Definition of nonbusiness expense deduction

broad category of deductions, such as state and local sales taxes and certain miscellaneous deductions. Individuals cannot take an itemized deduction for state and local sales taxes. Also, no deduction is allowed for expenses related to attending a convention, seminar, or similar meeting unless such expenses are connected with a trade or business. Thus expenses for a convention, or for a meeting in connection with investments, financial planning, or other income-producing activity, will no longer be deductible. Certain miscellaneous itemized deductions, including unreimbursed employee business expenses, are deductible by individuals only if the aggregate amount of the deductions exceeds two percent of the taxpayer's adjusted gross income (AGI)
