriously, they all become prisoners or fugitives.
