In 2012, the IRS ruled that Medicare insurance premiums can be counted. Under the ruling, Medicare premiums covering the self-employed individual – as well as his or her spouse, dependents, and under-age-27 children – are deductible as SE-health insurance. the deduction will be limited to net Self-employment income.
There are warnings on the page where the Social Security income is entered. If self-employed do not enter Medicare premiums types B, C and D here. Enter them on the business activity schedule in the section for self-employed health insurance. (Do not enter on schedule C on the line for insurance)
