Advisers should check if pensions are grandfathered when stopping and starting ABPs to avoid potentially devastating outcomes for some clients, an SMSF technical expert says.

The latest ATO statistics have shown SMSF members in retirement have historically been drawing down more than the minimum pension required.

The ATO has released guidance intended to help funds navigate the new TBA debit calculation for commutations of market-linked pensions, which was passed as law in June.

SMSFs with a lifetime pension in place could face conflicting legislative instruments due to the current economic climate, a technical expert has said.
