deduction

An expenditure that may legally be used to reduce an individual's income-tax liability. Potential deductions of particular interest to investors are expenditures for subscriptions to financial publications, a lock box for storing securities, and computer software for investment-related activities. These deductions, combined with employee business expenses and miscellaneous deductions, may be subtracted from a person's taxable income only to the extent their total exceeds 2% of that person's adjusted gross income. Interest paid on loans used to finance investments is deductible only against investment income. Also called itemized deduction, tax deduction. See also charitable contribution deduction.
