Unreimbursed employee business expenses used to be a miscellaneous itemized deduction subject to the 2% of adjusted gross income floor. However, this deduction has been suspended for 2018 through 2025, so no deduction is currently allowable.
A fixed deduction allowed to every taxpayer, except those who may be claimed as a dependent by another person. Extra exemption deductions are allowed for a spouse on a joint return and for each qualifying dependent. A deduction of $3,400 is allowed for each exemption claimed on 2007 returns, but the deduction is phased out for certain high income individuals.
