You can invest unprotected IRAs, SEP-IRAs or deferred compensation plan funds into a domestic single-member limited liability company (LLC). This gives your retirement funds ‘charging order protection.’ However, your plan custodian must agree to this. However, the IRA transfer can be recoverable from the LLC by a present creditor as a fraudulent transfer so you shouldn’t rely on this strategy if you have an existing creditor. However, a single-member domestic LLC can somewhat protect your retirement funds against future creditors.
