Fixed annuities do you get back principle when die?

In a fixed deffered annuity you get principle plus all earned interest.

In an income annuity, you may or may not, it depends on the company and the product chosen. This feature has only been around for a short time. So if it is an old annuity it most likely is set to pay out for a specific length of time, therefore you would not receive the principle back upon death. But the beneficiary or estate would receive the remaining payments.
