Health savings accounts: the triple tax break, done right
Contributions are deductible, growth is tax free and medical withdrawals are untaxed. From 2026 a bronze or catastrophic marketplace plan can qualify you.
Quick answers
- Who can put money into a health savings account?
- Someone covered by a qualifying high deductible health plan on the first of the month, with no other disqualifying coverage, not enrolled in Medicare, and not claimable as someone's dependent.
- What can I spend it on?
- Medical care for yourself, your spouse and your dependents, to the extent insurance does not cover it. Expenses from before the account existed do not count.
- What happens if I use it for something else?
- The amount is taxed as income and an additional tax generally applies on top. You report distributions on Form 8889 whether or not they were for medical care.
A health savings account is deductible going in, untaxed while it grows, and untaxed coming out when it pays for medical care. The catch is that you can only contribute while you are covered by a qualifying high deductible health plan and almost nothing else.
What changed for 2026
A change enacted in H.R.1 treats bronze and catastrophic plans as high deductible health plans for this purpose, where the plan is available as individual coverage through a health insurance exchange. The statute applies the change to months beginning after December 31, 2025. For a reader who buys their own coverage, that can be the difference between being shut out of an account and being able to open one, so it is worth checking against the plan you already hold as well as the ones on offer at open enrollment. Publication 969 for 2025 does not yet restate this, so confirm a particular plan with the insurer and the plan document rather than assuming from the metal tier alone. What else changed on the exchanges is in marketplace insurance for 2026.
The eligibility checklist
The publication gives the test as a list, and it reads better as one:
- a qualifying high deductible health plan covers you on the first of the month;
- you carry no other health coverage beyond the kinds the rules allow;
- Medicare has not started for you; and
- nobody else can claim you as a dependent on their return.
One softening rule sits alongside them. If you qualify on the first day of your tax year's final month — December 1, for most people — and the other requirements are met, you are treated as having qualified for the whole of that year. A testing period is attached to that treatment, so anyone leaning on the last-month rule has something to keep track of afterwards.
The limits
For 2026 the annual contribution limit is $4,400 with self-only coverage and $8,750 with family coverage. The 2025 amounts, which still matter for a contribution made for last year, were $4,300 and $8,550. Anything you put in yourself comes off your income even if you never open Schedule A, which is unusual and is most of why the account is worth opening — see standard versus itemized for why that matters. Employer contributions are not included in your income. An additional contribution is allowed at older ages; check the current amount and the qualifying age before you rely on it.
What the money can pay for
Qualified medical expenses are amounts paid for medical care for you, your spouse and your dependents, and only to the extent nobody else has compensated you for them. Two rules catch people. A cost run up before the account was opened never qualifies, so the account has to exist before the bill does. And menstrual care products count: the rules place what you spend on them on the medical care side of the line. The long list of what counts as medical care in the first place belongs to medical expenses rather than here.
Insurance premiums are mostly not qualified expenses. There are exceptions, and Publication 969 lists them. If premiums are the reason you are asking, read that list rather than a summary of it.
Keep records good enough to establish three things about every distribution: that qualified medical expenses were what it paid or reimbursed, that no other source had already covered those same costs, and that no year's Schedule A has claimed them as an itemized deduction.
The cost of using it for something else
A distribution taken for any other reason is subject to income tax, and an additional tax of twenty percent may apply on top of that. There is also a trap that does not look like a withdrawal at all: certain prohibited transactions produce a deemed distribution, which is included in your income and carries the same additional tax. Either way the paperwork follows. Every withdrawal is reported by the trustee on Form 1099-SA, to you and to the IRS alike, and you account for distributions on Form 8889 with your return, whether or not they went on medical care.
Using it well
The account is portable, so it stays with you when you change employer or leave the workforce, and you are not required to withdraw anything in a given year. That combination is why a receipt filed today can support a tax-free withdrawal many years from now, and why how long to keep tax records is worth a look before you throw anything away. If a heavy year of bills has you looking at Schedule A as well, medical expenses sets out the two gates that apply there and not here.
