Question: Suppose taxpayers were given a new option under the tax law for retirement funding. The new option requires that they forego a current tax deduction for pension plan ­contributions. Any contribution would accumulate in the pension fund free of tax, and distributionsfrom the plan to beneficiaries would also be tax free.

The usual rules provide for current tax deductibility of pension plan contributions and full taxation of pension plan distributions at ordinary tax rates. The tax rates at which ­contributions reduce taxes and the tax rates at which distributions increase taxes may differ because they occur at different points in time

a. Who would prefer the new option?

b. What would likely happen to taxes collected by the government in the short run? In the long run?

c. What would likely happen to the aggregate amount ofsavings undertaken through ­pension accounts?

d. How would the new option compare to one in which pension plan contributions give rise to current tax deductions and pension plan distributions are taxed at the same rate at which deductions were taken?

e. How would the new option compare to a plan with the following?

• Pension plan contributions give rise to current tax deductions.

• Pension plan distributions are taxed at the ordinary tax rates that apply at the time the distributions are made.

• Distributions are taxed at a rate above (below) the rate at which contributions are deductible and taxpayers receive a tax credit or pay additional tax equal to the difference in tax rates multiplied by the pension plan contributions.
