It’s reasonable to describe CPF LIFE as compulsory, even though the official term is “mandatory.”
The reason is simple: for most CPF members who meet the criteria (age, RA balance, etc), there’s no real opt-out in practice.
Yes, you could technically opt out by renouncing citizenship or by having a private annuity approved by CPFB. But those are either extreme (giving up citizenship) or extremely rare (private annuity exemption).
So while “mandatory” might be legally correct, it’s accurate - and fair - for people to deem it compulsory, since they can’t realistically choose otherwise.
