COBRA and Your Health FSA: The Rule Nobody Explains

Start here: which FSA do you have?

This matters more than anything else on the page, because the two accounts people call "my FSA" follow completely different rules.

If yours is a dependent care FSA, skip to the dependent care section. Everything between here and there is about health FSAs only.

Why a health FSA gets COBRA at all

COBRA applies to group health plans. The regulation is explicit that running a benefit through a cafeteria plan does not change that: health care is provided under a plan "whether provided directly or through insurance, reimbursement, or otherwise", and specifically including "through a cafeteria plan (as defined in section 125) or other flexible benefit arrangement".

So the account with your money in it is, legally, a health plan you were covered by, and losing your job is a qualifying event for it just as it is for your medical coverage. That is the good news. The rest of this page is about how much smaller that right is than it first sounds.

One consequence worth knowing immediately: a health FSA is normally administered as its own plan, so you usually elect it separately from your medical coverage and turning one down does not turn down the other. That is not guaranteed, though. Whether benefits count as one plan or several for COBRA purposes depends on what the governing documents say and how they are actually run, which is the same test that decides whether you can keep dental without medical. Your election notice, which has to state a price for each plan on offer, is the quickest way to see how yours is structured.

The two conditions that shrink the obligation

Almost every article on this subject states flatly that FSA continuation ends when the plan year ends. That is usually right, but it is a conclusion, not a rule, and it only holds when two conditions are both satisfied:

1. The FSA is an excepted benefit. That requires your employer to make other group health coverage available to your class of employees, and requires the FSA to be structured so the maximum it can pay out is no more than twice your own salary reduction for the year (or, if greater, your salary reduction plus $500).
2. The maximum annual COBRA premium is at least the maximum annual benefit. In other words, continuing the account for a full year cannot cost less than the account can pay out.

If either condition fails, the shortened treatment does not apply and ordinary COBRA rules do, which means 18 months and across plan years. The realistic way this happens is a large employer flex credit that pushes the maximum benefit above twice what you elected. If your employer put substantial money into your FSA on top of your own contributions, this is worth asking about in writing rather than assuming the standard answer applies to you.

The underspent test, which decides whether you get an offer

Where the conditions are met, the plan does not have to offer you FSA continuation at all unless, on the date of your qualifying event, the benefit still available to you for the rest of the plan year exceeds the most the plan could charge you in premiums for that same remainder.

The arithmetic is short:

Notice what the premium is built from. It is your own election plus any employer contribution, and nothing else. Continuing an FSA means paying your own money back to yourself, with a 2% surcharge, in after-tax dollars. That is why the underspent test is really an is-this-worth-it test wearing a different hat.

An overspent account: the offer may never come

You elected $2,400 for a calendar-year FSA, funded at $200 a month, with no employer match. Your job ends on 30 June. By then you have submitted $1,500 of claims.

• Applicable premium: $2,400 a year, so $200 a month.
• Monthly COBRA premium: $200 times 102% = $204.
• Months left in the plan year: July to December, so six.
• Maximum chargeable: 6 times $204 = $1,224.
• Remaining benefit: $2,400 minus $1,500 = $900.

$900 does not exceed $1,224, so the plan has no obligation to offer you continuation, either for the rest of this year or for next. Your account is overspent, which in plain terms means you have already taken out more than the remaining premiums are worth.

An underspent account: the offer comes, and the maths works

Same facts, except you had only submitted $300 of claims by 30 June. Your remaining benefit is $2,100, which does exceed $1,224, so continuation must be offered for the rest of the year.

Paying $1,224 to unlock $2,100 leaves you up to $876 ahead, but only if you actually incur $2,100 of eligible expenses between 1 July and the end of the plan year. Your break-even is at $1,224 of real expenses. Below that you are paying more in premiums than you get back, and the fact that the plan is required to offer you continuation is not a signal that taking it is sensible.

Being offered continuation you should refuse

The regulation lets an administrator skip the per-person arithmetic entirely and send an election notice to everybody, purely to save itself the trouble of working out each account. So an overspent employee can and does receive an FSA election notice. Run the two numbers above before you sign anything. Paying $1,224 to access $900 is not a benefit.

Submitted, not incurred: the receipts in your drawer matter

The underspent test lets the plan deduct claims submitted before the date of the qualifying event. It does not say incurred. Those are different words doing different jobs, and the gap between them is the sharpest piece of planning available on this topic.

An expense you incurred in May but have not yet submitted by your 30 June termination does not reduce your remaining benefit for the purposes of the test. In the example above, $600 of unsubmitted May receipts would have moved you from overspent to underspent, turning a no-offer into an offer worth taking. Meanwhile the expense itself stays claimable, because eligibility for reimbursement turns on when the care was provided, not when you filed the paperwork.

This is not a loophole and it is not aggressive. It is simply that the test is written around submissions, and most people submit continuously out of habit. If you can see a layoff coming and you have receipts sitting unfiled, the timing of when you file them is worth thinking about for a few minutes.

Carryover changes the answer, in your favor, twice

If your plan allows a carryover from last year, IRS guidance sets up an asymmetry that works entirely to your benefit and that hardly anyone writes about.

