An HDHP, or high-deductible health plan, is a health insurance plan with a higher deductible and usually lower premiums than a traditional plan. To qualify for HSA contributions in 2026, the plan must have a deductible of at least $1,700 for self-only or $3,400 for family coverage.
Key takeaways
- HDHPs trade lower premiums for higher out-of-pocket costs before coverage kicks in.
- Only HSA-qualified HDHPs let employees contribute to a health savings account.
- Preventive care is covered before the deductible.
- 33% of covered workers were in an HDHP with a savings option in 2025.
How HDHP works
Under an HDHP, the member pays most non-preventive costs until the deductible is met, then shares costs through coinsurance until reaching the out-of-pocket maximum. To be HSA-qualified, the plan must meet IRS minimum deductibles and stay under maximum out-of-pocket limits that are adjusted each year (HealthCare.gov, High deductible health plan).
For 2026 the minimum deductible is $1,700 for self-only and $3,400 for family coverage (Davis Wright Tremaine, IRS 2026 benefit plan limits). Preventive care, such as screenings and vaccines, is covered without meeting the deductible, and recent law changes allow telehealth to be covered before the deductible too.
Employers often pair an HDHP with an employer HSA contribution, which offsets part of the deductible and helps employees accept the plan.
HDHP example
An employer offers two plans for single coverage:
| PPO | HDHP with HSA | |
|---|---|---|
| Employee premium per year | $1,800 | $600 |
| Deductible | $750 | $2,000 |
| Employer HSA contribution | none | $750 |
| Cost if the employee uses little care | $1,800 | $600, with $750 left in the HSA |
For a healthy employee, the HDHP is clearly cheaper. For someone with large expected costs, the math depends on the out-of-pocket maximum. Decision-support tools in benefits software run these comparisons for each employee.
Why HDHP matters for employers
HDHPs help employers manage premium growth. KFF reported average family premiums of $26,993 in 2025 and found that 33% of covered workers were enrolled in a high-deductible plan with a savings option (KFF 2025 Employer Health Benefits Survey). They give employees more control over spending, and HSA balances can grow over a career.
They're not a fit for everyone. Lower-wage employees and people with chronic conditions can face real hardship meeting a high deductible. Offering a choice of plans, funding the HSA, and explaining costs clearly at open enrollment keeps an HDHP strategy from turning into a retention problem.
Common HDHP mistakes to avoid
Calling any high-deductible plan HSA-eligible
The plan must meet IRS rules on deductibles, out-of-pocket maximums, and pre-deductible coverage.
Not funding the HSA
A small employer contribution makes the HDHP far more acceptable to employees.
Offering only an HDHP to a workforce with heavy medical needs
Employees with predictable high costs may pay more and resent the change.
Ignoring other coverage
A spouse's general-purpose FSA can make the employee ineligible for HSA contributions.
