It’d likely be a smart move if her husband (your uncle) fixed that, at least for bonus interest reasons.
Unfortunately CPF LIFE isn’t a joint/survivor annuity program. It’s strictly individual, with a non-guaranteed bequest feature. Consequently, if one spouse lives a relatively long time and the other lives longer, the second spouse is in a tough spot if he/she doesn’t have his/her own CPF LIFE income stream. This scenario is fairly likely. To combat that risk, it’s preferable if both spouses/partners have some “reasonable” (or “less unreasonable”) CPF LIFE income. The government/CPF encourage some degree of “balancing” across a household with bonus interest. Bonus interest applies to the first $60,000 of CPF balances (with up to $20,000 of that from OA). So if spouse #1 is over $60,000 but spouse #2 is under, there’s some lost interest opportunity there.
Funds that are more balanced across spouses/partners aren’t “lost” if some other scenario occurs. For example, if your aunt were to pass away far too soon (hopefully not!), those transferred funds (with interest, including bonus interest) would be paid out to her nominated heir — her husband/your uncle, presumably. Those funds could then be plowed back into CPF for a higher CPF LIFE payout. And vice versa.
Make sense? It’s something to look at and consider, at least.
Is either your aunt or uncle paying any income tax currently (i.e. earning taxable income)?
