Federal courts have long held that expenses incurred by taxpayers for the care of dependents, such as a daycare or babysitting expense, while the taxpayer is away from home and at work, are not deductible under I.R.C. § 162(a). However, taxpayers who incur daycare expenses for their children or disabled adult dependents may be eligible for a federal tax credit of up to 35% percent of the cost of day care. To qualify for the child and dependent care credit, you must have a dependent child age 12 or younger, or a dependent of any age who cannot care for himself or herself. You may calculate your tax credit on IRS Form 2441.
