A non-Marketplace health insurance premium is what you pay for any health plan bought outside Healthcare.gov or your state’s official exchange. The practical consequence is straightforward: federal premium tax credits and cost-sharing reductions are tied to Marketplace enrollment, so an off-exchange premium is the full, unsubsidized price. The plan itself may be identical to one sold on the exchange, with the same benefits, the same network, and the same base rate; the subsidy is what you leave on the table by buying it elsewhere.
What Counts as Off-Exchange Coverage
The dividing line is the purchasing channel. If you didn’t enroll through Healthcare.gov or a state exchange, your plan is non-Marketplace. That covers a lot of ground, and the rules differ depending on which corner of it you’re in.
Off-exchange plans fall into two broad groups. The first is ACA-compliant coverage that meets federal standards for essential health benefits, out-of-pocket maximums, and guaranteed availability regardless of health history. Insurers often sell the exact same plan on and off the Marketplace. The second group is coverage exempt from most ACA requirements because it doesn’t qualify as minimum essential coverage: short-term medical insurance, fixed indemnity policies, critical illness plans, and standalone dental or vision coverage. Federal law treats these as “excepted benefits,” which puts them outside the ACA’s consumer protection framework entirely.
Where Non-Marketplace Premiums Come From
Employer-Sponsored Plans
Employer group coverage is the largest category of non-Marketplace insurance in the country. In 2024, employment-based coverage reached roughly 54 percent of the population.1U.S. Census Bureau. Health Insurance Coverage in the United States: 2024 You and your employer share the cost, with your portion coming out of each paycheck. The full premium is usually much higher than the line item on your pay stub, because the employer typically covers most of it.
That payroll deduction normally runs on a pre-tax basis through a Section 125 cafeteria plan. Your contribution is excluded from federal income tax, Social Security tax, and Medicare tax, which makes employer coverage effectively cheaper than paying the same dollar amount from after-tax income.2Internal Revenue Service. FAQs for Government Entities Regarding Cafeteria Plans That tax advantage is one reason employer coverage remains popular even without access to Marketplace subsidies.
What matters for ACA purposes is whether your share of the premium is “affordable” under IRS rules, defined for 2026 plan years as costing no more than 9.96 percent of household income.3Internal Revenue Service. Revenue Procedure 2025-25 If your employer’s offer exceeds that threshold, you may qualify for premium tax credits on the Marketplace instead.
COBRA Continuation Coverage
If you lose a job or have your hours reduced, COBRA lets you keep your employer’s group plan temporarily. The premium shock is real: you pay the full cost, including the portion the employer used to cover, plus a 2 percent administrative fee.4U.S. Department of Labor. COBRA Continuation Coverage Standard COBRA runs up to 18 months after a job loss or reduction in hours, with longer windows in certain qualifying events.5Office of the Law Revision Counsel. 29 USC 1162 – Continuation Coverage
Off-Exchange Individual Plans
You can buy an ACA-compliant individual plan directly from an insurer or through a broker without ever touching the Marketplace. The plan carries the same essential health benefits, the same out-of-pocket limits, and the same ban on medical underwriting as its on-exchange twin. The base premium is the same. What’s missing is the premium tax credit.
Short-Term and Other Non-ACA Plans
Short-term, limited-duration insurance is designed to fill temporary gaps, not replace comprehensive coverage. Under the 2024 federal rule, these plans are capped at a three-month initial term with a maximum total period of four months including renewals. The federal government announced in 2025 that it would not prioritize enforcement of those duration limits, and new rulemaking was expected in 2026. Some insurers in some states still sell longer-duration short-term plans, while roughly ten states either prohibit them outright or impose stricter limits than the federal rule.
Because short-term plans don’t qualify as minimum essential coverage, insurers can use medical underwriting to set your premium or to deny coverage based on pre-existing conditions. A healthy applicant may see a much lower premium than on an ACA plan; someone with a chronic condition may face a steep surcharge or a flat rejection. Fixed indemnity plans, which pay a set dollar amount per medical event rather than a percentage of actual costs, work the same way and carry the same lack of ACA protections.
Medicare and Medicaid
Both sit outside the Marketplace. The standard Medicare Part B premium for 2026 is $202.90 per month.6Medicare.gov. 2026 Medicare Costs Higher-income beneficiaries pay an income-related monthly adjustment amount (IRMAA) on top of the base, calculated from modified adjusted gross income two years prior.7Social Security Administration. SSA POMS HI 01101.031 – How IRMAA Is Calculated and How IRMAA Affects the Total Medicare Premium Medicaid premiums, where they exist, are nominal or zero for eligible low-income individuals and are set by state programs.
