MediSave contributions up to date before renewal
The 3-year renewal needs no outstanding MediSave, or an instalment plan with at least 24 consecutive months of contributions.
Renewal opens 60 days before expiry
The registration may be cancelled 60 days after it expires, and trading after expiry is an offence.
