HSA and FSA Limits 2026: Whose Election Blocks Yours?

Every page on this subject prints the same four numbers. The numbers are the easy part and they are on the IRS website. The part that decides whether any of them apply to you is a coverage test, and the input to that test is often a form your spouse filled in at their own open enrolment.

What are the 2026 HSA and FSA limits?

As of October 2026. Two different IRS releases set these: the section 223 revenue procedure lands in the spring, the section 125 figures in the autumn, so this page is revised twice a year.

The HSA limits count everything that goes in, including anything your employer puts there. The dependent-care figure is the one that moved most: it had been $5,000 since the 1980s and rose to $7,500 for 2026.

Who is allowed to contribute to an HSA at all?

Eligibility is a test you pass each month, not a status you keep. On the first day of a month you must be covered by a qualifying high-deductible health plan and have no other health coverage, with narrow exceptions.

Four things disqualify you: other health coverage that is not an HDHP, including a general-purpose health FSA; being enrolled in Medicare; being claimed as someone else's dependent; and certain veterans' benefits received recently. The first of those is the one nobody checks, because it does not have to be your coverage.

Can you have an FSA and an HSA at the same time?

Not a general-purpose one. A health FSA pays general medical expenses, which makes it other health coverage, and other health coverage ends HSA eligibility.

The part that surprises people is that it reaches across a household. A general-purpose health FSA covers the employee's spouse and tax dependents by default. So your spouse's election is disqualifying coverage for you, even if you are on a different health plan, never enrol in their FSA and never submit a claim to it. Nothing tells you this has happened. Your HR portal knows your elections, not your spouse's employer's plan design.

May that person contribute to an HSA? Assumes the person is otherwise eligible and enrolled in a qualifying HDHP. A dash means the question does not arise for that person in that configuration.

Read the fourth column before the first two. In the row that catches most households, the answer was decided by someone who is not the account holder and may not be the person reading this. The document that settles it is the other plan's summary plan description, and you are entitled to ask for it.

What is a limited-purpose FSA, and does it fix this?

Yes, and it is the only clean fix. A limited-purpose FSA may only reimburse dental and vision costs, and sometimes preventive care. Because it does not pay general medical expenses, it is not disqualifying coverage, so both accounts can run at once.

Two practical notes. The employer has to offer it: this is a plan design choice, not something an employee can elect unilaterally. And when it is the spouse's FSA causing the problem, it is their plan that has to offer the limited-purpose version, which means the conversation is with their HR department, during their enrolment window.

Does last year's FSA still block you in January?

Often, yes. Two features carry a general-purpose FSA into the new plan year, and the disqualification travels with the balance.

• A carryover of up to $680 moves unused money into the next year. While that balance sits in a general-purpose FSA, it is still coverage, and you are still ineligible.
• A grace period gives about 2.5 months after the plan year ends to spend the old balance. Those months are disqualifying too.

A plan may not have both. The usual fix is to arrange, before the year begins, for the carryover to land in a limited-purpose FSA instead, which many plans allow. Spending the balance to zero before year end also works. Discovering the problem in February does not, because the months have already gone.

Where does a dependent-care FSA sit in all this?

Outside it. A dependent-care FSA reimburses childcare and similar costs, not medical ones, so it is not health coverage and it has no effect on HSA eligibility at all. You can hold one alongside an HSA with no interaction.

Its limit of $7,500 is per household rather than per person, so two spouses cannot each elect the full amount, and it is capped at the lower of the two spouses' earned income.

What happens if you contribute when you weren't eligible?

It is fixable, and the deadline is the thing that matters. Withdraw the excess plus the earnings attributable to it by the due date of your return, including extensions, and the excess is not penalised; the earnings come back as taxable income for the year.

Leave it there and it attracts a 6% excise tax on Form 5329, charged again for every year it remains. If the money went in through payroll it also escaped income tax and FICA it should not have, so the correction runs through your employer where the year is still open. Form 8889 is where HSA contributions and eligibility are reported, and mid-year changes in coverage are prorated month by month on it.

Which account should you actually be in?

For most people this is not a choice. Your employer's plan menu decides which accounts exist, and the health plan decides whether an HSA is even possible. Choose the health plan on what your family's medical costs are likely to be, not on the tax treatment: the deductible exposure is the larger number by far.

Where you do have a choice, the tax arithmetic is worth seeing, because contributions made through payroll escape FICA as well as income tax, which a 401(k) deferral does not:

That FICA saving is the quiet advantage over a retirement account: $4,400 into an HSA by payroll saves $1,305 where the same amount deferred into a 401(k) saves $968, because Social Security and Medicare are charged on a 401(k) deferral and not on a cafeteria plan contribution. An HSA deduction is also available whether or not you itemise, unlike most of what competes with the standard deduction, and the marginal rate it is worth comes from the federal brackets.

One state caveat worth knowing: California and New Jersey do not follow the federal treatment, so HSA contributions are added back on the state return and California taxes the earnings as they arise. Both states see regular bills to change that, so check the current position; your state's rate is on its income tax calculator page.

The eligibility rules here are a coverage test, which is a different mechanism from the income phase-out that governs a Roth IRA: that limit falls gradually with income, this one goes to zero the moment the wrong coverage exists.
