Company-Paid COBRA Severance: Agreement Terms, Medicare, and Limits

Company-paid COBRA in a severance package means your former employer covers some or all of your COBRA continuation premiums for a defined period after your job ends, typically three to six months. You keep your existing health plan and provider network, the company pays the carrier, and you avoid what would otherwise be a monthly premium of several hundred to well over a thousand dollars. The benefit is real, but it depends on electing COBRA on time, getting the payment structure right for tax purposes, and planning for the day the subsidy stops.

How the Subsidy Is Structured and Why It Matters for Taxes

Employers pay severance COBRA in one of three ways, and the choice drives your tax bill more than the headline dollar amount does.

The cleanest arrangement is direct payment. The company pays the insurance carrier or third-party COBRA administrator on your behalf, and you never see a bill for the covered months. Under 26 U.S.C. § 106, employer-provided coverage under an accident or health plan is generally not treated as taxable wages, so direct-paid COBRA premiums typically do not appear as taxable income on your W-2.¹

The second structure is reimbursement. You pay the full COBRA premium each month and submit proof to HR for a refund. That creates cash-flow pressure and reimbursement delays. The tax treatment sits in a gray area: if the employer runs reimbursements through a formal health reimbursement arrangement, the amounts may be excludable; if HR simply cuts you a check after seeing a receipt, the IRS is more likely to treat the money as taxable compensation. Ask how the company plans to report the payments before you sign.

The third structure is a lump-sum cash payment added to your severance or final paycheck, meant to cover several months of premiums. The IRS treats that money as supplemental wages subject to a flat 22% federal withholding rate.² State income tax and FICA come off the top as well. A $6,000 lump sum intended to buy six months of coverage can leave you well short of what the COBRA administrator actually bills. If you have any leverage in the negotiation, ask for direct carrier payment instead of cash.

You Still Have to Elect COBRA on Time

Company-paid COBRA does not activate automatically. Even if your severance agreement guarantees six months of paid premiums, you have to formally elect COBRA within the required window or you lose the benefit permanently.

After your last day, the plan administrator sends an election notice. You then have 60 days from the notice or the loss of coverage (whichever is later) to elect.³ Miss it and the right to continue your group plan is gone, severance promises notwithstanding.

The election notice lists the monthly premium by tier: individual, employee-plus-spouse, or family. The maximum a plan can charge is 102% of the applicable premium, meaning the base cost plus a 2% administrative surcharge.⁴ Identify the exact figure for your tier and share it with HR so the subsidy is calculated correctly.

After you elect, the first premium is due within 45 days. Later months carry a 30-day grace period after each due date.⁵ When the employer pays the carrier directly, those deadlines belong to the company. Under a reimbursement model, they belong to you.

What to Pin Down in the Written Agreement

A verbal promise from HR to “take care of the COBRA” is worth nothing if the contact leaves or the company reverses course. Every material term goes in the severance document.

Duration. Three to six months is common, but the federal COBRA maximum for a job loss is 18 months, so anything up to that is on the table.⁶
Percentage of the premium. Push for 100%, including the 2% administrative fee. Some agreements only cover the portion the employer used to pay, leaving you with what came out of your paycheck.
Payment method. Direct payment to the carrier beats a taxable lump sum, sometimes by hundreds of dollars after tax.
Early termination language. Most agreements end the subsidy when you become eligible for another employer’s group plan. Ask for “eligible for” to read as “enrolled in” so a probationary waiting period at a new job does not cut off your bridge coverage.
Dependents. Confirm the subsidy covers the same tier you had as an employee, and that spouses and dependent children are listed as qualified beneficiaries on the election form.

When the Subsidy Runs Out

The 18-month federal COBRA clock runs from the qualifying event, not from the day the employer stops paying. If the company covered six months, you have 12 months left at full price. The administrator normally sends notice before the employer portion expires, with the new payment amount and instructions. You get the same 30-day grace period on each future payment; miss it and coverage cancels with no reinstatement.⁵

Here is the trap most people miss: the end of your employer’s subsidy is not a special enrollment event for the ACA Marketplace or another group plan.⁵ Losing your job did open a 60-day Marketplace enrollment window, and that window runs whether or not you elect COBRA.⁷ Once it closes, voluntarily dropping COBRA before it runs out its full 18 months does not reopen it. You would have to wait for Open Enrollment or a separate qualifying life event.⁸

The practical move: within the first 60 days after your job ends, price Marketplace plans and compare them, with any premium tax credits you qualify for, against the full COBRA premium you will owe after the subsidy stops. If the Marketplace is comparable or cheaper, enroll during that initial window rather than banking on the employer-paid months alone.

If you have money in a Health Savings Account, you can use it to pay COBRA premiums tax-free. IRS Publication 969 lists health care continuation coverage under Section 4980B as a qualifying HSA expense.⁹ That is one of the few times HSA funds can pay insurance premiums without a tax hit, and it can bridge the months between the employer subsidy and your next plan.

If You Are Near 65, Medicare Changes the Math

COBRA does not count as coverage through “current employment” for delaying Medicare enrollment. Your 8-month Medicare special enrollment period starts when you stop working or lose employer coverage, whichever comes first, regardless of whether you elect COBRA.¹⁰

Miss that window and two things happen. You cannot enroll in Part B until the next General Enrollment Period (January through March), with coverage starting in July, and you owe a lifetime Part B late enrollment penalty of 10% for every full 12-month period you were eligible but not enrolled.¹⁰

There is a coordination problem too. If you are Medicare-eligible but stay on COBRA without enrolling in Medicare, the COBRA plan can treat Medicare as the primary payer even though you have not signed up, leaving you responsible for the balance on claims. Employer-paid COBRA is generous, but for anyone around 65, enrolling in Medicare Parts A and B on time is not optional.

Two Boundaries to Know

Federal COBRA only applies to employers that had 20 or more employees on a typical business day during the prior calendar year.¹¹ If your former employer was smaller, federal COBRA does not apply no matter what the severance agreement says. Many states have their own continuation coverage laws (sometimes called mini-COBRA) for smaller employers, with durations that vary by state. Check your state insurance department.

Even at larger employers, the statute excludes terminations “by reason of such employee’s gross misconduct” from qualifying events.¹² Federal law does not define the term precisely. An employer’s willingness to include paid COBRA in a severance package is a strong signal it is not characterizing your departure that way, but read the agreement for any conflicting language about the reason for termination.

If the Employer Stops Paying

A severance agreement is a contract. A company that promised to pay your COBRA premiums and then stops has breached it. The first sign is usually a bill from the administrator or a lapse notice. Move fast, because the 30-day grace period runs regardless of whose fault the missed payment is.

Contact HR in writing. Email creates the paper trail you will need later. Cite the specific section of the severance agreement, and ask for written confirmation the payment will go through before the grace period ends.

Most employer severance arrangements fall under ERISA, and ERISA generally requires you to run any claim through the plan’s internal claims procedure before suing. Courts routinely dismiss cases where the employee skipped that step, and later judicial review is usually limited to the record you built during the internal process. Document thoroughly from the start.

While the dispute plays out, protect the coverage. If you can afford to pay the premium out of pocket to keep the plan active, do it and keep every receipt. Retroactive reinstatement after a lapse is not guaranteed, and going without coverage while you wait for the employer to fix the problem is a serious risk. Those receipts become the basis for a reimbursement or damages claim.
