Annuities may be purchased through a retirement account such as an IRA. In these cases, required minimum distributions (RMD) and other requirements would be in effect. Since these accounts already provide tax deferral, a variable annuity does not provide any additional tax benefits. There may be benefits such a guaranteed lifetime withdrawal benefits that would warrant consideration of a variable annuity in a retirement account. The benefits and costs should be carefully evaluated before purchasing an annuity in a retirement account.
