To
deduct health insurance as a business expense, the policy must be in your name or the business name.
If you or your spouse could
participate (even if you declined coverage) in an employer's health plan at any
time during a given month, you cannot take the deduction for that month.
However, payments for those months are deductible on Schedule A if you itemize
deductions.
Your deduction for self-employed health
insurance is limited to net income on your Schedule C less the deductible part
of your self-employment tax (Form 1040 line 29), less contributions to a qualified retirement plan. Any extra
self-employed health insurance payments will be included with your medical
expenses on Schedule A, Itemized Deductions
