1. Principles of Sound Tax Policy
Brunori Chapter 2 Mikesell Chapter 8

2. Four principles of Adam Smith
The subjects of every state ought to contribute towards the support of government, as nearly as possible, in proportion to their respective abilities; that is, in proportion to the revenue which they respectively enjoy under the protection of the state.
The tax that each individual is bound to pay ought to be certain and not arbitrary.
Every tax ought to be levied at the time, or in the manner, in which it is most likely to be convenient for the contributor to pay.
Every tax ought to be so contrived as both to take out and keep out of the pockets of the people as little as possible, over and above what it brings into the public treasury of the state.

3. Five Broad Principles of Taxation
Raising adequate revenue
Neutrality
Fairness
Horizontal equity
Vertical equity
Ease of administration and compliance
Accountability and Transparency

4. Adequate Revenue
The primary purpose of any tax system is to raise revenue to cover the costs of public expenditures. Balanced budget laws largely prevent states from deficit spending. Thus, the tax system must raise the requisite revenue to pay for those services the public demands.

5. complicating factors for revenue adequacy
Anti-tax movement
Shrinking tax base

6. Neutrality
Most economists and political theorists agree that taxes should have as little effect on market decisions as possible. Neither businesses nor individuals should be forced (or encouraged) to take action solely because of tax consequences, either positive or negative.
Policymakers widely agree the tax neutrality is best attained by a system with a broad base (i.e., one with few exemptions, deductions, and credits) and low rates. Tax systems built on a foundation of broad bases and low rates will minimize the opportunity and incentive to make economic decisions based on tax savings.

7. examples of tax neutrality
High marginal tax rates for high income individuals
Marriage tax
Sin taxes

8. Horizontal Equity
The principle that similar individuals who make different economic choices should be treated similarly by the tax system

9. Vertical Equity
The principle that groups with more resources should pay higher taxes than groups with fewer resources.

10. Marginal and Average Tax Rates
Marginal tax rate: the percentage that is paid in taxes of the next dollar earned
Average tax rate: the percentage of total income that is paid in taxes

11. Vertical Equity Classifications
Regressive: Average decreases as income increases
Proportional: Average stays constant no matter what the income level
Progressive: Average increases as income increases

16. Ease of Administration and Compliance
The administrative requirements of sound tax policy entail minimizing the costs of compliance for taxpayers and of collection for the government.
The more complicated the tax system grows, the greater the costs of tax payer compliance.
The government faces many of the same problems as individuals when navigating a complicated revenue system.
Ultimately, the complications (which are usually the result of a desire to ease regressivity or to provide incentives) require significantly more resources and thus raise the costs of enforcement and collection.

17. Accountability and Transparency
Achieving accountability requires states to play several roles.
The government must ensure that those charged with the administration and enforcement of the tax laws are performing their duties efficiently and fairly.
The government must enforce the laws.
Open, transparent tax policy has proved more difficult for states to achieve.
Accountability requires states to review existing laws and determine whether they are serving the needs of the citizens.
