A tax deduction is an amount deducted from taxable income, usually based on expenses such as those incurred to produce additional income. Tax deductions are a form of tax incentives, along with exemptions and tax credits. The difference between deductions, exemptions, and credits is that deductions and exemptions both reduce taxable income, while credits reduce tax.
Under United States tax law, itemized deductions are eligible expenses that individual taxpayers can claim on federal income tax returns and which decrease their taxable income, and are claimable in place of a standard deduction, if available.
Charitable contribution deductions for United States Federal Income Tax purposes are defined in section 170(c) of the Internal Revenue Code as contributions to or for the use of certain nonprofit enterprises.
In the United States income tax system, adjusted gross income (AGI) is an individual's total gross income minus specific deductions. It is used to calculate taxable income, which is AGI minus allowances for personal exemptions and itemized deductions. For most individual tax purposes, AGI is more relevant than gross income.
The Internal Revenue Code of 1986 (IRC), is the domestic portion of federal statutory tax law in the United States. It is codified in statute as Title 26 of the United States Code. The IRC is organized topically into subtitles and sections, covering federal income tax in the United States, payroll taxes, estate taxes, gift taxes, and excise taxes; as well as procedure and administration. The Code's implementing federal agency is the Internal Revenue Service.
The United States federal government and most state governments impose an income tax. They 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. Most business expenses are deductible. Individuals may deduct certain personal expenses, including home mortgage interest, state taxes, contributions to charity, and some other items. Some deductions are subject to limits, and an Alternative Minimum Tax (AMT) applies at the federal and some state levels.
Section 1 of the Internal Revenue Code, titled "Tax Imposed" is the law that imposes a federal income tax on taxable income, and sets forth the amount of the tax to be paid. A similar tax on corporations is set forth in IRC §11.
The Household and Dependent Care Credit is a nonrefundable tax credit available to United States taxpayers. Taxpayers that care for a qualifying individual are eligible. The purpose of the credit is to allow the taxpayer to be gainfully employed. This credit is created by 26 U.S. Code (U.S.C) § 21, section 21 of the Internal Revenue Code (IRC).
Rules concerning income tax and gambling vary internationally.
Treasury Regulation 1.183-2 is a Treasury Regulation in the United States, outlining the taxes owed from income deriving from non-business, non-investment activity. Expenses relating to for profit activities, such as business and investment activities, are generally tax deductible under sections 162 and 212, respectively, of the Internal Revenue Code. However, expenses relating to not for profit activities, such as hobbies, are generally not tax deductible.
Under United States tax law, certain performing artists are eligible to deduct the expenses incurred in the course of their employment as performing artists. The deduction itself is provided by IRC § 62(a)(2)(B), while qualifications of a Qualified Performing Artist ("QPA") are provided by IRC § 62(b).
Under the United States taxation system, an enterprise may deduct business expenses from its taxable income, subject to certain conditions. On occasion the Internal Revenue Service (IRS) has challenged such deductions, regarding the activities in question as illegitimate, and in certain circumstances the Internal Revenue Code provides for such challenge. Rulings by the U.S. Supreme Court have in general upheld the deductions, where there is not a specific governmental policy in support of disallowing them.
A casualty loss is a type of tax loss that is a sudden, unexpected, or unusual event. Damage or loss resulting from progressive deterioration of property through a steadily operating cause would not be a casualty loss. “Other casualty” are events similar to “fire, storm, or shipwreck.” It is generally held that wherever force is applied to property which the owner-taxpayer is either unaware of because of the hidden nature of such application or is powerless to act to prevent the same because of the suddenness thereof or some other disability and damage results.
Section 183 of the United States Internal Revenue Code, sometimes referred to as the "hobby loss rule," limits the losses that can be deducted from income which are attributable to hobbies and other not-for-profit activities. Generally, losses which occur in for-profit activities are not limited and can be used to offset other income from other activities. But the § 183 limitation curtails those deductions when the activity is deemed a hobby.
In the United States tax system, the two-percent haircut, otherwise known as the two-percent floor, is a limitation on miscellaneous itemized income tax deductions and is codified under Internal Revenue Code IRC § 67(a).
For taxation in the United States, the Limits on Depreciation Deduction was enacted to limit certain deductions on depreciable assets. Section 280F is a policy that makes the Internal Revenue Code more accurate by allowing a taxpayer to report their business use on an asset they may also need for some personal reasons.
Grynberg v. Commissioner, 83 T.C. 255 (1984) was a case in which the United States Tax Court held that one taxpayer's prepaid business expenses were not ordinary and necessary expenses of the years in which they were made, and therefore the prepayments were not tax deductible. Taxpayers in the United States often seek to maximize their income and decrease their tax liability by prepaying deductible expenses and taking a deduction earlier rather than in a later tax year.
Taxation of illegal income in the United States arises from the provisions of the Internal Revenue Code, enacted by the U.S. Congress in part for the purpose of taxing net income. As such, a person's taxable income will generally be subject to the same federal income tax rules, regardless of whether the income was obtained legally or illegally.
In the United States federal income tax, a Vacation home deduction is a tax deduction to be claimed on an individual taxpayer's vacation home.
The alternative minimum tax (AMT) is a tax imposed by the United States federal government in addition to the regular income tax for certain individuals, estates, and trusts. As of tax year 2018, the AMT raises about $5.2 billion, or 0.4% of all federal income tax revenue, affecting 0.1% of taxpayers, mostly in the upper income ranges.
