For 2014, large employers were required to report coverage on employees’ W-2 forms; small employers could do so voluntarily. Employers could also voluntarily report coverage to employees on Form 1095-B. For 2015, such reporting is mandatory for all employers providing minimum essential coverage (you’ll receive this form at the same time as your 2015 W-2).
Items, such as interest, state and local income and sales taxes, charitable contributions, and medical deductions, claimed on Schedule A of Form 1040. Itemized deductions are subtracted from adjusted gross income to arrive at taxable income. The amount of itemized deductions is also subject to a reduction when adjusted gross income exceeds certain limits.
