A tax deduction or a tax-deductible expense affects a taxpayer's income tax. A tax deduction represents an expense incurred by a taxpayer. They are variable amounts that you can subtract, or deduct, from your gross income.^[1]It is subtracted from gross income when the taxpayer computes his or her income taxes. As a result, the tax deduction will lower overall taxable income and thus lower the amount of tax paid. The exact amount of tax savings is dependent on the tax rate and can be complicated to determine. For some higher-income taxpayers, claiming all eligible tax deductions would result in having to pay the alternative minimum tax, and would result in a higher amount of tax paid.

A tax credit is a similar concept, but is different in that it reduces the tax owed, rather than reducing taxable income. This amount of tax savings is not dependent on the rate the taxpayer pays.

United States

The United States' tax system has many different types of deductions. At a high level there are "above the line" and "below the line" deductions. "The line" that these two terms refer to is a literal line on US tax forms. After calculating Total Income, the taxpayer subtracts above the line deductions to determine Adjusted Gross Income.^[2] After this, there is a solid line (and the end of the page). Below the line, each taxpayer chooses between a standard deduction or itemized deductions, whichever is larger. This is subtracted from the adjusted gross income (after being subjected to a possible phase out), to determine the taxpayer's taxable income.

Below are some examples of tax deductions. Each deduction has its own particular requirements and may depend on the taxpayer's filing status, income, and other factors. They may have separately calculated income limits where they are available or become unavailable. They may have particular rules involving prior year tax returns. The list below is not exhaustive. Most deductions can be found in 26 U.S.C. §§ 100-250.

• An exemption amount for the taxpayer, the spouse, each child, and any other qualified dependents, and certain disabilities;
• Mortgage interest paid on one's primary residence or other residence^[3];
• Qualified mortgage insurance premiums that are treated as qualified residence interest expense, for certain home loans, for mortgage insurance contracts issued on or after January 1, 2007^[4]
• Equity loan or Line of Credit interest;
• Certain taxes paid^[5];
• Charitable contributions to eligible entities^[6];
• Business deductions, such as mileage, related to an individual's expenses regarding their employment^[7];
• Business startup and operation, and farming expenses (including travel, meals, and the so-called three-martini lunch), not to exceed business income;
• Hobby expenses but only up to the gain attributable to that hobby.^[8]
• Removal of architectural barriers to the disabled and elderly;
• Union and professional dues;
• Medical expenses above a certain percentage of the individual's Adjusted Gross Income (AGI);
• The cost of tax advice, software, and books;
• Depreciation of business assets;
• Work uniforms and clothing, including such items as safety goggles or steel-toed shoes;
• Moving expenses, in some cases;
• Job search expenses as one searches for work in the same industry;
• Casualty (fire, theft) losses not covered by casualty insurance;
• Educational expense (but only if it does not prepare one for a new career);
• The oil-depletion allowance or similar for depletion of timber and other natural resources, and reforestation expenses;
• State and local taxes (i.e., income tax or property tax or use taxes);) in 2004 and 2005, one could choose between deducting State Sales Tax or alternatively deducting State Income Tax. This deduction was extended for two additional years in December 2006. [1]
• Capital losses (to a limit), such as from the sale of stock that has lost value, that exceed an individual taxpayer's capital gains in that year;
• Gambling losses (but not in excess of gambling winnings).

Many tax deductions allowed by federal law are also allowed under the tax laws of various states. Each state government may allow additional types of expenditures to be tax-deductible, such as rent in lieu of mortgage.^{[citation needed]}

Tax deductions start to "phase out" for married individuals, filing jointly, with an adjusted gross income of $159,950 or higher for the 2008 tax year;^[9] beyond that point, the full amount of the expenses cannot be deducted.

Items which behave as deductions

In addition there are various activities which have the same economic effect as income but which escape inclusion into the tax base. These include the imputed rent on owner occupied residential housing and household services provided by the non-working spouse when one man works and his spouse stays at home as a housewife. But because these items are not part of the tax base, they are not technically deductions.

United Kingdom

In the UK, Her Majesty's Revenue and Customs allow certain expenses to be deductible as necessary to complete the work from which the income was derived.

Examples of allowable expenses include:

• Professional Subscriptions
• Mileage or other expenses incurred as part of the work
• A proportion of home expenses where part of the home is used for work purposes (e.g. a self-employed person who works on a computer in the spare bedroom)
