Wow found out that SRS is actually something that people do yearly? Have you SRS-ed this year? Could you also explain what SRS is about?

SRS is basically an initiative to encourage people to save and invest for their retirement. They do this by giving tax relief for the amount that you put into SRS.

If you are looking for tax relief, it probably makes sense to max out all the other tax relief offerings before SRS. Commonly, CPF RSTU gives you up to 7k tax relief if you top up your own CPF SA with cash. (Up to FRS.) And up to an additional 7k tax relief if you top up for your spouse/siblings/parents (subject to income restrictions).

In addition, tax relief probably makes more sense when you are in a higher tax bracket. So if one is not in the higher tax brackets, there may not be a need to sacrifice liquidity just to get some tax relief.
