An Annuity in a Tax-Deferred Retirement Account?

                         

Annuities provide tax deferrals as do IRAs and 401 (k)s.

                       

So never invest in an annuity inside a tax- advantaged account such as an IRA or 401 (k), as you would get no added tax benefits. (See the Earl J. Weinreb NewsHole® comments and @BusinessNewshole at Twitter.)
