Who Qualifies for the Self-Employed Health Insurance Deduction?
The self-employed health insurance deduction is specifically designed for individuals who pay for their own health insurance and are not covered by an employer's plan. To qualify, you must meet the following criteria:- Self-Employed: You must be self-employed, typically as a sole proprietor, a partner in a partnership, or a more-than-2% S-corporation shareholder. Your business must show a net profit for the year.
- Not Eligible for Employer-Sponsored Coverage: You cannot be eligible to participate in a health plan sponsored by any employer, including one offered by your spouse's employer. This eligibility is assessed month-by-month; if you were eligible for an employer plan for even one month, you cannot claim the deduction for that month.
- Premiums Paid: You must have paid the health insurance premiums yourself. The deduction covers premiums for medical, dental, and qualified long-term care insurance.
How Does the Deduction Work with HealthCare.gov Plans and Subsidies?
Many self-employed individuals in Lewistown purchase their health insurance through HealthCare.gov, Montana's federal marketplace. If you obtain coverage through the marketplace, the deduction rules interact with premium tax credits (subsidies) as follows:- No Subsidy Received: If you pay the full premium for your marketplace plan without receiving a subsidy, you can deduct 100% of the premiums you paid, subject to the "net profit" limitation (the deduction cannot exceed your net earnings from self-employment).
- Subsidy Received: If you receive an advance premium tax credit (APTC) to lower your monthly premiums, you can only deduct the portion of the premium you paid out-of-pocket, after the subsidy has been applied. For example, if your premium is $600/month and you receive a $300/month subsidy, you pay $300/month. Only this $300/month (or $3,600 annually) is deductible.
