HSA-eligible marketplace plans for early retirees

By Tom, CPA · Updated October 25, 2026

TL;DR: For 2026, HSA limits are $4,400 self-only and $8,750 family. New law makes all bronze and catastrophic marketplace plans HSA-compatible starting January 1, 2026. HSA contributions also lower MAGI, which can raise your premium tax credit.

The triple-tax-advantaged account, now with more bronze. For years the health savings account was a perk tied to a narrow category of high-deductible plans. Early retirees shopping the marketplace often found few qualifying options. As of 2026 that changed: the IRS says that, starting January 1, 2026, bronze and catastrophic plans available through an exchange are treated as HSA-compatible, whether or not they would otherwise meet the high-deductible health plan definition.

This guide covers what's HSA-eligible now, the 2026 limits, how contributions interact with your subsidy, and the Medicare trap waiting at 65.

CPA Warning Label: An HSA is the only account that's tax-free going in, growing and coming out for medical bills. Treating it like a checking account for Band-Aids is allowed, but it hurts a little to watch.

What qualifies as an HDHP

Traditionally, an HSA requires coverage under a high-deductible health plan (HDHP) and no other disqualifying coverage. For 2026, Revenue Procedure 2025-19 sets the HDHP minimum deductible at $1,700 for self-only coverage and $3,400 for family coverage, and caps out-of-pocket expenses at $8,500 and $17,000.

The One Big Beautiful Bill Act, which the IRS calls the Working Families Tax Cuts legislation, added several expansions effective for 2026:

• Bronze and catastrophic exchange plans are treated as HSA-compatible starting January 1, 2026.
• Direct primary care arrangements that meet certain requirements no longer disqualify you from contributing, and fees can be paid from an HSA.
• Telehealth: the safe harbor allowing plans to cover telehealth before the deductible was made permanent.

Silver and gold plans still need to meet the HDHP rules to qualify. Plan listings on HealthCare.gov flag HSA-eligible plans; confirm in the plan documents.

2026 contribution limits

The $1,000 catch-up is set by statute and is not inflation-adjusted. Each spouse who is 55 or older needs their own HSA to make their own catch-up. Contributions are generally prorated by the months you're eligible, with a "last-month rule" that can allow a full-year contribution if you're eligible on December 1 and stay eligible through the following year.

Retirees can contribute without earned income. Unlike an IRA, HSA eligibility depends on coverage, not wages.

HSA vs premium tax credit interaction

HSA contributions you make yourself are an above-the-line deduction, so they reduce AGI and therefore ACA MAGI. That lowers your required contribution toward the benchmark plan and raises your credit.

Illustration: a couple, both 58, on a family bronze plan with 2026 MAGI of $60,000 before HSA contributions. They contribute $8,750 plus two $1,000 catch-ups, $10,750 in total. MAGI falls to $49,250.

• At $60,000 (about 283.7% of FPL) their applicable percentage is about 9.46%, an expected contribution of about $5,678.
• At $49,250 (about 232.9% of FPL) it's about 7.81%, an expected contribution of about $3,846.

The credit rises by about $1,832. Add federal income tax saved on $10,750 (about $1,290 in the 12% bracket) and the HSA delivers roughly $3,100 of value in one year, before any growth. Near the 400% line the effect can be even larger: an HSA contribution can pull a household back under the cliff.

Medicare cutoff

Once you're enrolled in any part of Medicare, you can't contribute to an HSA. The trap: Medicare.gov says that if you sign up for Part A after you turn 65, your Part A coverage can be retroactive up to six months, though not before the month you turned 65. Contributions during those retroactive months become excess contributions.

Also, claiming Social Security after 65 automatically enrolls you in Part A. If you're planning HSA contributions around 65, stop contributions about six months before you apply for Medicare or Social Security. See the Medicare enrollment timeline.

Already-saved HSA money stays yours. After 65 you can pay Medicare Part B, Part D and Medicare Advantage premiums from the HSA tax-free (not Medigap premiums), plus qualified expenses. Non-medical withdrawals after 65 are taxed as income but no longer carry the 20% penalty.

Shopping strategy

1. Compare total cost, not just premiums. Bronze premiums are lower, but deductibles are high. Add expected out-of-pocket costs and the HSA tax savings.
2. Remember cost-sharing reductions. If your income is low enough for silver plan cost-sharing reductions, a silver plan with much lower deductibles may beat bronze plus HSA. See ACA cost-sharing reductions.
3. Check the benchmark gap. Your credit is based on the second-lowest silver plan. If the credit exceeds a bronze premium, the bronze plan may cost almost nothing; the excess credit isn't refunded.
4. Keep receipts. HSA reimbursements have no deadline as long as the expense occurred after the HSA was established. Some savers pay out of pocket now and reimburse themselves years later.
5. Watch disqualifying coverage. A spouse's general-purpose health FSA or non-HDHP coverage can make you ineligible.

Catastrophic plans

Catastrophic plans are available to people under 30 or with a hardship or affordability exemption. They now count as HSA-compatible as well. The premium tax credit can't be used for a catastrophic plan, so for subsidized early retirees, bronze is usually the HSA-compatible choice.

Illustration: bronze plus HSA versus silver

Illustration: Lee, 59, single, MAGI $45,000. Assume the benchmark silver plan costs $9,000 a year and the cheapest bronze plan costs $6,600. Under the 2026 table his expected contribution is about $4,312, so his credit is about $4,688.

• Silver: $9,000 minus $4,688 is about $4,312 a year in premiums, with a moderate deductible.
• Bronze: $6,600 minus $4,688 is about $1,912 a year, with a high deductible, but HSA-eligible.

If Lee contributes $5,400 (the $4,400 limit plus the $1,000 catch-up), his MAGI drops to $39,600, which raises his credit further, and he saves federal income tax. If he's healthy, bronze plus HSA likely wins by thousands. If he expects heavy use, the silver plan's lower cost-sharing may close the gap. Run both with realistic medical spending, including a bad year at the out-of-pocket maximum.

Investing the HSA

Many HSA custodians allow investing in index funds once a minimum cash balance is held. For early retirees with other liquid savings, treating the HSA as a long-term account and paying current medical bills from cash can maximize tax-free growth. Keep a digital folder of receipts; you can reimburse yourself later, in a year when you need cash and want to avoid adding MAGI.

That last point is a quiet MAGI tool: an HSA reimbursement of old receipts is tax-free cash that doesn't show up as income, which helps near the ACA cliff and, after 65, near IRMAA tiers. See Part B premiums and IRMAA.

Common mistakes

• Contributing for months you weren't covered by a qualifying plan.
• Forgetting to reduce contributions when switching mid-year from an HSA-eligible plan to one that isn't.
• Funding an HSA during retroactive Medicare months.
• Not reporting HSA contributions when estimating MAGI for the marketplace, which overstates income and understates the credit you receive in advance.

Year-by-year HSA plan before 65

Think of the HSA years as a window that closes at Medicare. From retirement to roughly 64 and a half, every year on an HSA-compatible plan is a chance to contribute the full limit, including the catch-up after 55, lower MAGI, and invest for later medical costs. Couples where both are over 55 should open two accounts so both catch-ups count. In the last year, prorate by months of eligibility and stop contributing about six months before Medicare enrollment if you'll apply after 65. After that, the account shifts from saving to spending, ideally on Medicare premiums and the medical bills that tend to arrive later in retirement.
