CPF Retirement Sum top up limit is to FRS or ERS?

Hi anon,

The limit depends on the recipient's age.

For anyone below 55, you can top up the SA to the prevailing FRS with tax relief on the first $7K

For anyone above 55, you can top up the RA to the prevailing ERS, but any topups beyond FRS will not have any tax relief.

I believe it is cash RSTU into SA up to FRS before age 55, cash RSTU into RA up to ERS after age 55?
