Although the actual definitions vary between jurisdictions, in general, a direct tax or income tax is a tax imposed upon a person or property as distinct from a tax imposed upon a transaction, which is described as an indirect tax. There is a distinction between direct and indirect tax depending on whether the tax payer is the actual taxpayer or if the amount of tax is supported by a third party, usually a client. The term may be used in economic and political analyses, but does not itself have any legal implications. However, in the United States, the term has special constitutional significance because of a provision in the U.S. Constitution that any direct taxes imposed by the national government be apportioned among the states on the basis of population. In the European Union direct taxation remains the sole responsibility of member states.
For households and individuals, gross income is the sum of all wages, salaries, profits, interest payments, rents, and other forms of earnings, before any deductions or taxes. It is opposed to net income, defined as the gross income minus taxes and other deductions.
Income taxes in the United States are imposed by the federal government, and most states. The income taxes are determined by applying a tax rate, which may increase as income increases, to taxable income, which is the total income less allowable deductions. Income is broadly defined. Individuals and corporations are directly taxable, and estates and trusts may be taxable on undistributed income. Partnerships are not taxed, but their partners are taxed on their shares of partnership income. Residents and citizens are taxed on worldwide income, while nonresidents are taxed only on income within the jurisdiction. Several types of credits reduce tax, and some types of credits may exceed tax before credits. An alternative tax applies at the federal and some state levels.
Section 61 of the Internal Revenue Code defines "gross income," the starting point for determining which items of income are taxable for federal income tax purposes in the United States. Section 61 states that "[e]xcept as otherwise provided in this subtitle, gross income means all income from whatever source derived [. .. ]". The United States Supreme Court has interpreted this to mean that Congress intended to express its full power to tax incomes to the extent that such taxation is permitted under Article I, Section 8, Clause 1 of the Constitution of the United States and under the Constitution's Sixteenth Amendment.

Tax protesters in the United States have advanced a number of arguments asserting that the assessment and collection of the federal income tax violates statutes enacted by the United States Congress and signed into law by the President. Such arguments generally claim that certain statutes fail to create a duty to pay taxes, that such statutes do not impose the income tax on wages or other types of income claimed by the tax protesters, or that provisions within a given statute exempt the tax protesters from a duty to pay.

Tax protesters in the United States advance a number of constitutional arguments asserting that the imposition, assessment and collection of the federal income tax violates the United States Constitution. These kinds of arguments, though related to, are distinguished from statutory and administrative arguments, which presuppose the constitutionality of the income tax, as well as from general conspiracy arguments, which are based upon the proposition that the three branches of the federal government are involved together in a deliberate, on-going campaign of deception for the purpose of defrauding individuals or entities of their wealth or profits. Although constitutional challenges to U.S. tax laws are frequently directed towards the validity and effect of the Sixteenth Amendment, assertions that the income tax violates various other provisions of the Constitution have been made as well.