How the Premium Is Priced
Pricing rules depend entirely on which type of off-exchange plan you have.
For ACA-compliant plans sold off the exchange, insurers can only adjust premiums based on four factors: age, geographic location, family size, and tobacco use.8Centers for Medicare & Medicaid Services. Market Rating Reforms Health status, gender, and medical history are off limits. Age-based pricing is capped so the oldest adults pay no more than three times what the youngest adults pay. Tobacco surcharges can add up to 50 percent on top of the base premium.9HealthCare.gov. How Health Insurance Marketplace Plans Set Your Premiums These are the same rules that apply to Marketplace plans, which is why the base price for an identical plan matches on and off the exchange.
Non-ACA plans operate on a different model. Because they’re exempt from guaranteed-issue requirements, insurers can review your medical history, current conditions, and prescription drug use before quoting a price. Two people the same age in the same ZIP code can receive very different prices based on health history alone.
Employer group premiums come from negotiations between the employer and the insurer, or, for self-insured plans, from the employer’s own claims experience. The employee contribution is whatever the employer decides to charge, and it varies widely from one company to the next.
Why Subsidies Don’t Apply Off-Exchange
The premium tax credit is the main federal subsidy that lowers health insurance costs for low- and moderate-income households, and it’s only available if you enroll through the Marketplace. The statute explicitly requires the plan to be “enrolled in through an Exchange” to qualify for the credit.10Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan Buying the identical plan directly from the same insurer means paying the full price.11Internal Revenue Service. Eligibility for the Premium Tax Credit
Cost-sharing reductions are tighter still. They lower deductibles, copays, and out-of-pocket maximums, and you must enroll in a Silver-tier plan through the Marketplace to receive them.12HealthCare.gov. Cost-Sharing Reductions No other metal tier qualifies, and no off-exchange purchase qualifies. For someone whose income makes them eligible, a Silver plan with cost-sharing reductions can carry dramatically lower out-of-pocket costs than the same plan bought directly. That is where the real money gets left on the table.
Tax Breaks That Still Apply
Even without premium tax credits, non-Marketplace premiums can reduce your tax bill in two ways.
If you’re self-employed and pay for your own coverage, you can deduct 100 percent of the premiums as an above-the-line deduction. It reduces adjusted gross income directly, and you don’t need to itemize. The deduction covers medical, dental, and long-term care premiums for you, your spouse, your dependents, and your children under 27. Two limits apply: the deduction can’t exceed your net self-employment income for the year, and you can’t claim it for any month you were eligible for an employer-sponsored plan, including one offered through a spouse.
If you aren’t self-employed and pay off-exchange premiums out of pocket, those premiums count as medical expenses on Schedule A. You can only deduct the portion of total medical and dental expenses that exceeds 7.5 percent of adjusted gross income.13Internal Revenue Service. Publication 502 – Medical and Dental Expenses For most people, premiums alone don’t clear that floor, but a year with significant medical bills can push the total over. Premiums paid pre-tax through an employer plan don’t qualify, and neither do amounts already covered by another credit or deduction.
Employer Reimbursement Arrangements
Some employers, especially smaller ones, skip the traditional group plan and instead reimburse employees for individual health insurance through a health reimbursement arrangement, or HRA. Two kinds matter here.
A Qualified Small Employer HRA (QSEHRA) is available to employers with fewer than 50 full-time employees that don’t offer a group plan. The employer sets a monthly allowance, and employees submit receipts for individual premiums for tax-free reimbursement. For 2026, the IRS caps annual QSEHRA reimbursements at $6,450 for self-only coverage and $13,100 for family coverage. An employee eligible for a QSEHRA who also receives premium tax credits must reduce the credit by the amount of the QSEHRA allowance.
An Individual Coverage HRA (ICHRA) works similarly but has no employer size limit and no cap on reimbursement amounts. The employer defines eligible employee classes and the allowance for each. Employees buy their own individual plan and submit claims. The important wrinkle: if your employer offers an ICHRA that’s considered affordable, you can’t get premium tax credits on the Marketplace. If the ICHRA isn’t affordable, you can decline it and use the Marketplace with subsidies instead.14HealthCare.gov. Marketplace Coverage and HRAs
A Boundary Worth Noting: State Individual Mandates
The federal individual mandate penalty for going uninsured dropped to $0 starting in 2019. A handful of states and the District of Columbia still impose their own penalties. If you live in one of those states and choose a non-ACA plan that doesn’t count as minimum essential coverage, you could face a state tax penalty on top of paying your premium. Check your state’s requirements before settling on a short-term or limited-benefit plan.
