A high deductible health plan (HDHP) is any health insurance plan with an annual deductible of at least $1,700 for individual coverage or $3,400 for family coverage in 2026. But hitting that minimum deductible alone isn’t enough. The plan also has to cap your total out-of-pocket costs below a set maximum, and it needs to follow specific rules about what it covers before and after the deductible kicks in.
The IRS Dollar Thresholds for 2025 and 2026
The IRS sets the exact numbers each year, adjusting for inflation. Two requirements must be met simultaneously: the deductible must be at or above a minimum, and your total out-of-pocket spending (deductible plus copays and coinsurance, but not premiums) must stay below a ceiling.
- 2025, self-only coverage: minimum deductible of $1,650, out-of-pocket maximum of $8,300
- 2025, family coverage: minimum deductible of $3,300, out-of-pocket maximum of $16,600
- 2026, self-only coverage: minimum deductible of $1,700, out-of-pocket maximum of $8,500
- 2026, family coverage: minimum deductible of $3,400, out-of-pocket maximum of $17,000
If a plan’s deductible falls even one dollar below the minimum, or its out-of-pocket maximum exceeds the ceiling, it doesn’t qualify. The out-of-pocket limit applies only to in-network services. Costs for out-of-network care don’t count toward that cap when the plan uses a provider network.
How Family Deductibles Get Complicated
Many family plans use what’s called an “embedded” deductible, meaning each family member has their own individual deductible inside the larger family deductible. Once one person hits the individual amount, that person moves into the coinsurance phase while everyone else’s claims keep accumulating toward the family total.
Here’s the catch: if a family plan has an embedded individual deductible, that individual deductible must also meet the family-level minimum. For 2026, that means the individual deductible within a family plan needs to be at least $3,400, not the $1,700 that applies to a standalone individual plan. If either the family deductible or the embedded individual deductible falls below $3,400, the entire plan fails to qualify as an HDHP. Plans with a single, non-embedded family deductible avoid this issue because there’s no individual threshold to worry about.
Preventive Care Is the Big Exception
An HDHP can cover preventive services at no cost to you, even before you’ve paid a cent toward your deductible, without losing its HDHP status. This isn’t optional generosity from insurers. Federal law requires most plans to cover a defined set of preventive services with zero cost-sharing. That list includes blood pressure, diabetes, and cholesterol screenings, cancer screenings like mammograms and colonoscopies, routine vaccinations, well-child visits, flu shots, smoking cessation counseling, and prenatal care screenings.
Telehealth visits also now qualify for this pre-deductible treatment. Congress made permanent a provision allowing HDHPs to cover telehealth and other remote care services before the deductible is met, retroactive to the end of 2024 when a temporary version of the rule had expired. This means you can use telehealth without it jeopardizing your plan’s HDHP status or your HSA eligibility.
Why HDHP Status Matters: HSA Eligibility
The main reason people care about whether their plan qualifies as an HDHP is the health savings account. You can only contribute to an HSA if you’re enrolled in a qualifying HDHP and don’t have disqualifying coverage elsewhere. HSA contributions are tax-deductible going in, grow tax-free, and come out tax-free when spent on medical expenses. It’s one of the few accounts in the tax code with a triple tax advantage.
For 2026, the IRS allows HSA contributions of up to $4,300 for self-only coverage and $8,550 for family coverage (these figures are set annually alongside the HDHP thresholds). If you’re 55 or older, you can contribute an additional $1,000 as a catch-up contribution.
Coverage That Can Disqualify You
Being enrolled in an HDHP isn’t always enough to make you HSA-eligible. Certain other coverage can disqualify you, even if your primary plan checks every box.
A general-purpose flexible spending account (FSA) is the most common disqualifier. If you or your spouse has an FSA that reimburses broad medical expenses, you generally can’t contribute to an HSA. The same applies to a health reimbursement arrangement (HRA) that pays for qualified medical expenses before you’ve met your HDHP deductible. Limited-purpose FSAs that cover only dental and vision are fine.
You can, however, carry additional insurance for specific categories without losing HDHP status. Dental coverage, vision coverage, disability insurance, long-term care insurance, accident-only policies, and workers’ compensation are all allowed alongside an HDHP. Disease-specific policies (like a cancer-only plan) and fixed-amount hospital indemnity plans are also permitted. The key restriction: if substantially all of your health coverage comes from these supplemental policies rather than the HDHP itself, the arrangement doesn’t qualify.
Prescription drug coverage needs special attention. A separate drug plan, or a drug rider attached to your HDHP, won’t disqualify you as long as it doesn’t pay out any benefits until you’ve met the HDHP’s minimum deductible. If the drug plan covers medications before that deductible is satisfied, you lose HSA eligibility.
How VA Benefits Interact With HDHPs
If you’re a veteran enrolled in VA health care, you can still have an HDHP and use an HSA. The VA will bill and accept reimbursement from HDHPs for care related to non-service-connected conditions. You can also use your HSA funds to pay VA copayments for that non-service-connected care. Receiving VA benefits for service-connected conditions doesn’t disqualify you from HSA contributions, since that care is treated differently under the tax rules.
How to Confirm Your Plan Qualifies
Most insurers and employers label HDHP-eligible plans clearly in their benefits materials, but you can verify it yourself. Check three things: your plan’s annual deductible meets or exceeds the IRS minimum for the current year, your in-network out-of-pocket maximum doesn’t exceed the IRS ceiling, and no benefits (other than preventive care and telehealth) kick in before the deductible is met. If your plan has a family deductible with embedded individual deductibles, confirm that the individual deductible also meets the family-tier minimum. All of these figures are listed in your plan’s Summary of Benefits and Coverage document, which your insurer is required to provide.
