Income tax basics

While U.S. income tax law is very complex, the underlying idea is relatively easy to understand. Simplifying greatly, gross income

  lower the tax owed on a dollar-for-dollar basis. This means tax credits are more valuable than deductions, because deductions are applied before the tax rate, while credits are applied after. For instance, with a 35% tax rate, a deduction of $100 would save only $35 of taxes, while a $100 credit would save $100 worth of taxes.

Types of income

For tax purposes, income can be divided in a variety of ways. The first division is between ordinary income
Ordinary income

Under the United States Internal Revenue Code, the type of income is defined by its character. Ordinary income is usually characterized as income other than capital gain....
 and capital gain
Capital gain

A capital gain is a profit that results from investments into a capital asset, such as stocks, bonds or real estate, which exceeds the purchase price....
s. Ordinary income includes compensation for personal services such as wages and salaries, business profit, dividends from stock shares, and interest income from invested funds while capital gain generally comes from the sale of investment property. Congress has typically shown a preference for long-term investment by having a capital gains tax rate lower than the ordinary income rate. However, only long-term capital gains get preferential treatment; short-term capital gains (from property held for one year or less) are taxed at the same rate as ordinary income. Added complications come from various distinctions within each category. For instance, qualified dividends, which were previously taxed at ordinary income rates (as non-qualified dividends currently are), are currently taxed at long-term capital gain rates until 2011 under the Jobs and Growth Tax Relief Reconciliation Act of 2003

, and within long-term capital gains, gains on certain real estate, collectibles, and small business stock each have their own tax rates.

An individual's marginal income tax bracket
Tax bracket

Tax brackets are the divisions at which tax rates change in a progressive tax system . Essentially, they are the cutoff values for taxable income — income past a certain point will be taxed at a higher rate....
 depends upon his income and his tax-filing classification. As of 2008, there are six tax brackets for ordinary income (ranging from 10% to 35%) and four classifications: single, married filing jointly (or qualified widow or widower), married filing separately, and head of household.

An individual pays tax at a given bracket only for each dollar within that bracket's range. For example, a single taxpayer who earned $10,000 in 2009 would be taxed 10% of each dollar earned from the 1st dollar to the 8,350th dollar (10% Χ $8,350 = $835.00), then 15% of each dollar earned from the 8,351th dollar to the 10,000th dollar (15% Χ $1,650 = $247.50), for a total of $1,082.50. Notice this amount ($1,082.50) is lower than if the individual had been taxed at 15% on the full $10,000 (for a tax of $1,500). This is because the individual's marginal rate (the percentage tax on the last dollar earned, here 15%) has no effect on the income taxed at a lower bracket (here the first $8,350 of income taxed at 10%). This ensures that every rise in a person's pre-tax salary results in an increase of his after-tax salary.

However, taxpayers are not taxed on every dollar they make. For 2009, single and married filing separate taxpayers are allowed a standard deduction of $5,700. Married filing jointly and surviving widow(er)s are allowed $11,340 and head of household taxpayers are allowed $8,350. Taxpayers over 65 or blind are given an additional $1,100 standard deduction ($2,200 if over 65 and blind). A taxpayer may choose to take the standard deduction or they may itemize their deductions if the amount of itemized deductions is greater than the standard deduction.

Taxpayers are also allowed a personal exemption depending on their filing status. The personal exemption amount in 2009 is $3,650 per person.

Claiming deductions may reduce an individual's tax liability by a rate equal to the marginal tax rate of their particular tax bracket, with a corresponding reduction in returns as the individual crosses in to a lower tax bracket. For example, if an individual is able to increase the amount of their deduction by $1000 with a last-minute donation to a charitable organization, and the individual's adjusted gross income is $500 into the 25% marginal tax bracket, the donation will reduce the tax liability of the individual by ($500 Χ 25%) + ($500 Χ 15%) = $200.

The effective tax rates corresponding to the definitions above are shown in the accompanying graph.

Short-term capital gains are taxed as ordinary income rates as listed above. Long-term capital gains have lower rates corresponding to an individual’s marginal ordinary income tax rate, with special rates for a variety of capital goods.

Ordinary Income Rate Long-term Capital Gain Rate Short-term Capital Gain Rate Long-term Gain on Real Estate* Long-term Gain on Collectibles Long-term Gain on Certain Small Business Stock
10% 0% 10% 10% 10% 10%
15% 0% 15% 15% 15% 15%
25% 15% 25% 25% 25% 25%
28% 15% 28% 25% 28% 28%
33% 15% 33% 25% 28% 28%
35% 15% 35% 25% 28% 28%
* Capital gains up to $250,000 ($500,000 if filed jointly) on real estate used as primary residence are exempt.


