The U.S. system allows reduction of taxable income for both business and some nonbusiness expenditures, called deductions. Businesses selling goods reduce gross income directly by the cost of goods sold. In addition, businesses may deduct most types of expenses incurred in the business. Some of these deductions are subject to limitations. For example, only 50% of the amount incurred for any meals or entertainment may be deducted. The amount and timing of deductions for business expenses is determined under the taxpayer's tax accounting method, which may differ from methods used in accounting records.
