An HSA is the only account in the US tax code that goes in untaxed, grows untaxed and comes out untaxed when it is spent on qualifying medical care. Nothing else does all three. The catch is that you cannot simply open one — you have to be covered by a health plan that qualifies, and most plans do not.
I am Scott Binsack, a licensed insurance producer, NPN 20492859. I am not your tax adviser and nothing here is tax advice; what follows is what the plan has to look like for the account to be available to you at all.
The 2026 numbers
The IRS set these in Revenue Procedure 2025-19. They are the thresholds, not a plan’s actual figures — a plan can have a higher deductible than the minimum and still qualify.
| 2026 | Self-only | Family |
|---|---|---|
| Maximum HSA contribution | $4,400 | $8,750 |
| Minimum plan deductible to qualify | $1,700 | $3,400 |
| Maximum plan out-of-pocket | $8,500 | $17,000 |
If you are 55 or older you can add a further $1,000 catch-up contribution.
What makes a plan HSA-eligible
Three things have to be true at once, and the third is the one people fall over.
One. The plan is a qualified high deductible health plan — it meets the minimum deductible above and stays inside the out-of-pocket maximum.
Two. With narrow exceptions, the plan does not pay for anything before the deductible is met. Preventive care is the main carve-out. A plan with a deductible over $1,700 that also gives you $30 office visits from day one is generally not HSA-eligible, and it is the most common reason a plan people assumed qualified turns out not to.
Three. You have no other disqualifying coverage. Being enrolled in Medicare disqualifies you. A general-purpose health FSA — yours or your spouse’s — disqualifies you. Being claimed as someone else’s dependant disqualifies you.
Marketplace plans can be HSA-eligible and healthcare.gov has a filter for it. Not every plan carrying a large deductible is one, so the filter is worth more than the assumption.
Who this genuinely suits
The self-employed household in good health with the cash flow to absorb a bad year. That is the honest profile. You trade a lower premium and a tax-advantaged account against real exposure if something happens, and the trade only works if you would actually fund the account rather than just enjoy the cheaper premium.
The account is yours, permanently. It is not an FSA — nothing is forfeited at the end of the year, it follows you between jobs and plans, and after 65 it can be withdrawn for non-medical purposes at ordinary income rates, which makes it function as a second retirement account you happened to build by staying healthy.
Who this does not suit
If a $1,700 deductible arriving in February would be a genuine problem for you, this is the wrong structure regardless of how attractive the tax treatment is. A high deductible plan you cannot afford to use is not insurance, it is a monthly payment.
Likewise if you are approaching Medicare: contributions have to stop, and the timing interacts with when Medicare coverage begins. Get that sequencing from your tax adviser before the year you turn 65, not during it.
What I do with this
I tell you which of the plans available at your address actually qualify — verified, not assumed — and what each one costs. What you then contribute, and how it fits your tax position, is between you and your accountant. Plenty of people should not be doing this. I will say so.
No fee. Carriers pay the commission and it is inside the premium either way.
