COBRA reimbursement is money returned to you for continuation coverage premiums you already paid, and it usually reaches you through one of three routes: a severance agreement in which your former employer covers premiums for a set number of months, a health reimbursement arrangement funded by an employer, or a refund from the plan administrator when you overpaid or canceled mid-cycle. Because COBRA lets a plan charge up to 102% of the full premium the plan would otherwise pay to cover you,1Office of the Law Revision Counsel. 29 USC 1162 – Continuation Coverage getting that money back can be the difference between keeping the coverage and dropping it. The tax treatment of the reimbursement is a separate question, and it turns almost entirely on how your original premiums were funded.
Reimbursement Through a Severance Agreement
The most common path starts at separation. An employer agrees, as part of a severance package, to reimburse your COBRA premiums for a fixed period, often three to six months. The written agreement should say how long the reimbursement lasts, whether you submit receipts for repayment or the employer pays the insurer directly, and any conditions you must satisfy, such as signing a release of claims.
When the reimbursement is part of a broader severance plan, it generally falls under the Employee Retirement Income Security Act, which makes the employer’s promise enforceable and subject to ERISA’s claims procedures.2U.S. Department of Labor. Advisory Opinion 1992-03A If the employer fails to honor the commitment, you use the plan’s internal claims process first, and can escalate to the Department of Labor or to court after that. ERISA generally limits your remedies to the benefits the plan promised, so punitive damages are not on the table. That makes documentation your real leverage: keep every premium receipt, bank statement, and email confirming the reimbursement terms.
Reimbursement Through a Health Reimbursement Arrangement
Some employers reimburse COBRA costs through formal HRA structures instead of a straight severance payment. These arrangements carry tax advantages when they are set up correctly.
Qualified Small Employer HRAs
A small employer that does not offer a group health plan can use a Qualified Small Employer HRA to reimburse employees for health insurance premiums, including COBRA premiums, up to annual IRS limits. For 2026, those limits are $6,450 for self-only coverage and $13,100 for family coverage.3Internal Revenue Service. Revenue Procedure 2025-32 You have to show proof of actual health coverage to receive the reimbursement.4Office of the Law Revision Counsel. 26 USC 9831 – General Exceptions
Individual Coverage HRAs
Larger employers sometimes use an Individual Coverage HRA to reimburse former employees for premiums during a COBRA continuation period. With an ICHRA, the HRA itself can be the COBRA-eligible benefit. If you elect COBRA continuation of your ICHRA, the employer keeps funding the monthly allowance and you pay a premium (up to 102% of the cost) to keep it active. You then use the HRA dollars to reimburse yourself for an individual policy you buy on your own. You cannot receive standard ICHRA reimbursements and separate COBRA coverage at the same time for the same expenses.
Traditional HRAs
A traditional HRA attached to a group health plan works similarly. If the HRA was part of your benefits before separation, you can elect COBRA continuation of the HRA and draw down remaining funds for eligible medical expenses during the continuation period.
How the IRS Taxes a COBRA Reimbursement
The tax outcome depends on how you originally paid the premium and how the reimbursement is structured.
After-Tax Premiums Reimbursed by an Employer
If you paid COBRA premiums with after-tax dollars and your employer reimburses you under an accident and health plan, the reimbursement is generally excluded from your gross income under IRC Section 105(b), which excludes amounts paid to reimburse you for medical care, including health insurance premiums.5Office of the Law Revision Counsel. 26 USC 105 – Amounts Received Under Accident and Health Plans Revenue Ruling 2002-3 reinforces this treatment, confirming that employer reimbursements for premiums an employee actually paid are excludable under IRC Section 106.6Internal Revenue Service. Revenue Ruling 2002-3
Pre-Tax Premiums Are the Trap
The analysis flips if your original workplace premiums were deducted pre-tax through a Section 125 cafeteria plan. Reimbursing premiums that were never in your income to begin with does not qualify for the Section 105(b) or 106 exclusion, and those reimbursements are treated as taxable wages subject to income and FICA withholding. People routinely assume every COBRA reimbursement is tax-free. Whether your workplace premiums were pre-tax or after-tax is the single biggest variable in your tax bill on the reimbursement.
