Yes. Every Bronze plan sold on HealthCare.gov or a state exchange is a bronze plan HSA eligible 2027 option, and so is every Catastrophic plan. A 2025 federal law made both types count as HSA-compatible starting January 1, 2026, and the rule carries into 2027. If you enroll in one and meet the IRS rules, you can put up to $4,500 (self-only) or $9,000 (family) into a Health Savings Account for 2027, deduct it on your tax return, and spend it tax-free on medical bills.

- All Bronze and Catastrophic plans sold on an exchange count as HSA-compatible high-deductible plans, whatever their deductible.
- 2027 HSA limits are $4,500 for self-only coverage and $9,000 for family coverage. If you're 55 or older you can add $1,000.
- On HealthCare.gov, enroll by December 15, 2026 for coverage starting January 1. Open enrollment ends January 15, 2027.
- You can't contribute if you're on Medicare, can be claimed as someone's dependent, or have other health coverage that isn't an HDHP, such as a spouse's general-purpose FSA.
- Bronze plus an HSA often costs less than Silver for healthy people who get no subsidy. Run the numbers with your own quotes before you choose.
What Changed: Every Bronze and Catastrophic Marketplace Plan Is Now HSA-Eligible (and Still Is in 2027)
Before 2026, a Bronze plan worked with an HSA only if it met the IRS's strict "high deductible health plan" (HDHP) rules. Many Bronze plans didn't, because their out-of-pocket maximums were higher than the HDHP cap.
The One Big Beautiful Bill Act changed that. In IRS Notice 2026-5, the IRS confirmed that Bronze and Catastrophic plans available through an exchange are treated as HDHPs from January 1, 2026, whether or not they meet the usual deductible and out-of-pocket tests.
A few details matter:
- Off-exchange versions count too. If the identical plan is sold through the exchange, buying it directly from the insurer is fine. A Bronze plan sold only off-exchange still has to meet the traditional HDHP rules (CMS).
- Small-business SHOP plans don't count. Bronze coverage bought through an employer's SHOP plan isn't individual coverage, so the new rule doesn't apply (Notice 2026-5).
- The filter is built in. On HealthCare.gov, tick "Eligible for an HSA" to see qualifying plans in your area (HealthCare.gov).
CMS says the change opened HSA-eligible plans to at least 1.6 million more HealthCare.gov consumers. For 2026, 43% of people who picked a plan on the platform chose an HSA-eligible one (CMS 2026 Open Enrollment Report).
New for 2027: the standard out-of-pocket cap for Marketplace plans is $12,000 for self-only coverage (CMS). Under the 2027 Payment Notice, insurers may now offer Bronze plans with out-of-pocket limits up to 130% of that cap, which is $15,600. Insurers don't have to offer these plans, and states can ban them. They're still HSA-eligible, so check each plan's out-of-pocket maximum before you choose it.
2027 HSA Contribution Limits at a Glance ($4,500 Self-Only, $9,000 Family, $1,000 Catch-Up)
The IRS set the 2027 numbers in Rev. Proc. 2026-24. The 2026 figures come from Rev. Proc. 2025-19.
| Item | 2026 | 2027 |
|---|---|---|
| HSA contribution limit, self-only | $4,400 | $4,500 |
| HSA contribution limit, family | $8,750 | $9,000 |
| Catch-up (age 55+) | $1,000 | $1,000 |
| HDHP minimum deductible (self / family) | $1,700 / $3,400 | $1,750 / $3,500 |
| HDHP out-of-pocket max (self / family) | $8,500 / $17,000 | $8,700 / $17,400 |
| Direct primary care fee allowed (1 person / more) | n/a | $150 / $300 per month |
The HDHP deductible and out-of-pocket figures still apply to employer plans and to Bronze plans sold only off-exchange. Exchange Bronze and Catastrophic plans qualify automatically, so those caps don't limit them.
If you're 55 or older and also make retirement catch-up contributions, see our guide to the Roth catch-up rule for 2027. It's a separate rule, but both affect your 2027 tax planning.
