Description: Public policy makers acknowledge that there exist significant tax incentives for the use of Registered/Qualified Pension Plans and RRSP's/lRA's. This is the abstract of a paper that first analyzes these tax advantages as to the component source, i.e., how much of the advantage can be attributed to the tax deductibility of contributions and how much is because of the non-taxation of the investment income until taken. The paper then attempts to determine and illustrate whether or not these elements of tax assistance should be viewed as tax deferral or tax waiver. The analysis shows that any tax advantages associated with the deductibility of contributions is only tax deferral. However, the paper proves that there is a permanent loss to the taxpayers associated with the non-taxation of earned investment income until taken which should be viewed as a tax subsidy or tax waiver. The paper ends with a short discussion of the public policy issues raised by these findings. From Actuarial Research Clearing House 1994, Vol. 1.
