$30,000 of income and a 30% tax rate on all earnings over US $30,000 has a(n):

  1. Marginal tax rate of 15%.
  2. Marginal tax rate of 21%.
  3. Average tax rate of 21%.
  4. Average tax rate of 22.5%.

A tax is regressive if:

  1. Individuals with higher incomes pay a higher percentage of their income in tax.
  2. The burden for payment falls disproportionately on lower-income persons.
  3. Individuals pay a constant percentage in taxes, regardless of income level.
  4. Individuals with lower incomes pay a lower percentage of their income in tax.

Answer(s): B

Explanation:

With a regressive tax, the percentage paid in taxes decreases as income increases. For example, excise taxes and payroll taxes are both regressive taxes. An excise to is regressive because its burden falls disproportionally on lower-income persons. As personal income increases, percentage of income paid declines because an excise tax is a flat amount per quantity of the good or service purchased.



General sales taxes tend to be regressive with respect to income because:

  1. A larger portion of a lower income person's income is subject to the tax.
  2. A smaller portion of a lower income person's income is subject to the tax.
  3. The tax rate is higher for person with lower income.
  4. The tax claims an increasing amount of income as income rises.

Answer(s): A

Explanation:

A sales tax is regressive with respect to income even though the rate is the same regardless of the buyer's income. The reason is that a greater percentage of a low-income individual's income is exposed to the tax. A higher-income individual should be able to save more and therefore shield a greater percentage of his/her income from the tax.



Under a value-added taxing system:

  1. Businesses must pay a tax only if they make a profit
  2. The consumer ultimately bears the incidence of the tax through higher prices.
  3. Consumer savings are discouraged.
  4. The amount of value added is the difference between an entity's sales and its cost of goods sold.

Answer(s): B

Explanation:

A value-added tax is based on consumption. The tax is levied on the value added to goods by each business unit in the production and distribution chain. It is the consumer who ultimately bears the incidence of the tax because businesses subject to the tax will raise prices to offset the operating cost of the tax.

  1. Option A
  2. Option B
  3. Option C
  4. Option D

Accordingly the taxpayer will experience an increase in both nominal taxes payable and in real taxes payable.
