CHAPTER 1: Introduction
A. The Constitution and the Income Tax

A. Tax Payers and Tax Rates

Progressive Rate System: Income-tax rates for individuals and corps have almost always been progressive—i.e., tax on a high income is a larger percentage of the income than the tax on a lower income.

i) Proportional (not used): A tax on the same percentage of all income, i.e., 20% of all income. (A-100K, B-20K, after tax A would have 80K, while B would have 16K, A still has 5X the amount of income as B)
ii) Regressive (not used): A tax on the larger percentage of lower income than of higher incomes, i.e., a tax of 20% of the first 100K, plus 10% of the amount of income over 100K.
*After the progressive rate system is implemented, as a general rule, if A’s before tax income is higher than B’s before tax income, A’s after tax income will also be higher than B’s.
*A variety of tax provisions subject various kinds of income to lighter than normal taxation, to further non-tax policies favored by legislators

B. Tax-Rate System: The tax-rate schedules of § 1 apply to the taxpayer’s taxable income. Taxable income is computed by subtracting from the taxpayer’s gross income (See § 61) any allowable deductions.
§61 Gross Income Defined—encompasses only the gross amount of wages, dividends, interest, rent, etc…received by the taxpayer undiminished by any deductions attributable to such income
HYPO: (Progressive Structure) A, single male, has $100K of taxable income.
Rate schedule—Over $53,500 but not over $115, 000…is taxed at $11,493, plus 30% of the excess over $53,500.
•$11,493 is automatic
•With 100K, A is $46,500 over $53,500. This amount is taxed at 30%
(46,500 x .30) and equals $13,950 of additional tax.
•Tax Liability of A: $25,443 ($11,493 + $13,950)
•A’s marginal tax rate is 30%
•A’s average tax rate is 25.433% (divided by 100K)

HYPO: A earns $50K a year, for ten years. B earns nothing in yrs. 1, 3, 5, 7 and 9 and 100K in yrs 2, 4, 6, 8.
Rate Schedule—0% of the first $25K a year of income plus 10% of the amount by which the taxpayer’s income exceeds $25K
•A, each year is taxed $2500. $25K for ten years
•B, is taxed nothing in 1,3,5,7,9. But in years 2,4,6,8,10 is taxed at a rate of 10% on the $75K. $7500 per year, or $37,500K total for years 2,4,6,8,10

C. Internal Revenue Service
*Major function is to see that taxes are collected
*“Letter rulings” in response to taxpayer requests for rulings on contemplated transactions are made public, but they are not meant to have precedential value.
*A ruling request must contain a complete statement of the facts relating to the transaction in question and copies of relevant documents.

D. Tax Controversies: Taxpayers are required to file returns and pay the taxes due. If there is a controversy w/ reportable income, the following procedure is implemented:
(1) Action by the IRS: Most are settled by agreement b/t the taxpayer and Revenue Agent. If not, the IRS will send a 30-day letter explaining its determination/position.
•If no action is taken w/in 30 days by the taxpayer (a written protest or payment), a deficiency notice, or 90-day letter will be sent.
•Taxpayer

II: The Concept of Income
A. Basic Tax Computations
*Taxable Income: Calculated by subtracting the taxpayer’s deductions from gross income. (If gross income is 200K, and deductions are 50K, taxable income equals 150K)
(1) Individual Taxpayers: Calculations of taxable income involves two steps
(a) Deductions (from § 62—above-the-line deductions) are subtracted from gross income, yielding a figure called adjusted gross income (AGI)
*§62 encompasses all business expenses (except most employee business
expenses), investment expenses pertaining to rents.
(b) Next, the taxpayer subtracts deductions for personal exemptions (not tied to actual outlays) and either (i) itemized deductions or (ii) standard deduction from AGI to determine taxable income. (If your itemized exceeds your standard, you deduct the itemized. If your itemized is less than the standard, you deduct the standard)
*All taxpayers will deduct their above-the-line deductions and their personal exemptions.
*Itemized deductions: deductions other than above-the-line deductions, personal exemptions and the standard deductions, i.e., charitable contributions, home mortgage interest, state and local income taxes, property taxes
*Standard deductions: Statutory Amount (usually 5K for married couple, 3K for individual)
