| Coverage | 2025 | 2026 |
|---|---|---|
| Self-only | $4,300 | $4,400 |

Limits include employer contributions. For 2026, the IRS defines an HDHP as having an annual deductible of at least $1,700 for self-only coverage or $3,400 for family coverage, with out-of-pocket maximums of $8,500 and $17,000. Legislation in 2025 also expanded HSA eligibility in some situations (for certain plans and arrangements); check IRS guidance if you have unusual coverage.
Who is eligible?
- You are covered by a qualifying HDHP.
- You have no other disqualifying health coverage (with exceptions).
- You are not enrolled in Medicare.
- You can’t be claimed as someone else’s dependent.
How the deduction works
If you contribute directly (not through payroll), you can deduct the amount as an adjustment to income on Form 1040 — an above-the-line deduction available whether or not you itemize. Contributions through payroll deduction are pre-tax and already excluded from your taxable wages; you don’t deduct them again. Report contributions and distributions on Form 8889.
Deadline
You can generally make contributions for a tax year until the tax filing deadline of the following year (April 15, not extended). Tell your HSA custodian which year the contribution is for.
Qualified distributions
Withdrawals for qualified medical expenses — doctor visits, prescriptions, dental, vision and others — are tax-free. If you withdraw money for non-medical purposes before 65, the amount is taxable and generally subject to an additional 20% tax; after 65, non-medical withdrawals are taxed as ordinary income without the penalty.
Using the HSA as a long-term account
Many people invest HSA funds and pay current medical bills out of pocket, saving receipts so they can reimburse themselves tax-free later. This is a legitimate strategy but requires careful recordkeeping.
Mid-year enrollment
If you become eligible mid-year, the “last-month rule” may allow a full-year contribution if you stay eligible through the testing period. Mistakes can lead to excess contributions and penalties; read the IRS instructions or consult a professional.
State taxes
A few states don’t follow the federal tax treatment of HSAs. Check your state revenue agency.
Common HSA mistakes
- Contributing while on Medicare. Once you’re enrolled in Medicare you can’t make new HSA contributions, though you can still use existing funds.
- Exceeding the limit through payroll plus personal deposits. Employer and employee contributions are combined; excess contributions are taxable and may carry a penalty unless withdrawn in time.
- Using HSA money for non-qualified expenses. That triggers income tax and, before 65, an additional 20% tax.
- Forgetting Form 8889. You must file it with your return if you made or received HSA contributions or distributions.