Who Qualifies: The HSA Eligibility Rules You Still Have to Meet
The right plan is only half the test. According to IRS Publication 969, you're an eligible individual only if all of these are true:
- You're covered by an HDHP on the first day of the month. Exchange Bronze and Catastrophic plans count.
- You have no other disqualifying health coverage. A spouse's general-purpose health FSA that can pay your bills counts as other coverage. So does a non-HDHP plan through a spouse's job.
- You aren't enrolled in Medicare.
- Nobody can claim you as a dependent on their tax return.
Catastrophic plans have their own entry rules. Before 2026 you generally had to be under 30 or have a hardship exemption. CMS added a hardship exemption for people who don't qualify for premium tax credits because of their income, including those with projected income above 400% of the federal poverty level (CMS). Premium tax credits can't be used on a Catastrophic plan.
2027 Open Enrollment Deadlines: Dec 15 for a Jan 1 Start, Jan 15 Final Date
For states that use HealthCare.gov (CMS key dates):
- November 1, 2026: Open Enrollment starts.
- December 15, 2026: Last day to enroll for coverage starting January 1, 2027.
- January 15, 2027: Open Enrollment ends. If you enroll between December 16 and January 15, coverage starts February 1.
State-run exchanges set their own dates, and some stay open later into January. If your state runs its own exchange, check the deadline on its website rather than relying on the dates above.
One more deadline: you can make 2027 HSA contributions until your tax filing due date in April 2028. Extensions don't count (Pub. 969).
Bronze + HSA vs. Silver Plan: A Real-Dollar Comparison After the Enhanced Subsidies Ended
The extra premium tax credits from 2021–2025 expired at the end of 2025. People earning above 400% of the poverty level get no federal premium help again. For people who enrolled in 2026, average net premium payments rose 58%, from $113 to $178 a month (KFF). If you're paying full price, the gap between Bronze and Silver premiums matters more than it did.
Example: Maria is a 40-year-old freelance designer in Texas. Her income is too high for a premium tax credit. The premiums and deductibles below are placeholder numbers to show the math. They aren't actual 2027 Texas rates, which you should pull from HealthCare.gov for your ZIP code.
| Illustrative numbers | Bronze + HSA | Silver (no HSA) |
|---|---|---|
| Annual premium | $4,800 ($400/mo) | $6,240 ($520/mo) |
| Out-of-pocket maximum | $10,000 | $9,000 |
| HSA contribution | $4,500 | $0 |
| Federal tax saved (22% bracket) | $990 | $0 |
| Net cost, light year ($500 of care) | $4,310 | $6,740 |
| Net cost, worst case (hits out-of-pocket max) | $13,810 | $15,240 |
Here's the math. In a light year, Bronze costs $4,800 + $500 − $990 = $4,310. Silver costs $6,240 + $500 = $6,740. In a bad year, Bronze costs $4,800 + $10,000 − $990 = $13,810, and Silver costs $6,240 + $9,000 = $15,240. The $4,500 Maria puts in the HSA isn't counted as a cost because it stays her money.
The quick test: compare (Silver premium − Bronze premium + your HSA tax savings) with (Bronze out-of-pocket max − Silver out-of-pocket max). If the first number is bigger, Bronze wins even in a worst-case year.
There's one big exception. If your income qualifies you for cost-sharing reductions, which come only with Silver plans, Silver's deductibles can drop sharply and may beat Bronze. Also, many Silver plans cover some visits with a copay before you meet the deductible, which helps if you use a lot of care.
The Triple Tax Advantage Explained: Deduction, Tax-Free Growth and Tax-Free Medical Withdrawals
- Deduction going in. Contributions you make yourself are deducted on your return through Form 8889, even if you don't itemize. At the 22% bracket, Maria's $4,500 cuts her federal income tax by $990. CMS also notes that HSA contributions can lower the income the Marketplace uses for subsidies (CMS FAQ). That can help if you're close to the 400% cliff.
- Tax-free growth. Interest and investment gains inside the HSA aren't taxed while they stay in the account (Pub. 969).
- Tax-free withdrawals for qualified medical expenses. If you use the money for anything else, it's taxable income plus a 20% additional tax. That extra tax doesn't apply after age 65, at disability, or at death (Form 8889 instructions).
