Tax Basics Tax Base

The item or activity that is to be taxed  A general tax is one that taxes all of the components of the

economic base, with no exclusions, exemptions, or deductions from the tax base.

A selective tax is one that taxes only certain portions of the tax base, or it might allow exemptions and deductions from the general tax base.

Tax Rate Structure The relationship between the amount that is

to be paid in tax and the tax base for a given accounting period

Descriptors of the Tax Rate Structure A Progressive Tax has a structure where the

marginal tax rate is increasing and greater than the average tax rate.

A Proportional Tax has a structure where the marginal tax rate is constant and equal to the average tax rate. (Sometimes called a Flat Tax)

A Regressive Tax has a structure where the marginal tax rate is decreasing and less than the average tax rate.

How Should the Burden of Government

Be Financed? Benefit Principle

Those who benefit the most from a particular program should pay the most for that program (Lindahl Tax principle at work).

Ability-to-Pay Principle Those who have the greatest ability to

pay should be required to pay the most.

13

Horizontal and Vertical Equity Horizontal equity is achieved when individuals of the

same economic capacity (measured, for example, by income) pay the same amount of taxes per year (or over their lifetimes).

Vertical equity is accomplished when individuals of differing economic ability pay annual tax bills that differ according to some collectively chosen notion of fairness.

Both concepts are subjective. “Economic capacity” is difficult to measure and

administer. “Ability to pay” requires value judgments on the

proper income distribution.

Tax Compliance, Avoidance and Evasion

Tax Evasion is the term for illegal ways to avoid paying taxes. It is typically the result of not declaring income or overstating otherwise legal deductions. 

Tax Avoidance is the term for legal ways to avoid paying taxes, typically the result of avoiding activities that are taxed, delaying the time at which taxes are owed, or taking an action designed to lower a tax burden.

More alternatives to Taxation Donations

Money (but more usually time) is voluntarily given to government. Military service or work in the Peace Corps can be considered a donation when the compensation is less than the market value of the time. 

User Charges Users of a government service can expect to pay for

that service.

Earmarked Taxes Taxes can be implemented to fund specific public

goods.

State Lotteries 38 states run or participate in lotteries.

State Lotteries account for more than 3% of state revenues.

People of varying incomes spend approximately the same amount on lotteries, which suggests that the lottery system is a regressive means of creating government revenue.

Lotteries pay out a smaller portion of revenue to winners than other forms of gaming (horse racing, casinos, etc.).
