Not sure if that’s factually correct.
by investing funds from SA, it doesn’t create more room for tax relief too up per the formula.
Tax relief is computed separately for RA from age 55, without reference to SA. However, in SA "shielding" scenarios your new RA is typically funded to the Full Retirement Sum on your 55th birthday. Once your RA hits the FRS there's no more tax relief available there.
Tax relief (for self) associated with RA, SA, and MA within a calendar year all counts toward the single combined $8,000 limit. But the FRS limit is computed separately for RA, so you get a "fresh start" in that sense.
You can get very fancy and also "shield" OA, then pump at least $8,000 of cash into RA (including some with tax relief). And right now you might be doing that by default anyway (example: 6 month T-bills in your CPF Investment Account).
also VC3A even if don’t shield also works the same way
VC3As aren't eligible for tax relief unless self-employed.
One thing he didn't mention is that even if you're a high income earner who routinely hits the CPF Annual Limit you will (per current compulsory contribution rates) have some room below the CPF Annual Limit starting in your 55th birthday year as long as your 55th birthday isn't in December. You can compute what this minimum amount is then make a VC3A in late January of your 55th birthday year. (And you can repeat this every January thereafter if you wish until the CPF Board equalizes the compulsory contribution rates for age 55+.) By December you may have a better idea if there's still any room below the CPF Annual Limit, and there might be room for another VC3A.
point 1 is wrong. you cannot pump money from oa to sa after 55 anymore. even if you vc, only a small amount end up in sa, most will go to oa
I don't think you're refuting anything in the video itself.
point 2. need to consider the interest lost in the ra. withdrawing from your oa instead of letting it go to the ra will lose you quite a bit of 4% interest. of course, under the high rate environment now. it is a good idea to do that coz the amount withdrawn can easily earn more than 4% outside,
I think you're saying that it's worth considering a OA to RA transfer while your SA is shielded. Yes, but (even better) if you have a younger spouse who can transfer his/her OA dollars to your RA, do that. Then pay your spouse back (even from your OA while your SA is shielded) if you'd like to do it that way. Releasing your younger spouse's OA dollars is surely better since he/she has months or years to go until age 55 and cannot withdraw OA dollars as unrestricted cash.
To do this you might need to "shield" OA as well as SA just before your 55th birthday, but see above (the T-bill comment).