Example of a tax computation

Income tax for year 2009:

Single taxpayer, no children, under 65 and not blind taking standard deduction;
  • $40,000 gross income - $5,300 standard deduction - $3,650 personal exemption = $31,050 taxable income
    • $8,350 Χ 10% = $835.00
    • ($31,050 - $8,350) = $22,700.00 * 15% = $3,405.00
  • Total income tax = $4,240.00 (10.6% effective tax)


Note that in addition to income tax, a wage earner would also have to pay FICA (payroll) tax (and an equal amount of FICA tax must be paid by the employer):
  • $40,000 (adjusted gross income)
    • $40,000 Χ 0.062 = $2,480 (Social Security portion)
    • $40,000 Χ 0.0145 = $580 (Medicare portion)
  • Total FICA tax = $3,060 (7.65% of income)
  • Total federal tax of individual = $7,300.00 (18.25% of income)

 Publius. In it, he explains that the wording of the "Necessary and Proper" clause should serve as guidelines for the legislation of laws regarding taxation. The legislative branch is to be the judge, but any abuse of those powers of judging can be overturned by the people, whether as states or as a larger group.

The courts have generally held that direct taxes are limited to taxes on people (variously called "capitation", "poll tax" or "head tax") and property. All other taxes are commonly referred to as "indirect taxes," because they tax an event, rather than a person or property per se. What seemed to be a straightforward limitation on the power of the legislature based on the subject of the tax proved inexact and unclear when applied to an income tax, which can be arguably viewed either as a direct or an indirect tax.

 income) were treated as direct taxes on property, and therefore had to be apportioned. Since apportionment of income taxes is impractical, this had the effect of prohibiting a federal tax on income from property. The power to tax real and personal property, or that such was a direct tax, was not denied by the Constitution. Due to the political difficulties of taxing individual wages without taxing income from property, a federal income tax was impractical from the time of the Pollock decision until the time of ratification of the Sixteenth Amendment (below).

gains, profits, and income derived from salaries, wages or compensation for personal service . . . of whatever kind and in whatever form paid, or from professions, vocations, trades, businesses, commerce, or sales, or dealings in property, whether real or personal, growing out of the ownership or use of or interest in such property; also from interest, rent, dividends, securities, or the transaction of any business carried on for gain or profit, or gains or profits and income derived from any source whatever.
(Note: this case was under the Tax Code of 1954 and the definition of income found in Title 26 sec. 61. from which our present laws derive.)

The Court held that "this language was used by Congress to exert in this field the full measure of its taxing power", id., and that "the Court has given a liberal construction to this broad phraseology in recognition of the intention of Congress to tax all gains except those specifically exempted."

The Court then enunciated what is now understood by Congress and the Courts to be the definition of taxable income, "instances of undeniable accessions to wealth, clearly realized, and over which the taxpayers have complete dominion." Id. at 431. The defendant in that case suggested that a 1954 rewording of the tax code had limited the income that could be taxed, a position which the Court rejected, stating:

The definition of gross income has been simplified, but no effect upon its present broad scope was intended. Certainly punitive damages cannot reasonably be classified as gifts, nor do they come under any other exemption provision in the Code. We would do violence to the plain meaning of the statute and restrict a clear legislative attempt to bring the taxing power to bear upon all receipts constitutionally taxable were we to say that the payments in question here are not gross income.


Tax statutes passed after the ratification of the Sixteenth Amendment in 1913 are sometimes referred to as the "modern" tax statutes. Hundreds of Congressional acts have been passed since 1913, as well as several codifications (i.e., topical reorganizations) of the statutes (see Codification

).

Central Illinois Public Service Co. v. United States, , confirmed that wages and income are not identical as far as taxes on income are concerned, because income not only includes wages, but any other gains as well. The Court in that case noted that in enacting taxation legislation, Congress "chose not to return to the inclusive language of the Tariff Act of 1913, but, specifically, 'in the interest of simplicity and ease of administration,' confined the obligation to withhold [income taxes] to 'salaries, wages, and other forms of compensation for personal services'" and that "committee reports ... stated consistently that 'wages' meant remuneration 'if paid for services performed by an employee for his employer'".

Other courts have noted this distinction in upholding the taxation not only of wages, but also of personal gain derived from other sources, recognizing some limitation to the reach of income taxation. For example, in Conner v. United States, 303 F. Supp. 1187 (S.D. Tex. 1969), aff’d in part and rev’d in part, 439 F.2d 974 (5th Cir. 1971), a couple had lost their home to a fire, and had received compensation for their loss from the insurance company, partly in the form of hotel costs reimbursed. The court acknowledged the authority of the IRS to assess taxes on all forms of payment, but did not permit taxation on the compensation provided by the insurance company, because unlike a wage or a sale of goods at a profit, this was not a gain. As the Court noted, "Congress has taxed income, not compensation".

