Why use cash to max out MA now when the amount will be revised again next year and the year following next, etc? Just for tax relief?

Some people sees it as a bit of a high yield medical emergency fund for themselves and their family, while making tax relief.

I am not particularly sold with either MA or SA account because the interest rates can be revised down, and also it is highliy illquid. The benefit of tax relief is also more prominent when you contribute at a later age, where you are closer to CPF withdrawal for CPF SA.

I have wrote a fun article here related to topping up your SA later to get more out of the tax reliefs - https://endowus.com/insights/cpf-sa-mcq-choices/

I rather use SRS and invest SRS in equities to get a higher return.

In addition to tax relief, you get a guaranteed yield of 4% per annum. After reaching the maximum limit, the excess flows over to your Special Account. Accordingly, this helps to grow your retirement fund in due time.
