Tax System Analysis

A good tax should benefit everyone.
Sufficiency is measured by whether taxes generate enough revenue for government services.
The US tax system is currently insufficient, leading to borrowing and a deficit.
Operating at a deficit isn't always negative if the country's GDP growth exceeds the debt's interest rate.
Supply-side economics suggests that efficient government operations can positively impact the economy.

Convenience can be viewed from both the taxpayer's and the government's perspectives.
From the taxpayer's perspective, the tax system's increasing complexity makes it inconvenient.
From the government's perspective, the tax system isn't convenient due to understaffing and infrastructure issues at the IRS.
Sufficiency and convenience are generally considered objective standards.

Efficiency refers to the government's use of tax policy to achieve specific goals, like encouraging marriage, homeownership, religious observation, and charitable contributions.
These goals reflect societal values and morals that the government aims to promote.
Efficiency is subjective and hard to measure because governmental policies and their connection to taxes aren't always clear.
Income tax preferences are special tax benefits for certain types of policy that the government wants to encourage, like:
- Preferred rates for certain dividends.
- Reduced rates for long-term capital gains.
- Tax-exempt interest from state and local bonds (0% tax rate).

Fairness is a subjective standard related to the ability to pay.
Horizontal Equity: Individuals with the same income should pay the same amount of taxes.
Vertical Equity: Individuals with higher incomes should pay more taxes.
Tax policies often alter both horizontal and vertical equity.
Rate Structure:
- Progressive Tax: As the base (income) increases, the rate increases. (e.g., Federal Income Tax)
- Regressive Tax: As the base increases, the rate decreases. (e.g., Social Security payroll tax)
- Proportionate Tax: The rate is the same regardless of the base. (e.g., Corporate Income Tax at a flat 21%)
Average Tax Rate: \frac{\text{Tax Liability}}{\text{Taxable Income}}
Marginal Tax Rate: The tax rate applied to the next dollar of income.
Effective Tax Rate: \frac{\text{Tax Liability}}{\text{Total Income}}
Perceptions of inequity can lead to lower tax compliance.
It’s important for the government to show fairness

Taxes need to be considered every time they come into play.
Taxes must be considered when evaluating business decisions and property sales.
Transactions involve one person dealing with another.
Many transactions occur over multiple years, requiring consideration of present value.
Present Value:
- The current value of a future cash flow.
- The concept that a dollar today is worth more than a dollar tomorrow.
- Present value is calculated using factors from Appendix A of the text.
- The rows reflect the time period.
- The columns reflect your internal rate of return or your discount rate.
Expenses can save us on taxes.

Cash flow includes taxable and nontaxable revenue, as well as deductible and nondeductible expenses.
Before-tax cash flow is affected by taxes or savings.
After-tax cash flow includes tax consequences.
Multiple-year transactions require the present value of future cash flows to determine net present value.
Maximize cash flow, not minimize taxes.

Private Marketplace:
- Both parties are private, on their own, and negotiate at arm's length.
- Terms are fair and apply to any participant.
Public Marketplace:
- One party sets the terms, and the other takes it or leaves it (e.g., buying US Treasury bonds).
- Prices are set.
- Only one party can negotiate.
Fictitious or Related Party Marketplace:
- Buyer and seller are connected and can structure terms for their benefit.
- Terms may not apply to others due to the relationship skewing the deal.
- A related party marketplace is not a reliable one.
- Not at arms length

The law presumes related parties do not act at arm's length, which cannot be disproven
The code may disallow certain tax consequences (e.g., deducting losses on sales to related parties).
Related parties are defined in the code as people with a relation to you, or companies that have common heritage.
