Can withdraw but only after 3 years and must leave balance 1k.

Yes....many had said that before.
I think most would just do the "net" deposit every year to claim tax every year.....until cannot have "net deposit" for that year, then they skip 1 year no claim tax relief. Then start again the next year

See revise post above for example.
Btw, the net deposit are excludes the dividend and incentives from govt...

Yes that is correct.
Must hv net contribution for that calender year only can claim tax relief for that calender year.
Ex:
If you withdraw 10k in Feb 24, by end of Dec 24 you hv to deposit in 10k + 8k to qualify for 8k tax relief claim in Arp 25 during submission of your ITR

No, just 0 as you can't claim any for that year.

Depends on platform. Most takes a day or so depending on cut off time but I found lShopee took almost 3-5 days.

a) Online is limited to RM1K per withdrawal per day. You'll need to wait until the money is in your bank account before you can make another withdrawal.
b) Alternatively, you can withdraw at the counter for whatever amount you want & wait a few days for the money to be in your bank account.
c) You can also link your Bank Islam account to your SSPN account. This way you can make instant transfer but limited to RM50K per day.

4. RM20.
