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.
An amount taken from income as a prepayment of an individual’s tax liability for the year. In the case of wages, the employer withholds part of every wage payment. Backup withholding from dividend or interest income is required if you do not provide the payer with a correct taxpayer identification number. Withholding on pensions and IRAs is automatic unless you elect to waive withholding.
