This article is a brief overview of some aspects of US taxes.

1 Overview

Taxation in the United States may involve payments to at least four different levels of government: local government (possibly including one or more of municipal, township, district and county governments), regional entities (school, utility and transit districts) state government, and the federal government. Local government is financed by value based property taxes (which may vary depending upon when the parcel was purchased or the manner of property transfer) while additional taxes may be in the form of fixed parcel taxs, fees (e.g. building permits, which may reflect the added capital cost and operating costs of services such as schools, parks, etc.), fines (particularly parking and traffic tickets), sometimes income tax, sometimes a gross receipts or gross payroll tax, and sometimes by a portion of sales taxes collected by the state, a tax which may vary among jurisdictions (particularly counties) within the state and which may exclude or include specific items or services, depending upon the state and for food, may be excluded, included for restaurants and possibly excluded for food not eaten at the serving location. In California, starter plants and trees obtained from a garden center are taxed if adjudged for decorative purposes while plants for food production are untaxed, as is food in this state.

States permit the creation of special assessment districts (typically for provision of water or removal of sewage, or for parks, public transit or schools) whose boundaries may be independent of other boundaries and whose income may be from one or more of service assessments, property taxes, parcel taxes, a portion of road or bridge tolls, or an additional increment upon sales taxes in addition to the non–tax fees for services provided (such as metered water). State government is financed mainly by a mix of sales and/or income taxes and to a lesser extent by corporate registration fees, certain excise taxes, and automobile license fees.

The federal government is now financed primarily by personal and corporate income taxes, with the original funding via tariffs upon imported goods now representing only a minor portion of federal income. There are also non–tax "fees" to recompense agencies for services or to fill specific trust funds such as that placed upon airline tickets for airport expansion and air traffic control. Often the receipts intended to be placed "trust" funds are used for other purposes, with the government posting an IOU ('I own you') in the form of a federal bond or other accounting instrument, then spending the money on unrelated current expenditures. Federal excise taxes are applied to specific items such as motor fuels, tires, telephone usage, tobacco products, alcoholic beverages, etc., often but not always allocated to special funds related to the object or activity taxed. Social security income taxes are taken from earned income (wages), but not from other sources of income (e.g. interest and dividends), and the amount of earned income subject to the tax is limited at the upper end with the social security taxes on low income earners ameliorated by an earned income tax credit, essentially a negative tax.

There is also "medicare" taxes, a system parallel to social security. The employer must make an equal contribution to these taxes. Self employed persons must pay both portions. There are also estate taxes, applicable mostly to wealthy families. Certain capital gains are taxed while others are not taxed or taxed above specific levels dependent upon various asset classes.

Most complexity in taxes at the federal level is due to numerous special exclusions of or specific tax rates for certain kinds of income, tax deductions and tax credits for specific expenditures, taxes to state and local jurisdictions, home mortgage interest but not other debt interest (e.g. credit card or automobile finance debt) such as would generally be useful to a lower income person, and an alternative minimum tax, which negates the effectiveness of most of these exclusions, deductions, and credits, particularly for middle income families with a large families and high mortgage debt who also reside in high tax states.

Depending upon the amount of additional income, Social Security payments may be untaxed or partially taxed, dependent upon the nature and level of other income. In some cases marginal tax rates combined with other benefit losses such as the provision of medical care for indigent persons may result in effective marginal taxation exceeding 100 percent, although these effects are usually seen at the lower end of the income range. Conversely, due to tax shelters and untaxed income such as that from municipal and state bonds, the taxation rates for the upper income ranges will generally decline well below that seen by middle income wage earners and for prosperous corporations may actually in effect be negative, largely due to accounting manipulations that take advantage of special interest loopholes in the tax laws.