Direct Payment Versus Lump Sum
When an employer pays the COBRA premium directly to the insurance carrier on your behalf, the value of that benefit is generally tax-free to you. A lump sum handed to you without being tied to premium payments under a qualifying plan arrangement can be treated as taxable severance pay instead. Any amount that exceeds your actual COBRA costs is taxable income no matter how the arrangement is labeled. Keep the reimbursement tightly linked to documented premium payments, and make sure the severance agreement identifies the payment as being for health coverage rather than general compensation.
Paying COBRA With an HSA
Health Savings Account funds can pay for COBRA premiums. This is one of the narrow exceptions to the general rule that HSA money cannot cover insurance premiums; IRS Publication 969 specifically lists health care continuation coverage such as COBRA as an eligible HSA expense.7Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans The withdrawal is tax-free provided you use it for the premium and the same premium is not reimbursed from another source.
That last piece matters. The IRS prohibits “double dipping,” so you cannot pay a COBRA premium from your HSA and also collect a reimbursement for the same premium from an employer HRA or severance arrangement. If an employer is reimbursing you, pay the premiums out of pocket with ordinary funds. That keeps the employer reimbursement tax-free and leaves your HSA balance available for other medical expenses. Breaking the rule can disqualify the tax-free treatment of the expense and, in serious cases, jeopardize the tax-qualified status of the employer’s HRA plan.8Newfront.

Refunds for Overpayments and Mid-Month Cancellations
Not every reimbursement involves an employer. Some come from ordinary billing errors, most often a duplicate payment when an automated bank draft processes the same month you mailed a check. The plan administrator should reconcile the account and return the overpayment.
If you start a new employer’s health plan and cancel COBRA mid-month after paying that month’s premium, whether you receive a pro-rated refund depends on plan terms. No federal regulation requires a pro-rated refund for a partial month of COBRA coverage. Some plans refund the unused portion; others treat each month as a full billing cycle with no partial credits. Read the plan documents. If a refund is owed and has not shown up within 30 to 45 days, follow up in writing so you have a paper trail if you need to escalate.
Documents to Have Ready
Before submitting any reimbursement request, gather:
- Your COBRA election notice, which identifies the plan, describes the continuation coverage, and lists the plan administrator’s contact information.9eCFR. 29 CFR 2590.606-1 – General Notice of Continuation Coverage
- Proof of each premium payment: cleared bank statements, canceled checks, or credit card statements, matched to specific coverage months.
- The signed severance agreement or HRA plan document that establishes the employer’s commitment.
- The administrator’s reimbursement request form, usually available through an HR portal or benefits packet, showing the coverage period and premium amount.
Keep digital copies of everything so you can resubmit quickly if a paper submission is lost.
Submitting the Request
Follow the delivery instructions your plan administrator or former employer’s HR department provides. Many administrators use secure online portals with instant upload confirmations. If you mail in the request, use certified mail with return receipt to get a verifiable delivery record. Processing usually takes two to eight weeks depending on workload and whether your paperwork is complete. Funds typically arrive by direct deposit or check. If six weeks pass without an update, follow up in writing and reference your submission date and any confirmation numbers.
If Reimbursement Is Denied or Delayed
Start with the plan’s internal claims procedure. ERISA-covered plans have to provide a formal dispute process, and skipping it can get a later lawsuit dismissed for failure to exhaust administrative remedies.
If the internal process does not resolve the issue, contact the Department of Labor’s Employee Benefits Security Administration. EBSA benefits advisors handle ERISA complaints informally, and you should be ready to give your name, a description of the problem, evidence you filed a claim, and the plan administrator’s or employer’s contact information.10U.S. Department of Labor. What We Do EBSA aims to update you every 30 days, but the process is informal and does not include litigation on your behalf.
The statutory penalties give you leverage in negotiations. Under IRC Section 4980B, an employer that fails to comply with COBRA requirements faces an excise tax of $100 per day per affected beneficiary during the noncompliance period, with a minimum penalty of $2,500 if the failure is not corrected before an IRS examination notice and up to $15,000 for violations that are more than minor.11Office of the Law Revision Counsel. 26 USC 4980B – Failure to Satisfy Continuation Coverage Requirements Courts can also impose penalties of up to $110 per day for failures to provide required COBRA notices under ERISA Section 502(c)(1). Pointing to these numbers in a written follow-up often moves a stalled reimbursement.
