Each of the following tax proposals has income as the tax base. In each case,
calculate the marginal tax rate for each level of income. Then calculate the
percentage of income paid in taxes for an individual with a pre-tax income of
\(\$ 5,000\) and for an individual with a pre-tax income of \(\$ 40,000 .\)
Classify the tax as being proportional, progressive, or regressive. (Hint: You
can calculate the marginal tax rate as the percentage of an additional \(\$ 1\)
in income that is taxed away.)a. All income is taxed at \(20 \%\).
b. All income up to \(\$ 10,000\) is tax-free. All income above \(\$ 10,000\) is
taxed at a constant rate of \(20 \%\).
c. All income between \(\$ 0\) and \(\$ 10,000\) is taxed at \(10 \%\). All income
between \(\$ 10,000\) and \(\$ 20,000\) is taxed at \(20 \%\). All income higher
than \(\$ 20,000\) is taxed at \(30 \%\).
d. Each individual who earns more than \(\$ 10,000\) pays a lump-sum tax of $\$
10,000\(. If the individual's income is less than \)\$ 10,000$, that individual
pays in taxes exactly what his or her income is.
e. Of the four tax policies, which is likely to cause the worst incentive
problems? Explain.
