“Participants who withdraw plan funds to cover non-retirement expenses,” notes the Pension Rights Center, “no matter how justified, are shortchanging their future. Every dollar withdrawn will no longer be in the account where it can grow tax deferred. That lost principle, combined with the loss of potential interest and investment gains over what could be years or decades, won’t be there for them when they need it in retirement. Some who withdraw assets could see their account balances reduced by thousands of dollars, tens of thousands or even more.”
