Can You Use Your HSA for COBRA Premiums?

Yes, you can use an HSA to pay COBRA premiums, and the payment comes out tax-free. Federal tax law names health care continuation coverage as one of the narrow exceptions to the general rule that HSA funds cannot pay insurance premiums.¹ This applies to money already in your account regardless of whether your COBRA plan is a high-deductible health plan. The harder question, and the one that trips people up, is whether you can keep adding new money to the HSA while enrolled in COBRA.

Why COBRA Premiums Qualify

The default rule for HSAs is that premiums are not a qualified medical expense. COBRA is a listed exception under 26 U.S.C. § 223(d)(2)(C), and the IRS restates this in Publication 969, which permits withdrawals for “health care continuation coverage (such as coverage under COBRA).”²

The exception reaches your spouse and tax dependents too. If your spouse or child has their own COBRA coverage after a qualifying event, your HSA can pay those premiums as long as the person qualifies as your spouse or dependent for tax purposes.

The 2% administrative surcharge that COBRA administrators tack onto the plan premium is part of the premium for HSA purposes. You can pay the full 102% bill from the account. If you qualify for an extended COBRA period due to a disability determination, the surcharge rises to 50% after the 18th month, and that 150% total is also payable from the HSA.³

How to Pay

You have two options. Pay the COBRA administrator directly using the debit card or checks issued by your HSA custodian, or pay the premium out of pocket and reimburse yourself from the HSA later. Both are tax-free.

The reimbursement route has no deadline. The IRS does not require you to pull HSA funds in the same year an expense was incurred, or even the same decade. Some people deliberately pay COBRA out of pocket, let the HSA balance keep growing tax-free, and reimburse themselves years later. The rules are that the expense had to be incurred after the HSA was established and that you keep documentation.

The Establishment-Date Trap

An expense only qualifies if it was incurred after your HSA existed.² COBRA elections apply retroactively to the day after your employer coverage ended, and you have 60 days from the election notice to decide. If you open an HSA after losing coverage but before making the COBRA election, premiums covering the retroactive gap before the HSA existed will not qualify. If the HSA was already open when you lost coverage, this issue does not arise.

Can You Still Contribute While on COBRA?

Spending existing HSA money on COBRA is easy. Putting new money in is the complicated part. To contribute, you must be an “eligible individual,” which means you’re enrolled in a qualifying high-deductible health plan on the first day of the month, have no other disqualifying coverage, and aren’t enrolled in Medicare.²

Whether your COBRA plan is an HDHP depends on the plan itself. COBRA simply continues whatever coverage you had at work. If that plan met the HDHP thresholds before, it still does under COBRA. If it didn’t, you lose contribution eligibility the moment COBRA coverage begins. Contributions made while enrolled in a non-HDHP COBRA plan are excess contributions, subject to income tax plus a 6% excise tax for every year they stay in the account.²

Prorating When Eligibility Changes Mid-Year

If you were HSA-eligible for part of the year and then moved to non-HDHP COBRA coverage, your annual contribution limit is prorated. You get 1/12 of the annual limit for each month you were enrolled in an HDHP on the first day of that month.

The “last month rule” is a workaround. If you are HSA-eligible on December 1 of the tax year, you can contribute the full annual amount as if you were eligible all year. The condition is a 13-month testing period: you must stay enrolled in an HDHP through December 31 of the following year. Fail the test and the excess gets added back to your income along with a 10% additional tax.²

A 2026 Change That May Reshape the Decision

Starting January 1, 2026, bronze and catastrophic marketplace plans are treated as HSA-compatible regardless of whether they meet the standard HDHP deductible and out-of-pocket thresholds.⁴ For someone choosing between COBRA and marketplace coverage, this changes the math. A bronze or catastrophic plan now lets you keep contributing to the HSA even if the plan wouldn’t have qualified under the old rules, which may make it more attractive than COBRA depending on premiums and subsidy eligibility.

A Related Exception Worth Knowing

If you’re on COBRA and collecting unemployment at the same time, a separate premium exception opens up. While you’re receiving unemployment compensation, premiums for any health plan qualify for tax-free HSA payment, not just COBRA continuation coverage.² That gives you more flexibility if you decide to leave COBRA for a marketplace plan while unemployment benefits are still running.

Two other premium categories qualify but sit outside the COBRA situation: qualified long-term care insurance up to age-based annual limits, and Medicare premiums (Parts A, B, C, and D) once you turn 65. Medigap and other Medicare supplemental policies do not qualify.¹

Reporting and Records

Your HSA custodian will send Form 1099-SA reporting every distribution.⁵ You then file Form 8889 with your tax return to report distributions and contributions, and it’s on this form that you identify distributions as going toward qualified expenses.⁶ You must file Form 8889 even if you otherwise have no filing requirement.

The IRS does not ask for proof at filing. It can ask later, and the burden of proof is entirely yours. Keep COBRA invoices, payment confirmations, and the COBRA election notice showing coverage dates. If you reimburse yourself from the HSA rather than paying directly, keep records of the out-of-pocket payment alongside the reimbursement. Because there’s no deadline for taking reimbursements, there’s effectively no expiration on the recordkeeping obligation.

Fixing a Mistaken Withdrawal

If you withdraw HSA funds for something you thought was qualified and later discover it wasn’t, you can return the money to the account. The repayment must happen by the due date of your tax return (without extensions) for the year you discovered the mistake, and a timely repayment avoids both income tax and the 20% additional tax.⁵ Custodians are not required to accept the repayment, so confirm your custodian’s policy before relying on this fix.

Penalties to Avoid

A withdrawal used for something that isn’t a qualified expense gets added to your taxable income for the year, plus a 20% additional tax on the non-qualified amount.¹ The 20% add-on disappears once you turn 65, and also if you become disabled or the distribution follows the account holder’s death, though ordinary income tax still applies.

For COBRA premiums, the risk of accidentally taking a non-qualified withdrawal is low if you keep documentation. The trap that catches more people is excess contributions from continuing to fund the HSA after switching to a non-HDHP COBRA plan. That 6% excise tax compounds every year the excess remains, so catching the mistake fast matters.
