The maximum amount you can voluntarily top up to your MediSave Account is the difference between your Basic Healthcare Sum (BHS) and your current MediSave balance. Once your BHS has been reached, no further voluntary top-ups can be made to your MediSave Account. If you exceed your BHS from the top-up, the full amount of your top-up will be refunded to you.

 

You can check your top-up limit with these steps.
