You may be able to use the Self-Employed Health Insurance (SEHI) deduction if you're at least a 2% shareholder in an S Corporation. To claim this deduction, the health insurance premiums must be paid or reimbursed by the S corporation and reported as taxable compensation in box 1 of your W-2.
The S Corporation can either purchase the policy in your name or reimburse you for the premiums you paid. The policy can also cover your spouse, dependents, and any nondependent children under the age of 27.
The SEHI deduction is generally more advantageous than claiming it as a "regular" itemized deduction. The SEHI deduction will appear on line 16 of Schedule 1 and may not exceed your W-2, box 5 amount.
