What limits the self-employed health insurance deduction?

The self-employed health insurance deduction is specifically limited by the net self-employment profit. When calculating this deduction, self-employed individuals can deduct premiums paid for health insurance from their taxable income, but only to the extent that their net self-employment profit allows. This means that if a self-employed person has a net loss or their net profit is less than the total amount of health insurance premiums paid, the deduction will be limited to the amount of their net profit.

Understanding this limit is crucial because it affects how much one can effectively reduce their taxable income by using the health insurance deduction. If the net profit is zero or negative, no deduction can be taken for health insurance costs. This mechanism ensures that taxpayers are not able to claim more in deductions than the income they earn through their self-employment activities.
