It is not mandatory for you to top up your Retirement Account (RA) if you are unable to
set aside your Full Retirement Sum (FRS). You can still receive monthly payouts anytime from your payout eligibility age, and the payout amount will be based on your RA savings.
If you receive contributions, government grants or other refunds in your CPF accounts after 55, they will be transferred to your RA up to your FRS (or
Basic Retirement Sum if you own a property) on your next withdrawal.