By contrast, other courts have interpreted the Constitution as providing even broader taxation powers for Congress. In Murphy v. IRS
Murphy v. IRS

Marrita Murphy and Daniel J. Leveille, Appellants v. Internal Revenue Service and United States of America, Appellees , is a controversial tax case in which the United States Court of Appeals for the District of Columbia Circuit originally held that the taxation of emotional distress awards by the federal government is unconstitutional....
, the United States Court of Appeals for the District of Columbia Circuit upheld the Federal income tax imposed on a monetary settlement recovery that the same court had previously indicated was not income, stating: "[a]lthough the 'Congress cannot make a thing income which is not so in fact,' [ . . . ] it can label a thing income and tax it, so long as it acts within its constitutional authority, which includes not only the Sixteenth Amendment but also Article I, Sections 8 and 9."

Similarly, in Penn Mutual Indemnity Co. v. Commissioner, the United States Court of Appeals for the Third Circuit indicated that Congress could properly impose the Federal income tax on a receipt of money, regardless of what that receipt of money is called:

It could well be argued that the tax involved here [an income tax] is an "excise tax" based upon the receipt of money by the taxpayer. It certainly is not a tax on property and it certainly is not a capitation tax; therefore, it need not be apportioned. [ . . . ] Congress has the power to impose taxes generally, and if the particular imposition does not run afoul of any constitutional restrictions then the tax is lawful, call it what you will.

History of progressivity in federal income tax

The federal income tax rates in the United States have varied widely since 1913. For example, in 1954 the Congress imposed a federal income tax on individuals, with the tax imposed in layers of 24 income brackets at tax rates ranging from 20% to 91% (for a chart, see Internal Revenue Code of 1954

, federal tax revenues will always be equal to approximately 19.5% of GDP, regardless of what the top marginal tax rate is. The theory was first suggested in 1993 by Kurt Hauser, a San Francisco investment economist, who wrote at the time, "No matter what the tax rates have been, in postwar America tax revenues have remained at about 19.5% of GDP." In a May 20, 2008 editorial, the Wall St. Journal published a graph showing that even though the top marginal tax rate of federal income tax had varied between a low of 28% to a high of 91% between 1950 and 2007, federal tax revenues had indeed constantly remained at about 19.5% of GDP.

      • Treasury Notices and Announcements;

  • Tier 3
    • Legislative History
    • Private Administrative Rulings (private parties may approach the IRS directly and ask for a Private Letter Ruling on a specific issue - these rulings are binding only on the requesting taxpayer).


Where conflicts exist between various sources of tax authority, an authority in Tier 1 outweighs an authority in Tier 2 or 3. Similarly, an authority in Tier 2 outweighs an authority in Tier 3. Where conflicts exist between two authorities in the same tier, the "last-in-time rule" is applied. As the name implies, the "last-in-time rule" states that the authority that was issued later in time is controlling.

Regulations and case law serve to interpret the statutes. Additionally, various sources of law attempt to do the same thing. Revenue Rulings, for example, serves as an interpretation of how the statutes apply to a very specific set of facts. Treaties serve in an international realm.

The complexity of the U.S. income tax laws

Even venerable legal scholars like Judge Learned Hand
Learned Hand

Billings Learned Hand was an influential United States judge and judicial philosophy. He served on the United States District Court for the Southern District of New York and the United States Court of Appeals for the Second Circuit....
 have expressed amazement and frustration with the complexity of the U.S. income tax laws. In the article, Thomas Walter Swan, 57 Yale Law Journal No. 2, 167, 169 (December 1947), Judge Hand wrote:

In my own case the words of such an act as the Income Tax… merely dance before my eyes in a meaningless procession: cross-reference to cross-reference, exception upon exception — couched in abstract terms that offer [me] no handle to seize hold of [and that] leave in my mind only a confused sense of some vitally important, but successfully concealed, purport, which it is my duty to extract, but which is within my power, if at all, only after the most inordinate expenditure of time. I know that these monsters are the result of fabulous industry and ingenuity, plugging up this hole and casting out that net, against all possible evasion; yet at times I cannot help recalling a saying of William James about certain passages of Hegel: that they were no doubt written with a passion of rationality; but that one cannot help wondering whether to the reader they have any significance save that the words are strung together with syntactical correctness.


Complexity is a separate issue from flatness of rate structures. In the United States, income tax codes are often legislatures' favored policy instrument for encouraging numerous undertakings deemed socially useful — including the buying of life insurance, the funding of employee health care and pensions, the raising of children, home ownership, development of alternative energy sources and increased investment in conventional energy. Special tax rebates granted for any purpose increase complexity, irrespective of the system's flatness or lack thereof.

). Taxation of income is argued to be an infringement on that right.
