An expense allowed as a reduction of taxable income.The most common individual deductions are for home mortgage interest,ad valorem and sales taxes,moving expenses associated with a job, charitable giving, and health-care costs. Virtually all expenses associated with income-producing property are deductible, including noncash expenses such as depreciation. Virtually all operating expenses for a business are deductible, except that capital expenditures (a new roof, expansion of building, purchase of equipment) must be capitalized and depreciated over time unless falling within the Section 179 limits. Section 179 lets a taxpayer deduct as expenses certain things that would otherwise have to be capitalized.
