A tax-free retirement account, or TFRA, is a type of cash-value life insurance plan created to help eliminate taxes on your retirement income. A tax-free retirement account or a Section 7702 plan is funded through a permanent life insurance policy with cash value, such as a Gold Silver Backed IRA. Depending on how a TFRA is structured, it can be a full life policy, a variable life policy, or a universal life insurance policy.
