The Self-Employed Health Insurance Deduction in Mississippi

Short answer: if you are self-employed in Mississippi with a profit, you can deduct the health insurance you pay for yourself, your spouse, your dependents and children under 27, on Form 7206 and Schedule 1, line 17. Three limits apply: no month you could join an employer plan (yours or your spouse’s), no more than the business’s profit, and no cut to self-employment tax. Mississippi takes the same deduction on Form 80-100 (line 58), so it lowers your state tax too: 3.75% of it for 2027.

Who Qualifies in Mississippi

• You have a net profit as a sole proprietor or single-member LLC (Schedule C or F), or self-employment earnings as a partner.
• The plan is under your business. For a sole proprietor, a policy in your own name counts, from the Mississippi marketplace or a private plan.
• No employer plan was open to you that month, through your own job or your spouse’s, even one you turned down.
• The people covered are you, your spouse, your dependents, or a child under 27 at the end of the year.

The Three Limits

• The spouse ruleAny month your spouse’s employer offers you a subsidized plan is out, even if you never enrolled. Count the months carefully when a spouse changes jobs.
• The profit capNo more than the business earned after the deductible half of self-employment tax and your SEP, SIMPLE or solo 401(k) contributions. The cheapest Jackson Silver plan at 40, $10,325 a year, needs at least that much left.
• Not for SE taxIt lowers income tax only. On $72,000 of profit, self-employment tax is still about $10,173 either way.

The Deduction and the Mississippi Subsidy Line

For 2027 coverage there is no premium tax credit above 400% of the poverty line: $63,840 for one person, $132,000 for a family of four. The self-employed health insurance deduction comes off before that test, so it can move you to the right side of the line.

What It Is Worth in Mississippi for 2027

Mississippi taxes nothing on the first $10,000 of taxable income and a flat rate above it: 4% for 2026 and 3.75% for 2027. Its Form 80-100 takes the self-employed health insurance deduction you claimed federally (line 58). The marketplace in Mississippi has 3 insurers for 2027, a median of 34 plan options per county, and no PPO in any of its 82 counties: every plan is an HMO.

Bronze, Silver and Gold in Mississippi

Silver is the cheaper of the two in every Mississippi county for 2027, and Gold buys a lower deductible. In Jackson the cheapest Gold plan is $1,060 a month with a $2,500 deductible; the cheapest Silver is $860 with a $4,700 deductible. Above the subsidy line you pay the whole premium yourself, so weigh the monthly gap against the deductible you expect to use; whichever plan you choose, its full premium is what you deduct.

Bronze and an HSA. Since 2026 every Bronze plan sold through the marketplace counts as an HSA-qualified plan (IRS Notice 2026-05). In Jackson the cheapest Bronze for a 40-year-old is $718 a month with a $9,150 deductible, $1,714 a year less than the cheapest Silver. For 2027 you can also put up to $4,500 into the HSA ($9,000 with family coverage): a second deduction, on Form 8889, on top of the premiums.

Common Questions

Can I deduct health insurance if I am self-employed in Mississippi?

Yes, if your business has a net profit and you could not join an employer plan, yours or your spouse’s, that month. You deduct the premiums on Form 7206 and Schedule 1, line 17. Mississippi takes the same deduction on Form 80-100 (line 58), so it lowers your state tax too: 3.75% of it for 2027.

Can the deduction help me qualify for a premium tax credit?

It can. The deduction lowers the income tested against the 2027 subsidy line ($63,840 for one person, $132,000 for a family of four). The credit then lowers the premium you deduct, and IRS Publication 974 settles both together.

Does Mississippi allow the self-employed health insurance deduction?

Yes. Form 80-100, line 58, takes the self-employed health insurance deduction you claimed on your federal return.
