For 2018 through 2025, the miscellaneous itemized deduction for investment-related costs is not deductible. Before 2018, these amounts were subject to the 2%-of-adjusted-gross-income floor. After 2026, such amounts may be deductible (assuming total costs exceed the 2% floor).
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.
