2026 HSA Contribution Limits and Eligibility Checklist

For calendar year 2026, the IRS HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage. Eligible individuals age 55 or older may generally make an additional $1,000 catch-up contribution. Eligibility and prorating can change the amount a person may actually contribute.

2026 HDHP thresholds

IRS Revenue Procedure 2025-19 defines a 2026 high-deductible health plan as having a deductible of at least $1,700 for self-only coverage or $3,400 for family coverage. Maximum annual out-of-pocket expenses are $8,500 for self-only coverage and $17,000 for family coverage, excluding premiums.

Eligibility is more than the deductible

Generally, an HSA contributor must be covered by a qualifying HDHP and have no disqualifying other coverage. Medicare enrollment, being claimable as another person’s dependent, and many general-purpose health FSAs or HRAs can affect eligibility. Recent federal changes also affect certain direct-primary-care and telehealth arrangements, so use current IRS guidance rather than an older checklist.

Contributions from all sources share the limit

Employee payroll contributions, direct personal contributions and employer contributions generally count toward the same annual limit. A spouse’s catch-up contribution must go to that spouse’s HSA. Midyear eligibility changes can require monthly prorating unless a specific rule applies, and the last-month rule carries a testing period.

Tax treatment

• Eligible payroll contributions may receive favorable federal payroll-tax treatment.
• Eligible direct contributions may be deductible for federal income-tax purposes.
• Earnings can grow tax-deferred.
• Distributions for qualified medical expenses can be federally tax-free.

State tax treatment is not uniform. Confirm the rules for the taxpayer’s state.

Practical checklist

1. Confirm the plan is HSA-qualified, not merely labeled high deductible.
2. Check all other medical coverage.
3. Total employer and employee contributions together.
4. Account for months of eligibility and any testing period.
5. Coordinate catch-up contributions between spouses.
6. Keep receipts and Forms 5498-SA and 1099-SA.
