An individual must file a return if either their gross income or their adjusted gross income (AGI) was more than the yearly limit.
The United States of America is a federal republic with autonomous state and local governments. Taxes are imposed in the United States at each of these levels. These include taxes on income, payroll, property, sales, imports, estates and gifts, as well as various fees. In 2010 taxes collected by federal, state and municipal governments amounted to 24.8% of GDP. In the OECD, only Chile and Mexico taxed less as a share of GDP. The United States also has one of the most progressive tax systems in the industrialized world.
Taxes are imposed on net income of individuals and corporations by the federal, most state, and some local governments. Citizens and residents are taxed on worldwide income and allowed a credit for foreign taxes. Income subject to tax is determined under tax accounting rules, not financial accounting principles, and includes almost all income from whatever source. Most business expenses reduce taxable income, though limits apply to a few expenses. Individuals are permitted to reduce taxable income by personal allowances and certain nonbusiness expenses, including home mortgage interest, state and local taxes, charitable contributions, and medical and certain other expenses incurred above certain percentages of income. State rules for determining taxable income often differ from federal rules. Federal tax rates vary from 10% to 39.6% of taxable income. State and local tax rates vary widely by jurisdiction, from 0% to 13.30%, and many are graduated. State taxes are generally treated as a deductible expense for federal tax computation. In 2013, the top marginal tax rate for a high-income California resident would be 52.9%. Certain alternative taxes may apply. Finance
For United States individual income tax, adjusted gross income (AGI) is total gross income minus specific reductions. Taxable income is adjusted gross income minus allowances for personal exemptions and itemized deductions. For most individual tax purposes, AGI is more relevant than gross income.
Gross income is sales price of goods or property, minus cost of the property sold, plus other income. It includes wages, interest, dividends, business income, rental income, and all other types of income. Adjusted gross income is gross income less deductions from a business or rental activity and 21 other specific items. Business
Gross income in United States tax law is receipts and gains from all sources less cost of goods sold. Gross income is the starting point for determining Federal and state income tax of individuals, corporations, estates and trusts, whether resident or nonresident.
"Except as otherwise provided" by law, Gross income means "all income from whatever source," and is not limited to cash received. However, tax regulations expand on this and say "all income from whatever source derived, unless excluded by law." The amount of income recognized is generally the value received or which the taxpayer has a right to receive. Certain types of income are specifically excluded from gross income.
Public economics (or economics of the public sector) is the study of government policy through the lens of economic efficiency and equity. At its most basic level, public economics provides a framework for thinking about whether or not the government should participate in economics markets and to what extent its role should be. In order to do so, microeconomic theory is utilized to assess whether the private market is likely to provide efficient outcomes in the absence of governmental interference. Inherently, this study involves the analysis of government taxation and expenditures. This subject encompasses a host of topics including market failures, externalities, and the creation and implementation of government policy. Public economics builds on the theory of welfare economics and is ultimately used as a tool to improve social welfare.
Broad methods and topics include:
An itemized deduction is an eligible expense that individual taxpayers in the United States can report on their federal income tax returns in order to decrease their taxable income.
Most taxpayers are allowed a choice between the itemized deductions and the standard deduction. After computing their adjusted gross income (AGI), taxpayers can itemize their deductions (from a list of allowable items) and subtract those itemized deductions (and any applicable personal exemption deductions) from their AGI amount to arrive at their taxable income amount. Alternatively, they can elect to subtract the standard deduction for their filing status (and any applicable personal exemption deduction) to arrive at their taxable income. In other words, the taxpayer may generally deduct the total itemized deduction amount, or the standard deduction amount, whichever is greater. California SB
A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
