I'm not sure I understand the concept of "tax-free inside buildup."
From what I understand, life insurance, annuities and IRAs (both Traditional IRAs & Roth IRAs) benefit from "tax-free inside buildup." This essentially means that they are invested on a tax-free basis. But isn't it true that certain contributions to these devices are non-deductible?
I'm not sure what the term is intended to convey. If an example can be provided that would also be helpful.
