Deducting Your Spouse and Kids’ Health Insurance as a Business Owner in 2027
Most self-employed owners know they can deduct their own health insurance premiums. Fewer realize the deduction covers the whole household: your spouse, your dependents, and any child under 27 — even a non-dependent child. For an owner covering a family in 2027, that can turn a $20,000-plus annual premium bill into one of the largest deductions on the return.
Here is whose premiums qualify, whether one family plan or separate policies works better, and the spouse-employer-plan trap that wipes out the deduction for entire months.

Whose Premiums Qualify
The deduction covers premiums for yourself, your spouse, your dependents, and any child under 27 — even if not your dependent, even if married, even if living independently. A 25-year-old on your family plan generates deductible premiums whether or not you claim them.
Coverage can be marketplace, group, COBRA, or private health insurance for self-employed families off the exchange. The source does not matter — your self-employment status and who paid do.
One Family Plan vs Separate Policies
Both approaches produce deductible premiums, but the economics differ — especially with private underwritten plans in the mix.
One family private PPO: Simpler — one premium, one deductible structure. A healthy family might pay $1,100–$1,500/month for a private underwritten family PPO in 2027, versus $2,500+ for a full-price marketplace family plan. The entire premium is deductible (subject to the profit cap and employer-plan exclusion).
Separate individual policies: Each member is underwritten individually. This can be 10–20 percent cheaper when risk profiles differ sharply — two healthy parents at preferred rates plus an inexpensive individual plan for a young adult child, for example. Each person can also choose their own deductible. More admin, sometimes meaningfully lower total cost.
Considerations for 2027: underwriting is per-person on individual policies, so if one member has a major condition, the healthy members can keep preferred private rates while that member uses guaranteed-issue marketplace coverage. The deduction aggregates either way — one $18,000 family premium or three policies totaling $15,000 flow to Form 7206 identically. And a 24-year-old’s separate individual premium remains deductible on your return even if they file their own taxes.
The Spouse-Employer-Plan Trap
The rule that destroys more family deductions than any other: for any month you are eligible for a health plan subsidized by your employer or your spouse’s employer, no deduction that month. Eligibility — not enrollment — is the test.
For owners with a working spouse, this needs month-by-month attention in 2027. If your spouse’s employer offers family coverage you are eligible for — even declined because your private plan is better — the deduction is gone for those months. A spouse starting a benefitted job in August means your deduction runs January through July only.
The strategic wrinkle: some couples have the working spouse decline employer family coverage because the owner’s private family plan is cheaper and better — but mere eligibility still kills those months. Sometimes enrolling the working spouse solo in the employer plan (keeping the family on the private plan) changes the eligibility picture. Model the scenarios with your CPA before open enrollment, not after.
The Net-Profit Cap at Family Scale
The deduction cannot exceed business net profit, with no carryforward. A solo owner netting $60,000 with $22,000 in family premiums deducts the full $22,000. But $15,000 of profit against $20,000 in premiums means only $15,000 is deductible.
In volatile years, this is another argument for keeping premiums low while maintaining good coverage: a private family plan at $1,200/month versus $2,400/month on the marketplace does not just save $14,400 in cash — it keeps the deduction under the profit cap in lean years. S-corp owners: the corporation must pay or reimburse the full family premiums and report the total in Box 1 of your W-2 — confirm the entire family amount, not just employee-only, is captured before year-end.
Adult Children on Your Plan
Children can stay on a parent’s plan until 26, and the deduction follows the under-27 rule. Premiums for a 24-year-old on your family private plan are deductible even if the child earns their own income and files independently. Once a child turns 27, their premiums are no longer deductible on your return — though they may be on the child’s own return if self-employed. And when a 26-year-old ages off mid-year, they can move to their own individual private plan with year-round enrollment instead of waiting for open enrollment.
The Bottom Line
For business owners covering a family in 2027, the premium deduction is a household-level benefit that can reach $15,000–$25,000. The keys: know whose premiums count, watch the spouse-employer eligibility trap month by month, and mind the profit cap. The deduction applies equally to marketplace and private plans, so shop for the lowest true cost first — the cheaper sticker price almost always means the cheaper after-tax cost. Here is how to get private health insurance for your family and check who qualifies.