• Carryover counts toward your remaining benefit. It goes into the numerator of the underspent test, making an offer more likely.
• Carryover does not count toward the premium. The applicable premium is built only from your salary reduction and employer contributions, so carried-over money makes continuation more valuable without making it more expensive.
• Carryover can push continuation past the plan year. If the plan lets active participants carry money into the following year, it must let COBRA beneficiaries do the same on the same terms, and the premium for that carried-over amount is zero. That can run out to the end of your full COBRA period rather than stopping in December.

Take the overspent example again and add $680 of carryover from the prior year. Your remaining benefit becomes $2,400 plus $680 minus $1,500, which is $1,580. That now exceeds $1,224, so continuation must be offered on facts where it otherwise would not have been.

The plan may require you to re-enroll in the FSA to keep a carryover, and may cap it at one year. Both are permitted, so read your plan documents rather than assuming.

If you do not elect: what you can still claim

This is where most of the disappointment on this topic comes from, and it is worth being blunt about.

A run-out period is a deadline for submitting claims, and nothing more. It does not extend the window during which an expense may be incurred. If your coverage ended on 30 June and your plan gives you 90 days of run-out, you have until roughly the end of September to file for care you received on or before 30 June. Care received on 15 July is not reimbursable at all, because on that date you were no longer a participant.

The IRS uses almost exactly this fact pattern in its own example: an employee contributes $600, terminates on 30 June without electing continuation, incurs a $500 medical expense on 15 July, and the plan is prohibited from reimbursing any part of it. Electing COBRA is the only mechanism that keeps the window open, which is the whole reason the election is on the table.

If you are ahead, nobody takes it back

The mirror image is much happier and equally under-explained. Under the uniform coverage rule, your full annual election has to be available to you from the first day of the plan year, regardless of how little you have contributed so far.

So if you elected $2,400, were reimbursed the whole $2,400 in March after only $600 of payroll deductions, and left in June, the employer absorbs the $1,800 difference. There is no provision letting the plan claw it back out of your final paycheck. You are maximally overspent, no continuation will be offered, and you owe nothing. That risk-shifting is the price the employer pays for the arrangement counting as a health plan in the first place.

Dependent care FSAs: no COBRA, but ask about spend-down

COBRA reaches group health plans, and a group health plan is one that provides medical care as defined in the tax code. Dependent care assistance reimburses childcare and elder care, not medical care, so it falls outside the definition. The cafeteria plan regulations make the separation explicit by prohibiting a health FSA from reimbursing dependent care expenses at all.

Be aware this is a conclusion drawn from definitions rather than a sentence in a regulation saying "dependent care FSAs are exempt from COBRA". No such sentence exists. The conclusion is not controversial, but you should know what it rests on.

What does exist, and what is genuinely useful, is the optional spend-down. A cafeteria plan is permitted to provide that dependent care expenses incurred after you stop participating, through the end of that plan year, may still be reimbursed from your unused balance. It is optional, so your plan may or may not have it, and the answer is in your plan document rather than in the law.

That single question, asked of your administrator on the way out, is the difference between recovering a dependent care balance and forfeiting it. Almost nobody asks it, because almost nobody knows the provision exists.

Can an FSA pay your COBRA premiums?

No. The regulation names this exact case, prohibiting a health FSA from reimbursing "premiums for COBRA coverage" alongside long-term care and other insurance premiums. IRS Publication 969 says the same thing in plainer words: an FSA cannot distribute money for health insurance premiums.

There is a nuance that gets lost because two different things share the name "cafeteria plan". Your health FSA is one component of a cafeteria plan. A separate component handles premium payments, and COBRA premiums can be qualified benefits there. The regulations even work an example of a newly hired employee paying premiums for a former employer's COBRA coverage through their new employer's cafeteria plan. Whether your new employer's plan actually permits it is a question for them.

The genuinely reliable route to paying COBRA with untaxed money is an HSA, which can pay COBRA premiums tax free by statute. That is covered in paying COBRA premiums from an HSA, and it beats every other option in this section for almost everyone who has one.

A note on HRAs

If your employer funded a health reimbursement arrangement rather than an FSA, COBRA applies to that too, but with none of the escape hatches above. There is no shortened obligation, so the continuation period runs the full 18 or 36 months, and the premium is an actuarial estimate rather than a figure read off your own election. The amount continued is your maximum reimbursement balance as at the qualifying event.

What to ask your administrator, in writing

Every question below has an answer that changes the money, and every one of them is a fair question that a competent administrator can answer quickly. Ask by email so you have the reply.

• What was my remaining health FSA benefit as of the date of my qualifying event?
• Which claims had been submitted as of that date, and for how much?
• What is the monthly continuation premium, and how many months would I be charged for?
• Is my FSA an excepted benefit, and does the shortened continuation period apply to me?
• Does the plan allow a carryover, and does my carryover balance count toward my remaining benefit?
• How long is the run-out period, and what is the last date I can submit claims?
• For a dependent care FSA: does the plan include the optional spend-down provision?

The short version

Continuing a health FSA is worth doing in one situation and one only: you have put in noticeably more than you have taken out, and you can name the expenses you will genuinely incur before the plan year ends. In every other case the 102% premium is a bad way to buy back your own money.

Your medical coverage is the decision with real money attached, and it is a separate election. Work out what that would cost with the calculator, check the clocks in the deadline guide, and treat the FSA question as the small, separate arithmetic problem it is.
