What would be your recommendation for sites/banks to invest? and how to build a portfolio to maximize tax relief and security? Any thoughts on SRS accounts?

SRS gives you a tax break now but when funds are finally paid out (after retirement age) you have to pay tax based on 50% of distributions at a rate based on your income at the time.

At retirement age, you are likely to have less income (its called retirement for a reason) so you have some control over the tax payable.

It isn't a fantastic benefit (eg CPF SA cash topups are fully deductible with no backend catch) but if you can plan ahead appropriately, then it is worthwhile to investigate.

Hi! For srs, you can probably find a srs tax calculator online to determine whether at your current income levels it is worth it or not to reduce tax via srs :)
