I will turn a blind eye to the implied sarcasm here and treat it that you are ignorant. I dont mind sharing info with people who are genuinely not fully aware, but I dont normally tolerate people who know little but act like they know everything.

The SA cap is currently at $161K (as of Jul 2015).

The thing is about SA is that even when a person reaches this limit, CPF Board will still allocate part of your monthly CPF contributions to the SA. And they also retain the interest earned in the SA every year in the SA! So if you have topped up your SA like I did years ago, your SA amount will always exceed the new annual limit. And as the years go by, because of the compounding interest, the margin grows larger and larger.

On the other hand, they dont do this for the MA. Once the MA reaches the contribution limit, they stop taking your money.