For self-employed people there's one more rule: your HSA contribution can't exceed your net self-employment income (Pub. 969).
How to Open and Fund an HSA Once You Enroll in a Bronze Plan
- Pick your plan on HealthCare.gov or your state exchange using the "Eligible for an HSA" filter, and pay your first premium.
- Choose an HSA custodian. Banks, credit unions and brokerages offer HSAs. You don't need your insurer's partner.
- Compare the details: monthly fees, the cash balance required before you can invest, investment choices and their costs, a debit card, and an easy way to save receipts.
- Open the account after your coverage starts. Expenses from before you set up the HSA can't be reimbursed from it (Pub. 969).
- Fund it with a lump sum or monthly transfers. Mark each deposit as being for the correct tax year, especially deposits made January through April.
- File Form 8889 with your 2027 return.
Mid-Year Enrollment, the Last-Month Rule and the Testing Period
Normally your limit is prorated by month. Say you enroll January 10 and your Bronze plan starts February 1, 2027. That's 11 eligible months, so your self-only limit is $4,500 × 11/12 = $4,125.
The last-month rule is an alternative. If you're eligible on December 1, 2027, you can contribute the full-year amount. The catch is that you then have to stay eligible through the testing period, which runs from December 1, 2027 through December 31, 2028. If you lose eligibility for a reason other than death or disability, the extra amount you contributed because of the rule becomes taxable income, plus a 10% additional tax (Pub. 969).
If you might switch to a job with a non-HDHP plan in 2028, the prorated limit is the safer choice.
6 Common Mistakes Marketplace Buyers Make With HSAs
- Over-contributing. Any excess left in the account is hit with a 6% excise tax every year it stays there. You can avoid that by withdrawing the excess and its earnings by your return's due date, including extensions (Form 5329 instructions).
- Ignoring a spouse's FSA. A general-purpose health FSA through your spouse's job can disqualify you (Pub. 969).
- Missing the Medicare overlap. Premium-free Part A can start up to six months before the date you apply. SSA advises stopping HSA contributions at least six months before you apply for Medicare (SSA, Medicare.gov).
- Skipping Form 8889. You need it to claim the deduction and to report any withdrawals.
- Paying premiums from the HSA. Marketplace premiums generally aren't qualified expenses (HealthCare.gov).
- Leaving the account underfunded. A Bronze plan only works if you can cover the deductible. An emergency fund helps, especially if you're also paying down debt. Our 7-step debt plan covers that. If you've been putting off coverage, read why waiting on insurance can cost thousands.
Frequently Asked Questions
Is every Bronze plan HSA-eligible in 2027?
Every Bronze plan available through an exchange is, along with identical versions sold off-exchange. Bronze plans sold only off-exchange still have to meet the regular IRS HDHP rules, and small-employer SHOP Bronze plans don't qualify.
Can I open an HSA with a Catastrophic plan?
Yes. Exchange Catastrophic plans are treated as HDHPs from 2026 on. You still have to meet the Catastrophic entry rules: under 30, or holding a hardship exemption. Premium tax credits can't be applied to these plans.
What is the 2027 HSA contribution limit?
$4,500 for self-only coverage and $9,000 for family coverage, plus $1,000 if you're 55 or older, per IRS Rev. Proc. 2026-24.
What is the deadline to enroll for January 1, 2027 coverage?
December 15, 2026 on HealthCare.gov. Open Enrollment closes January 15, 2027, and enrollments after December 15 start February 1. State exchanges may have different dates.
Is Bronze plus an HSA cheaper than Silver?
Often, if you're healthy and get no subsidy, because you pay lower premiums and get a tax deduction. If you qualify for cost-sharing reductions or expect heavy medical use, Silver can come out ahead. Compare total yearly cost with your actual quotes.
When can I make my 2027 HSA contributions?
Any time from January 1, 2027 until your tax filing due date in April 2028. Extensions don't extend it.
Can I keep contributing to my HSA after I enroll in Medicare?
No. Once you're enrolled in Medicare you can't contribute. Because Part A can be backdated up to six months, stop contributing about six months before you apply.
