Question: Are contributions and rollovers allowed under TTR rules? I have noticed in the ING Living Super this isn't allowed.
Answer (By Paul Rickard): A Transition to Retirement (TTR) pension cannot be commuted, which means you cannot convert to a lump sum. You can't withdraw more than 10% of the account balance in any year, and you cannot add to it (by contribution or rollover).
So, essentially what ING told you is correct.
