Hi guys. Is it a good idea to invest in SSPN/SSPN-i (not interested in the Plus) for the long run to get the maximum RM6,000 tax relief every year (e.g. put RM500 every month)? I'm not intending to use the money in SSPN-i in the short run as I already have an emergency fund to cover any emergencies.

Is there a drawback I'm not seeing?

No tax relief if you're saving for yourself: https://www.ptptn.gov.my/web/guest/simpanan/cukai
